Abstract

ABSTRACT

Abstract: Reproductive performance is one of the important factors that needs to be known in supporting the efficiency of beef cattle breeding programs. This research aims to determine the reproductive performance of Bali Cattle and Simental Cattle in UP2PKH Woha District, Bima, West Nusa Tenggara. The cows used were 5 Balinese cattle and 5 Simental cattle aged 2 years who had already given birth. The research method used is descriptive quantitative. An Estrus Postpartum shows a Bali cattle first estrus after calving an average of 38.00±2.37 days. Meanwhile, Simental cattle average 83.80±1.72 days. In Simental cattle, the service period is 77.2±2.86 days, while Bali cattle have an average of 58.8±4.12 days. Days open for Bali cattle ranged from 95.2±3.25 days while Simental cattle ranged from 160.6±28.58 days. The number of times serviced until pregnancy occurred in Balinese cattle that were artificially inseminated with Balinese cattle breeds ranged from 1-7 times with an average of 3.42±2.31 times. Meanwhile, the service per conception value for cattle from crossing Bali cattle with Simental cattle ranges from 1 to 4 times with the average figure being 2.8±2.23 times. The calving interval in simental cattle is 366-480 days or 12.2-16 months with an average of 500.2±4.71 days. Meanwhile, Bali cattle mothers have a calving interval of 12-14 months with an average of 334±46.
