Abstract

Assam Hill goat (AHG) is an important goat germplasm found in Assam and its adjoining areas of India. The study was designed with an objective to study the semen characteristics and freezability of AHG buck semen using Tris -Egg yolk-Citrate-Fructose diluent. The  mean values of fresh semen characteristics in AHG bucks viz., ejaculate volume (ml), initial sperm motility (%), sperm concentration (x106/ml), live sperm (%), sperm abnormality (%), HOST-reacted sperm (%) and intact acrosome (%) recorded were 0.39 ± 0.01, 77.97 ± 0.73, 3201.00 ± 143.78, 83.02 ± 0.65, 7.66 ± 0.73, 66.95 ± 0.74 and 93.34 ± 0.51, respectively. Mean values for post-thaw semen characteristics i.e., sperm motility (%), live sperm (%), HOST-reacted sperm (%) and intact acrosome (%) were 55.39 ± 0.97, 71.01 ± 0.78, 54.77 ± 0.55 and 82.16 ± 0.43, respectively. It can be concluded that AHG bucks donate acceptable quality of semen which can be frozen successfully in Tris-Egg yolk-Citrate-Fructose diluents for using in Artificial Insemination.
