Effect of Ecotype on Semen Characteristics of Sahel Goats in Borno State
A research was conducted to study the influence of ecotype on semen characteristics in 5 white and 5 brown ecotypes of sahel goats. Semen was collected from eight to forty-eight weeks of age and analyzed for semen characteristics and abnormalities. Body weights and scrotal circumference were also measured from three months to 1 year of age on a monthly basis. Analysis to determine the difference between the two ecotypes was performed. The only significant difference between the two ecotypes was in body weights, scrotal circumference and protoplasmic droplet abnormality. It was concluded that there was no superiority in the mean semen characteristics between the white and brown ecotypes of sahel bucks. This may be due to the total absence of coordinated breeding programmes evidenced by random indiscriminate mating in the goat population in Borno pastoral setting. This suggests that the conservation and preservation of most cherished traits are un-achievable under the current husbandry practices.
