Problems solved by technology

Currently, the selenium-enriched beef produced in the market simply adds sodium selenite or yeast selenium to the feed to feed beef cattle. The disadvantage is that the absorption and utilization rate is low, and the selenium content in the meat is low, which cannot achieve the effect of dietary selenium supplementation.

Embodiment 1

[0015] Taking the cattle with a body weight of 400Kg as the feeding body, they are fed with selenium-enriched beef cattle feed. The mass ratio of the feed is 50 parts of corn, 10 parts of soybean meal, 10 parts of bran, 15 parts of cottonseed meal, 5 parts of rapeseed meal, 5 parts of selenium-enriched premixed feed, wherein the mass ratio of each component of the selenium-enriched premixed feed is 2 parts of organic selenium, 1.2 parts of compound multivitamins, 20 parts of calcium hydrogen phosphate, 22 parts of stone powder, 20 parts of sodium chloride, 5 parts of various trace elements, 8 parts of rice husk powder, and 24 parts of medical stone. Feed for 33 days under the condition that the house temperature is 20°C, the relative humidity is 65%, and the stocking density is 6 square meters per head; feed 3 times a day, and the feeding time and feeding amount are as follows: 1st ~11 days is the group pre-feeding period, with quantitative feed intake and 3.5kg of concentrate...

Embodiment 2

[0019] Taking the cattle with a body weight of 450Kg as the feeding body, they are fed with selenium-enriched beef cattle feed. The mass ratio of the feed is 48 parts of corn, 9 parts of soybean meal, 8 parts of bran, 12 parts of cottonseed meal, 4 parts of rapeseed meal, 3 parts of selenium-rich premixed feed, wherein the mass ratio of each component of the selenium-rich premixed feed is 1 part of organic selenium, 1 part of compound multivitamins, 20 parts of calcium hydrogen phosphate, 21 parts of stone powder, 19 parts of sodium chloride, 4 parts of various trace elements, 6 parts of rice husk powder, 23 parts of medical stone. Feed for 33 days under the condition that the room temperature in the house is 17°C, the relative humidity is 60%, and the stocking density is 7 square meters per head; feed 3 times a day, and the feeding time and feeding amount are as follows: 1st ~11 days is the group pre-feeding period, quantitative feed intake, each cow is fed with 3.5kg of feed...

Embodiment 3

[0023] Take the cattle with a body weight of 460Kg as the feeding body, and use the selenium-enriched beef cattle feed to raise. The mass ratio of the feed is 52 parts of corn, 12 parts of soybean meal, 12 parts of bran, 15 parts of cotton meal, 6 parts of rapeseed meal, 5 parts of selenium-enriched premixed feed, wherein the mass ratio of each component of the selenium-enriched premixed feed is 3 parts of organic selenium, 1.5 parts of compound multivitamins, 22 parts of calcium hydrogen phosphate, 23 parts of stone powder, 20 parts of sodium chloride, 6 parts of various trace elements, 8 parts of rice husk powder, and 25 parts of medical stone. Feed for 33 days under the condition that the room temperature in the house is 18°C, the relative humidity is 65%, and the stocking density is 8 square meters per head; feed 3 times a day, and the feeding time and feeding amount are as follows: 1st ~11 days is the group pre-feeding period, quantitative feed intake, each cow is fed wit...

Abstract

The invention provides a feed for selenium-enriched beef cattle and a feeding method. The condition that the feed is comprehensive and balanced in nutrients is guaranteed. The feed formula and the feeding method are scientific and reasonable, the feed is rich and stable in selenium content, standardized breeding of the cattle can be effectively realized, and the rate of the cattle delivered to theslaughterhouse is increased, and the absorption of the selenium is easy. Besides, selenium elements in beef exist in the form of selenoprotein, so that the selenium elements are easy to absorb and utilize by human bodies, and requirements of human bodies for the selenium elements can be met. The invention further aims to provide the feeding method of the selenium-enriched beef cattle. The standardized breeding is performed on the beef cattle by the method, so that the selenium content in the beef can meet the requirements of a selenium-enriched standard. Experiment proves that for the cattlefed with the feeding method of the feed for the selenium-enriched beef cattle, the selenium content in the beef obtained after the beef cattle is slaughtered is stabilized to be 0.28-0.43mg / kg.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed for selenium-enriched beef cattle and a feeding method. Background technique [0002] Selenium is an essential trace element for humans and animals, and plays an important role in human life activities. Components, the diseases that may be caused by human selenium deficiency include energy deficiency malnutrition, hemolytic anemia, Keshan disease, Kaschin-Beck disease, hypertension, ischemic heart disease, liver cirrhosis, pancreatitis, fibroma, cancer, muscle cancer, infertility, diabetes, cataract, etc. People have mild or moderate selenium deficiency, and its signs or symptoms are not obvious, so it has not been taken seriously by everyone, but the World Health Organization has realized the harm of selenium deficiency, so various selenium supplement health products are produced in large quantities, which are common in the prior art The best way to supplement selenium is ...
