  1. Environmentally enriching American mink ( Neovison vison) increases lymphoid organ weight and skeletal symmetry, and reveals differences between two sub-types of stereotypic behaviour

    Contributor(s):: Diez-Leon, M., Bursian, S., Galicia, D., Napolitano, A., Palme, R., Mason, G.

    Enrichment studies for wild carnivores (e.g., in zoos) are often short-term, use enrichments of unknown motivational significance, and focus on glucocorticoids and stereotypic behaviour (SB), ignoring other stress-relevant variables. Our study assessed the broad behavioural and physiological...

  2. The influence of gentle interactions on avoidance distance towards humans, weight gain and physiological parameters in group-housed dairy calves

    Contributor(s):: Lurzel, S., Munsch, C., Windschnurer, I., Futschik, A., Palme, R., Waiblinger, S.

    The quality of the relationship between cattle and their caretakers is important for animal welfare and productivity. Nevertheless, the influence of gentle interactions on group-housed dairy calves has not been thoroughly studied so far. We examined the effects of 42 min of gentle interactions...

  4. Effect of different management techniques to enhance colostrum intake on piglets' growth and mortality

    Contributor(s):: Muns, R., Manteca, X., Gasa, J.

    An experiment was conducted to study the effect four different management techniques to enhance colostrum intake had on piglet and litter performance. Treatments were performed on piglets born weighing 1.30 kg or less (SP) within 6 h of birth: control group (CON); split-nursing of the litter for...

  5. Animal housing and welfare: effects of housing conditions on body weight and cortisol in a medium-sized rodent ( Cavia aperea)

    Contributor(s):: Schumann, K., Guenther, A., Jewgenow, K., Trillmich, F.

    Rodents are the most abundant experimental nonhuman animals and are commonly studied under standard laboratory housing conditions. As housing conditions affect animals' physiology and behavior, this study investigated the effects of indoor and outdoor housing conditions on body weight and...

  6. Animal welfare - scientific approaches to the issues

    Contributor(s):: Millman, S. T.

    Nonhuman animal welfare is of significant public interest, globally and within the United States. Value-based judgments are intrinsic to animal welfare assessment, according to the relative weighting of factors associated with animal performance, health, affective states, and natural living. The...

  7. Handling, electric goad, and head restraint: effects on calves' behavior

    Contributor(s):: Goonewardene, L. A., Price, M. A., Stookey, J. M., Day, P. A., Minchau, G.

    96 weaned calves (48 bulls and 48 heifers) were allocated in a 2 x 2 x 2 arrangement to 3 treatments each with 2 levels: calves handled every 10 days or 20 days; an electric goad used or not used; and head gate restrained or not restrained. Behaviour responses were measured by 5 incremental...

  8. Portrayals of canine obesity in English-language newspapers and in leading veterinary journals, 2000-2009: implications for animal welfare organizations and veterinarians as public educators

    Contributor(s):: Degeling, C., Rock, M., Teows, L.

    In industrialized societies, more than 1 in 3 dogs and people currently qualify as overweight or obese. Experts in public health expect both these figures to rise. Although clinical treatment remains important, so are public perceptions and social norms. This article presents a thematic analysis...

  9. Dairy calves' adaptation to group housing with automated feeders

    Contributor(s):: Fujiwara, M., Rushen, J., Passille, A. M. de

    Group housing of dairy calves with automated milk feeders has likely welfare and labour saving advantages but delays in the calves adapting to the feeding system may reduce these advantages. We examined factors that influence calves' adaptation to the feeders. In Exp. 1, 77 Holstein calves were...

  10. Effects of pre-transport nutrient supplementation and transport duration on the post-transport blood biochemistry, bodyweight and welfare of ostriches

    Contributor(s):: Bejaei, M., Bennett, D. C., Schaefer, A. L., Cheng, K. M.

    There are very few abattoirs in North America that process ostriches ( Struthio camelus) which means producers are forced to transport their birds over long distances (>500 km) for processing. The objectives of this research were to investigate the effects of pre-transport nutrient...

  11. Short-term welfare implications of capture-mark-recapture trapping of medium-sized mammals: the brushtail possum ( Trichosurus vulpecula) as a case study

    Contributor(s):: Cowan, P., Forrester, G., Warburton, B.

  12. Shrink and mortality of beef cattle during long distance transportation

    Contributor(s):: Teke, B.

  13. Comparison of nicarbazin absorption in chickens, mallards, and Canada geese

    Contributor(s):: C. A. Yoder, L. A. Miller, K. S. Bynum

    Nicarbazin (NCZ), a coccidiostat commonly used in the poultry industry, causes reduced hatchability and egg quality in layer hens at a concentration of 125 ppm (8.4 mg/kg) in the feed. Although this effect is undesirable in the poultry industry, NCZ could provide a useful wildlife contraception...

  14. Alternative housing systems for fattening bulls under Austrian conditions with special respect to rubberised slatted floors

    Contributor(s):: Rouha-Muelleder, C., Absmanner, E., Kahrer, E., Zeiner, H., Scharl, T., Leisch, F., Stanek, C., Troxler, J.

  15. Development of a decision support system for assessing farm animal welfare in relation to husbandry systems: strategy and prototype

    Contributor(s):: Bracke, M. B. M., Metz, J. H. M., Dijkhuizen, A. A., Spruijt, B. M.

    Due to increasing empirical information on farm animal welfare since the 1960s, the prospects for sound decision-making concerning welfare have improved. This paper describes a strategy to develop a decision-making aid, a decision support system, for assessment of farm animal welfare based on...

  16. Alternative housing for sows and litters 1. Effects of sow-controlled housing on responses to weaning

    Contributor(s):: Pajor, E. A., Weary, D. M., Fraser, D., Kramer, D. L.

    A sow-controlled housing system and its affects on production and welfare problems resulting from the abrupt separation of piglets from sows at weaning was investigated. 44 sows and litters were housed during lactation in either a 'confined' pen where the sow and litter were kept together, or a...

  17. Influence of artificial vs. mother-bonded rearing on sucking behaviour, health and weight gain in calves

    Contributor(s):: Roth, B. A., Barth, K., Gygax, L., Hillmann, E.

    In artificial rearing, calves are often fed via an automatic milk feeder and have no opportunity to perform natural sucking behaviour. The majority of these calves show abnormal oral behaviours (e.g. cross-sucking). Furthermore, diseases are also a main problem in artificial rearing of calves,...

  18. Preference testing in intensively kept meat production rabbits for straw on wire grid floor

    Contributor(s):: Morisse, J. P., Boilletot, E., Martrenchar, A.

    384 hybrid commercial breed rabbits were assigned to 16 pens of 1.6 msuperscript 2 (15 rabbits/msuperscript 2). Eight pens used as controls had an all-wire floor, while in 8 other pens, rabbits could choose between a wire floor or a deep litter topped up once a week and completely replaced once...

  19. The relationship between farmers' attitude and behaviour towards calves, and productivity of veal units

    Contributor(s):: Lensink, J., Boissy, A., Veissier, I.

    Although veal production is highly standardized, there still remains variability in productivity between farms, which might be due to the farmers' behaviour towards their animals, which in turn depends on their attitude towards animals. 50 affiliated with the same veal company were studied. The...

  20. Crushing of piglets by sows: effects of litter features, pen features and sow behaviour

    Contributor(s):: Weary, D. M., Phillips, P. A., Pajor, E. A., Fraser, D., Thompson, B. K.
