Semen Characteristics in Growing Shami Male Goats


Abstract in English

This Study was carried-out at Shami Goat Improvement Station in Karahta. Ten growing Shami male goats, aged 8 months, housed and managed under the same conditions were used to study the semen characteristics. Artificial vagina was used to collect semen at weekly intervals, for 13 months to determine the volume, motility, pH, and sperm concentration using Neubaure- Spectrophotometer and Spermiodensimeter techniques. Overall averages and standard errors of volume, motility, concentration, and pH were 0.9 ± 0.07 ml, 65.24 ± 1.41%, 3.57 ± 0.14 billion/ml, and 6.52 ± 0.07, respectively. Seasonal variations were observed. A positive significant correlation between volume and motility (r= 0.42, P<0.01) was found, while negative correlations (P<0.01) between pH and other studied semen characteristics were recorded. Linear equations for detecting sperm concentration as measured by either, Spermiodensimeter or Spectrophotometer were obtained.
