Sažetak
This study investigated the effect of dietary inclusion of Brewers Dried Grains (BDG) supplemented with Grandizyme® enzyme as a partial substitute for maize in layers diets. One hundred and twenty Isa-Brown laying hens were randomly allotted to three diets formulated with 0 (control), 10% and 20% BDG, and fed for 12 weeks. There were 4 replicates of 10 birds each in a dietary treatment. Feed mintake, hen day production and net profit generated from the sales of eggs were msignificantly (p<0.05) highest for diet 3. Cost of feed /kg significantly (p<0.05) reduced from N35.50 (€0.17) for diet 1 to N33.69 (€0.16) and N31.38 (€0.15) respectively for diets 2 and 3. Substitution of maize with 20% BDG supplemented with Grandizyme® enzyme resulted in better performance and gave a higher net profit compared with other treatments; and could be adopted to alleviate the problem of high cost of maize.
