Abstract

Three bucks each of Local Crossbred and Boer were used to study libido and semen quality. Bucks were about two years of age and their weights ranged between 18 to 45 kg. An artificial vagina was used to collect semen at 3 days intervals starting in December 2007 and ending in February 2008. The study showed that the Local Crossbred possessed the greatest libido by recording the shortest time to mount (10. 78 ± 1. 10 sec) and the shortest time to ejaculate (42.83 ± 8.60 sec) as compared to Boer (57.90 ± 6.03 sec) and (90.27 ± 9.25 sec). The Boer showed the least number of mounts per ejaculation (2. 72 ± 0.20) as compared to Local Crossbred (2.82 ± 0.33). Compared to Boer the Local Crossbred produced greater volume of semen (0.88 ± 0.03 mL), had greater percentage of live sperm (78.38 ± 1.25%) and possessed the greatest sperm count of 3.78 ± 0.08 x 109 sperm/mL. The testicle circumference and breadth of bucks was highly correlated (P < 0.01) with volume, percentage live of sperm and concentration of sperm between Local Crossbred and Boer and negatively correlated with libido test in Boer only. Volume of semen, time to mount, time to ejaculate, testicle circumference and breadth were significantly greater in Local Crossbred as compared with Boer. The data indicated that the libido was better and semen quality and quantity was greater in Local Crossbred goats as compared to the Boer. It can be said that the relationship between testicle size with libido and semen quality can be used to select bucks for breeding.
