Technical Field
The invention relates to the technical field of production of selenium-rich feed additives, in particular to an additive for improving selenium-rich content of poultry eggs, a preparation process and application of the additive in laying hen feeding.
Background
The existence mode of selenium in the nature is divided into two types, namely inorganic selenium and organic selenium: inorganic selenium generally refers to sodium selenite and sodium selenate, and is obtained from by-products of metal mineral reserves; the latter is formed by combining selenium with amino acids through biotransformation, generally in the form of selenomethionine. The selenium-rich pig meat, beef, mutton, milk, poultry meat and eggs and the like produced by pigs, cattle, sheep and poultry bred by the selenium-rich feed contain animal selenium protein which is easy to be absorbed by the human body, and are the best selenium-supplementing functional food for human in the world at present; the livestock and poultry can safely absorb and convert the selenium only by converting feed plants into organic selenoprotein, but most of the feed plants have low organic conversion rate of the selenium, are only green manure, have strong selenium enrichment capacity of the astragalus sinicus serving as the feed, have high organic conversion degree, and are ideal livestock and poultry selenium-rich feed and feed additives.
Therefore, people often add milk vetch as a selenium-rich additive into the feed of livestock and poultry to improve the selenium-rich content in meat and eggs of the livestock and poultry, however, the mode of only adding milk vetch into the feed is single, the selenium-rich effect is poor, and the selenium-rich additive in the feed needs to be further researched and optimized. For example, in the prior art, in a method for producing pollution-free selenium-rich ducks and duck eggs by using a secondary selenium-rich milk vetch conversion technology with patent number CN102067951A, high-yield selenium-rich milk vetch is disclosed as one of the components of the compound feed, the selenium protein content in the ducks and duck eggs is rich and safe and nutritional for eating after the secondary selenium conversion of the milk vetch and the domestic ducks, the selenium content of finished eggs is qualified after detection, and is higher than the control by more than 50% (500 micrograms/kg) through selenium supplement, but it can be seen that the selenium-rich additive only adds the milk vetch, and the selenium content is higher than the control by 50%, and a space for further improvement is provided.
Disclosure of Invention
Aiming at the problems in the prior art, the invention aims to provide the additive for improving the selenium-rich content of the poultry eggs, which has simple components, low production cost and good selenium-rich effect. In order to realize the purpose of the invention, the following technical scheme is adopted:
an additive for improving selenium-rich content of poultry eggs comprises selenium-rich milk vetch powder, wherein the content of the selenium-rich milk vetch powder in the additive is 10-30%, the granularity of the selenium-rich milk vetch powder is 60-160 meshes, the water content of the selenium-rich milk vetch powder is 5% -9%, and the processing mode of the selenium-rich milk vetch powder mainly comprises the following steps:
(01) sowing: sowing the astragalus sinicus seeds in a proper season, wherein the ground cannot be soaked with water during sowing, but the ground is kept moist;
(02) fertilizing: under the conventional management and cultivation, selenium fertilizer is sprayed twice in the growth process of the astragalus sinicus, namely the jointing stage and the flowering and bud stage of the astragalus sinicus, and the amount of the selenium fertilizer sprayed twice is 200-230 mL/mu;
(03) harvesting: after the milk vetch in the step (02) is ripe, harvesting two thirds of the milk vetch on the ground, collecting and airing, and drying at 60-100 ℃ to constant weight to obtain dry milk vetch;
(04) crushing: and (3) putting the dry-base astragalus sinicus obtained in the step (03) into a grinder to be ground until dry-base crop powder with proper granularity is obtained.
Preferably, the selenium-enriched milk powder comprises, by percentage, 20-30% of selenium-enriched corn flour, 10-20% of selenium-enriched soybean flour and 20-60% of selenium-enriched common leafflower herb powder, and the particle size and the water content of the selenium-enriched corn flour, the selenium-enriched soybean flour and the selenium-enriched common leafflower herb powder are the same as those of the selenium-enriched milk vetch powder.
Preferably, the processing mode of the selenium-rich corn flour, the selenium-rich soybean flour and the selenium-rich defoliant powder mainly comprises the following steps:
(a) sowing: in proper seasons, seeds of corn, soybean and selenium-rich herbivore are respectively sowed in blocks;
(b) fertilizing: under the conventional management and cultivation, respectively spraying selenium fertilizer to each land planted with the corns, the soybeans and the selenium-rich herbivores in the step (a) at different periods so as to improve the conversion rate of plant selenoprotein in the additive and obtain selenium-rich crops;
(c) harvesting: after the crops in the step (b) are mature, respectively harvesting, collecting and airing, and drying at 60-100 ℃ to constant weight to obtain dry basis crops;
(d) crushing: and (c) putting each dry crop obtained in the step (c) into a crusher to be crushed until dry crop powder with proper granularity is obtained.
Preferably, the selenium content in the selenium fertilizer is 5-8g/100 mL.
Preferably, the selenium fertilizer is required to be sprayed to the corn twice, namely the jointing stage of the corn and the tassel-drawing stage of the corn, and the selenium fertilizer is sprayed to the corn twice in an amount of 120 mL/mu and 150 mL/mu respectively in an amount of 100-; the selenium fertilizer is required to be sprayed to the soybeans once, the selenium fertilizer spraying time is in the flowering and pod bearing period of the soybeans, and the selenium fertilizer spraying amount is 120-150 mL/mu; the selenium-rich leaf-eating grass is harvested 4-5 times a year, the selenium fertilizer is sprayed once 10 days before each harvest, and the amount of the sprayed selenium fertilizer is 100-120 mL/mu.
