Abstract

Milk production curve describes the period from lactation onset after calving until the cow’s milk dries up. The shape of the milk production curve follows a regular pattern, milk production at the beginning of lactation continues to increase until the peak of production, then begins to decrease in production until the lactation period ends. The research of "Daily Milk Production Curve on First and Second Lactation in Local Friesian Holstein Dairy Cows at BPPIB-TSP Bunikasih" was conducted in March 2020. The purpose of this study was to find out the shape of milk production curve and the average estimated milk production of 365 days by using regression model of Ali-Schaeffer. The data used were 3.372 records from 109 local FH dairy cows at lactation 1 and 2 from 2016 to March 2020. The results showed that the milk production curve in lactation 1 and 2 of the Ali-Schaeffer regression model was on the line that the curve of actual milk production. The correlation between estimated milk yield of Ali-Schaeffer and actual milk yield of 365 days in lactation 1 was 0.988 and in lactation 2 was 0.983. The average estimated milk yield of 365 days at BPPIB-TSP Bunikasih in lactation 1 was 3.662 kg and in lactation 2 was 3.702 kg.
