![]() Total bacterial count, including Lactobacillus count in the intestine was significantly increased (P < 0.05) in the T1 and T3 groups compared to the other groups. Immunoglobulin Y was significantly increased (P<0.05) in the T1 group followed by decreasing order in the T3 group. Malondialdehyde concentration was significantly decreased in the T1 and T3 groups (P<0.05) compared to the Co group. However, saturated fatty acids (ΣSFA) were significantly decreased in the T1 and T3 groups compared to the other groups (P<0.05). Unsaturated fatty acids (ΣUSFA) were significantly increased in the T1 and T3 compared to the other groups (P<0.05). Albumen height and Haugh unit were significantly increased in the T1 and T3 groups compared to the control group (P<0.05). Egg mass and feed intake were significantly decreased (P<0.05) for all treatments compared to the control group. The egg laying rate, average egg weight, and feed conversion ratio of hens were not affected significantly by the experimental groups. ![]() The experimental period was 12 weeks (23-34 weeks old). The control group (Co) were fed the basal diet without the supplement, while birds in the treatment groups T 1, T 2, and T 3 were fed the basal diet supplemented with 200 mg OCh/kg diet, 50 mg ChNP/kg diet, and 200 mg ChNP /kg diet, respectively. ![]() The control (Co) group, T1 group, and T2 group were fed 0.0 mg/kg diet, 150 mg/kg diet and 300 mg/kg diet, respectively. ![]() A total of 96 hens of Bábolna TETRA-SL at 23 weeks of age were randomly assigned into 4 experimental groups with three replicates each. The present study evaluated the effects different forms of chitosan (ordinary chitosan " OCh" and chitosan nanoparticles " ChNP ") as a dietary supplementation on egg production, egg quality, yolk egg composition, blood serum traits, and intestinal bacteria. ![]()
