    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...

  2. Effects of different dietary protein levels during rearing and different dietary energy levels during lay on behaviour and feather cover in broiler breeder females

    Contributor(s):: Emous, R. A. van, Kwakkel, R., Krimpen, M. van, Hendriks, W.

    An experiment was conducted to determine the effects of different dietary protein levels during rearing and different dietary energy levels during lay on behaviour and feather cover in broiler breeder females. A 2*3*2 factorial arrangement of treatments was used. A total of 2880 Ross 308...

  3. 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...

  4. 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...

  5. 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...

  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. 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...

  8. 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...

  9. Effects of food structure and nutritional quality and animal nutritional state on intake behaviour and food preferences of sheep

    | Contributor(s):: Villalba, J. J., Provenza, F. D.

    There is evidence of the independent effects of plant physical and chemical characteristics on foraging, but little has been done to determine how these traits interact to affect food selection. The effect of the nutritional state of lambs on intake behaviour and preference for feeds with...

  10. Influence of post-calving regrouping strategy on welfare and performance parameters in dairy heifers

    | Contributor(s):: O'Connell, N. E., Wicks, H. C. F., Carson, A. F., McCoy, M. A.

    Thirty-six Holstein Friesian heifers (dairy herd replacements) were assigned to one of three regrouping treatments during the post-calving period. In Treatment 1, heifers were introduced individually to an established group of cows and heifers within 24 h of calving ('Single - day 1'). In...

  11. Lambs fed protein or energy imbalanced diets forage in locations and on foods that rectify imbalances

    | Contributor(s):: Scott, L. L., Provenza, F. D.

    Ruminants eat a variety of foods from different locations in the environment. While water, cover, social interactions, and predators are all likely to influence choice of foraging location, differences in macronutrient content among forages may also cause ruminants to forage in different...

  12. Some aspects of milk that elicit non-nutritive sucking in the calf

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

    Male Holstein dairy calves were allowed to suck a non-nutritive teat after meals of either cow milk or milk replacer, and the amount of non-nutritive sucking that occurred during the 10 min following the meal was observed. There were no differences between milk and commercial milk replacer in the...

  13. Trainability of eliminative behaviour in dairy heifers using a secondary reinforcer

    | Contributor(s):: Whistance, L. K., Sinclair, L. A., Arney, D. R., Phillips, C. J. C.

    Soiled bedding influences cleanliness and disease levels in dairy cows and there is no evidence of an inherent latrine behaviour in cattle. If cows were trained to use a concrete area of the housing system as a latrine, a cleaner bed could be maintained. Thirteen group-housed, 14-16-month-old...

  14. Effect of different free stall surfaces on behavioural, productive and metabolic parameters in dairy cows

    | Contributor(s):: Calamari, L., Calegari, F., Stefanini, L.

    Two experiments were carried out on 56 lactating dairy cows in an experimental free stall barn comparing four different lying surfaces: straw bedded pack (ST), rubber mat (RM), mattress (MA) and sand (SA). In the first experiment (26 days) cows were allowed to choose between free stalls with each...

  15. Feeding small quantities of grain in the parlour facilitates pre-milking handling of dairy cows: a note

    | Contributor(s):: Ceballos, A., Weary, D. M.

    Food rewards are increasingly recognized as a method of training animals to submit to management procedures that might otherwise require aversive handling. The aim of the current study was to determine if feeding small amounts of concentrate in the parlour could improve entrance behaviour. Cows...

  16. Landscape nutritional patterns and cattle distribution in rangeland pastures

    | Contributor(s):: Ganskopp, D. C., Bohnert, D. W.

    On rangelands, uneven or unmanaged livestock distribution can adversely affect plant community composition, riparian function, or displace wildlife. These issues have historic precedents and are still a challenge for those managing rangelands. A thorough understanding of the mechanisms governing...

  17. Relationship between some chemical components of herbage, dietary preference and fresh herbage intake rate by the Japanese serow

    | Contributor(s):: Deguchi, Y., Sato, S., Sugawara, K.

    The serow is a native Japanese mammal and has been designated as a special natural treasure in Japan. However, it has been a pest of crops since the 1970s. Since the serow is an indigenous and protected species, it must be controlled without endangering the animal itself. To do this, it is...

  18. The influence of acidosis and live yeast ( Saccharomyces cerevisiae ) supplementation on time-budget and feeding behaviour of dairy goats receiving two diets of differing concentrate proportion

    | Contributor(s):: Desnoyers, M., Giger-Reverdin, S., Sauvant, D., Bertin, G., Duvaux-Ponter, C.

    Increasing the percentage of concentrate in the diet can influence feeding behaviour of ruminants. It can also lead to subacute rumen acidosis and the addition of yeast to the rumen ecosystem might influence fermentation and subsequently help the ecosystem deal with the consequences of high...

  19. Relationships between human-animal interactions and productivity of commercial dairy cows

    | Contributor(s):: Hemsworth, P. H., Coleman, G. J., Barnett, J. L., Borg, S.

    This study examined the relationships between a number of stockperson and cow variables at 66 commercial dairy farms in Victoria, Australia over a 2-year period (1995-1997). Variables such as the attitudes and behaviour of stockpeople toward their cows and the behavioural response to humans and...

  20. The sexual behaviour of experimentally underfed bulls

    | Contributor(s):: Wierzbowski, S.

    Bulls (18 months old) from each of eight pairs of twins were divided into two groups which were fed a diet containing either 700 g (controls) or 500 g (experimental) crude protein. Sexual behaviour and semen columes were noted every two months until the bulls were five years old. At five years...
