Abstract
In Indonesia the Holstein dairy cow is maintained by the large scale dairy farms on the middle lands. How far the empirical data of milk production of Holstein dairy cow in Indonesia is rare published. Based on the above description it is very interesting to perform the analysis of milk production of Holstein cow kept on the middle land in West Java. The research method was observationally conducted on milk production from the first until the sixth lactation period of Holstein dairy cow. The population samples from middle plain are 1248 heads of Holstein lactating cows maintained for three years. The milk production data are standardized to 305 2x ME. Based on the result and discussion it is found out that the range of real milk production is 1,068-9,696 l within 180-607 days lactation period with average lactation period 363.99±96.61 days, total milk production 3,761.14±1,458.34 l, and milk production 10.48±3.44 l/day. The Holstein milk yield of 305 days 2x ME is ranged in 1,088-8,313 l with average per lactation 4,136.60±1,518.01 l and average per head per day 20.37±17.76 l. It is suggested that to maintain the genetic potential of Holstein dairy cow the management and feeding must be considered.
