  Title [A meta-analysis for comparing dry matter intake prediction models in dairy goats] Type (up) Book Chapter
  Year 2011 Publication XIV Jornadas sobre Produccion Animal, Zaragoza, Espana, 17 y 18 de mayo de 2011 Abbreviated Journal

  Keywords Dairy Animals [LL110]; Animal Nutrition (Production Responses) [LL520]; Mathematics and Statistics [ZZ100]; body weight; dairy performance; dry matter; feed intake; meta-analysis; milk fat; milk yield; milk yielding animals; models; performance traits; goats; [Indexed using CAB Thesaurus terms]  
  Abstract Currently available models for dairy goats (INRA, 2007; NRC, 2007; Avondo et al., 2008) estimated dry matter intake (DMI) from body weight (BW) and milk yield (MY). A model comparison for similar BW showed marked differences in predicted DMI depending on MY (0 to 6 L/d). A meta-analysis of dairy goat intake data published in 125 papers indexed in PubMed and Science Direct was done, resulting in a total of 219 values normally distributed. Milk yield was standardized to 3.5% milk fat (MY3.5%). Goat performances ranged from 29.0 to 85.5 kg BW, 0.4 to 6.2 L/d MY3.5% and 0.8 to 3.5 kg DMI/d. Prediction models were (+or-SEM; P<0.001): DMI (+or-0.099)=1.233+0.370 x MY3.5%; R2=0.69 DMI (+or-0.075)=0.553+0.277 x MY3.5%+0.018 x BW; R2=0.76 The meta-analysis models showed the lowest error of prediction (-0.030 kg DM/d), being lower than those of the Avondo et al. (-0.092 kg DM/d) and INRA (-0.101 kg DM/d) models. On the contrary, the NRC overestimated intake (+0.185 kg DM/d).

  Abstract The British Government spends over <pounds>100 million per annum on the control of bovine tuberculosis (bTB). Improvement in the control through targeted use of diagnostic tests is one focus of eradication plans. The aims were: (a) through systematic literature review identify primary research with estimates of sensitivity (Se) and specificity (Sp) for diagnostic tests for bTB in cattle (b) conduct a statistical meta-analysis to estimate test performance, and (c) using the estimates, model and compare different testing strategies. Of 9782 references reviewed, only 261 met agreed criteria and contained performance estimates for one or more of 14 diagnostic tests. The performance of bTB surveillance systems using the estimates of test performance was affected by the historical probability of herd freedom and the risk of introduction of infection. Where the probability of introduction of infection was high, it was difficult to achieve a high target probability of herd freedom from infection.

  Abstract As endemic goitre was widespread in New Zealand before the introduction of iodized salt, it was assumed that ruminants, particularly dairy cows, may benefit from iodine supplementation although clinical signs of I deficiency are rare. Several trials with sheep have not indicated any significant response in productivity to I supplements, but no definitive trials have been made with dairy cows. Estimates of pasture I concentrations are variable and requirements for lactating cows are imprecise. To ascertain the possibility of a response to I supplements, 2 literature searches, with CAB ABSTRACTS and DIALOG, were made and the procedures involved in each search are described. There were only 3 data sets in which the effect of I supplementation was studied in cows with an inadequate I intake. There was no response in terms of milk production or composition. It is suggested that, in the absence of goitrogens, pasture I less than 500 mu g/kg DM may be adequate for lactating cows but there are insufficient data on pasture or milk I in New Zealand to make an informed judgment on I status in dairy cows.

  Title Human-directed dog aggression: A systematic review Type (up) Book Whole
  Year 2012 Publication Thesis Abbreviated Journal  
  Volume Issue Pages  
  Keywords dogs; aggression; bite; behaviour; epidemiology; risk factor  
  Abstract Human-directed dog aggression is a worldwide issue with major public health and animal welfare implications. Consequences for the target of aggression range from fear and minor injury, to life threatening injury and death, and for the dog impaired freedoms, restricted interactions and ultimately euthanasia. The systematic review undertaken here aimed to identify and assimilate all robust evidence regarding factors that affect the risk of human-directed dog aggression. Such information is vital for the development of sound preventive strategies. Multiple electronic literature databases were interrogated in order to identify all evidence for risk factors of human-directed dog aggression. The search strategy was designed to minimise the risk of publication and language biases, specificity was sacrificed for sensitivity. The threshold for acceptance of evidence was predetermined at a moderate level; any study that provided evidence with a low risk of confounding and bias and a moderate probability that any relationship identified was causal would reach the final review. Appraisal examined methodological quality, study design, selection process, measurement of outcome and exposures, and type and quality of analysis. All stages of appraisal were undertaken blind to the study findings. On assimilating the evidence identified, no robust evidence for any risk factors of human-directed dog aggression was identified. Eight studies provided a moderate level of somewhat conflicting evidence. Amongst those studies appraised as failing to reach the moderate level of acceptable evidence, the majority were excluded as a result of multiple limitations. It is vital that future research is undertaken to a high methodological standard in order that it provides robust evidence for the effect of any risk factor identified.

  Abstract The contaminated meat and milk of cattle can transmit several diseases, like bovine tuberculosis, to humans. These diseases are usually zoonotic and occur worldwide causing losses in cattle farms and risking the health of the consumers. The purpose of this study was to determine the magnitude of the meat and milk black market in Brazil. A bibliographical review of national and international publications was carried out by consulting Acervo, Higeia, Dedalus, Medline, Lilacs and Cab-abstract databases, besides the internet and newspaper articles. In this study, the aspects concerning the importance of tuberculosis caused by Mycobacterium bovis in man and animals is approached since its magnitude is still unknown in Brazil. It was observed that the meat and milk black markets needs urgent adoption of sanitary measures since they are one of causes of the public health problems in the country.

  Title Onset of diarrhea and pyrexia and time to detection of Salmonella enterica subsp enterica in feces in experimental studies of cattle, horses, goats, and sheep after infection per os Type (up) Journal Article
  Year 2011 Publication Journal of the American Veterinary Medical Association Abbreviated Journal J Am Vet Med Assoc  
  Volume 238 Issue 10 Pages 1333-1339  
  Keywords Animals; Diarrhea/microbiology/pathology/veterinary; Feces/microbiology; Fever/microbiology/pathology/veterinary; Salmonella Infections, Animal/microbiology/pathology; Salmonella enterica/physiology; Species Specificity; Cattle; Horses; Goats; Sheep  
  Abstract OBJECTIVE: To determine time to first detection of Salmonella organisms in feces of animals after experimental infection PO and times to onset of diarrhea and pyrexia to evaluate a common method for identifying nosocomial infections on the basis of time of admission and onset of clinical signs (ie, the 3-day criterion). DESIGN: Meta-analysis. SAMPLE POPULATION: Cattle, horses, goats, and sheep experimentally infected PO with Salmonella enterica subsp enterica. PROCEDURES: Online databases were searched for published reports describing results of experimental infection of cattle, horses, goats, and sheep PO with salmonellae. Time to detection of organisms in feces as well as to onset of diarrhea and pyrexia was noted. Analysis of covariance was used to examine relationships among these variables, host species and age, and Salmonella serovar and magnitude of infecting dose. RESULTS: Forty-three studies met the criteria for inclusion. Time to detection of salmonellae in feces ranged from 0.5 to 4 days. Times to onset of diarrhea and pyrexia ranged from 0.33 to 11 days and from 0.27 to 5 days, respectively. Time to onset of diarrhea was related to host age and Salmonella serovar. No other associations were identified. CONCLUSIONS AND CLINICAL RELEVANCE: Time to detection of salmonellae in feces is unreliable for identifying hospital-acquired infections; a 3-day criterion will misidentify hospital- versus community-acquired infections. Relying on clinical indices such as times to onset of diarrhea and pyrexia to trigger fecal sampling for detection of Salmonella infection will increase the risk of environmental contamination and nosocomial spread because animals may begin shedding organisms in feces several days prior.

  Abstract SUMMARY Cryptosporidium is a zoonotic protozoan parasite with public health importance worldwide. The objectives of this study were to (1) conduct a meta-analysis of published literature for oocyst shedding and diarrhoea outcomes, and (2) develop recommendations for standardization of experimental dose-response studies. Results showed that for the outcome of oocyst shedding in faeces, the covariates 'experimental species', 'immunosuppression', 'oocyst dose' and 'oocyst dose' x 'age' were all significant (P 0.05). This study suggests that exposing mice, piglets, or ruminants, and using immunosuppressed experimental hosts, is more likely to result in oocyst shedding. For the outcome of diarrhoea in experimentally infected animal species, the key covariates 'experimental species', 'age' and 'immunosuppression' were significant (P 0.2). Therefore, based on the results of this meta-analysis, these variables should be carefully reported and considered when designing experimental dose-response studies. Additionally, detection of possible publication bias highlights the need to publish additional studies that convey statistically non-significant as well as significant results in the future.

  Keywords Animal Husbandry/methods; Animals; Campylobacter Infections/etiology/prevention & control/transmission; Chickens/microbiology; Food Microbiology; Housing, Animal; Poultry Diseases/prevention & control; Chickens  
  Abstract AIMS: Produce an evidence-based ranking of the major contributing factors and sources of Campylobacter occurrence in broilers produced in England, Scotland and Wales – Great Britain (GB). METHOD AND RESULTS: Relevant data were extracted from 159 research papers and findings were grouped into 14 sources of on-farm contamination and 37 contributing factors. A relevancy score was developed to take into account various measures from each study of applicability to GB broilers and strength of findings. Results indicate that major sources of Campylobacter include a depopulation event, another house on-farm, on-farm staff, and other animals on farm. The depopulation schedule (staggered slaughter) and multiple houses on-farm were identified as contributing factors associated with increasing the risk, and those decreasing the risk were use of a hygiene barrier, parent company and certain seasons of rearing. CONCLUSIONS: Although the review was more resource intensive compared to narrative studies, the system allows an increased level of transparency and the ability to investigate patterns and trends. SIGNIFICANCE AND IMPACT OF THE STUDY: This paper provides the first evidence-based ranking of the major sources and contributing factors for Campylobacter presence in broilers in GB using a systematic review.

  Abstract A systematic review of investigations on productivity, mortality and cannibalism of laying hens housed in aviaries is presented. In Part One we reviewed the studies that compared these parameters between laying hens housed in aviaries and in conventional cages. In Part Two we investigated the relative impact of strain, beak trimming and rearing condition on productivity and mortality in aviaries. The comparative analysis revealed that aviary hens consumed 3.0% more food than caged hens, and food conversion was 6.7% higher in aviaries than in cages. On the other hand, the mortality rate and cannibalism rate did not differ significantly between the two housing systems. The analysis of causes of variation in productivity, mortality rate and cannibalism rate in aviaries revealed a strong effect of strain. Beak trimming was associated with a reduced prevalence of cannibalism rates but had no effect on overall mortality. It also reduced egg weight and food consumption. Early access to litter during the rearing period had a positive effect on egg weight; egg mass, food conversion and mortality rate. In conclusion, we found a slightly reduced productivity of aviaries in relation to cages although the mortality rates and the prevalence of cannibalism did not differ between these housing systems. To further improve productivity and reduce mortality of hens housed in aviaries we recommend the choice of suitable strains and the implementation of improved rearing conditions including early access to litter.

  Abstract OBJECTIVE: The purpose of this review was to assess the effects of repeated doses of antenatal corticosteroids on lung and brain function and on growth restriction in animals. STUDY DESIGN: MEDLINE and EMBASE were searched for randomized controlled trials that compared repeated doses of antenatal corticosteroids versus a single dose, with or without placebo, in pregnant animals. RESULTS: Nineteen studies were included. The animals that were studied included sheep, monkeys, rabbits, and mice. There were 8 studies that assessed the effects of repeated doses of antenatal corticosteroids on lung function. All the studies reported improvement in lung function after repeated doses of antenatal corticosteroids. Seven studies investigated the effects of repeated doses of antenatal corticosteroids on brain or nervous system function or growth; all the studies found adverse effects with repeated doses of antenatal corticosteroids. Eleven studies looked at the effect of repeated doses of antenatal corticosteroids on fetal growth. Nine studies found evidence of fetal growth restriction with repeated doses of antenatal corticosteroids. One study assessed long-term behavioral outcomes in mice and found no effect. CONCLUSION: Evidence from randomized controlled trials in animals suggests that repeated doses of antenatal corticosteroids may have beneficial effects in terms of lung function but may have adverse effects on brain function and fetal growth. Because of the differences between animals and humans, it is difficult to extrapolate directly the results of these studies to humans. Therefore, randomized controlled trials in humans are needed to assess the effects of repeated courses of antenatal corticosteroids for pregnant women who are at increased risk of preterm birth in terms of important perinatal, neonatal, and maternal outcomes.

  Abstract The objective of this study was to examine whether animal studies can reliably be used to determine the usefulness of methylprednisolone (MP) and other treatments for acute spinal cord injury (SCI) in humans. This was achieved by performing a systematic review of animal studies on the effects of MP administration on the functional outcome of acute SCI. Data were extracted from the published articles relating to: outcome; MP dosing regimen; species/strain; number of animals; methodological quality; type of injury induction; use of anaesthesia; functional scale used; and duration of follow-up. Subgroup analyses were performed, based on species or strain, injury method, MP dosing regimen, functional outcome measured, and methodological quality. Sixty-two studies were included, which involved a wide variety of animal species and strains. Overall, beneficial effects of MP administration were obtained in 34% of the studies, no effects in 58%, and mixed results in 8%. The results were inconsistent both among and within species, even when attempts were made to detect any patterns in the results through subgroup analyses. The results of this study demonstrate the barriers to the accurate prediction from animal studies of the effectiveness of MP in the treatment of acute SCI in humans. This underscores the need for the development and implementation of validated testing methods.

  Abstract There are numerous treatments for correction of dorsal displacement of the soft palate (DDSP). However, the efficacy of these treatments is controversial and there is little consensus on how best to treat this condition. The aims of this study were to systematically review the literature and to assess the evidence on the clinical effects of interventions for dynamic intermittent DDSP. A secondary objective was to assess whether factors relating to study quality affected reported success rates. Twenty-three studies were included, covering a wide number of interventions but also differing widely is terms of study design, sample size, method of diagnosis, outcome measure and the number lost to follow-up. The assessment of adverse effects was severely limited because of lack of reporting. The way in which success is measured appears to have a great effect on the reported results. Research synthesis has been severely limited because of the heterogeneity in the included studies. The low level of evidence makes it difficult to draw firm conclusions as to the efficacy of procedures for DDSP. Hence it is currently not possible to determine which procedure is the most appropriate. This systematic review highlights the difficulties of studying palatal dysfunction and suggests areas where improvements can be made in future studies.

  Title Meta-analytical study of productive and nutritional interactions of mycotoxins in growing pigs Type (up) Journal Article
  Year 2012 Publication Animal : an International Journal of Animal Bioscience Abbreviated Journal Animal  
  Volume 6 Issue 9 Pages 1476-1482  
  Keywords Age Factors; Animal Feed/analysis/microbiology; Animal Nutritional Physiological Phenomena; Animals; Feeding Behavior/drug effects; Female; Food Contamination; Male; Mycotoxins/metabolism/toxicity; Organ Size/drug effects; Sex Factors; Swine/growth & development/microbiology/physiology; Weight Gain/drug effects; Pigs; Swine  
  Abstract A meta-analysis was carried out in order to study the association of mycotoxins with performance and organ weights in growing pigs. A total of 85 articles published between 1968 and 2010 were used, totaling 1012 treatments and 13 196 animals. The meta-analysis followed three sequential analyses: graphical, correlation and variance-covariance. The presence of mycotoxins in diets was seen to reduce the feed intake by 18% and the weight gain in 21% compared with the control group. Deoxynivalenol and aflatoxins were the mycotoxins with the greatest impact on the feed intake and growth of pigs, reducing by 26% and 16% in the feed intake and by 26% and 22% in the weight gain. The mycotoxin concentration in diets and the animal age at challenge were the variables that more improved the coefficient of determination in equations for estimating the effect of mycotoxins on weight gain. The mycotoxin effect on growth proved to be greater in younger animals. In addition, the residual analysis showed that the greater part of the variation in weight gain was explained by the variation in feed intake (87%). The protein and methionine levels in diets could influence the feed intake and the weight gain in challenged animals. The weight gain in challenged pigs showed a positive correlation with the methionine level in diets (0.68). The mycotoxin effect on growth was greater in males compared with the effect on females. The reduction in weight gain was of 15% in the female group and 19% in the male group. Mycotoxin presence in pig diets has interfered in the relative weight of the liver, the kidneys and the heart. Mycotoxins have an influence on performance and organ weight in pigs. However, the magnitude of the effects varies with the type and concentration of mycotoxin, sex and the animal age, as well as nutritional factors.

  Title Anti-methanogenic effects of monensin in dairy and beef cattle: A meta-analysis Type (up) Journal Article
  Year 2013 Publication Journal of Dairy Science Abbreviated Journal J Dairy Sci  
  Volume 96 Issue 8 Pages 5161-5173  
  Keywords Animals; Cattle/metabolism; Female; Male; Methane/antagonists & inhibitors; Methane/biosynthesis; Monensin/pharmacology; Monensin; Methane; Cattle  
  Abstract Monensin is a widely used feed additive with the potential to minimize methane (CH4) emissions from cattle. Several studies have investigated the effects of monensin on CH4, but findings have been inconsistent. The objective of the present study was to conduct meta-analyses to quantitatively summarize the effect of monensin on CH4 production (g/d) and the percentage of dietary gross energy lost as CH4 (Ym) in dairy cows and beef steers. Data from 22 controlled studies were used. Heterogeneity of the monensin effects were estimated using random effect models. Due to significant heterogeneity (>68%) in both dairy and beef studies, the random effect models were then extended to mixed effect models by including fixed effects of DMI, dietary nutrient contents, monensin dose, and length of monensin treatment period. Monensin reduced Ym from 5.97 to 5.43% and diets with greater neutral detergent fiber contents (g/kg of dry matter) tended to enhance the monensin effect on CH4 in beef steers. When adjusted for the neutral detergent fiber effect, monensin supplementation [average 32 mg/kg of dry matter intake (DMI)] reduced CH4 emissions from beef steers by 19 +/- 4 g/d. Dietary ether extract content and DMI had a positive and a negative effect on monensin in dairy cows, respectively. When adjusted for these 2 effects in the final mixed-effect model, monensin feeding (average 21 mg/kg of DMI) was associated with a 6 +/- 3 g/d reduction in CH4 emissions in dairy cows. When analyzed across dairy and beef cattle studies, DMI or monensin dose (mg/kg of DMI) tended to decrease or increase the effect of monensin in reducing methane emissions, respectively. Methane mitigation effects of monensin in dairy cows (-12 +/- 6 g/d) and beef steers (-14 +/- 6 g/d) became similar when adjusted for the monensin dose differences between dairy cow and beef steer studies. When adjusted for DMI differences, monensin reduced Ym in dairy cows (-0.23 +/- 0.14) and beef steers (-0.33 +/- 0.16). Monensin treatment period length did not significantly modify the monensin effects in dairy cow or beef steer studies. Overall, monensin had stronger antimethanogenic effects in beef steers than dairy cows, but the effects in dairy cows could potentially be improved by dietary composition modifications and increasing the monensin dose.

  Title Applications of evidence-based medicine: cranial cruciate ligament injury repair in the dog Type (up) Journal Article
  Year 2005 Publication Veterinary Surgery : VS Abbreviated Journal Vet Surg  
  Volume 34 Issue 2 Pages 93-98  
  Keywords Animals; Anterior Cruciate Ligament/injuries/surgery; Dogs/injuries/surgery; Evidence-Based Medicine; Lameness, Animal/surgery; Retrospective Studies; Stifle/injuries; Surgical Procedures, Operative/methods/veterinary; Treatment Outcome; Dogs  
  Abstract OBJECTIVE: To evaluate the literature reporting surgical interventions pertaining to canine cranial cruciate ligament (CCL) injury using an evidence-based medicine paradigm. STUDY DESIGN: Systematic literature review. METHODS: An on-line bibliographic search through Medline, PubMed, Veterinary Information Network, and Commonwealth Agricultural Bureau Abstracts was performed during August 2004. Two hundred and forty resources of information were identified. Studies were compared and evaluated with regard to study design (retrospective, prospective, randomization), surgical technique, short- and long-term follow-up, and evidence classification. RESULTS: Twenty-eight resources qualified to assist with evidence classification. No class I or class II studies were present, 5 studies were categorized as a class III and 23 studies were categorized as a class IV. Seventeen studies were retrospectively designed and 11 studies were prospectively designed. Proposed results ranged from a wide variety of subjective findings including clinical impression, radiographic analysis, synovial fluid analysis, gross pathology, and histopathology. Objective results, although infrequent, included force plate analysis and cadaveric biomechanical testing. CONCLUSIONS: At this time, the application of evidence-based medicine in analyzing the current available evidence suggests that there is not a single surgical procedure that has enough data to recommend that it can consistently return dogs to normal function after CCL injury. The requirement for assessing and categorizing the available evidence becomes increasingly important as more data becomes available and the quality of research improves. CLINICAL RELEVANCE: An evidence-based medicine paradigm did not provide sufficient evidence favoring 1 surgical technique for management of canine CCL injury.

  Abstract OBJECTIVE: To identify and critically evaluate the quality of evidence of the most commonly used pharmacologic, nutraceutical, and purported slow-acting drugs of osteoarthritis for the management of osteoarthritis in dogs by use of the FDA's evidence-based medicine scoring system. DESIGN: Systematic review. SAMPLE POPULATION: 16 clinical trials. PROCEDURES: A broad bibliographic search was performed prior to May 2006. Inclusion criteria focused on prospective trials evaluating commonly used medical treatment interventions for the management of osteoarthritis in dogs and published in peer-reviewed journals. The analysis consisted of the following: study design rating, quality factor rating, quantity rating, consistency rating, relevance to disease risk reduction rating, and cumulative strength of evidence ranking. RESULTS: 4 trials evaluating meloxicam were rated as type I. Three trials evaluating carprofen were rated as type I, and 2 trials were rated as type III. One trial evaluating each of the following agents was rated as type 1: etodolac; P54FP; polysulfated glycosaminoglycan; and a combination of chondroitin sulfate, glucosamine hydrochloride, and manganese ascorbate. Two trials evaluating pentosan polysulphate and 2 trails evaluating green-lipped mussels were rated as type I. One trial evaluating hyaluronan was rated as type III. CONCLUSIONS AND CLINICAL RELEVANCE: A high level of comfort exists for meloxicam that the claimed relationship is scientifically valid and that its use is clinically efficacious for the treatment of osteoarthritis in dogs. A moderate level of comfort exists for carprofen; etodolac; pentosan polysulphate; green-lipped mussels; P54FP; polysulfated glycosaminoglycans; and a combination of chondroitin sulfate, glucosamine hydrochloride, and manganese ascorbate. An extremely low level of comfort exists for hyaluronan.

  Abstract The study was carried out to elaborate response surface models through broiler performance data recovered from literature in order to predict performance and develop economic analysis. Three hundred and twenty eight studies published between 2005 and 2009 were retrieved using the systematic review of literature method. Average weight gain and feed intake data were collected from twelve studies that fulfilled the preestablished inclusion criteria, and response surface models were adjusted with metabolizable energy, environmental temperature, and slaughter age as independent variables. The models for weight gain (R2=0.88) and feed conversion (R2=0.87) were accurate, precise, and not biased. There was no interaction between metabolizable energy and environmental temperature on weight gain and feed intake. The independent variables age and temperature showed interaction for weight gain and feed conversion, whereas the interaction between age and metabolizable energy was detected only for weight gain. It was possible to elaborate economic analysis to determine maximum profit, as a function of the variables included in the model, in different market situations determined by changes in broiler and feed prices. Response surface models are effective to predict broiler chickens performance and allow the development of economic analysis to optimize profitability according to market prices.

  Title Board invited review: The importance of the gestation period for welfare of calves: maternal stressors and difficult births Type (up) Journal Article
  Year 2012 Publication Journal of Animal Science Abbreviated Journal J Anim Sci  
  Volume 90 Issue 13 Pages 5021-5034  
  Keywords Animal Welfare; Animals; Animals, Newborn/physiology; Cattle/physiology; Female; Male; Parturition; Pregnancy; Stress, Physiological; Cattle  
  Abstract The prenatal period is of critical importance in defining how individuals respond to their environment throughout life. Stress experienced by pregnant females has been shown to have detrimental effects on offspring biology in humans and a variety of other species. It also is becoming increasingly apparent that prenatal events can have important consequences for the behavior, health, and productivity of offspring in farmed species. Pregnant cattle may experience many potentially important stressors, for instance, relating to their social environment, housing system and physical environment, interactions with humans and husbandry procedures, and their state of health. We examined the available literature to provide a review of the implications of prenatal stress for offspring welfare in cattle. The long-term effects of dystocia on cattle offspring also are reviewed. To ensure a transparent and repeatable selection process, a systematic review approach was adopted. The research literature clearly demonstrates that prenatal stress and difficult births in beef and dairy cattle both have implications for offspring welfare and performance. Common husbandry practices, such as transport, were shown to influence offspring biology and the importance of environmental variables, including thermal stress and drought, also were highlighted. Maternal disease during pregnancy was shown to negatively impact offspring welfare. Moreover, dystocia-affected calves suffer increased mortality and morbidity, decreased transfer of passive immunity, and important physiological and behavioral changes. This review also identified considerable gaps in our knowledge and understanding of the effects of prenatal stress in cattle.

  Title Meta-analysis on the effects of the physical environment, animal traits, feeder and feed characteristics on the feeding behaviour and performance of growing-finishing pigs Type (up) Journal Article
  Year 2012 Publication Animal : an International Journal of Animal Bioscience Abbreviated Journal Animal  
  Volume 6 Issue 8 Pages 1275-1289

  Abstract A meta-analysis, using information from 45 experiments on growing-finishing pigs published in 39 manuscripts, was carried out to determine the simultaneous effects of the physical environment (space allowance, group size, flooring conditions, temperature, presence of enrichment), pig traits (initial body weight (BW) for each studied time interval, sex, genetics), feeder characteristics (water provision within the feeder, feeder design (individual/collective), feeder places/pig, presence of feeder protection) and feed characteristics (feed allowance (ad libitum/restricted), net energy content, crude protein (CP) content), as well as their potential interactions, on the feeding behaviour and performance of growing-finishing pigs. The detrimental effect of low temperature on performance was particularly evident for restricted-fed pigs (P < 0.05). At reduced feeder space allowance, a reduction in the percentage of time spent eating was predicted when increasing initial BW, whereas the opposite was predicted for larger feeder space allowances (P < 0.001). The reduction in visit duration to the feeder in higher BW groups became gradually more important with increasing feeder space allowance (P < 0.01), whereas the increase in the ingestion rate and average daily feed intake (ADFI) with increasing initial BW became smaller with increasing feeder space (P < 0.05). The model predicted a reduction in feed conversion ratio (FCR) with increasing group size (P < 0.05) and floor space allowance (P < 0.01) and on solid floors with or without bedding (P < 0.05). In comparison with other feeders, wet/dry feeders were associated with more frequent but shorter feeder visits (P < 0.05), higher ingestion rates (P < 0.001) and higher ADFI (P < 0.10). The use of protection within individual feeders increased the time spent feeding (P < 0.001), reduced the number of visits per day (P < 0.01), the ingestion rate (P < 0.001) and FCR (P < 0.01) in comparison with other feeder types. Sex modulated the effect of the number of feeder places/pig on FCR (P < 0.05), with a gradual reduction of FCR in entire males and females when increasing feeder space allowance. Genetics tended to modulate the effect of diets' CP content on FCR (P < 0.10). Overall, these results may contribute to the improvement of the welfare and performance of growing-finishing pigs by a better knowledge of the influence of the rearing environment and may help optimize the feeding strategies in current production systems.
