Abstract

This research aims to determine the influence of environmental temperature differences between highlands and lowlands toward reproduction ability of local Friesian Holstein dairy cows artificial insemination acceptor. Farm is a business activity in an effort to increase the operational benefits of livestock through the application of certain techniques which are economically profitable. This research was conducted in sub-district Sendang and Nongkojajar as highlands and sub-district Grati district Pasuruan, Surabaya and Gresik as lowlands. Result of the research was analyzed descriptively and gained an average of temperature and the humidity in the highlands respectively 26,3±1,71°C and 76,30±5%, while in the lowlands obtained an average temperature of 31,4±2,02°C and a humidity of 62±9%. Results acceptor reproduction ability of dairy cattle inseminated using parameters non return rate, conception rate and service per conception result in highlands values obtained NRR 85.5%, CR 71,1% and S/C 1,38 whereas lowlands result NRR 80%, CR 66,7% and S/C 1,45. The results obtained showed a better value to dairy farming at highlands. Based on statistical analysis using linier regression showed that there is linear correlation between environmental temperature and reproduction ability in local Friesian Holstein dairy cows’ acceptors artificial insemination. But the effect was small or not significant.
