Quality of boer goat liquid semen in coconut water diluent with egg yolk addition during cold storage

The research aimed to analyze the effect of young green coconut water diluent with egg yolk in Boer goat liquid semen quality at cold storage. This study used an experimental laboratory with 4 treatments and 10 replications. The treatments tested were: P0 = CEP-3 + 10% egg yolk + 0.4% egg white, P1 = 90% coconut water + 10% egg yolk, P2 = 85% coconut water + 15% egg yolk, and P3 = 80% coconut water + 20% egg yolk. The variables analysis was individual motility, viability, abnormality, intact plasma membrane, and intact acrosome hood. The data were analyzed using Analysis of Variance (ANOVA), and the difference between treatments continued with Duncan Multiple Range Test. The result showed significant differences in individual motility, viability, intact plasma membrane, and intact acrosome hood (P0.05). In conclusion, the combination of coconut water + 20% egg yolk could be recommended for the diluent of Boer goat liquid semen in cold storage for up to 3 days.
