Problems solved by technology

[0007] (2) Reduced immunity of the body: the variability of animal immunity is affected by seasonal factors, environmental factors, and stress factors
[0008] (3) The content of harmful gases is high and the oxygen content is relatively low, which will cause the chickens to live in an oxygen-deficient environment for a long time, manifested as listlessness, loss of appetite, physical decline, reduced productivity, and weakened resistance to diseases. Very susceptible to some infectious diseases
[0016] (5) Hazards: small body weight, low survival rate, high mortality rate, low feed conversion rate, high drug cost, etc., resulting in low economic benefits

Embodiment 1

[0034] Example 1: Harmful gases in the chicken house include ammonia, hydrogen sulfide, indole, etc., which are manifested as ammonia, fishy and foul smells. The ammonia smell is mainly due to the relatively high protein content caused by low feed energy, or a variety of The decrease in feed conversion rate caused by the cause decomposes urate, an intermediate product of protein, and ammonia gas is the most harmful to chickens. Ammonia gas can enter the trachea through the breath of the chicken, dissolve into the water on the surface of the trachea, and pass through the trachea. A layer of ammonia water is formed on the surface, and over time, it will stimulate the trachea to appear damaged ulcers, and pathogenic microorganisms will take advantage of the gap, increasing the incidence of chicken flocks. The fishy smell comes from the shedding of the intestinal mucosa caused by intestinal diseases such as coccidia, enteritis, and E. coli, and the bad smell is caused by the deteri...

Embodiment 2

[0035] Example 2: When chickens are infected with chicken diseases, antibiotics are used in large quantities, or stress will lead to intestinal flora imbalance, which will not only cause a decrease in feed conversion rate, but also stimulate some intestinal diseases, thereby producing a variety of harmful gases. Especially in winter, the metabolizable energy level of the feed is low, the energy-to-egg ratio is out of balance, protein will be converted into energy, and the intermediate product urate will release ammonia. In winter, the focus is on heat preservation, and the ventilation is insufficient, resulting in an increase in the ammonia concentration in the chicken house.

[0036]As environmental protection policies become more and more stringent, the ammonia requirements for chicken coops are getting higher and higher. Moreover, in autumn and winter, there is no time to do enough ventilation and excrement, and the ammonia in the chicken house cannot be effectively solved....

Embodiment 3

[0037] Example 3: To reduce the ammonia content in the chicken house, it is ensured by measures such as nutritional balance, suitable protein, high digestion and utilization rate, and healthy intestinal environment conditions. Through the research on reducing the protein of laying hens and related supporting measures, the cost of feed can be greatly saved, the egg production rate can be increased, and the emission of nitrogen can be reduced, thereby increasing the economic benefits of farmers. Utilizing the ideal protein-energy ratio of laying hens, adopting digestible amino acid and net energy system and other technologies to formulate the laying hen diet with corn and soybean meal as the main raw materials, the formulated feed is comprehensive, balanced and stable in nutrition, and can reduce the nitrogen in the feed Emissions, while satisfying the growth and development of laying hens, to maximize the genetic potential. This project aims to reduce the protein content in the...

Abstract

The invention discloses a preparation method of ration for reducing content of ammonia in chicken manure. The preparation method comprises the following steps that S1, good-quality feed raw materialswhich are free from mildew and a feed additive for improving the utilization efficacy of a feed are selected; S2, after material preparation is completed, nutrient requirement parameters of egg-layinghens under different environmental conditions are obtained; S3, an ideal amino acid model is adopted, so that the protein content is reduced, the ammonia generation is reduced and the attack rate ofthe egg-laying hens is reduced; and S4, the production technology mainly comprises the steps of removing impurities in the raw materials, performing crushing and performing mixing. Main technique indexes comprise uniform degree of the mixed feed, and control of the granule size of the feed. An ideal protein energy proportion is utilized, techniques of digestible amino acids, a net energy system and the like are adopted for preparation, and corn and soybean meal are used as main raw materials, so that the ration for the egg-laying hens is prepared. The prepared feed is comprehensive, balanced and stable in nutrients, can reduce the nitrogen discharge of the feed, besides, can meet requirements for growth and development of the egg-laying hens, and can exert the maximum heredity potential.

Description

technical field [0001] The invention relates to the technical field of biology and new medicine, in particular to a method for preparing a ration for reducing the ammonia content of chicken manure. Background technique [0002] Ammonia is important to life on Earth and is an important ingredient in many foods and fertilizers. Ammonia is also a direct or indirect constituent of all medicines. Ammonia has a wide range of uses, but it also has dangerous properties such as corrosiveness. Because ammonia has a wide range of uses, ammonia is one of the most produced inorganic compounds in the world, and more than 80% of ammonia is used to make fertilizers. [0003] The ammonia in the chicken house is mainly produced after the nitrogen-containing organic matter in the manure is fermented and decomposed by bacteria. It is highly irritating, especially to mucous membranes, which often leads to hyperemia and edema of chicken conjunctiva and upper respiratory tract mucous membranes,...
