The micro pig’s (Sus scrofa) ability to use visual, olfactory and spatial cues to locate a food resource in a novel environment was investigated. In Experiment 1, four castrated male pigs were trained to identify a food resource—one of two plasti

An animat is either a computer simulated animal or a robot with behavior that can be experimentally manipulated and monitored. Thus, animats are useful in the development and testing of theoretical models. Animats have been used to study a variety of

A pen of 15 bulls and a pen of 15 steers were observed to investigate the relationship between dominance and eating behavior. The feeding system employed a stall attached to a feed hopper whereby only one animal of a pen could eat at one time. Eating

Two methods of observation of agonistic interactions were employed to determine if a short-cut method of dominance evaluation in cattle could be developed. The first method of observation involved the use of a dominance tube to test all combination-p

Thirty-two Holstein cows averaging 132 d postpartum were used in an 8-wk trial to test the effect of feed access time (8, 12, 16, or 20 h/d) on intake and milk production using diets containing either 40 or 60% corn silage. Increasing feed access fro

Groups of 15 feedlot beef cattle were fed from single stalls, whereby only one eating space was provided for each pen of animals. The eating behavior of the stall-fed groups was compared to that of trough-fed groups. The stall-fed cattle ate faster (
