Abstract

The continuous scarcity and high cost of livestock feed has necessitated the search for alternative ingredients. An experiment was conducted to determine the response of laying hens fed diets with iburu offal (IO) replacing maize. 162 laying hens were distributed to 6 diets with IO replacing maize at 0%, 5%, 7.5%, 10%, 12.5% and 15%. The 0% served as control. Each diet has 27 replicated 3 times and 9 hens per replicate in a completely randomized design. Feed was served twice a day but drinking water was provided ad libitum. The results showed that egg production rate (EPR), feed efficiency per dozen eggs (FE/dozen eggs) and feed efficiency per egg mass (FE/egg mass) were significantly (P<0.05) affected. Hens fed 12.5% IO had higher EPR, better FE/dozen eggs and FE/egg mass than those fed 0% IO while hens fed 5-10% and 15% IO had lower EPR, poor FE/dozen eggs and FE/egg mass comparable to those fed 0% IO. The other performance parameters were not significantly (P>0.05) affected.  The entire egg quality parameters were also not significantly (P>0.05) affected except egg weight (EW) and egg yolk colour that were significantly (P<0.05) affected. Hens fed 12.5% IO also had higher EW and deep-yellow yolk than those fed 0% IO while hens fed 5-10% and 15% IO had lower EW and pale-yellow yolk similar to those fed 0% IO. Cost of feed per 100kg and 1kg decreased with increased IO in the diets. The diet with 0% IO had higher cost per 100kg and 1kg feed while diet with 15% IO had least. Cost of Feed per dozen eggs and cost of feed per egg mass fluctuate. In both parameters 0% IO had the higher cost while 12.5% IO had least. It was concluded that IO can replace maize at 12.5% in laying hens’ diets without negative effect on egg production and egg quality. Also, a drastically reduction of cost of feed was recorded.
