Abstract

Data from 32 Isa Brown (layer hype) cocks aged 10 months were used to determine the effect of crude oil contaminated feed on their semen quality. There were four treatment groups with pro replicates each. Treatment T1 which received crude oil free diet served as control. Treatments T2, T3, and T4 received crude oil contaminated feed at the rate of 1.0ml, 2.0ml and 3.0ml per kg of feed, respectively. Both feed and water were provided ad libitum. The experiment lasted for five weeks during which each cock ejaculated two times a week using the massage technique. The results indicated a highly significant (p<0.01) decrease in semen volume from treatments T1 to T4 while significant (P<0.05) decreases in sperm concentration and sperm motility were observed from treatments T1 to T4 Results also showed a significant (P<0.05) increase in percentage dead sperm and total abnormal sperm from treatments T1 to T4 The effect of weeks was significant on body weight, semen volume, sperm concentration and percentage dead sperm. Treatment by week interaction was significant (P<0.05) only on body weight. It was concluded that crude oil contaminated poultry feed had a deleterious effect on semen quality of cocks.
