Effects of Adding Nano-Chitosan on Productive Performance of Laying Hens

Abstract

he 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. 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 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. 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 experimental period was 12 weeks (23-34 weeks old). The egg laying rate, average egg weight, and feed conversion ratio of hens were not affected significantly by the experimental groups. Egg mass and feed intake were significantly decreased (P<0.05) for all treatments compared to the control group. Albumen height and Haugh unit were significantly increased in the T1 and T3 groups compared to the control group (P<0.05). Unsaturated fatty acids (ΣUSFA) were significantly increased in the T1 and T3 compared to the other groups (P<0.05). However, saturated fatty acids (ΣSFA) were significantly decreased in the T1 and T3 groups compared to the other groups (P<0.05). Malondialdehyde concentration was significantly decreased in the T1 and T3 groups (P<0.05) compared to the Co group. Immunoglobulin Y was significantly increased (P<0.05) in the T1 group followed by decreasing order in the T3 group. 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. These results concluded that both of OCh and ChNP have a positive effect on the productive performance of laying hens.

Influence of dietary chitosan supplementation on ovarian development and reproductive performance of New Zealand White rabbit does

“…Non-significantly in broiler chicken, confirming the antioxidant effects of chitosan (Jang et al, 2004;Je et al, 2006). Further, adding chitosan of 100 -200 mg/kg to the diets of adult farm animals can improve and support many reproductive traits, such as pregnancy and its outcomes, milk production, and egg production in dairy cows, swine, and laying hens (Wan et al, 2018;Hamady and Farroh, 2020).…”

Multifunctional Role of Chitosan in Farm Animals: A Comprehensive Review

“…In contrast, serum IgG, IgA, and IgM concentrations in Fengda-1 laying hens were not affected by chitosan treatment at 0.075 and 0.125 g/kg food (Xu et al, 2020). In addition, Hamady and Farroh (2020) found that chitosan treatments up to 200 mg/kg diet had no significant differences in IgA and IgM among all treatments, but IgY and intestinal…”

“…Thus, breeders should always ensure the efficiency of this event. Adding chitosan to the diets of adult farm animals can improve and support many reproductive events, such as pregnancy and its outcomes, milk production, and egg production in dairy cows, swine, and laying hens (Del Valle et al, 2017;Wan et al, 2018;Hamady and Farroh, 2020). The positive effects of chitosan on the reproductive performance of farm animals have been related to many modes of action.…”

“…In poultry, chitosan can improve egg production by laying hens (Yan et al, 2010), egg weight, yolk color, and egg yolk composition (Meng et al, 2010;Świątkiewicz et al, 2013;Hamady and Farroh, 2020). Kamal (2021) found that, using chitosan at doses of 0.2 and 0.4 g/kg diet was effective in enhancing sexual behavior and improving semen quality and reproductive efficiency in New Zealand white rabbit bucks.…”
