| Abstract |
Ninety laying hens of Gimmizah local strain at 32 weeks of age were used to study the effect of sorbitol on egg yolk cholesterol content and lipid metabolism. All hens were divided randomly into three equal groups (30 hens / group), the first group served as control and fed the commercial layer diet only, while the second and third groups were fed the commercial layer diet supplemented with 50 and 100 mg sorbitol/Kg of diet respectively.
The results indicated that the addition of sorbitol to the Gimmizah laying hen diets decreased (P <0.01) egg yolk and liver cholesterol (CH) ,and total lipid (TL) concentrations and serum triglyceride (TG), cholesterl (CH) and low density lipoprotein (LDL). Moreover, addition high level of sorbitol was increased (P < 0.01) serum high density lipoprotein (HDL) concentration, whereas serum glucose (GLC), glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) levels remained unchanged by the dietary sorbitol compared with the control group. Abdominal fat percentage was decreased (P < 0.01) when hens fed diet supplemented with sorbitol. While, no significant differences in excretion of bile volume of gall bladder and relative weights of liver, ovary and oviduct length were observed among groups during the experimental period. Body weight, feed intake, egg weight and egg production percentage were decreased (P < 0.01) especially with high level of sorbitol compared with the control group. No significant differences were detected in relative weights of yolk and albumin, egg shape index, yolk index and Haugh unit score, except shell weight and shell thickness which were decreased (P < 0.01) when hens fed diet supplemented with high level of sorbitol compared with the control group during the later weeks of production (38,42 and 46 weeks).
