摘要: Abstract One of the characteristics automatic milking is that cows can visit robot voluntarily. This induces a large variation in frequency visits to and, thus, results intervals. The relationships between interval, milk production and flow-rate using were studied with data from research farm (66 cows) collected October 1997 September 1999 (107 785 milkings). average interval was 9.2 h (S.D.=3.3). 2.5 kg/min (S.D.=0.79) 1.3 kg/h. There Respectively, 9.7 17.6 percent milkings had an shorter than 6 or longer 12 h. In this variation, cow factors do play role. Of all cows, 6% less twice per day. Cow time day contributed interval. addition factors, length significant effect on flow-rate. effects hour greater for higher producing lower cows. could be part explanation apparent increase SCC milking. Optimisation thus intervals important. optimisation should consider production, capacity system udder health.
