Abstract
The development of testicular glutamate oxaloacetate (GOT) and glutamate pyruvate (GPT) transaminases and of 5'-Nucleotidase was monitored in the male Nigerian fowl. The findings indicated triphasic and monophasic oscillations of GOT and GPT respectively with age. 5(1)-Nucleotidase was found to decrease with increase in the chronological age of the chicks. Furthermore, while GOT and GPT exhibited cubic and quadratic relationships respectively with age and testicular weights, 5(1)-Nucleotidase was related to both variables in a quadratic manner. The results are discussed in terms of spermatogenesis which may bear profoundly on the overall reproductive performance traits of the Nigerian cockerel.
