The Nutritive value of East Azerbaijan bakery waste (Biscuit Waste) in broiler chick diets

This research accomplished for studying the effects of East Azerbaijan province of Iran bakery factory wastes (biscuit) in rations of broiler chickens on performance، carcass characteristics and bloody parameters (LDL، HDL، Triglyceride and Cholesterol). This bioassay was evaluated by using 600 Ross 308 broiler chicks and completely randomized design with 5 treatments and 5 replicate were used in this experiment in 15 to 49 d of age. Five diets were formulated to contain biscuit waste to 0% control، 10، 15، 20 and 25 percent as replacement for corn fraction in broiler diets. The result of bakery waste replacing for corn had significantly effects on broiler performance (P<0. 01). The highest feed intake and weight gain was related to broiler chicks fed with 25 % of biscuit waste diets. Biscuit waste replacing in all level to corn portion، improved the feed conversion ratio since of 4th week to end of experimental period and the best feed conversion ratio was relative to level 25% of biscuit waste than control group (1. 85 vs. 1. 91) (P<0. 01). The broiler chicks fed with biscuit waste had a lowest abdominal fat and highest breast weight and empty body weight (P<0. 01). Blood parameter analyzed result showed that hadn’t significantly difference between with control group and all blood parameter were in normal range.
