Technical Field
The invention relates to the technical field of chicken feed, in particular to a feed additive and feed capable of prolonging the laying period of laying hens.
Background
China is a big country for laying hen breeding, the annual stock of commercial laying hens is over 13 hundred million, and 3000 million tons of fresh eggs are laid every year. With the aging of organisms in the breeding process of laying hens, the organism function of the laying hens in the later period of laying is deteriorated, the digestive metabolism level is reduced, the laying rate begins to be reduced, the egg quality also begins to be deteriorated, the problems of egg quality such as broken eggs, soft eggs and the like in the later period of laying are caused to be frequent, and when the egg laying economic benefit of laying hens is close to the cost required by laying eggs, the laying hens are eliminated. According to the invention, the functional substances are added to improve the production performance and egg quality of the laying hens in the later egg-laying period, so that the egg-laying period of the laying hens is prolonged, and the economic value of the laying hens is increased.
The trace element selenium is a nutrient element necessary for animals and human bodies, is an essential component of functions of important antioxidant enzyme and selenium-containing protein, and has biological functions of resisting oxidation, resisting stress, improving the immunity of the organism and the like. A plurality of research results show that proper amount of selenium supplement can improve the anti-oxidation stress capability of the laying hen organism, improve the quality of animal products, improve the immune function and the animal production performance, selenium taken by the laying hen can be converted into the laying hen organism and the products thereof through the biological conversion, the utilization efficiency of organic selenium is higher than that of inorganic selenium, the stable yeast selenium product can be obtained only by the industrial production of part of large-scale enterprises by using the common yeast selenium product of the organic selenium, and the cost is higher.
The probiotics can be propagated and grown in the intestinal tracts of animals, secrete digestive enzymes to promote the absorption and metabolism of organisms to nutrient substances, maintain the normal flora balance of the intestinal tracts by inhibiting the growth and the propagation of harmful microorganisms in the intestinal tracts, and improve the immunocompetence of the animals through the intestinal tract immunity.
The Chinese herbal medicine contains various biological active substances and nutrient components, and the Chinese herbal medicine for feeding the bred animals can improve the oxidation resistance of the organisms, improve the immunity of the organisms and reduce the morbidity of the laying hens, but the types and the proportions of different Chinese herbal medicines have different effects on the organisms of the animals.
Disclosure of Invention
In view of the above, the invention provides a feed additive and feed capable of prolonging the laying period of a laying hen, which are prepared by compounding selenium-rich vegetable powder and Chinese herbal medicines and matching with a proper amount of probiotics, so that the laying period of the laying hen is effectively prolonged.
In order to achieve the purpose, the invention adopts the following technical scheme:
a feed additive capable of prolonging the laying period of a laying hen is prepared from raw materials of selenium-rich vegetable powder, compound Chinese herbal medicine powder, probiotic powder and a carrier, wherein the compound Chinese herbal medicine powder is prepared from 10-20% of codonopsis pilosula, 10-20% of Chinese angelica, 10-20% of eucommia ulmoides, 10-30% of astragalus membranaceus, 10-25% of bighead atractylodes rhizome and 10-35% of poria cocos in percentage by weight.
Preferably, the carrier is one or more of rice hull powder, glucose, brown sugar, stone powder and zeolite powder
Preferably, the feed additive consists of 30-60% of vegetable powder, 1-5% of probiotic powder, 20-50% of composite Chinese herbal medicine powder and 10-35% of carrier according to weight ratio.
Preferably, the strain of the probiotic powder is bacillus subtilis or/and lactobacillus plantarum. The bacillus subtilis and the lactobacillus plantarum can assist the laying hens in decomposing macromolecular nutrient substances and promote digestive absorption of feed by digestive tracts so as to achieve the purpose of improving the utilization rate of the feed.
More preferably, the probiotic strains are respectively cultured in a fermentation tank and then concentrated, and freeze-dried at a low temperature to prepare the bacterial powder, wherein the viable count in the bacterial powder is 1-5 multiplied by 1011CFU/g, and then proportioning different bacterial powder according to the requirement.
Preferably, the total selenium content of the selenium-rich vegetable powder is more than or equal to 1500mg/kg, and the organic selenium content is more than or equal to 96%; more preferably, the selenium-rich vegetable powder comprises the following raw materials of 10-35 wt% of selenium-rich broccoli, 30-60 wt% of selenium-rich capsella bursa-pastoris and 10-35 wt% of selenium-rich cabbage.
More preferably, the preparation process of the selenium-rich vegetable powder specifically comprises the following steps: cleaning the raw materials, cutting the raw materials to 2-5 cm, drying the raw materials by hot air until the moisture content is less than or equal to 10%, and crushing the raw materials into 40-60-mesh plant powder.
Preferably, the preparation process of the compound Chinese herbal medicine powder is as follows: weighing the raw materials in proportion, chopping, mixing according to the weight ratio of the raw materials to the liquid medicine of 1: 3-5, boiling with strong fire, slightly boiling for 30-40 min, drying and crushing.
In a second aspect of the present invention, there is provided a feed containing the feed additive, preferably, the feed additive is added in an amount of 0.04 to 0.06% by weight.
The invention has the beneficial effects that: the main components of the feed additive are natural plants, so that the feed additive is easy to obtain, low in cost, green, environment-friendly and high in safety; through the compatibility of the selenium-rich plants, the Chinese herbal medicine composition and the probiotics, the organic selenium, the probiotics, the polysaccharide substances and the immune enhancement factors rich in the Chinese herbal medicines in the vegetable powder can jointly improve the immunity of the laying hens, reduce the morbidity of the laying hens, and reduce the risk of elimination due to diseases, so that the laying rate and the quality of eggs of the laying hens are synergistically improved, and the laying period of the laying hens is effectively prolonged.
