The experiment was conducted on 500 semen samples from 40 healthy breeding bucks (20 Boer bucks and 20 Alpine bucks) aged between 10 and 18 months, raised and managed at a breeding goat farm in Phong Dien District, Can Tho City. The research findings revealed the following: the semen volume of Boer bucks averaged 1.24 ml, while Alpine bucks averaged 1.16 ml (P>
0.05)
sperm concentration was similar between the two breeds, with Boer bucks achieving 3.12 billion/ml and Alpine bucks 3.07 billion/ml
sperm motility was 81.21% and 81.06% respectively (P>
0.05)
the abnormal sperm rate in Boer bucks was 9.27%, and in Alpine bucks, it was 9.43% (P>
0.05)
the semen pH for both breeds averaged 6.90. The total motile sperm count of Boer bucks (3.13 billion/ml) was higher than that of Alpine bucks (2.88 billion/ml). Boer bucks exhibited a greater buffering capacity (938.1) compared to Alpine bucks (862.7), indicating a better ability to maintain stable pH under varying conditions. However, the semen of Alpine bucks had a higher specific gravity (1.09) and viscosity (58.7) compared to Boer bucks (1.05 and 54.9, respectively), suggesting that the semen of Alpine bucks is denser and more viscous.Thí nghiệm được tiến hành trên 500 mẫu tinh dịch của 40 dê đực giống (20 dê đực giống Boer và 20 dê đực giống Alpine) dê đực giống khỏe mạnh, có độ tuổi từ 10 đến 18 tháng tuổi, được chăm sóc, nuôi dưỡng tại trại chăn nuôi dê giống huyện Phong Điền, Thành phố Cần Thơ.
