Good breeding environment-ensuring method for raising laying hens

Abstract

The present invention discloses a good breeding environment-ensuring method for raising laying hens. A viable probiotics preparation and a micro-ecological preparation are added in drinking water of the laying hens and can maintain micro-ecological balance in the intestinal tract of the laying hens, probiotics enter the digestive tract quickly, become dominant population of microorganisms in the intestinal tract, seize colonization of attachment sites, produce micro-organism-inhibiting substances and organic acids through growth and metabolism, reduce intestinal PH value, create an intestinalanaerobic environment, inhibit growth of other harmful pathogenic microorganisms, repair and maintain balance of microbial flora in the intestinal tract, achieve purposes of preventing diseases and promoting growth, and also have effects of promoting digestion and absorption, nucleic acid is added to feeds to reduce release of skatole and indole during a breeding process of the laying hens and reduce feces odor, and padding with candida krusei can accelerate degradation of ammonia nitrogen in chicken manure, further reduce odor of the chicken manure, and ensure a good breeding environment.

Description

technical field [0001] The invention relates to the field of new technologies for raising poultry, in particular to a method for raising laying hens that can ensure a good breeding environment. Background technique [0002] Since the 1980s, my country's poultry industry has developed very rapidly, and the development of chicken farms has gradually moved towards scale, intensification and factoryization, and chicken farms with more than 100,000 chickens have sprung up like mushrooms after rain. With the construction of large-scale chicken farms, a large amount of feces and harmful gases emitted by chickens have continuously aggravated environmental pollution, which not only seriously affects the health and production performance of chickens, but also poses a great threat to human health. Chickens have a short digestive tract and low digestibility. Usually, 20% to 25% of the nutrients in the feed are not digested and absorbed by the body, and they are excreted in feces. Labor...

Problems solved by technology

At the same time, due to the lack of digestive enzymes in the body, laying hens, especially chicks, have a low ability to digest nutrients in the feed, especially phytic acid. Not only can they not fully utilize the phosphorus contained in phytic acid, but phytic acid can also Can complex other nutrients to become anti-nutritional factors, hindering the digestion and absorption of other nutrients

When the chicken manure containing these nitrogen and phosphorus enters the soil, it will be converted into nitrate and phosphate, leading to soil salinization. If the content is too high, the land will be compacted and lose its production value. Not only that, it may also cause groundwater pollution, making the water The content of nitrate nitrogen in the water increases, and the total number of bacteria in the water exceeds the standard

This kind of untreated chicken manure entering the river will lead to eutrophication of the water body, a large number of mosquitoes, flies and other insects, and excessive reproduction of algae and other aquatic plants, which will reduce the dissolved oxygen in the water, and aquatic animals such as fish and shrimp will die due to lack of oxygen. death, resulting in the corruption of water bodies

Moreover, chicken manure will emit harmful gases with foul smell, which makes the breeding environment very bad. Therefore, regulating the discharge of nitrogen and phosphorus in intensive chicken farms has become a technical problem to be solved urgently in the process of healthy chicken breeding. The research hotspot of platoon has become the key link to improve the efficiency of raising chickens
