Embodiment 1

[0020] A basic concentrated feed is a commercially available concentrated feed for beef cattle, which meets the following indicators: the weight percentage of crude protein is 9-11%, and the net energy for weight gain is >5.76 MJ / kg.

Embodiment 2

[0022] A concentrated feed for increasing snowflake beef content in beef cattle, containing 300-600 mg daidzein per kilogram of concentrated feed, and the rest being the basic concentrated feed in Example 1 and cornmeal as a niacin carrier and diluent.

Embodiment 3

[0024] The preparation method of the concentrated feed that is used to improve snowflake beef content in beef cattle described in embodiment 2, its steps are:

[0025] (1) Preparation of daidzein premix: use cornmeal as carrier and diluent, mix cornmeal and daidinin at a weight ratio of 19:1, stir well and make a 5% daidinin premix; selection of daidinin Food-grade daidin with a purity of more than 98%;

[0026] (2) Preparation of concentrated feed: Stir and mix the daidzein premix and the basic concentrated feed according to the weight ratio to prepare the beef cattle fattening concentrate feed with a weight content of 600 mg / kg daidzein of the present invention.

Abstract

The invention discloses a concentrate feed for increasing the content of snowflake beef in beef cattle, which contains 300-600 mg of daidzein per kilogram of concentrate feed. The invention also provides a method for preparing and using a concentrated feed for increasing the snowflake beef content in beef cattle. The invention has the functions of increasing the fat content and marbling score of beef muscle, increasing the redness and chroma of muscle, reducing the moisture content and the pH after 24 hours of deacidification, and reducing the backfat thickness of beef cattle, and has the effect on other slaughter performance indexes No significant effect. The invention is suitable for use in raising castrated beef cattle in the fattening period, and is used for high-grade beef production.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry additives, and in particular relates to a concentrated feed used for increasing the snowflake beef content in beef cattle. The invention also relates to the preparation and use method of the feed additive. 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. The content of beef intramuscular fat (IMF) 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. The so-called "snowflake beef" refers to the fat deposited between the muscle fibers, forming obvious red and white, like ...
