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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
Positive reinforcement training for a trunk wash in Nepal's working elephants: demonstrating alternatives to traditional elephant training techniques
Contributor(s):: Fagen, A., Narayan, Acharya, Kaufman, G. E.
Many trainers of animals in the zoo now rely on positive reinforcement training to teach animals to voluntarily participate in husbandry and veterinary procedures in an effort to improve behavioral reliability, captive management, and welfare. However, captive elephant handlers in Nepal still...
Producer or purchaser: different expectations may lead to equine wastage and welfare concerns. (Special Issue: Equitation science.)
Contributor(s):: Hennessy, K. D., Quinn, K. M., Murphy, J.
Horses are individual, each having differential characteristics such as height, colour, breeding, conformation, and temperament. These bio-characteristics often influence potential purchasers when buying horses. This study sought to investigate if producers and potential purchasers placed similar...
Nutrition for working and service dogs
Contributor(s):: Wakshlag, J., Shmalberg, J.
Conformation, genetics, and behavioral drive are the major determinants of success in canine athletes, although controllable variables, such as training and nutrition, play an important role. The scope and breadth of canine athletic events has expanded dramatically in the past 30 years, but with...
An exploratory study on the effects of a straw dispenser in farrowing crates
Contributor(s):: Bulens, A., Renders, L., Beirendonck, S. van, Thielen, J. van, Driessen, B.
The effect of a straw dispenser in farrowing crates was investigated to determine the extent to which the provision of small quantities of straw has an influence on both sows and piglets. Sows and suckling piglets are often housed in barren environments with limited opportunities to show behavior...
Importance of personality traits in horses to breeders and riders
Contributor(s):: Graf, P., Borstel, U. K. von, Gauly, M.
Especially in horses, personality traits play an important role because horses' behavior influences their quality as a riding partner. In contrast to that, no objective assessment of horses' personality traits is available at present. Although initial efforts are made in this field, a successful...
Status quo of the personality trait evaluation in horse breeding: judges' assessment of the situation and strategies for improvement
Contributor(s):: Borstel, U. K. von, Pasing, S., Gauly, M., Christmann, L.
Recently, concerns about the validity of the evaluation of personality traits in horse breeding have been raised. For that reason, the aim of the present study was to assess the current status of personality trait evaluation in horse breeding. A survey was conducted among all station performance...
The relationship between responsiveness of first-lactation heifers to humans and the behavioral response to milking and milk production measures
Contributor(s):: Sutherland, M. A., Dowling, S. K.
The human-animal relationship can influence how an animal responds to situations involving humans and affect animal well-being and production. The objectives of this research were to (1) determine if there is a relationship between the behavioral reactivity of New Zealand dairy heifers toward...
