Second, the selection of good opportunities for calving and mating is best to produce calves in the winter and spring, and before the end of grazing all the end. Because of the health of the calves born during this period, the development of rumen digestion in the summer, the use of pastures, and the ability to maintain high weight gain, etc., so the puerperal period is arranged in January-April, and the most appropriate period of insemination should be It is 4-8 months.
Third, the milk fattening
1, early weaning: breast-feeding shortened to two months, breast-feeding was reduced to 250 kg.
2. Adopt special feeding and management: (1) eat enough colostrum; (2) feed in stages; (3) cultivate in a single cage; (4) ensure sufficient drinking water; (5) prevent nutritional dysentery diarrhea.
Fourth, the new method of alkalinization of Artemisia sphaerocephala and ammoniation of Artemisia sphaerocephala is changed from soaking to spraying. After treatment, the wormwood is no longer washed with water, and cattle are fed directly. When spray treatment, the alkaline water is generally used in an amount of 4-5% of the amount of the straw, and is formulated into a 30-50% solution.
5. The semi-dry storage and the sand silage silage will be silage when the raw materials are air-dried to moisture content of 40-60%, the quality will be greatly improved, and the weight gain will increase.
6. Use of non-proteinaceous nitrogenous substances as a protein source In addition to emphasizing the scientific use of urea, the current new products include methylol urea and nitrouremic urine, which can increase the weight gain by 21%.
VII. Molded feed Forming feed can increase feed remuneration, improve palatability, save feed, and facilitate transportation and storage. The most common are pelleted feeds, hay cakes and feed bricks (blocks).
8. Appropriate choice of weighting agent Ruminin can increase the daily gain of beef cattle, from the promotion of sexual maturation of cows, protection against acidosis, bloat and coccidiosis. The daily dosage is 150-200 milligrams per day. Currently, it is usually taken orally. There is no need to stop the medicine before slaughter. If combined with growth-promoting drugs, the effect is better. Other weighting agents such as heifers, norgestenone acetate used in adult cows, progesterone used in calves, and estradiol used in male volunteers should be selected according to different subjects.
