The Effect of an Irregular Feeding Schedule on Equine Behavior
Contributor(s):: Zupan, Manja, Štuhec, Ivan, Jordan, Dušanka
We used eight horses 1 to 12 years old to investigate the influence of irregular feeding times on the behavior. The animals were housed in individual boxes, fed with hay ad libitum and barley-oat mixture at three set times; 05:00 (earlier feeding) on Thursdays, 07:00 (delayed feeding) on...
Short- and long-term effects of eight enrichment materials on the behaviour of finishing pigs fed ad libitum or restrictively
Contributor(s):: Zwicker, Bettina, Gygax, Lorenz, Wechsler, Beat, Weber, Roland
In a semi-natural environment, a lot of the daily activity of pigs is spent in exploratory and foraging behaviour. Providing enrichment material attractive to the pigs both over the short and long term is therefore important in intensive housing systems. This study aimed to investigate the effect...
Effect of social feeding environment on the feeding behaviour of dairy cows and their willingness to consume a novel feed
Contributor(s):: Mainardes, G. A., DeVries, T. J.
Dairy cows are often exposed to novel situations and may show a strong behavioural response to novel feeds. To test the impact of social contact while feeding and the reaction of mature cows towards a novel feed we compared: 1) animals fed individually and 2) cows fed socially (in pairs). It was...
Dietary diversity affects feeding behaviour of suckling piglets
Contributor(s):: Middelkoop, Anouschka, Choudhury, Raka, Gerrits, Walter J. J., Kemp, Bas, Kleerebezem, Michiel, Bolhuis, J. Elizabeth
Stimulating solid feed intake in suckling piglets is important to facilitate the weaning transition, exemplified by the positive correlation between pre- and post-weaning feed intake. The present study compared the effect of dietary diversity (i.e. offering two feeds simultaneously) and flavour...
"Who's been a good dog?" - Owner perceptions and motivations for treat giving
Contributor(s):: White, G. A., Ward, L., Pink, C., Craigon, J., Millar, K. M.
Complex relationships commonly exist between owners and their companion animals, particularly around feeding behaviour with an owner's affection or love for their animal most pronounced through the provision of food. It is notable that the pet food market is experiencing strong year-on-year...
Behavioral changes and feathering score in heat stressed broiler chickens fed diets containing different levels of propolis
Contributor(s):: Mahmoud, U. T., Abdel-Rahman, M. A. M., Darwish, M. H. A., Applegate, T. J., Cheng, H.
This experiment was conducted to evaluate the effects of dietary supplementation of green Brazilian propolis on behavioral patterns and feather condition of heat stressed broiler chickens. Five hundred and four (504) male Ross 708 broiler chicks at 15-day old were randomly allotted to six dietary...
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...
Aggressive behavior in two different group-housing systems for pregnant sows
Contributor(s):: Chapinal, N., Ruiz-de-la-Torre, J. L., Cerisuelo, A., Gasa, J., Baucells, M. D., Manteca, X.
The study housed 120 pregnant sows from Day 29 of pregnancy to 1 week before parturition either in groups of 10 with trickle feeding (TRICKLE) or in groups of 20 with an unprotected electronic sow feeding (FITMIX). The study recorded aggressive interaction on 11 nonconsecutive days. Frequency of...
Dairy cow behavior and welfare implications of time waiting before entry into the milking parlor
Contributor(s):: Dijkstra, C., Veermae, I., Praks, J., Poikalainen, V., Arney, D. R.
The objective of this study was to investigate dairy cows' time spent in the possibly stressful waiting area (WA) of the milking parlor (MP) and their behavioral patterns while there and thereby investigate comparative effects on their welfare. The experiments were carried out in 3 loose-housing...
Dog obesity: can dog caregivers' (owners') feeding and exercise intentions and behaviors be predicted from attitudes?
Contributor(s):: Rohlf, V. I., Toukhsati, S., Coleman, G. J., Bennett, P. C.
Dog obesity is a common nutritional disorder affecting up to 40% of the companion animal (pet) dog population in Australia and other developed nations. A clear understanding of factors determining relevant caregiver (owner) behaviors underpins effective treatment for this disorder. The theory of...
Positive reinforcement training as a technique to alter nonhuman primate behavior: quantitative assessments of effectiveness. (Training Nonhuman Primates Using Positive Reinforcement Techniques)
Contributor(s):: Schapiro, S. J., Bloomsmith, M. A., Laule, G. E.
Many suggest that operant conditioning techniques can be applied successfully to improve the behavioral management of nonhuman primates in research settings. However, relatively little empirical data exist to support this claim. This article is a review of several studies that discussed applied...

Increased number of whistles of bottlenose dolphins, Tursiops truncatus , arising from interaction with people
Contributor(s):: Akiyama, J., Ohta, M.
The acoustic mode is the most reasonable means for social animals such as dolphins to maintain contact in the underwater habitat, and has been developed since they moved to the sea. This study investigates variations in dolphin vocalizations under the following conditions in a captive...
Allogrooming in cattle: relationships between social preferences, feeding displacements and social dominance
Contributor(s):: Val-Laillet, D., Guesdon, V., Keyserlingk, M. A. G. von, Passille, A. M. de, Rushen, J.
The aim of this study was to describe the allogrooming behaviour of group-housed lactating cows (Bos taurus) as it relates to social dominance, friendship, parity and level of feeding competition. We measured the socio-negative (displacements at the feeder and in the lying stalls) and...
Choice of scan-sampling intervals - an example with quantifying neighbours in dairy cows
Contributor(s):: Neisen, G., Wechsler, B., Gygax, L.
To date, only a few studies using scan-sampling intervals to record neighbours in groups of animals explain how the interval length was chosen. In this study, we investigated the effects of different scan-sampling intervals, behavioural context, and the definition of neighbours on the accuracy of...
Claw removal and feeding ability in the edible crab, Cancer pagurus : implications for fishery practice
Contributor(s):: Patterson, L., Dick, J. T. A., Elwood, R. W.
Feeding ability and motivation were assessed in the edible crab, Cancer pagurus, to investigate how the fishery practice of de-clawing may affect live crabs returned to the sea. Crabs were either induced to autotomise one claw, or were only handled, before they were offered food. Initially,...
