Sperm Quality of Gembrong Goat in Bali, East Java and North Sumatera after Extended with Citrate-egg Yolk, Tris-egg Yolk and Andromed®

Abstract

The aims of this study were to compare tris-egg yolk and citrate-egg yolk extender on the quality of Gembrong goats semen in three different place, Bali, East Java, and North Sumatera. Semen was collected from 9 heads aged 2-4 years using arti cial vagina. Semen was evaluated macroscopic and microscopically. Collected semen devided in two tubes and extended with citrate-egg yolk (CEY) and tris-egg yolk (TEY). There were signi cant differences (P<0.05) on the motility between CEY and TEY extender in the three places Bali (CEY (85 ± 3.5) TEY (90 ± 2.1)); East Java (CEY (82 ± 2.5) TEY(88 ± 3.1)); and North Sumatera (CEY (82 ± 4.5) TEY (85 ± 4.1)). There were no signi cant differences on viability and abnormallity between CEY and TEY extender in the three places, viability in Bali (CEY (91 ± 3.5) TEY (92 ± 4.1)); East Java (CEY (88 ± 2.5) TEY(89 ± 3.1)); and North Sumatera (CEY (86 ± 2.5) TEY(85 ± 3.1)); abnormallity in Bali (CEY(11 ± 1.5) TEY (10 ± 1.1); East Java (CEY (13 ± 2.5) TEY (11 ± 2.1); and North Sumatera (CEY (16 ± 4.5) TEY (14 ± 3.1)). In conclusion CEY support the sperm motility as good as TEY of Gembrong goats in three places Bali, East Jawa, and North Sumatera respectively.
