Description A biological trial was conducted to evaluate the effect of enzyme complexes for enhancing the nutritive value of low cost agro-industrial by products like sunflower meal (SFM) and deoiled rice bran (DORB) in the diets of laying hens in the second phase of production.

The performance and health parameters were studied for six periods of 28 days each. The design was a 4 X 3 factorial experiment using 288 BV 300 layers subjected to 12 dietary treatments with four replicates of six birds each. Enzyme A or B was supplemented to increasing inclusions (10, 15, 20 and 25%) of SFM and DORB based diets and hence 12 dietary treatments were made. Enzymes A and B had different activities of xylanase, pectinase, cellulase and phytase. Enzyme B had amylase in addition. Both these enzymes were added at the rate of 0.5 kg/ton of feed.

The results of the laboratory analysis of feed ingredients SFM and DORB were higher in NSP contents (pentosans, cellulose and total NSPs) than that of maize and soybean meal. The rising levels of SFM and DORB in the diets simultaneously increased the pentosans, cellulose and total NSPs and decreased the pectin contents in the diets 1 to 4 also. The increased levels of SFM and DORB in the diet had significantly (P
