Online published on 27 May, 2021. Abstract Semen samples were collected by artificial vagina method twice in a week from nine Surti bucks. The ejaculates were divided in to three groups based on the body weight of bucks viz., G1-up to 30 kg (n=112); G2–30.1 to 40 kg (n=98) andG3-above 40 kg (n=78). Mean density was significantly (P<0.05) highest in G3. Semen volume (ml) was significantly (P<0.01) lower in G1. The average mass activity, progressive motility, live sperm and HOS reacted sperm were non-significantly differed between all the groups. The average sperm concentration was significantly (P<0.01) higher in G3. The mean total sperm count and semen index were significantly (P<0.01) increased with increase in body weight. The average progressive motility at 30 min intervals was non-significantly higher in G2. Average motility degeneration rate at 30, 60 and 120 min was non-significantly higher in G1. Average normal sperm percent was non-significantly differed between all the groups. Top Key words Artificial vagina, Body weight, Buck, Motility degeneration rate, Semen parameters. Top |
