ABSTRACT

Twenty (20) West African Dwarf (WAD) bucks were used to investigate the effects of frequency of electroejaculation (EE) on spermiogram characteristics and physiological parameters. They were divided into four groups consisting of five bucks and ejaculated once a day (Group I), twice a day (Group II), thrice a day (Group III), and four times a day (Group IV) for 3 successive days in a completely randomized block design. The results showed that some important sperm characteristics such as progressive sperm motility, sperm concentration and mass activity were similar (P>0.05) among the different groups. Some biochemical parameters such as Cortisol, Na+—, K+— and Glucose were similar among the various treatment groups except the serum testosterone level that increased in response to increased frequency of ejaculation. Activities of the enzymes Alanine Aminotransferase (AAT), and Aspartate Aminotransferase (AST) Alkaline Phosphatase (ALP) were not affected by elevated EE intensity (P > 0.05). The results showed that rectal temperature, pulse rate, heart rates, and skin temperature were similar (P > 0.05) among the various treatment groups. Respiratory rate and scrotal temperature however increased with increasing frequency of ejaculation (P< 0.05). The findings indicate that frequency of EE has no deleterious effect on sperm characteristics.
