Effects Of Compound Chinese Herbal Medicine Additives On Production Performance And Meat Quality Of Luhua Chicken

We used Luhua chickens as test animals to study the effect of compound Chinese herbal medicine additives on the production performance and meat quality.It aimed to provide a theoretical basis for the application of compound Chinese herbal medicine to increase the growth speed and improve the meat quality of Luhua chickens.In this test,640 healthy 1-day-old Luhua chickens were randomly selected to adopt a single-factor design scheme,and randomly divided into a control group and a test group,with 4 replicates in each group and 80 replicates in each replicate.The control group was fed with conventional diet,and the test group was added with 0.3% compound Chinese herbal medicine additive in the conventional diet,with a pre-feeding period of 10 days and a test period of 84 days.On the basis of this experiment,6,300 reed chickens were popularized and applied to study the effect of compound Chinese herbal medicine additives on the economic benefits of Luhua chicken.The results are as follows:1.Production performance: Compared with the control group,the final weight and average daily weight gain of the test group increased by 15.76%(P <0.01)and 17.01%(P <0.01),respectively,and the feed weight ratio decreased by 17.84%(P <0.01),Survival rate increased by 4.80%(P> 0.05).2.Serum biochemical indicators: Compared with the control group,serum triglycerides and blood glucose in the test group were significantly reduced by 13.86%(P <0.05)and 13.39%(P <0.05).3.Slaughter performance and meat quality traits: Compared with the control group,the slaughter rate and pectoral muscle rate of the test group increased by 5.05%(P <0.05)and 9.90%(P <0.05),abdominal fat rate decreased by 32.45%(P <0.05);the shear force,system hydraulic force,and drip loss of the pectoral muscle were reduced 23.70%(P <0.05),11.40%(P> 0.05),19.22%(P <0.05),the cooked meat rate increased by 3.28%(P> 0.05).The shear force,hydraulic force and drip loss of leg muscles were reduced by 21.83%(P <0.05),11.35%(P> 0.05)and 17.42%(P <0.05),respectively.4.Nutritional composition of leg muscles: Compared with the control group,unsaturated fatty acids,palmitoleic acid C16: 1n7,oleic acid C18: 1n9 c and linoleic acid C18: 2n6 c increased by 7.85%(P <0.05)and 29.53%(P <0.01),10.94%(P <0.01)and 12.14%(P <0.01);cholesterol decreased by 7.87%(P> 0.05);the ash content,vitamin B1,vitamin B6 and vitamin E content of leg muscles in the test group increased 16.67%(P <0.01),43.75%(P <0.01),11.29%(P <0.01)and 36.36%(P <0.01).5.The compound Chinese herbal medicine additive has a tendency to increase the expression of H-FABP m RNA in the chicken leg muscle of Luhua.Economic benefit: compared with the control group,the income of Luhua chicken in the experimental group increased by 7.79 yuan for each,and the benefit increased by 18.99%.Conclusion:1.Compound Chinese herbal medicine additives significantly improve the production performance of Luhua chicken,reduce the feed-to-meat ratio,and increase the economic benefits of Luhua chicken.2.Compound Chinese herbal medicine additives significantly reduce the blood sugar and triglyceride levels in the serum,significantly increase the content of various unsaturated fatty acids and 3 vitamins in the leg muscle of reed chicken,reduce the cholesterol level in the leg muscle,and improve the quality and quality of the reed chicken Tenderness.3.The expression level of H-FABP m RNA in Luhua chicken leg muscle has an upward trend,but the difference is not significant.
