Abstract

The present study was done to observe effect of agroclimate on milk production and prevalence of sub-clinical mastitis of local Holstein-Friesian dairy cattle in Indonesian small holder dairy farms. The research side were located in Region of <1000 masl and ≥1000 m above sea level (asl) in west Java. Data were obtained from 133 small holder dairy farms included 336 dairy cows in normal lactation period. Parameters observed were agro-climate condition, feed consumption, milk production and milk quality, and sub-clinical mastitis prevalence. Result sowed that THI at <1000 m asl had a range of 76.1-76.7 leads to mild heat stress, while THI at ≥1000 m asl had a range of 66.2 - 66.8 which makes comfort environment to the dairy cow. Differences in feed consumption (P<0.01), milk production and quality (P<0.05) were found among two altitude study location. Milk production at ≥1000 m asl was 2.3 kg higher than at <1000 m asl. The udder health status was also different, a 51% of total sample at <1000 masl was detected sub-clinical mastitis (SCM) as high criteria, while 42% samples that were collected at ≥1000 m asl detected sub-clinical mastitis as middle criteria. In conclusion, agro-climate condition (THI) affect animal’s comfort, milk production and sub-clinical mastitis prevalence.

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
