Seminal characterization of some elite Ethiopian indigenous breeds of bull

Abstract

The semen of six indigenous bulls consisting of Barca, Boran, Horro and Sheko breeds maintained at National Artificial
Insemination Center (NAIC), Kaliti, Addis Ababa, (Ethiopia) were evaluated for physico-morphological parameters, biochemical
parameters (GOT, GPT, ACP, ALP, total protein) and hormonal assay (testosterone). Semen was collected for
thirteen weeks, once a week by using artificial vagina. The overall mean (SE) value for the semen characteristics studied were
volume 4.84 (0.20) ruJ, mass motility 3.15 (0.11 ), individual motility 68.72 (1.37) %, concentration 1.54 (0.07) billions/ml,
total count 7.35 (0.4 7) billions/ejaculate, viable number 5.10 (0.33) billions/ejaculate, total morphologically normal number
7.12 (0.45) billions/ejaculate, live percentage 79. 73 (0.65), percent morphologic normal 94.70 (0.38), per cent normal acrosome
96.99 (0.60), GOT I 530.91 (60. I 5) u/1, GPT 131.99 (9.36) U/L, ALP 3333.98 (608.84) U/L, ACP 8003.68 (716.06) U/L, total
protein 7.38 (0.26) gm/di, testosterone 2.84 (0.3) ng /ml. It could be concluded that seminal attributes were comparable to
normal fertile bulls of other breeds based on the evaluation of fresh semen parameters.
