Abstract
The optimum level of palm oil supplementation of a layers’ basal diet with 17% protein (N × 6.25) and 2.74 M.E./g. (calculated) appeared not less than 5.0% for egg production of White Rock breeders in Southern Nigeria. The efficiency of conversion of feed to egg, weight gains and the Haugh unit but not size and shell thickness also improved with palm oil supplementation of the basal diet. The optimum levels of dietary palm oil supplementation for percentage fertility and for hatchability of fertile eggs appeared to be 5.0–7.5% and 2.5–7.5%, respectively. The hatching weight of chicks was not affected by dietary palm oil.
