Selenium-rich fine fodder for feeding cattle and sheep and using method thereof

Abstract

The invention discloses selenium-rich fine fodder for feeding cattle and sheep and a using method thereof. The selenium-rich fine fodder comprises rice bran having a selenium content of 1-30 [mu]g / g and rice straw powder having a selenium content of 2-50 [mu]g / g. The weight ratio of the rice straw to the rice bran is 0.5-1:7-9. The selenium-containing rice bran and the selenium-containing rice straw are obtained by fertilizing a selenium fertilizer during the culturing process of rice. The selenium relates to organic selenium which is mainly selenium-substituted amino acids. According to the fine fodder and the using method thereof, animal absorption is achieved in a manner of the organic selenium, thus solving the problems of animal poisoning and low absorption.

Description

technical field

[0001] The invention relates to the technical field of animal husbandry, in particular to the field of feed, in particular to a selenium-enriched concentrate for feeding cattle and sheep and a use method thereof. Background technique

[0002] Selenium is not only an essential trace element for humans, but also for animals. Due to the toxicity of selenium and the low utilization rate of sodium selenite, the direct addition of sodium selenite to feed may cause excessive animal death and environmental pollution, thus limiting the application of inorganic selenium in feed. In 1984, the FDA had lowered the upper limit of inorganic selenium to 0.1 mg / kg, and organic selenium may be a safe and efficient selenium additive. In recent years, people have tried to add plant-transformed selenium as a feed additive, and achieved good results. Such as Hubei Sheng Se Biological Technology Co., Ltd. [Patent No.: CN201210502690] applied for an invention patent through the ap...

Embodiment 1

[0011] 1. Preparation of selenium-enriched concentrate: Select rice bran and straw, the by-products of rice that are fertilized with selenium during the planting process. The laboratory has measured that the selenium content of rice bran is 10 μg / g, and the selenium content of rice straw is 20 μg / g. More than 99% of selenium is selenoamino acid, and the selenium-enriched rice bran and selenium-enriched straw are dried and ultrafinely pulverized, and mixed and granulated according to 1:7 to prepare selenium-enriched concentrate.

[0012] 2. Application of selenium-enriched concentrate: mix the prepared selenium-enriched concentrate with the base material at a weight ratio of 1:10 to form a full-price feed, and feed it to beef cattle. After feeding for one and a half months, slaughter and send for inspection, and test in the laboratory The selenium content in the meat is 324 micrograms / kg, the selenium content in the liver is 545 micrograms / kg, and the selenium content in the kid...

[0017] 1. Preparation of selenium-enriched concentrate: rice bran and straw, the by-products of rice fertilized with selenium fertilizer during planting, were selected. The laboratory measured that the selenium content of rice bran was 3 μg / g, and the selenium content of rice straw was 5 μg / g. More than 99% of selenium is selenoamino acid, and the selenium-enriched rice bran and selenium-enriched straw are dried and ultrafinely pulverized, and mixed and granulated at a ratio of 1:15 to prepare selenium-enriched concentrate.

[0018] 2. Application of selenium-enriched concentrate: mix the prepared selenium-enriched concentrate with base material at a weight ratio of 1:5 to form a full-price feed, and feed it to beef cattle. After 3 months of feeding, slaughter and send for inspection, and laboratory testing The selenium content in the meat is 214 micrograms / kg, the selenium content in the liver is 341 micrograms / kg, and the selenium content in the kidney is 265 micrograms / kg, r...
