Effects of Dietary Artemisia argyi Powder on Apparent Digestibility of Nutrients, Nitrogen Metabolism and Muscle Quality of Growing Meat Rabbits
摘要
Abstract
This experiment was conducted to study the effects of dietary Artemisia argyi powder on apparent digestibility of nutrients,nitrogen metabolism and muscle quality of growing meat rabbits.One hundred and sixty Hyla meat rabbits at 35 days of age and with similar body weight were randomly assigned to 4 groups with 40 replicates per group and one rabbit per replicate.Rabbits in the 4 groups were fed diets added with 0 (control group),3% (1% peanut vine and 2% wheat bran in the diet of control group were replaced),6% (3% peanut vine and 3% wheat bran in the diet of control group were replaced) and 9% (4% peanut vine and 5% wheat bran in the diet of control group were replaced) Artemisia argyi powder,respectively.The pre-test period lasted for 7 days,and the experimental period lasted for 30 days.The results showed that diet added with 3%,6% and 9% Artemisia argyi powder did not significantly affect the apparent digestibility of crude fiber (CF),neutral detergent fiber (NDF),acid detergent fiber (ADF),calcium (Ca) and phosphorus (P) (P>0.05),and the intake nitrogen,fecal nitrogen,urine nitrogen,retention nitrogen,nitrogen utilization and biological value of nitrogen were not significantly affected by diet added with 3%,6% and 9% Artemisia argyi powder (P>0.05).The apparent digestibility of crude protein (CP) and digestible nitrogen had no significant effects when diet added with 3% and 6% Artemisia argyi powder,but diet added with 9% Artemisia argyi powder significantly reduced the apparent digestibility of CP and digestible nitrogen (P<0.05).Compared with the control group,diet added with 6% and 9% Artemisia argyi powder significantly increased the apparent digestibility of ether extract (EE) (P<0.05).Diet added with 3%,6% and 9% Artemisia argyi powder significantly increased the drop loss of muscle (P<0.05),and had no significant effects on other muscle quality indexes (P>0.05),compared with the control group.According to the test indexes of this experiment,the addition of Artemisia argyi powder in the diet of growing meat rabbits should be no more than 6%.关键词
