PENGARUH pH MUKOSA VAGINA SAAT INSEMINASI BUATAN TERHADAP NON RETURN RATE (NRR) DAN CONCEPTION RATE (CR) PADA SAPI PERAH DI KSU TUNAS SETIA BARU KABUPATEN PASURUAN

This study aims to find out the vaginal mucosa during artificial insemination against Non Return Rate (NRR) and Conception Rate (CR) in the highlands. Sixty female dairy cows were used as samples in this study. The pH of the vaginal mucosa is measured by digital pH meter on each dairy cow at the time of artificial insemination. Non Return Rate (NRR) observation was performed on the 21st day after insemination and Conception Rate (CR) was performed on day 60 after insemination. The effect of pH of the vaginal mucosa during artificial insemination is in the range of 6.8 to 8.5. pH is produced in the range of 7.2 with the number of 12 pregnant dairy cows. In this research yields very good percentage in dairy cow for Non Return Rate (NRR) that is 88,33% and Conception Rate (CR) is 86,79%
