  1. Associations between milk intake and activity in the first days of a calf's life and later growth and health

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

    We examined whether calves' milk intake and activity in the days after birth predict later growth and the risk of illness. Female Holstein calves ( n=130) were housed in individual pens where they were allowed ad libitum milk from birth to 5 days of age. Daily milk intakes were recorded and...

  2. The effect of lying motivation on cow behaviour

    Contributor(s):: Norring, M., Valros, A.

    Cows in dairy barns spend time standing while waiting for milking, accessing feed and entering the resting area. It has been suggested that high yielding cows may represent a trade off situation regarding eating and lying particularly in systems where there is a long waiting period before...

    Contributor(s):: Bulens, A., Beirendonck, S. van, Thielen, J. van, Buys, N., Driessen, B.

    This study verified the effect of straw blocks on the behavior and growth of finishing pigs and possible interactions with the genetic background (boar type). A total of 359 finishing pigs, which were offspring from different boar types, were housed in gender-mixed pens with slatted floors. Half...

  4. Genetic study of stress assessed with infrared thermography during dressage competitions in the Pura Raza Espanol horse

    Contributor(s):: Sanchez, M. J., Bartolome, E., Valera, M.

    Despite the fact that physiological parameters in dressage are important because of their close connection to human-horse accidents, performance and welfare, these parameters are only rarely included in horse breeding programs. In Spain, the Pura Raza Espanol horse (PRE) Breeding Program focuses...

  5. Welfare outcomes for 3- and 6-month-old beef calves in a tropical environment castrated surgically or by applying rubber rings

    Contributor(s):: Petherick, J. C., Small, A. H., Reid, D. J., Colditz, I. G., Ferguson, D. M.

    Castration of cattle using rubber rings is becoming increasingly popular due to the perceived ease of the procedure and greater operator safety when compared with surgical castration. Few comparative studies have investigated the effects of different castration methods and calf age on welfare...

  6. 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...

  7. How to train a dog to detect cows in heat-training and success

    Contributor(s):: Johnen, D., Heuwieser, W., Fischer-Tenhagen, C.

    Efficient and accurate estrus detection is a key management factor determining acceptable reproductive performance in dairy herds. Previous studies have shown that dogs can differentiate between vaginal mucus samples of cows in estrus and vaginal mucus samples of cows in diestrus with an accuracy...

  8. Mate choice, maternal investment and implications for ostrich welfare in a farming environment

    Contributor(s):: Bonato, M., Cherry, M. I., Cloete, S. W. P.

    At present, the ostrich industry is inefficient, on account of being characterised by inadequate egg production, high embryo mortality, poor chick survival and suboptimal growth rates. However, as ostrich farming commenced only in the mid 19th century in South Africa, farmed ostriches have had a...

  9. Behaviour of pre-pubertal gilts and its relationship to farrowing behaviour in conventional farrowing crates and loose-housed pens

    Contributor(s):: Ison, S. H., Wood, C. M., Baxter, E. M.

    Individual variation in the reproductive performance of sows has the potential for greater negative impacts in loose-farrowing systems. Therefore, the ability to select gilts that will perform well would be a major advantage. This study investigated the behaviour of gilts during pre-pubertal...

  10. Slow and steady wins the race? No signs of reduced welfare in smaller broiler breeder hens at four weeks of age

    Contributor(s):: Lindholm, C., Calais, A., Jonsson, J., Yngwe, N., Berndtson, E., Hult, E., Altimiras, J.

    Broiler breeder chickens are commonly reared under strict feed-restriction regimes to reduce obesity-induced health and fertility problems during adult life, and are assumed to experience a reduced welfare due to the resulting hunger. In these conditions, feed competition could influence the...

  11. Achieving optimum performance in a loose-housed farrowing system for sows: the effects of space and temperature

    Contributor(s):: Baxter, E. M., Adeleye, O. O., Jack, M. C., Farish, M., Ison, S. H., Edwards, S. A.

    Piglet survival relies on interactive influences of the sow, her piglets and their environment. There are a number of design challenges in a loose-housed farrowing and lactation system to optimise this dynamic, including achieving farrowing in the desired location (i.e. a protected nest area) and...

  12. 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...

  13. Effects of stage of gestation at mixing on aggression, injuries and stress in sows

    Contributor(s):: Stevens, B., Karlen, G. M., Morrison, R., Gonyou, H. W., Butler, K. L., Kerswell, K. J., Hemsworth, P. H.

    Confinement of breeding sows to stalls is a controversial welfare issue, and there is a worldwide move to house gestating sows in groups. We examined the effects of day of mixing following insemination on aggression, injuries and stress in sows. A total of 800 sows were used in this experiment...

  14. Group composition for fattening entire male pigs under enriched housing conditions - influences on behaviour, injuries and boar taint compounds

    Contributor(s):: Holinger, M., Fruh, B., Hillmann, E.

    In organic farming, the production of pork from entire male pigs seems to be the most promising alternative to castration, as organic animal husbandry aims at high standards of animal welfare and elimination of mutilations. However, previous research on behaviour of entire male pigs was mostly...
