The av. milk yield and incidence of flinching, kicking and stepping during teatcup placement and removal (FSK response) were both higher among 10 randomly selected Friesian X Jersey cows in periods of 5 and 4 days when they were milked by one herdsman than in 5 days when they were milked by another (P less than 0.001). A positive relationship between FSK response and milk yield (P less than 0.05) was established over 9 milkings for 1 newly-calved cow conditioned to increase or decrease milk yield in response to a visual stimulus. ADDITIONAL ABSTRACT: Short-term increases in the milk yield of lactating dairy cows were associated with increases in the occurrence of flinching, stepping and kicking which occurred during machine milking. Since the nature of the observed relationship between increased objectionable behaviours during milking and milk yield is unknown, culling dairy cows for behaviour during milking as the sole criterion may not be economically justifiable.
