Abstract
The effects of movement of 12 milking cows from stanchion barn to free stall barn on performance of cow and milking work were studied.
1) After one month of movement, body weights of cows retuned to the level of 2 month before. But it took for 2 month for the recovery of milk yield.
2) The somatic cell counts (SCC) were quickly increased soon after movement. After 2 month, SCC returned to the level before movement.
3) After movement, frequencies of excretion faeces and urine in milking parlour increased remarkably, and after one month they became similar as before. The number of cow, which showed the reluxed figure with her head up during milking, reached 9 per 13 after 1.5 months, and this correspounded to the decrease of frequencies of excretion. Naildisease were decreased after 2 month.
4) It took 2 week that both milking cows and workers to be accustomed to milking parlour system.
From these resulrs, it seems that the effects of movement of milking cows on milking work remained for 2 week, but productive response remainded for 2 month.
