Effects of Dietary Crude Fiber Level and Grit on Serum Lipometabolism Indices, Slaughter Performance and Meat Quality of Sichuan White Geese
摘要
Abstract
This study investigated the effects of dietary crude fiber ( CF) and grit on serum lipometabolism in?dices, slaughter performance and meat quality of Sichuan white geese during 22 to 70 days of age. The trial used two factorial design consisting of with or without grit addition, and dietary CF levels were 4.0%, 7.0%and 10.0%, respectively. A total of 648 twenty?two?day?old male Sichuan white geese with similar body weight were randomly allotted to 6 treatments with 6 replicates per treatment and 18 geese per replicate. The ex?periment lasted for 48 days. The results showed as follows: 1) dietary CF level significantly affected the con?tents of glucose, total cholesterol and high?density lipoprotein in serum of Sichuan white geese at 49 days of age ( P＜0.05) , and significantly affected the contents of glucose, triglyceride, total cholesterol and high?den?sity lipoprotein in serum of Sichuan white geese at 70 days of age ( P＜0.05). Dietary grit significantly affected the contents of glucose and triglyceride in serum of Sichuan white geese at 49 and 70 days of age ( P＜0.05). 2) Dietary CF level and grit had no significant effect on the slaughter performance and meat quality of Sichuan white geese at 70 days of age ( P＞0.05). In conclusion, increasing dietary CF level can downgrade serum lipid content, and grit addition can increase some serum lipometabolism indices.[ Chinese Journal of Animal Nutri?tion, 2019, 31(9) :4052?4060]关键词
