Effects of Grazing on Interforest Grassland on Carcass Traits, Egg and Meat Qualities of Beijing Fatty Chicken
摘要
Abstract
In order to study the effect of grazing on interforest grassland on carcass traits, egg and meat qualities of Beijing fatty chicken,chicory (Cichorium intybus) and alfalfa (Medicago sativa) (1∶1)were planted in chestnut orchard to establish the mixed artificial grassland for rotationally grazing Beijing fatty chicken. The carcass traits and the nutrition content of breast muscle,leg muscle and eggs of Beijng fatty chicken were measured. The results showed that compared with control(Beijing fatty chicken were grazed on the bare land in chestnut orchard) ,all indexes of carcass traits of Beijing fatty chicken rotationally gra-zing on artificial grassland significantly improved. Leg muscle weight,pectoral muscle weight and abdominal fat weight significantly increased by 22. 25%,15. 33% and 108. 71%. Leg muscle rate,pectoral muscle rate and abdominal fat rate increased by 19. 23%,12. 00% and 100. 00%. The content of crude ash and the es-sential amino acid of leg muscle of grazing Beijing fatty chicken on the artificial grassland significantly in-creased by 23. 42% and 20. 89%. Calcium content of breast muscle significantly increased by 29. 99%,and the crude fat and crude ash content of breast muscle significantly decreased 15. 69% and 33. 02%. The egg yolk cholesterol significantly decreased by 14. 58%. With reducing supplementary feeding amount by 15%, the feed weight ratio significantly decreased by 17. 65% and 15. 94%. Compared with control at age of 8—17 weeks and age of 18—25 weeks. Thus,Beijing fatty chicken grazing on orchard with inter-planting grasses could increase its carcass traits,egg and meat qualities and productivity benefit.关键词
