Vocal communication in the domestic pig is generally not well documented. The aim of this experiment was to categorise and ascribe the function of the vocalisations of 67 Large WhitexLandrace gilts during a standard human approach test. At ...

Two breeds of dairy cattle, one selected for intra-specific fighting and dominance ability (Hérens, H), the other not selected for this behavioural trait (Brune des Alpes, BA), submitted to the same management techniques, were compared wit...

I studied the responses (retreats, threats, attacks or leaving the rookery) of South American fur seals Arctocephalus australis to tourist approaches at a non-reproductive, continental colony of located in Cabo Polonio, Uruguay (34 degrees ...
A note on using a laser-based technique for recording of behaviour and location of free-ranging animals [0.03%]

We developed a precise, remote (up to 300m) observation system to record animal location and behaviour that requires no animal handling or disruption of the normal environment. Our system, combining a survey laser and a laptop, also allows ...
The effects of operant control over food and light on the behaviour of domestic hens [0.03%]
操作性条件作用对家养母鸡行为的影响

In intensive farming systems, the animals have little control over important elements in their environments. For instance, food of a pre-set type is delivered at set times, and the lighting schedule is controlled by the farmer. It has been ...
Use of perches and nestboxes by laying hens in relation to social status, based on examination of consistency of ranking orders and frequency of interaction [0.03%]
栖位和巢盒的利用与鸡的社会地位有关——根据排序一致性和相互作用频率的研究结果得出的结论

L S. Cordiner
Four groups of 15-19 adult ISA Brown hens were studied in pens to assess the relationship between social status and use of perches and nestboxes. This was to test the hypothesis that subordinate hens use these resources more by day, for avo...
Influence of environmental temperature on PGF(2alpha)-induced nest building in female pigs [0.03%]

Domestic pigs build a maternal nest in the day preceding parturition. We have shown that prostaglandin F(2alpha) (PGF(2alpha)) induces nest building behaviour in non-pregnant pigs. The aim of this experiment was to examine the effects of di...
Seasonal changes in circadian grazing patterns of Kerry cows (Bos Taurus) in semi-feral conditions in Killarney National Park, Co. Kerry, Ireland [0.03%]

Domestic cattle generally graze during the day although some night-time grazing also occurs. However, questions remain as to the effect of management on circadian grazing patterns. This study provides for the first time a quantification of ...

L Grignard et al.
Beef cattle responses to handling depend partly on the genetic characteristics of the animals. However, the various methods used in order to assess these responses differ to a great extent. The purpose of this work is to study the relations...
Cognitive abilities - the result of selective pressures on food acquisition? [0.03%]
认知能力——择食压力的结果吗？
A N. McLean
A N. McLean
Locating and capturing food are suggested as significant selection pressures for the evolution of various cognitive abilities in mammals and birds. The hypothesis is proposed that aspects of food procuring behaviour should be strongly indic...
