The aim of the experiment was to investigate the effect of microbial enzyme
supplements on egg production and the nutrient digestibility of laying hens. A
total of 360 twenty-one-week-old Hisex Brown laying hens were assigned to
three treatments with four replicates of 30 birds each using a completely
randomized design and reared for 30 days. The treatments consisted of 1) A
basal diet provided according to the recommended feeding standards (as the
control group), 2) a basal diet supplemented with proteinase enzyme at a
concentration of 10 U/kg, and 3) a basal diet supplemented with phytase
enzyme at a concentration of 1000 FTU/kg. Supplementation of proteinase
enzyme increased (P < 0.05) the retention percentage of dry matter and crude
protein in laiyng hens compared to the control treatment. and phosphorus
retention increased in laying hens by using of the enzymes. The addition of
proteinase enzyme to the diet increased body weight gain of laying hens
compared to other treatments. Feed convertion ratio improved in laying hens
recieved enzyme supplements (P < 0.05). The dietary enzymes
supplementation increased the egg weight and egg mass than those fed with the
enzyme-free diet (P < 0.05). The Thickness of eggshell increased by using of
phytase enzyme than other treatments. Also, ash content of eggshell increased
in treatments supplemented by both of the enzymes. According to the results of
the experiment, the addition of proteinase and phytase to the diet could be
effective in improving the performance of laying hens and the quality
characteristics of eggshell |
