Abstract
The aim of the present study is to evaluate the effect of Clinoptilolite (Zeolite) addition to the broiler diets with or without phytase enzyme on blood constituents and carcass traits. Total number 594 one-day-old broiler chicks (Ross 308) were randomly divided into nine equal experimental groups with 3 replicates of 22 birds in each for 35 day of age. Birds of the 2 nd and 3rd groups were fed diets contained 0.05% and 0.075% phytase (5000 FTU/g), the 4 th group was fed diet contained 1% Zeolite, the 5th and 6th groups were fed diet containing 1% Zeolite with 0.050% and 0.075% phytase (5000 FTU/g), respectively, the 7th group was fed diet containing 2% Zeolite, the 8th and 9th groups were fed diet containing 2% Zeolite with 0.05% and 0.075% phytase (5000 FTU/g), respectively. While, the first group presented as basal diet without Zeolite and/or phytase supplementation. Body weight and feed conversion at 35 days of age were significantly improved by Zeolite addition and broiler chickens treated with 0.05% phytase diet had the best body weight. Blood hematology was not affected by Zeolite or phytase treatments, while serum total protein concentration was significantly increased compared with those of the control group. Also, Zeolite addition had a significant decreasing effect on broiler chicken’s cholesterol and triglyceride concentrations, as well as phytase supplementation had a significant decreasing effect on broiler chicken’s cholesterol, triglyceride and low density lipoprotein values. At the end of the experiment, it can be seen that carcass and dressing percentages significantly improved with Zeolite treatments. Generally, it can be considered that natural Zeolite addition to the broiler diets supplemented with or without phytase enzyme enhanced physiological status included serum protein and lipid profile.
