Four-section linear fattening feed technology for producing snowflake beef

Abstract

The invention relates to a four-section linear fattening feed technology for producing snowflake beef. At present, Japanese Kobe wagy is mainly introduced in the domestic market to serve as a provenance, crossbred cattle of local beef cattle breed serves as a bovine origin for producing snowflake beef, the snowflake beef is produced with the Japanese wagy fattening feed mode as reference, the slaughtering moon age is 30 months or more, the slaughtering weight is about 650 kg, and feed cost is high. The four-section linear fattening feed technology includes the following steps that castrated Houstain calves which are 2-3 months old, weaned and castrated, grow and develop well and weigh 80 kg or more are selected, according to the weight increasing law, protein and fat deposition law and the influence law of dietary nutrient level to body tissue, the whole fattening process of the castrated Houstain calves are divided into four stages, and stage weight increase indexes are set. The four-section linear fattening feed technology is used for producing the snowflake beef.

Description

[0001] Technical field:

[0002] The invention relates to a four-stage linear fattening raising technique for producing snowflake beef by using Holstein steers.

[0003] Background technique:

[0004] Snowflake beef is fat deposited between the muscle fibers, the muscles are red and white, and the intramuscular fat is distributed in dots, which looks like white snowflakes, hence the name Snowflake beef. Snowflake beef is rich in high-concentration "conjugated linoleic acid" and beneficial ingredients needed by the human body such as calcium, iron, potassium, zinc, and multivitamins; it has the characteristics of high protein, high nutrition, and low cholesterol. Nutrients such as B vitamins and minerals are more easily absorbed by the body; the meat is delicate, smooth, tender and juicy.

[0005] At present, the domestic market mainly uses imported Japanese Kobe Wagyu cattle as the provenance, and hybrid cattle with local beef cattle breeds as the cattle source for producing S...

Embodiment 1

[0028] A four-stage straight-line fattening feeding technique for producing snowflake beef, the method comprising the steps of: selecting 2-month-old to 3-month-old Holstein calves that have been weaned and castrated, have good growth and development, and have a body weight greater than or equal to 80 kg; The law of growth, the law of protein and fat deposition, and the law of the influence of dietary nutrition level on body tissue, divide the whole fattening process of Holstein calves into four stages and formulate the index of stage weight gain;

[0029] The first stage: Holstein calves aged 3 months to 7 months, with a daily gain of 1.5kg, the diet formula contains 16% crude protein, 78% total digestible nutrients, 0.68% calcium, 0.3% phosphorus, and crude semen The ratio is 7:3, and the final weight reaches 300±10kg;

[0030] The second stage: 8-month-old to 15-month-old Holstein steers, with a daily gain of 1.4kg, the diet formula contains 14% crude protein, 85% total dig...

Embodiment 2

[0035] According to the four-stage straight-line fattening feeding technique for snowflake beef production described in Example 1, test 1: select 4 10-11-month-old Holstein steers (25-day ligation castration), with an average body weight of 426.75 kg, as the test group A, 5 improved Wagyu cattle aged 10 to 11 months, with an average body weight of 301.88kg, served as the control group B, fed the same formula diet, the weight gain results are shown in Table 3, and the slaughter performance is shown in Table 4;
