Abstract

This research was conducted in Badung and Tabanan Regencies with a survey method on bali cow farmer group
where the cows as artificial insemintion (AI) acceptors were in the the program of special effort on acceleration of
pregnant cattle and buffalo population (Upsus Siwab). Sampling was carried out by purposive random sampling
with 74 cows were in Badung and 61 cows were in Tabanan. Data obtained from interviews and recording from
farmers, farmer groups and inseminator staffs. Data collected included: age of cows, age of first mated, calving
rate, service per conception, gestation period, and post partus heat. Data generated were analysed using descriptive
statistics and reproductive performance of bali cows as AI acceptors between Badung Regency and Tabanan Regency
was analysed using Two Independent Sample T Test. Results showed that the average age of cows in Badung and
Tabanan was 4.23 ± 2.00 years and 4.50 ± 2.90 years and the age at first mated was 1.74 ± 0.49 and 1.900.38 years
respectively. Calving rate of cows as AI acceptors in Badung and Tabanan Regencies were 56.75% and 40.98%
respectively. Service per conception is 1.62 ± 0.39 times and 1.90 ± 0.38 times, respectively. The average of gestation
period of cows in Badung 9.63 ± 0.52 months tended to be longer than of 9.45 ± 0.22 months in Tabanan, whereas
the post partus heat were 3.06 ± 0.94 months and 3.53 ± 1.03 months, respectively. In conclusion, the calving rate of
cows in Badung was greater than of in Tabanan and the post partus heat of AI acceptor cows in Badung was shorter
than of in Tabanan.
