Problems solved by technology

Due to the health care effect of selenium, many farmers currently use selenium-enriched feed to feed native chickens to improve the nutritional value of native chickens and eggs; but most of these selenium-enriched feeds are directly added to the feed with elemental selenium and selenium salts , due to the high price of elemental selenium or selenium salts, the cost of breeding increases, which seriously affects the economic benefits of farmers, or these selenium-enriched feeds are widely used in various poultry and are not designed according to the growth characteristics of native chickens. Slower growth and lower uptake of selenium
For example, the patent application number is 201711174926.2, which discloses a production method of selenium-enriched chicken feed and selenium-enriched eggs. Lemongrass, licorice, pine needle powder, and additives are used as raw materials to make selenium-enriched chicken feed. The selenium-enriched chicken feed fed to laying hens can effectively improve the laying rate of laying hens and the western content of eggs. However, this selenium-enriched feed is used in soil Chickens have little effect on promoting the metabolism and digestion of native chickens, and the growth rate of native chickens is slow, which also affects the absorption of selenium by native chickens

Abstract

The invention belongs to the technical field of cultivation and particularly relates to special selenium-enriched feed for native chickens. The selenium-enriched feed is prepared from corns, rice bran, rapeseed cakes, bean dregs, purple sweet potatoes, ryegrass, lotus roots, sweet potato vines, plantain herb, caulis spatholobi, squeezed pulp grass and complex microbial inoculants by the steps of mixing and fermenting various raw materials or raw material extracts in a segmented fermentation mode. The special selenium-enriched feed for the native chickens can effectively increase the content ofselenium in chicken and eggs of the native chickens; furthermore, nutritional components in the feed are easy to transform and absorb, food intake of the native chickens can be promoted, the growth of the native chickens can be accelerated and the growth cycle can be shortened; meanwhile, the immunity of the native chickens can be enhanced; the raw material sources are wide and the preparation cost is low.

Description

technical field [0001] The invention belongs to the technical field of breeding, in particular to a special selenium-enriched feed for native chickens. Background technique [0002] Native chicken, also known as grass chicken and stupid chicken, is a kind of poultry. It refers to broiler chickens raised in mountains, forests and orchards. It has the characteristics of resistance to rough feeding, strong nesting ability and strong disease resistance. Compared with caged laying hens and broilers, native chickens have higher nutritional value of eggs, and the taste of chicken is more delicious; and because most of them are raised in forests or orchards, they are fed whole grains and freely forage for insects and weeds. Drinking dew, strictly restricting the use of hormones, feed additives, etc., is closer to the requirements of green environmental protection, so it is more favored by consumers. [0003] Selenium is an important component of antioxidant enzymes such as glutathi...
