Dustbathing is one of the major behavioural systems of domestic fowl that is constrained by commercial caging systems. Although research conducted over the last 20 years has revealed a great deal about causation of dustbathing, attempts at ...
Time-dependent transition probabilities and the assessment of seasonal effects on within-day variations in chewing behaviour of housed sheep [0.03%]

State transitions in the chewing behaviour of six half-breed (Île de FrancexTexel) yearling female sheep (Ovis aries L.) were studied by using jaw movements recorded continuously over 5 days at the end of a number of experimental periods f...
The social environment influences the behavioural responses of beef cattle to handling [0.03%]
社会环境影响牛肉 cattle 对处理的行为反应

L Grignard et al.
In cattle, a gregarious species, the social group influences individual stress responses to fear-eliciting situations. As handling can be stressful for farm animals, it can be hypothesised that social partners modify individual responses to...
A note on possible link between behaviour and the occurrence of lameness in dairy cows [0.03%]

Lameness in cattle is a major welfare problem and has important economic implications. It is known that lameness has a multifactorial causation; however, it is still not clear why some individuals are more susceptible than others to present...
The interaction of liveweight and the degree of competition on drinking behaviour in growing pigs at different group sizes [0.03%]
不同群大小下生长育肥猪活重和竞争强度对饮水行为的影响

SP Turner
The pattern of drinking behaviour in pigs, and the influence of social factors such as competition on this behaviour, have been poorly documented. If competition for access to a limited resource is substantial, access to that resource may b...
Space use and agonistic behaviour in relation to sex composition in large flocks of laying hens [0.03%]
母鸡群的空间利用及争斗行为与其性别构成的关系研究

Some authors have found indications of subgroup formation when domestic fowl are forced to live together in large flocks, while others have not. In this study experiments were carried out to test the hypothesis that hens in large flocks hav...
The effect of exposure to oestrous ewes on rams' sexual behaviour, plasma testosterone concentration and ability to stimulate ovulation in seasonally anoestrous ewes [0.03%]
公羊接触发情母绵羊后性行为、血浆睾丸酮浓度及刺激绝情期绵羊排卵能力的变化
HJ Rosa,DT Juniper,MJ Bryant
HJ Rosa
Previous research has shown that the proportion of seasonal anoestrous ewes that ovulate in response to the introduction of rams ('ram effect') is dependent upon pheromonal and sexual behavioural stimuli emitted by the rams. Close contact w...
The effect of omitted milking on the behaviour of cows in the context of cluster attachment failure during automatic milking [0.03%]
挤奶遗漏对自动挤奶失败情况下奶牛集群连接行为的影响
J Stefanowska,M Plavsic,AH Ipema et al.
J Stefanowska et al.
In robotic milking there is always a slight chance of failure to attach the milking cluster. Attachment failure is most likely for cows whose udder conformation is less convenient for robot attachment. In general, after milking failure cows...
