In rural areas, there are not many cattle farmers, but if you want to make money by raising cattle, large-scale beef cattle breeding is very important. With the love of pollution-free food nowadays, cattle farmers are more likely to learn more about the pollution-free fattening technology of beef cattle. The following is a detailed compilation of the pollution-free fattening technology of beef cattle. Let's learn together.

First, the choice of fattening cattle

1, variety selection

At present, the best beef cattle breeds imported from abroad should be preferred: Charolais, Limousin, Angus, Hayford, Short Angle, etc., for the breeding of the offspring of the father and the local yellow cattle as the female parent. It is characterized by large size, early maturity, fast weight gain and good meat quality. Followed by black-and-white bulls, the elimination of cows and the hybridization of black-and-white cattle and local cattle improved offspring. It is characterized by large body size and fast weight gain, but the meat quality is poor. Once again, it is a good domestic variety, such as Luxi Yellow Cattle, Nanyang Cattle, Qinchuan Cattle, Yanbian Cattle and Prairie Red Bull. Its characteristics are larger size, good meat quality, but slower weight gain and longer fattening period. Finally, it is an excellent individual of non-excellent varieties. Although these cows have poor body shape and poor performance, they are inexpensive and can also be used as a source of fattening cattle.

2, body appearance selection

Requires a healthy body, compact and well-proportioned, with longer limbs and body, high forequarters, and high hind limbs. The skin is soft and soft, the fur is soft and compact, the body is well developed, not picky eaters, easy to lick, easy to raise, and the whole body is "long rectangle".

3. Gender selection

According to the data, the growth rate and feed utilization rate of the bulls that are not castrated are not only significantly higher than that of the yak, but also more lean meat and less fat.

4, choose the age of cattle fattening

The age of fattening cattle has a great influence on weight gain and meat quality. The general rule is: the growth rate of beef cattle at the age of 1 is the fastest. As we age, growth rates and weight gains slow. The fattening cattle within 2 years can be produced and produced with high quality beef after scientific breeding. Cattle over 30 months old cannot produce high-quality beef.

5. Choose healthy beef fattening

Fattening cattle must come from non-epidemic areas without any infectious diseases or common diseases. At the time of introduction, there must be a quarantine certificate from the local veterinary department.

Second, scientific cooperation with the diet

1. The corn, soybean meal, bran and other concentrates used in fattening must be tested and tested, no residue, no harmful substances, no pollution, no mildew.

2, roughage for fattening, it is best to choose fertile soil near the cowshed, convenient watering, the application of fermented organic fertilizer plots to grow silage corn and high quality pasture. A shelf of fattening cattle requires 2-3 acres of corn stalks or 1-1.5 acres of whole planted with ears of silage corn. Silage corn and pasture, no residual pesticides.

3. Scientific and rational matching of feed: The varieties of refined and roughage in the diet should be diversified, which not only improves the palatability, but also promotes the complementarity of nutrition and improves the nutritional value and utilization rate of the feed. Reference formula for fattening beef concentrate: corn flour 62%, bran 10%, soybean meal 15%, sorghum 10%, shell powder 2%, salt 1%, appropriate addition of vitamin AD. Adding sodium bicarbonate at 0.3%-0.5% of the dry matter intake of the diet can effectively prevent rumen acidosis. The veterinary drugs, concentrated concentrates, additives, beef cattle weight-increasing agents, etc. should be selected from nationally recognized products. It is strictly forbidden to use residual drugs to ensure that beef cattle are kept in a pollution-free standard.

Third, scientific breeding

1. The newly purchased cattle enter the barn after strict disinfection, add anti-stress drugs such as multivitamin in drinking water, reduce the stress reaction, and feed the palatable feed to adapt to the local breeding conditions as soon as possible. Environmental conditions, and observed 10-15 days to confirm that no disease can be incorporated into the herd. After the cow is restored to physical strength, it is necessary to deworm and stomach in time.

2, in addition to the small bulls from the beginning of the concentrate, adding 10%-20% of high-quality roughage for short-term fast fattening, early production of high-quality high-grade beef, other fattening cattle in the early stage with chopped crop straw, high-quality pasture, silage Raw materials such as corn and dregs are mainly used, and the proportion of refined roughage is gradually increased from 2:8 to 3:7, so as to reduce hidden diseases, save concentrate and reduce costs.

3. After adapting to local feeding conditions for 60-80 days, the concentrate should be gradually increased, and the concentrate should be crushed to promote digestion and absorption. The coarse material is preferably silage corn and high-quality pasture, and the feeding of silage corn should be gradually increased from small to large to prevent diseases such as diarrhea, swelling, acidosis and the like. Fine and roughage should be gradually increased from 6:4 to 7:3.

4. In order to make the fattening cattle eat more, speed up the growth, increase the daily gain, use the daily feeding material 3 times or more in the fattening period, and freely drink water for 24 hours.

5, in the late fattening period, increase the amount of concentrate feed, the proportion of crude material is controlled within 20%, but the minimum limit of crude material can not be less than 10%, in order to facilitate the digestion of cattle. In the high-nutrition state, the fattening cattle will play the advantage of compensatory growth and accelerate the growth of muscle and fat.
