An experiment including 108, day old Vencob broiler chicks was conducted to see the effect of using enzyme in layers containing various combinations of coarse cereals and oilseed meals. These pullets were allotted randomly to six dietary treatments. Control diet-I (T 1) was formulated using maize, deoiled rice polish, soybean meal, fishmeal, minerals and vitamin supplements. While, control diet II (T 2) was formulated without fishmeal. Further, in diets T 1and T 2, maize was exclusively used as cereal and soybean meal as vegetable protein supplement. While, in diet T 3, 85% of maize and 70% of soybean meal was replaced by using equal proportions of sorghum and ragi and niger and sesame cakes, respectively. In diet T 4 50% maize was replaced by using ragi and soybean meal was completely replaced by incorporating niger and sesame cake in equal proportion. While, in diet T 5, maize as well as soybean meal was completely replaced by using sorghum, ragi, niger, and sesame cake in equal ratio. In diet T 6, 85% of maize and 70% of soybean meal was replaced by using equal combination of sorghum and ragi and niger and sesame cake, respectively. Diet T 3 and T 6 were same except in T 6 lysine was not supplemented. In diets T 4, T 5, and T 6 enzyme Beetazymes ( b-D glycosidase, cellulases, proteases, amylases, phytase) was added @ 50g/Q.
Enzyme was found to have significant effect on the retention of nutrients. Maximum % retention of most of nutrients except CF and EE was seen in birds allotted 2 (T 2) diet containing without supplemental enzyme and lysine. It differed significantly with the rest of diets. Only % EE retention was maximum in groups 4, 5, 6 which were supplemented with enzyme. While, maize-soy diet (T 1) had significant effect on the % retention of nutrients namely CP, C and Ca except DM, EE, NFE, P and energy retention. Thus, use of enzyme had no effect on the % retention of nutrients.
