THE IMPACT OF VARIOUS LACTOSE AND SOYBEAN MILK CONCENTRATION IN THE PRESERVED BOER GOAT SEMEN QUALITY

Abstract

This study aims to determine the effect of lactose and soybean milk concentrations as semen extenders for Boer goat semen. The research method employed a Completely Randomized Design (CRD), consisting of four treatments and six replications, namely: 80% lactose + 20% egg yolk as a control (P0), 97% lactose + 3% soybean milk (P1), 95% lactose + 5% soybean milk (P2), and 93% lactose + 7% soybean milk (P3). The semen samples were then stored at 3-5oC, and motility and live spermatozoa percentage were observed daily for four days. The results obtained from the research indicated that the concentration of soybean milk significantly affected (P<0.05) the motility and live spermatozoa percentage of Boer goats after cooling on the third day. The combination of 3% soybean milk with 97% lactose as an extender resulted in improved motility and live spermatozoa percentage in Boer goat semen.
