Pengaruh Umur Beranak Pertama Terhadap Performa Produksi Susu Sapi Friesian Holstein di BBPTU-HPT Baturraden
Abstract: The objective of
this study was to observe effect of first cavling Friesian Holstein age on milk
yield performance at BBPTU-HPT Baturraden. This study was conducted using 150
sets of weekly recording of milk yield from 350 Friesian Holstein cows. Milk
yield was calculated by using time interval method (TIM) which was equvalent to
ME 305 days. The data were analysed using polynomial regression model. Result
of the study indicated that BBPTU-HPT has made efforts to improve the age first
calving, but has an impact on longer day open and shorter period of lactation
with longer dry period so that calving interval has been longer than what’s
been indicated not efficient and optimal. The age first calving significant
through milk yield followed the pattern of linear regression
