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...
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...
Agonistic behaviour, skin lesions and activity pattern of entire male, female and castrated male finishing pigs
Contributor(s):: Bunger, B., Schrader, L., Schrade, H., Zacharias, B.
Fattening of intact boars is the least invasive alternative to the detrimental welfare effects of surgical castration of piglets. However, beside problems such as boar taint the divergent agonistic and sexual behaviour of boars may impair the pigs' welfare during fattening. To evaluate the effect...
Conformation analysis of horses used in equine-assisted activities at Polish hippotherapeutic centers
Contributor(s):: Lojek, J., Pluta, M., Ciesla, A., Domachowska, A., Przybylowicz, N., Lojek, A.
The objective of the research was to determine the basic conformation traits of horses of different breeds performing hippotherapeutic service at chosen equine therapy centers. The research material included a total of 47 horses from 9 centers: Warsaw (7 horses), Bydgoszcz (6), Lublin and the...
Breed characteristics of abandoned and lost dogs in the Czech Republic
Contributor(s):: Voslarova, E., Zak, J., Vecerek, V., Bedanova, I.
Records on sheltered dogs were collected from 3 municipal dog shelters situated in different regions of the Czech Republic from 2010 to 2013. A total of 3,875 dogs were analyzed in this study. Among these, 1,614 dogs were subsequently reclaimed (lost dogs) and 2,261 dogs were abandoned and...
Acoustic analysis of cattle ( Bos taurus) mother-offspring contact calls from a source-filter theory perspective
Contributor(s):: Torre, M. P. de la, Briefer, E. F., Reader, T., McElligott, A. G.
Cattle vocalisations have been proposed as potential indicators of animal welfare. However, very few studies have investigated the acoustic structure and information encoded in these vocalisations using advanced analysis techniques. Vocalisations play key roles in a wide range of communication...
Comparison of the effects of weaning and castration when conducted separately or in combination on the behaviour of crossbred beef cattle
Contributor(s):: Lambertz, C., Farke-Rover, A., Moors, E., Gauly, M.
The objective of the present study was to evaluate the behavioural effects of Burdizzo castration of crossbred beef calves when weaned and castrated separately (castrated 8 weeks after weaning) or in combination. Over two consecutive years a total of 111 Limousin * Simmental male calves were...
Effects of growth-promoting technology on feedlot cattle behavior in the 21 days before slaughter
Contributor(s):: Stackhouse-Lawson, K. R., Tucker, C. B., Calvo-Lorenzo, M. S., Mitloehner, F. M.
There is growing interest in the animal welfare implications of growth-promoting technology used in feedlot cattle, namely hormonal implants, ionophores, antibiotics and β 2-adrenergic agonists. Previous studies have focused on the effects of implants on aggression, but little work has...
Fresh wood reduces tail and ear biting and increases exploratory behaviour in finishing pigs
Contributor(s):: Telkanranta, H., Bracke, M. B. M., Valros, A.
Chewing and rooting are high behavioural priorities in pigs. Lack of suitable materials can lead to abnormal behaviours such as tail and ear biting. In commercial farming, slatted floors limit the use of straw, and various point-source objects have therefore been developed. The crucial challenge...
Variations in the timing of reinforcement as a training technique for foals ( Equus caballus )
Contributor(s):: Warren-Smith, A. K., McLean, A. N., Nicol, H. I., McGreevy, P. D.
Horses are used worldwide for a range of activities. Their usefulness and welfare in these pursuits are strongly influenced by their trainability, which may in turn be influenced by learning ability. Handling and riding horses can expose both handler and horse to a considerable risk of injury....
Genetic analysis of the individual pig behaviour in backtests and human approach tests
Contributor(s):: Scheffler, K., Stamer, E., Traulsen, I., Krieter, J.
The most recent development in pig production has focused increasingly on the well-being of the individual pig and animal-friendly housing conditions, i.e. the launch of the group housing of sows in the EU. In this regard, however, standard procedures which may be stressful to the animals and...
Differences in open field behavior between heterozygous and homozygous negative gilts for the RYR(1) gene
Contributor(s):: Fabrega, E., Diestre, A., Font, J., Carrion, D., Velarde, A., Ruiz-de-la-Torre, J. L., Manteca, X.
A test widely used to assess fear and novelty responses in domestic species is the open field. The aim of this study was to investigate the effect of RYR(1) genotype on open field behavior in growing pigs. The study subjected 15 heterozygous (Nn) and 15 RYR(1)-free (NN) gilts of 19 weeks of age...
Human interaction as environmental enrichment for pair-housed wolves and wolf-dog crosses
Contributor(s):: Mehrkam, L. R., Verdi, N. T., Wynne, C. D. L.
Private nonhuman animal sanctuaries are often financially limited in their ability to implement traditional environmental enrichment strategies. One possible solution may be to provide socialized animals with human interaction sessions. However, the merit of human interaction as enrichment has...
Effects of stocking rate on measures of efficacy and welfare during carbon dioxide gas euthanasia of young pigs
Contributor(s):: Fiedler, K. J., Parsons, R. L., Sadler, L. J., Millman, S. T.
The objective of this study was to evaluate the effects of chamber stocking rate on facets of animal welfare and efficacy during gas euthanasia of young pigs ( Sus scrofa domesticus). Crossbred pigs (390 neonatal and 270 weaned) designated for euthanasia at production farms were randomly assigned...
The effect of breed on age-related changes in behavior and disease prevalence in cognitively normal older community dogs, Canis lupus familiaris
Contributor(s):: Salvin, H. E., McGreevy, P. D., Sachdev, P. S., Valenzuela, M. J.
Variation in breed longevity in the dog has led to the inference that large dogs age at a faster rate than small dogs, possibly because of an increased oxidative load. Potential differences in behavioral aging (the rate of age-related decline in cognito-behavioral performance) across breeds...
