ABSTRACT: The quality of liquid semen with coconut water as diluent could be preserved
up to 3 to 4 d during cold storage at 4 - 5
oC. In this research, the successful insemination rate
of coconut water-based diluent Boer goat liquid semen was observed to understand the
application of coconut water as semen diluent. The materials used in this research were 5 to 7
months Viridis coconut water, liquid semen from 3 y old Boer buck, 30 does for acceptor, and
Tris-aminomethane added with 10% egg yolk (EY) as a control diluent. The Boer semen was
collected once a week by using artificial vagina, diluted and then stored before used for
insemination. The insemination was done by using intra-cervical method at position 3, started
with estrous synchronization by using 2 mL PGF2α. The research was conducted as
experimental method under randomized group design with two treatments, that were Trisaminomethane + 10% EY (P0) and coconut water + 10% EY (P1). All of the treatments were
repeated for 15 times and the collected data were analyzed with Pearson’s chi square with
Genstat 18 program. The observed variables include non-return rate and kidding rate. The
results showed that the first non-return rate of P1 were 93.33% and in P0 were 73.33%, while
the second non-return rate of P1 were 93.33% and in P0 were 80%. Furthermore, the kidding
rate of P1 were 40% and P0 were 66.66%. The Pearson’s chi square analysis showed that there
was no effect of coconut water as semen diluent to the kidding rate. The research concludes
that the usage of coconut water as semen diluent did not affect the successful insemination rate
of Boer goat
