Abstract

This study was carried out to evaluate the effect of Chitozinc and Chitonal on performance of laying hens. The studied parameters were feed intake, egg production %, egg weight, egg mass and feed conversion ratio as well as lipid profile in egg yolk. Sixty Lohmann Brown laying hens (34 weeks age) were assigned to three groups, each of 20 hens. The 1st group (control) was fed on basal diet only, the 2nd group was fed on basal diet +1ml of Chitonal /liter drinking water and the 3rd group was fed on basal diet + 200 gm. Chitozinc /ton. All groups were kept under observation for 45 days and egg production (EP) % , Feed intake FI (g/hen), average egg weight (EWT) in (g) , egg mass production (g/hen/day) and feed conversion ratio FCR (Kg feed/Kg egg) were calculated along the experiment. Eggs were collected from each group three days before the end of the experiment for biochemical analysis of fat content in egg yolk. The results showed that addition of 1ml of Chitonal /liter to drinking water improved egg production (EP) % , Feed intake FI (g/hen), average egg weight (EWT), egg mass production (g/hen/day) and feed conversion ratio FCR (Kg feed/Kg egg) , and a significant decrease in total lipid, total cholesterol, low density lipoprotein (LDL) in egg yolk. A significant decrease in very low density lipoprotein (VLDL), triglyceride, and atherogenic index (AI) and a significant increase in high density lipoprotein (HDL) in egg yolk in both 2nd and 3rd groups was reported. The results clarified that, the use of Chitozinc and Chitonal improved the performance and lipid profile in egg yolk of laying hens.
