Abstract:

In order to study the latest progress of nutriton and feed researches in Yellow-feathered broilers,provide some references,for the safety and efficiency of breeding in Yellow-feathered broilers industry,the authors consulted and summarized the domestic and foreign literature on feed nutrition of Yellow-feathered broilers from 2017 to 2018,mainly reviewed the nutrition requirements of Yellow-feathered broilers,technology of additive application,technology of the safe and efficient use of unconventional feed resources and the evaluation for the nutritive value of feed ingredients.The following points should be paid attention to the application and research:The contents of mineral elements and vitamins in feed materials should be ascertained in order to reduce the waste of vitamins and mineral elements.Chinese herbal medicine had many active ingredients such as polysaccharides,alkaloids,saponins,and organic acids.It was suggested to combine Chinese herbal medicine with different functions in a reasonable way.Probiotics additive was an effective and green additive for Yellow-feathered broiler chickens,in which Bacillus and yeast were effective,and the combination of two probiotics was more effective.In general,the efficient breeding techniques of Yellow-feathered broilers still should be developed.The utilization rate could be improved by improving the production process of plant feed raw materials.It was a trend to develop new animal protein raw materials.Insect animal protein such as fly maggot and black soldier fly had the advantages of safety,environmental protection,and which was the preferred choice of new animal protein feed materials.In general,the efficient breeding technology of Yellow-feathered broiler needs to be further improved,it included the following aspects:perfecting the breeding standards of Yellow-feathered broiler and breeding chickens;More extensive researches on the safe and efficient use of feed resources of Yellow-feathered broiler chickens;Study on the effects of maternal nutrition on the offspring of Yellow-feathered broiler chickens.

Key words: Yellow-feathered broilers; feed nutrition; research progress
