The psychological interaction between the stockman and his animals and its influence on performance of pigs and dairy cows.

The interaction between animals of economic importance and man, though considered important by many people, has been the subject of only limited investigation. Research on pigs and dairy cows is reported here. The research methodology for pigs is essentially one of controlled experiments, that for dairy cows one of field observations and participant action. The psychological traits of high achievement dairy cow stockmen are shown and discussed. The general conclusions from research with different species, indicate that pleasant, consistent and confident handling leads to a good relationship. There is evidence that this relationship can be correlated with higher performance of animals. The implications for the welfare of animals are considered.
