  1. A combination of behavioral and physiological indicators for assessing pig welfare on the farm

    Contributor(s):: Candiani, D., Salamano, G., Mellia, E., Doglione, L., Bruno, R., Toussaint, M., Gruys, E.

    The purpose of this research was to identify pig welfare indicators that could help in recognizing stressful practices on farm. The study evaluated behavioral and physiological indicators (cortisol and negative acute phase proteins) in 2 groups of 20 female pigs 4 months old after a 48-hr...

  2. A note on the cecotrophy behavior in capybara ( Hydrochaeris hydrochaeris )

    Contributor(s):: Mendes, A., Nogueira, S. S. da C., Lavorenti, A., Nogueira-Filho, S. L. G.

    Six adult capybaras (56 kg) were placed in individual pens and observed for 96 serial hours. During this period a behavioural pattern believed to consist of caecotrophy was observed 243 times. Animals sat on their hind limbs, stretched either limb out, bent over driving their heads in the...

  3. A note on the effects of a commercial tryptophan product on horse reactivity

    Contributor(s):: Malmkvist, J., Christensen, J. W.

    Tryptophan supplements are marketed worldwide as calmatives for fearful or excitable horses, although there are no scientific publications that support the efficiency of tryptophan on horses. Here, we investigate whether a commercial feed additive with tryptophan reduces the reactions of horses...

  4. A note on yearling horse ingestive and agonistic behaviours in three concentrate feeding systems

    Contributor(s):: Motch, S. M., Harpster, H. W., Ralston, S., Ostiguy, N., Diehl, N. K.

    The objective of this study was to compare behaviours of yearling horses fed concentrates under each of three management systems. Over two consecutive years, 16 yearling horses (n=8/year; 4 fillies, 4 geldings, full siblings between years) were observed over a 60-day trial period/year at 15:30 h...

  5. Allergen avoidance does not alter airborne cat allergen levels in classrooms

    Contributor(s):: Karlsson, A. S., Renström, A., Hedrén, M., Larsson, K.

  6. An investigation into the effect of different protein and energy intakes on model tail chewing behaviour of growing pigs

    Contributor(s):: McIntyre, J., Edwards, S. A.

    Twenty-four crossbred pigs were housed individually and allocated at 62 kg (S.E.M.=0.81) to one of three diets providing differing daily protein and energy intakes: control (C) 1.42 g CP/MJ DE, fed to provide 2.85 maintenance energy; low protein (LP) 0.76 g CP/MJ DE fed to provide the same daily...

  7. Assessment of welfare and productive performance in dairy cows organically reared in plains or hilly areas

    Contributor(s):: Martelli, G., Valla, H., Bucci, D., Zaghini, G., Vignola, G., Sardi, L.

    The aim of this study was to investigate several production parameters and the level of welfare of organic dairy cows kept in two different geographical and social contexts. The study group included 1,751 cows from 19 organic dairy farms, 11 of which were situated in hilly areas and 8 in plains...

  8. Behaviour and percentage eye-white in cows waiting to be fed concentrate - a brief report

    Contributor(s):: Sandem, A. I., Braastad, B. O., Bakken, M.

    A major task when developing methods of assessing animal welfare is to identify observable external indicators of internal subjective feelings. In this paper, we tested the hypothesis that the percentage of white in the eyes would change as a response to two emotional stimuli; waiting to be fed...

  9. Behaviour and welfare of veal calves fed different amounts of solid feed supplemented to a milk replacer ration adjusted for similar growth

    | Contributor(s):: Webb, L. E., Bokkers, E. A. M., Engel, B., Gerrits, W. J. J., Berends, H., Reenen, C. G. van

    Veal calves in Europe are typically fed large quantities of milk replacer and small amounts of solid feed, a diet known to lead to the development of abnormal oral behaviours in these animals. These abnormal oral behaviours are thought to be an indication of frustration, chronic stress, and...

  10. Behaviour of growing lambs housed on straw or woodchip bedding materials and their preference for floor type

    | Contributor(s):: Wolf, B. T., Molloy, H. R. B., Trayte, M. J., Rose, M. T.

    Straw is widely used as a bedding material for housed sheep, but alternatives are needed in regions where straw is expensive or in short supply. The aim of this work was to compare time budgets, growth and food intake of growing, finishing lambs housed on either woodchip or straw bedding...

  11. Behaviour of parturient Australian bush goats. I. Doe behaviour and kid vigour

    | Contributor(s):: Allan, C. J., Holst, P. J., Hinch, G. N.

    The behaviour of multiparous does around parturition and the subsequent vigour of the kids were observed in 153 Australian bush goats supplemented with 1 of 3 levels of protein at kidding. Supplementation commenced 142 days after introduction of entire bucks and continued for 17 days. Does kidded...

  12. Behavioural response of pure Ankole and crossbred (Ankole * Holstein) cows to seasonal pasture variations in south-western Uganda

    | Contributor(s):: Idibu, J., Kabi, F., Mpairwe, D.

    This study evaluated the effects of season and pasture species on variations in sward composition, pasture quantity (plant-height and biomass) and quality [crude protein (CP), neutral detergent fibre (NDF) and in vitro organic matter digestibility (IVOMD)]. Behavioural responses of a group of 10...

  13. Case control study on environmental, nutritional and management-based risk factors for tail-biting in long-tailed pigs

    | Contributor(s):: Kallio, P. A., Janczak, A. M., Valros, A. E., Edwards, S. A., Heinonen, M.

    | Contributor(s):: Czaja, Raymond, Wills, Abigail, Hanitriniaina, Sahondra, Reuter, Kim E., Sewall, Brent J.

    The domestic cat Felis catus has a long history of interaction with humans, and is found throughout the world as a household pet and a feral animal. Despite people's often sentimental association with cats, cat meat is sometimes consumed by them; this practice can have important implications for...

  17. Cow milk and human development and well-being

    | Contributor(s):: Maijala, K.

    This paper reviews the hypotheses of the relationship between milk and human coronary heart disease (CHD). These hypotheses are examined and their original historic deficiencies are discussed. This is followed by the new and emerging scientific evidence to support, question or refute these...

  18. Daily selection of feeding areas by cattle in homogeneous and heterogeneous environments

    | Contributor(s):: Bailey, D. W.

    Plots containing 3 heterogeneous patches that varied in forage quality and quantity, and plots containing 3 homogeneous patches were grazed by yearling steers in a 2-part study. During the 1st trial, steers selected patches from a central decision area, and fences divided the patches. During the...

  19. Diurnal rhythm of feather pecking behaviour and condition of integument in four strains of loose housed laying hens

    | Contributor(s):: Kjaer, J. B.

    2400 chickens from 4 commercial strains, Lohmann Selected Leghorn (LSL), Norbrid 41 (NB), Lohmann Brown (LB) and ISA Brown (ISA) were reared and kept in aviary systems. Feather pecking behaviour was recorded by time sampling from video recordings at 38 weeks of age and condition of plumage, keel...
