Technical Field
The invention relates to the technical field of ecological breeding, in particular to an under-forest ecological breeding method for Guangxi partridge broiler chickens.
Background
Guangxi Ma chicken (Guangxi Partridge chicken) is called Lingshan Xiang chicken in the mountain county and Lidang chicken in the mountain county, and belongs to a dual-purpose local variety. The origin and central production area of Guangxi Ma chicken are Guangxi Zhuang nationality autonomous region Lingshan county, Pubei county, Hepu county, Yangxi county, City of defense, Mashan county and Duan county. The Guangxi Ma chicken has strong adaptability, tender meat quality, fragrant smell, relatively balanced amino acids in the chicken and high nutritive value for human body.
With the continuous development of the chicken industry, people often use antibiotics to inhibit or kill harmful microorganisms in the digestive tract of chickens so as to improve the production performance of the chickens, but the addition of the antibiotics into the feed has side effects, such as dysbacteriosis in the chickens, drug resistance, influence of drug residues on human health and the like, and the antibiotics are increasingly attracted by the world, and many countries have increasingly prohibited the use of the antibiotics as feed additives. The modern breeding industry increasingly advocates ecological breeding, which applies ecological technical measures to improve the breeding environment, puts in pollution-free feed, does not fertilize and sprinkle pesticide, and produces pollution-free green food and organic food.
Ecological breeding usually adopts microecologics to regulate in-vivo flora and promote substance circulation so as to obtain good economic benefit. However, in the ecological breeding process of the Guangxi partridge, the breeding environment of the Guangxi partridge is difficult to control, and the health of the Guangxi partridge is affected due to the deterioration of the breeding environment, so that the growth of the Guangxi partridge is inhibited, and the feed conversion rate of the Guangxi partridge is reduced.
