Embodiment 1

[0019] A basic concentrated feed for beef cattle on the market, meeting the following indicators: dry matter weight percentage> 83.46%, metabolizable energy> 14.90 MJ / kg, crude protein weight percentage> 13.5%, crude fat weight percentage> 4.27%, The weight percentage of calcium>0.32%, and the weight percentage of phosphorus>0.56%.

Embodiment 2

[0021] A concentrated feed for improving the fat content and meat quality of beef muscles, containing 500-1500mg niacin per kilogram of concentrated feed, and the rest are the basic concentrated feed in Example 1 and cornmeal as a niacin carrier and diluent.

Embodiment 3

[0023] The preparation method of the concentrated feed for improving the fat content and meat quality of beef muscles described in Example 2 includes the following steps:

[0024] (1) Niacin premix: use corn flour as a carrier and diluent, mix corn flour and niacin at a weight ratio of 19:1, mix well to make a niacin premix with a weight content of 5%; niacin Choose food grade with a purity of more than 99%;

[0025] (2) Preparation of concentrated feed: the niacin premix and the basic concentrated feed are stirred and mixed evenly according to the weight ratio to prepare a concentrated feed with a weight content of 1500 mg / kg niacin according to the present invention.

Abstract

The invention discloses a fine fodder capable of improving the content of intramuscular fat and the meat quality of beef. The fine fodder per kilogram contains 500mg-1500mg of nicotinic acid. The invention further provides a preparation method and a using method of the fine fodder capable of improving the content of intramuscular fat and the meat quality of beef. The fine fodder disclosed by the invention can significantly improve the marble score of longissimus dorsi muscle of beef cattle by 3.7, very significantly improve the content of intramuscular fat of beef cattle and also significantly improve the live weight before slaughter, net meat weight, meat-bone ratio, leg weight and eye muscle area of the beef cattle and the redness (a*) and brightness (L*) of beef without adverse effects on back fat thickness. The fine fodder disclosed by the invention is suitable for feeding of castrated beef cattle in the fattening period, is used for producing high-grade beef and has the characteristics that the feeding with the fine fodder is simple to operate, the fodder can be applied into production conveniently and can significantly improve economic and social benefits of beef cattle breeding industry, etc.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a concentrate feed for improving the fat content and meat quality of beef muscle. The invention also relates to a method for preparing and using the concentrated feed. Background technique [0002] With the improvement of people's income and living standard, the demand for beef is increasing day by day. However, with the increase in quantity, the overall quality of beef produced in my country is low, and the product structure is unreasonable, which cannot meet the needs of consumers. High-grade beef basically relies on imports. Intramuscular fat (IMF) content of beef is an important indicator to measure the quality of beef, especially the quality of high-grade beef. "Snowflake Beef" can be called a high-quality beef product. It refers to the fat deposited between the muscle fibers, forming obvious red and white, like marbled beef, so it is also called marbl...
