A cross-cultural comparison of reports by German Shepherd owners in Hungary and the United States of America
Contributor(s):: Wan, M., Kubinyi, E., Miklosi, A., Champagne, F.
Cross-cultural comparisons of dog behavior and dog-keeping practices are limited. The current study compared the questionnaire responses of German Shepherd owners in Hungary and the United States of America (USA). Owners provided information about their dog-keeping practices, as well as reports...
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...
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...
Influences of immunocontraception on time budgets, social behavior, and body condition in feral horses
Contributor(s):: Ransom, J. I., Cade, B. S., Hobbs, N. T.
Managers concerned with shrinking habitats and limited resources for wildlife seek effective tools for limiting population growth in some species. Fertility control is one such tool, yet little is known about its impacts on the behavioral ecology of wild, free-roaming animals. We investigated...
Observer ratings: validity and value as a tool for animal welfare research
Contributor(s):: Meagher, R. K.
Ratings by human observers have long been used by animal scientists and veterinarians to assess certain physical traits (e.g. body fat), and can also be applied to the assessment of behaviour and a variety of welfare-relevant variables (e.g. pain responsiveness, alopecia/barbering). Observer...
Social network analysis of behavioural interactions influencing fin damage development in Atlantic salmon ( Salmo salar ) during feed-restriction
Contributor(s):: Jones, H. A. C., Hansen, L. A., Noble, C., Damsgard, B., Broom, D. M., Pearce, G. P.
The role of behavioural interactions in the development of fin damage amongst Atlantic salmon (Salmo salar) undergoing feed-restriction was investigated using social network analysis. Dorsal fin damage, particularly erosion, was seen only in groups subjected to feed-restriction. The amount of...
Social status and physical condition of mother and sex ratio of offspring in cervids
Contributor(s):: Kojola, I.
The degree of polygyny and litter size varies between deer species and may affect the relationship between maternal condition and offspring sex ratio. The hypothesis that females in good condition produce more male offspring than females in poorer condition was investigated by analysing data from...
The effect of breed and housing system on dairy cow feeding and lying behaviour
Contributor(s):: O'Driscoll, K., Boyle, L., Hanlon, A.
In Ireland there is growing interest in managing dairy cows on out-wintering pads (OWPs) during the winter, as a low cost alternative to housing indoors. This study investigated feeding and lying behaviour of two breeds of dairy cow (Holstein-Friesian and Norwegian Red) at pasture (PAS) and in...
An evaluation of mattresses and mats in two dairy units
Contributor(s):: Chaplin, S. J., Tierney, G., Stockwell, C., Logue, D. N., Kelly, M.
In order to investigate the relative merits of mats and mattresses in terms of cow comfort, production and performance, 29 cows were housed on ethylethene vinyl acetate mats and 29 on mattresses of loose rubber crumb with a polypropylene cover, at each of 2 similar dairy units of the Scottish...
Assessing dominance in sheep in a competitive situation: level of motivation and test duration
Contributor(s):: Erhard, H. W., Fabrega, E., Stanworth, G., Elston, D. A.
The dominance structure in an established group of sheep is often difficult to determine in the field, because of the low frequency of agonistic interactions, often resulting in some pairs of animals not interacting at all in the observation period. A solution to this problem is to test each pair...
Differences in skeletal and ornamental traits between laying hen cannibals, victims and bystanders
Contributor(s):: Cloutier, S., Newberry, R. C.
The size of skeletal and ornamental traits, and asymmetries in bilateral skeletal traits, between victims of cannibalism, cannibals and bystanders within small groups of caged female White Leghorns at the time of cannibalistic attacks (i.e. injurious pecks resulting in bleeding) were compared. It...
Physiological and behavioural responses of cows from two beef breeds submitted to different suckling strategies
Contributor(s):: Alvarez-Rodriguez, J., Sanz, A.
This experiment was designed to study the effects of avoiding calf contact and genotype on the metabolic, behavioural and reproductive traits of beef cows during lactation. Fifty-two multiparous cows, 25 Parda de Montana (PA) and 27 Pirenaica (PI), fed at maintenance were assigned from the day...
