Abstract

A feeding trial of 84 day was conducted to evaluate the performance and egg quality characteristics of layers fed different combinations of Cassava Root Meal (CRM) and Bambara Groundnut Offal (BGO). Four layer diets were formulated such that diet T1 (control) contained 50% maize, while diets T2, T3 and T4 contained CRM and BGO in the ratios of 2:1, 1:1 and 1:2, respectively, completely replacing maize. Ninety six Shaver Brown point-of-lay pullets were allotted into four experimental groups of 24 pullets each and each group was replicated twice with eight pullets per replicate. These birds were randomly assigned to the experimental dies in a Completely Randomized Design (CRD) experiment. Results indicated that daily feed intake was significantly (p<0.05) higher for layers on diet T3 and T4 than those on diet T1. Daily feed intake was significantly higher (129.48 and 128.60 g) for layers on the diet (T1) than other treatment groups, while layers on diets T2, T3 and T4 recorded higher egg weights than those on the control diet. Hen-day production was significantly (p<0.05) higher among layers fed diet T1 (control) than those on the other treatment groups which contained different combination ratios of CRM and BGO. FCR was highest (2.11) and lowest (1.99) for layers fed diets T3 and T2, respectively. Yolk index, albumen index and yolk colour showed no statistical difference (p>0.05) in all the treatment groups. However, layers on diet T4 and T3, respectively recorded the highest (0.35 mm) and lowest (0.33 mm) shell thickness while those on diet T1 and T4, respectively recorded the highest (69.64) and lowest (60.62) Haugh units. It would appear that the different combinations of CRM and BGO significantly depressed the performance of laying birds.
