ABSTRACT
The fact that specific breeds of livestock were developed to achieve specific objectives has been reported by several researchers but few or little information are available on the performance of these specific breeds in varied ecozones, hence a 365 days laying period of Bovans Goldline layers, a Nigerian commercial laying strain was assessed in oil producing environment of Niger Delta, Nigeria. Results of the experiment revealed a better fit for the quadratic function in predicting egg production curve with coefficient of determination (R2) values of 80.65± 0.8, 71.14±0.65, 82.50±0.07 and 73.08±0.02 per cent were obtained for linear, inverse, quadratic and exponential functions fitted for the data. However, better performance was recorded in months of June through August but later declined till February. Hence it can be stressed as a point of findings that period of year and ecological zone has influence on performance of Bovans Goldline layers in oil producing zone of Niger Delta, Nigeria.
