Title (up) Injury risks among chimpanzees in three housing conditions Type Journal Article
Year 2000 Publication American journal of primatology Abbreviated Journal Am. J. Primatol.
Volume 51 Issue 3 Pages 161-175
Keywords Aggression; *Animal Welfare; Animals; Female; *Housing, Animal; Male; *Pan troglodytes; Risk Assessment; Wounds and Injuries/*veterinary
Abstract Meeting the psychological needs of chimpanzees (Pan troglodytes) can be a challenge given their aggressiveness on the one hand and the complexity of their social lives on the other. It is unclear how to balance the need to provide opportunities for species-appropriate behavior against potential risks of injury chimpanzees may inflict on each other. This study evaluates the suggestion that simpler social environments protect chimpanzees from wounding. Over a two-year period all visible injuries to 46 adult males, 64 adult females, and 25 immature chimpanzees were recorded at the Yerkes Regional Primate Research Center. Approximately half of the subjects were mother-reared, and the rest were nursery-reared. Housing included compounds containing about 20 chimpanzees, interconnected indoor-outdoor runs for groups of up to 12 individuals, and smaller indoor-outdoor runs for pairs and trios. Annual wounding rates were calculated for serious wounds (extensive injuries and all those requiring veterinary intervention) as well as for minor wounds. Compound-housed chimpanzees incurred the highest level of minor wounding, but serious wounding levels were not affected by housing condition. Even with a period of dominance instability and elevated levels of wounding in one compound, compound chimpanzees were not injured more than those in smaller social groups over the long term. Nursery-reared females in moderate-sized groups were wounded more than mother-reared females. Also, nursery-reared males and females were wounded less often when paired with mother-reared companions. Overall, this study indicates that maintaining chimpanzees in pairs and trios would not be an effective means for reducing injuries. The management of wounding in chimpanzee colonies is influenced more by the sex and rearing composition of a colony.

Title (up) Investigation of palpation as a method for determining the prevalence of keel and furculum damage in laying hens Type Journal Article
Year 2004 Publication The Veterinary record Abbreviated Journal Vet. Rec.
Volume 155 Issue 18 Pages 547-549
Keywords Animal Husbandry/methods; Animal Welfare; Animals; Bone and Bones/*injuries; Chickens/*injuries; Female; Fractures, Bone/diagnosis/epidemiology/*veterinary; Great Britain/epidemiology; Housing, Animal/standards; Oviposition; Palpation/methods/*veterinary; Poultry Diseases/*diagnosis/epidemiology; Prevalence; Sensitivity and Specificity
Abstract Old breaks of the keel and furculum were identified by palpation in 500 end-of-lay hens from 10 flocks housed in free-range and barn systems, and the results were compared with the results obtained by a full dissection and inspection. The method was considered to be sufficiently precise to be used as a diagnostic tool although people using it would need to be trained. The results obtained by dissection indicated that 50 to 78 per cent of the birds in the flocks had breaks of the furculum and keel, but no other breaks of bones were detected.

Title (up) Personality influences tetanus-specific antibody response in adult male rhesus macaques after removal from natal group and housing relocation Type Journal Article
Year 2003 Publication American journal of primatology Abbreviated Journal Am. J. Primatol.
Volume 61 Issue 2 Pages 73-83
Keywords Analysis of Variance; Animals; Antibody Formation; Enzyme-Linked Immunosorbent Assay; Housing, Animal; Immunization, Secondary/*veterinary; Immunoglobulin G/blood; Macaca mulatta/*immunology/physiology; Male; *Personality; Social Behavior; Tetanus Toxoid/*immunology
Abstract Previous research has suggested that personality is related to immune function in macaques. Using a prospective design, we examined whether variation in the personality dimension “Sociability” in adult male rhesus macaques (Macaca mulatta) was related to the in vivo secondary antibody response to a tetanus toxoid booster immunization following removal from natal groups and relocation to individual housing. We also explored whether the timing of the immunization following relocation had an impact on the immune response. Blood was sampled at the time of booster immunization, at 14 and 28 days post-immunization, and approximately 9 months post-immunization. Plasma was assayed for tetanus-specific IgG by enzyme-linked immunoassay (ELISA). There was no difference between High- and Low-Sociable animals in antibody levels at the time of the booster immunization. Multivariate analysis of variance (MANOVA) revealed that High-Sociable animals had a significantly higher antibody response following relocation and immunization compared to Low-Sociable animals. There was no effect of timing of the immunization on the immune response. The results confirm that personality factors can affect animals' immune responses, and that the dimension Sociability may be influential in a male's response to social separation and relocation.

Title (up) Preliminary study to examine the utility of using foot burn or hock burn to assess aspects of housing conditions for broiler chicken Type Journal Article
Year 2006 Publication British poultry science Abbreviated Journal Br Poult Sci
Volume 47 Issue 1 Pages 13-18
Keywords Animal Husbandry; *Animal Welfare; Animals; Chickens; Dermatitis, Contact/diagnosis/pathology/*veterinary; Feathers; Female; Foot Diseases/diagnosis/pathology/*veterinary; *Housing, Animal; Male; Poultry Diseases/diagnosis/*pathology; Skin/pathology
Abstract 1. Eleven broiler chicken farms, representing 4 production system types, were visited during the last 5 d of the flock cycle: bird and flock details were recorded. Litter friability was assessed at 9 sites within the house, atmospheric ammonia was measured at three sites and bird cleanliness was assessed on a numerical rating scale. 2. For these flocks, hock burn, foot burn and breast burn were measured at the processing plant by standardised assessors. 3. Significant correlations were identified between the percentage of birds with foot burn and average litter score, average house ammonia concentrations and feather score. 4. No correlation was found between the percentage of birds with hock burn or breast burn and average litter scores, average ammonia concentrations or feather score. 5. No correlation was found between stocking density and foot burn, hock burn or breast burn.6. If confirmed, these findings may have implications for the draft EU Broiler Directive, for which it is proposed that permitted stocking density on farm may be determined by the incidence and severity of contact dermatitis measured on plant.

Title (up) Risk factors associated with behavioural disorders of crib-biting, weaving and box-walking in Swiss horses Type Journal Article
Year 2003 Publication Equine Veterinary Journal Abbreviated Journal Equine Vet J
Volume 35 Issue 2 Pages 158-163
Keywords Animal Husbandry/*methods; Animals; *Behavior, Animal; Confounding Factors (Epidemiology); Data Collection; Female; Horse Diseases/epidemiology/*etiology/prevention & control; Horses; *Housing, Animal; Male; Mental Disorders/epidemiology/etiology/prevention & control/*veterinary; Prevalence; Regression Analysis; Risk Factors; *Stereotyped Behavior; Switzerland/epidemiology
Abstract REASONS FOR PERFORMING STUDY: Studies on the prevalence of behavioural disorders in horses and on associated risk factors have revealed inconsistent results. There are many studies on the neuropharmacological, surgical or mechanical therapy of stereotypies, but little is known about their causation. OBJECTIVES: To explore risk factors associated with the occurrence of behavioural disorders in horses. METHODS: A sample of horse owners, selected randomly and representative for Switzerland, was contacted in a postal survey. Answers were provided for 622 stables (response rate 35.2%). Individual data of 2,341 horses were examined with path analysis (multivariable linear and logistic regression), and adjustment made for possible confounding effects due to age and breed. RESULTS: Out of 60 possible risk factors, 11 were associated with the outcome at the univariable level (null-hypothesis path model) and 3 factors remained after the backward logistic regression procedure. Mature Warmbloods and Thoroughbreds, assessed by the owners to be reactive, fed 4 times a day and without daily pasture, had increased odds of displaying crib-biting, weaving and box-walking. Furthermore, indirect associations of 5 factors with the outcome were identified. CONCLUSIONS: The final logistic regression model of risk factors leads to the hypotheses that causal prevention of stereotypic behaviours should be based upon housing and management conditions which allow tactile contact with other horses (e.g. mutual grooming), daily free movement (paddock or pasture), as well as the provision of high amounts of roughage but of little or no concentrates. POTENTIAL CLINICAL RELEVANCE: It is one of the aims of population medicine to prevent the development of behavioural disorders. Further research is needed to test the concluding hypotheses in experimental studies or to verify them in the context of similar observational studies.

Title (up) Strain and age differences in behaviour, fear response and pecking tendency in laying hens Type Journal Article
Year 2003 Publication British poultry science Abbreviated Journal Br Poult Sci
Volume 44 Issue 3 Pages 333-344
Keywords Age Factors; Aggression/*physiology; Animal Husbandry; Animals; *Behavior, Animal; Breeding; Chickens/genetics/*physiology; Fear/*physiology; Feathers/*injuries; Female; Housing, Animal; Population Density; Social Behavior
Abstract 1. Behaviours associated with a high or low tendency to feather peck could be used as predictors of feather pecking behaviour in selective breeding programmes. This study investigated how strain and age at testing influenced responses in behavioural tests. 2. Four layer-type strains (ISA Brown, Columbian Blacktail, Ixworth and a high feather pecking (HP) and a low feather pecking (LP) line of White Leghorn) were reared in 6 same-strain/line pens of 8 birds from one day old. Birds in half the pens were given an open field test, a novel object test and a test with loose feather bundles between 4 and 12 weeks of age and a tonic immobility (TI) test at 13 weeks of age. All pens were tested with fixed feather bundles at 26 weeks, and undisturbed behaviour in the home pens was videoed at 1 and 27 weeks of age. Daily records of plumage damage were used as an indicator of feather pecking activity in the home pens. 3. Strain did not influence novel object test, open field test or loose feather test behaviour, although age effects in all three tests indicated a reduction in fearfulness and/or an increase in exploratory behaviour with increasing age. 4. White Leghorns showed longer TI durations than the other strains but less pecking at fixed feather bundles than ISA Browns and Columbian Blacktails. 5. There were few associations between behaviour in the 5 different tests, indicating that birds did not have overall behavioural traits that were consistent across different contexts. This suggests hens cannot easily be categorised into different behavioural 'types', based on their test responses and casts doubt on the usefulness of tests as predictors of feather pecking.

Title (up) The identification of abnormal behaviour and behavioural problems in stabled horses and their relationship to horse welfare: a comparative review Type Journal Article
Year 1998 Publication Equine Veterinary Journal. Supplement Abbreviated Journal Equine Vet J Suppl
Volume Issue 27 Pages 5-9
Keywords *Animal Welfare; Animals; *Behavior, Animal; Horses/*psychology; *Housing, Animal/standards; *Stereotyped Behavior
Abstract Many behaviours in domestic animals, such as the 'stable vices' of horses, are treated because they are considered undesirable for economic or cultural reasons, and not because the activity affects the horse's quality of life. The impact of a behaviour on the human reporter is not a function of its impact on the animal performer, and an understanding of the causes and effects of the particular activity is necessary to assess the costs and benefits of treatment. Where the behaviour is a sign of poor welfare, such as an inadequate environment, treatment can best be achieved by removing these underlying causal factors. Pharmacological or physical prevention of a behaviour can be justified only if the behaviour causes harm to the performer or to others. In these cases, prevention of the behaviour without addressing its causes is no cure and may result in its perseverance in a modified form or the disruption of the animal's ability to adapt to its environment. Where the behavioural 'problem' causes no harm and is not related to poor housing, then the education of the reporter, rather than treatment of the performer, may be the best solution.

Title (up) The importance of animal cognition in agricultural animal production systems: an overview Type Journal Article
Year 1991 Publication Journal of Animal Science Abbreviated Journal J. Anim Sci.
Volume 69 Issue 12 Pages 5001-5007
Keywords *Agriculture; Animal Population Groups/*psychology; *Animal Welfare; Animals; *Behavior, Animal; *Cognition; Heat; Helplessness, Learned; Housing, Animal/standards; Immobilization; Nesting Behavior; Pain/psychology/veterinary
Abstract To describe and then fulfill agricultural animals' needs, we must learn more about their fundamental psychological and behavioral processes. How does this animal feel? Is that animal suffering? Will we ever be able to know these things? Scientists specializing in animal cognition say that there are numerous problems but that they can be overcome. Recognition by scientists of the notion of animal awareness has been increasing in recent years, because of the work of Griffin and others. Feeling, thinking, remembering, and imagining are cognitive processes that are factors in the economic and humane production of agricultural animals. It has been observed that the animal welfare debate depends on two controversial questions: Do animals have subjective feelings? If they do, can we find indicators that reveal them? Here, indirect behavioral analysis approaches must be taken. Moreover, the linear additivity of several stressor effects on a variety of animal traits suggests that some single phenomenon is acting as a “clearinghouse” for many or all of the stresses acting on an animal at any given time, and this phenomenon might be psychological stress. Specific situations animals may encounter in agricultural production settings are discussed with respect to the animals' subjective feelings.

Title (up) The use of fecal markers to facilitate sample collection in group-housed cats Type Journal Article
Year 2002 Publication Contemporary Topics in Laboratory Animal Science / American Association for Laboratory Animal Science Abbreviated Journal Contemp Top Lab Anim Sci
Volume 41 Issue 2 Pages 51-56

Abstract The provision of proper social housing is a priority when designing an experiment using domestic cats as laboratory animals. When animals are group-housed, studies requiring analysis of stool samples from individual subjects pose difficulty in sample collection and identification. In this study, commercially available concentrated food colorings (known as bakers pastes) were used as fecal markers in group-housed cats. Cats readily consumed 0.5 ml of bakers paste food coloring once daily in canned cat food. Colorings served as fecal markers by imparting a distinct color to each cat s feces, allowing identification in the litter box. In addition, colored glitter (1/8 teaspoon in canned food) was fed to cats and found to be a reliable fecal marker. Long-term feeding of colorings and glitter was found to be safe and effective at yielding readily identifiable stools.
