Abstract


Herbs and their extracts as feed additives, has been more and more widely used in the livestock and poultry industry production, and due to its natural resistance, versatility, bi-regulation and resistant characteristics, herbal extract The material is the best alternative to antibiotics and other chemical synthetic drugs additives. This study the Hedysari crude polysaccharide and red clover total flavonoids on mice immune regulation and its impact on the three yellow broiler performance, for the development of livestock and poultry production performance, prevent and cure diseases herbal feed additives to lay the theoretical foundation. The results show that: 1 red Qi crude polysaccharide 200mg/kg, the Trifolium Flavnoids 200mg/kg, the Trifolium Flavnoids 400mg/kg dose group compared with the control group significantly enhanced mice carbon particles clearance capacity (p lt; 0.05) crude polysaccharides 400mg/kg; Hedysari, red clover total flavonoids 400mg/kg dose group can significantly increase mouse ear swelling (p lt; 0.05); the Trifolium Flavnoids 400mg/kg dose group significantly increased hemolysin HC50 (p lt; 0.05), Hedysari crude polysaccharide each dose group with the control group, no significant difference (p gt; 0.05); the Hedysari crude polysaccharide 400mg/kg significantly improve mouse spleen index (p lt; 0.05 ); the Trifolium Flavnoids 100mg/kg, 200mg/kg dose group very significantly increase the spleen index (p lt; 0.05). From the the three yellow broiler entire breeding cycle, Hedysari crude polysaccharide 200mg/kg the Trifolium Flavnoids 50 mg / kg dose group than in the control group significantly improved broiler daily gain (p lt; 0.05); Hedysari crude the polysaccharide 50mg/kg, Hedysari crude polysaccharide 100mg/kg dose group, red clover total flavonoids 25mg/kg dose can significantly improve the chicken protein content (p lt; 0.05), red clover total flavonoids 50mg/kg dose group significant moisture to keep the chicken (p lt; 0.05), each dose group the Hedysari crude polysaccharide reduced abdominal fat percentage showed a significant effect (p lt; 0.05); Hedysari crude polysaccharide 200mg/kg dose group significantly improved broiler spleen index (p lt; 0.05). The organ index tended to increase with increasing concentration of total flavonoids of red clover, but there was no significant difference (p gt; 0.05). 3. Of Trifolium Flavnoids 50mg/kg dose group group compared with the control group can significantly reduce the broiler heart and liver MDA content (p lt; 0.05); total flavonoids of red clover each dose group can significantly increase the liver SOD activity ( p lt; 0.05); Trifolium Flavnoids 25mg/kg dose group significantly improved liver GSH-Px activity (p lt; 0.05) Hedysari the crude polysaccharides 200mg/kg dose group can significantly improve the kidney GSH2Px activity (p lt ; 0.05). Both Chinese herbal medicine on broiler disease prevention effect in each experimental group broiler mortality remained between 4.17% -8.33%, far below the 29.47% and 16.67% of the experimental control group mortality rate of breeding farms, significantly reduce the occurrence of diseases of broiler and reduce mortality. Conclusion: 1. The crude polysaccharide right amount of Hedysari and red clover total flavonoids extract can enhance mouse non-specific immunity, cellular immunity and humoral immune function, and promote the development of immune organs. 2 Hedysari crude polysaccharide extract and red clover total flavonoids in a certain dose range can promote the growth and development of the broiler and immune organ, to speed up muscle tissue protein synthesis, and improve meat quality and improve the antioxidant capacity of broilers . 3. The Hedysari crude polysaccharide and red clover total flavonoids extract a certain role in the prevention of the occurrence of infectious diseases of broiler.
