ABSTRACT
A study was conducted to evaluate the effect of 20% inclusion replacement of maize with peeled cassava root meal and unpeeled cassava root meal with and without enzyme inclusion. A total of 90, 42 weeks old black Harco layers were divided into 6 groups with 3 replicate for each group. Each replicate had 5 birds. The 6 diets comprise of control, peeled cassava root meal and unpeeled cassava root meal, with and without enzyme. Each diet was offered ad libitum to the birds for a period of seven weeks. Records were kept on body weight, feed intake and egg production. Eggs were sampled for both internal and external quality parameters. The results showed that there were no significant effects on body weight, feed conversion ratio and henday production (p>0.05) but there was significant effect on feed intake of cassava based diet (p<0.05) which was higher than the control diet. The result also showed that there was significant effect on the egg weight of birds fed PCRM (p<0.05) which was the highest. The control diet had the best performance.
The result showed that cassava and enzyme inclusion had no effect on improving egg production and quality in any of the diets.
