Parameters evaluated included egg weight percent egg production feed intake egg mass and feed efficiency. Birds on the control and boiled CBS diets ate significantly P less than 0.05 more feed than others. Egg weight and egg mass were higher P less than 0.05 on the boiled CBS diet.

Abstract

A previous trial evaluated possible improvement of cocoa bean shell CBS utilization in layers mash through sun drying boiling leaching alkali and urea treatments of CBS at 10 dietary maize replacement level. The results revealed that boiling and urea treatment were most practicable and profitable. The present study investigated the effects of processing techniques boiling and urea treatments at higher levels of CBS on the performance of egg _ type birds. A total of 5 dietary treatments which included the control 0 CBS diet and a commercial diet were used in this trial. The other diets contained 20 maize replacement with each of untreated CBS Urea treated CBS and Boiled CBS. Fifty individually caged point-of-lay pullets were allocated among the diets in a completely randomized design. Each bird representing a replicate was offered feed and water ad libitum throughout the 12-week experimental durations. Parameters evaluated included egg weight percent egg production feed intake egg mass and feed efficiency. Birds on the control and boiled CBS diets ate significantly P less than 0.05 more feed than others. Egg weight and egg mass were higher P less than 0.05 on the boiled CBS diet. Due to the positive responses of the birds on the CBS diet it was concluded that boiling technique enhanced the effective utilization of CBS in laying hens.
