Effects of Chitosan on Serum Lipid and Adipocytokine Contents of Laying Breeders
摘要
Abstract
This experiment was conducted to investigate the effects of chitosan with different supplemental lev-els on serum lipid and adipocytokine contents of laying breeders. Four hundred and fifty 26-week-old Hy-Line brown laying breeders were randomly assigned to 5 groups with 6 replicates in each group and each replicate contained 15 chickens. Chickens in 5 groups were fed experimental diets containing 0 ( control) , 250, 500, 1000 and 2000 mg/kg chitosan, respectively. The trial lasted for 56 days. The results showed as follows:compared with control group, diets supplemented with 250, 500, 1000 and 2000 mg/kg chitosan could re-duce the contents of total cholesterol ( TC ) , low density lipoprotein cholesterol ( LDL-C ) , free fatty acids ( FFA) in serum and the content of FFA in liver of laying breeders in different degrees on the days 28 and 56 of the experiment. On the day 28 of experiment, compared with control group, diets supplemented with 250, 500 and 1000 mg/kg chitosan could significantly reduce the serum triglyceride (TG) content (P≤0.05), supplemented with 500 mg/kg chitosan could significantly reduce the serum very low density lipoprotein ( VLDL) content ( P≤0.05) , supplemented with 250, 500, 1000 and 2000 mg/kg chitosan could signifi-cantly reduce the serum leptin ( LEP) content ( P≤0.05) , and supplemented with 500 mg/kg chitosan could significantly increase the serum high density lipoprotein cholesterol ( HDL-C) content ( P≤0.05) . On the days 28 and 56 of experiment, the serum TC content of laying breeders showed a significant linear decreasing rela-tionship with the chitosan supplemental level (P<0.01). On the day 28 of experiment, the serum TG (P<0.01), HDL-C (P<0.01), FFA (P=0.04) and VLDL contents (P<0.01) showed a significant quadratic curve relationship with chitosan supplemental level, and when chitosan supplemental level was 652. 56 to 967.18 mg/kg, it could better regulate the above indexes. It is concluded that the supplementation of chitosan can improve the healthy level of lipid metabolism in laying breeders, and the effects of chitosan on the contents of lipids in serum and the content of FFA in liver are related to its supplemental level.关键词
