1. Preservation of cattle on the shelf 1 Precise selection of varieties: First, purchase the offspring of hybrids such as Charolais, Simmental, Limousin, and Forford, etc.; Steer cattle hybrid with local cattle. This kind of beef is of good quality, fast growth, and high feed rewards.
2 good appearance cattle: fattening shelf cattle to large size, shoulder width, chest width deep, straight back and wide waist, abdomen round, ribs bent, large hips, head, nostrils, deep mouth, The nose is wide and moist, the jaw is well developed, the eyes are big and bright, the hair is thin and bright, the skin is soft and loose and elastic. Use your thumb and forefinger to pinch a rubber band like a rubber band. Put the skin, such as cattle long meat and easy fattening.
3 Accurately determine the age of the cow: Choose the shelf age of the cow is best between 1.2-2.0 years old, easy fattening, good meat quality, grow faster, province feed.
4 Buy the bull that has not castrated: The bull's growth rate and feed utilization rate are higher than those of calves. Practice has proved that the daily gain of bulls that are not castrated is 13.5% higher than that of calves, and the meat quality is better than that of calves. Therefore, the bulls that are not castrated should be selected as far as possible when purchasing shelf cattle to improve the fattening effect.
5 Estimation of body weight: Generally, cows with a body weight of 300-400 kg should be fattened for more than three months, and the body weight can reach 500 kg or more, which is in line with the export standards.
6 Choose a cow with good sensation: If you have a good sensation, you can get a good quality carcass; poor sensation, less fat deposition during the fattening process, will reduce carcass quality. Very lean cattle are often poorly fed due to poor feeding and digestion, or due to certain diseases. Such cattle are not easy to fatten. In addition, overcrowding, excessively high or low temperatures, and heavy rainstorms all cause weight loss.
7 to buy healthy disease-free cattle: quarantine before buying cattle, on the shelves of infectious diseases and parasitic diseases cattle can not be purchased. After repurchasing, the animals should first be observed in isolation and dewormed in time. After 2 weeks of observation, they can be placed in the fattening group without any disease. The excrement should be detoxified.
2. Feeding and management of fattening The cattle are mainly house-fed and single-strained quail-feeding systems are used to limit movement. It is advisable to have a 0.4-0.5m length of the reins, so that the cows will not sleep. When feeding regularly, quantitative, individual feeding, feeding three times a day, the material should be coarse after the first fine, less feeding Tim Tim. Increase or change the feed gradually. Drink water once after each feeding, and increase the number of drinking water in the hot season. To maintain hygiene, regular disinfection. To achieve five net, that is, net forage, drinking water, cattle net, cattle net, cattle net. The barn should be kept dry and sterilized once a month. In the summer, the drug should be used to eliminate mosquitoes and flies.
The breeder should carefully observe the cow's intake, drinking water, rumination, feces, mental status, etc., and find abnormal treatment measures in time.
3. Fast fattening and diet preparation The shelf beef fattening is divided into three phases, about 100 days.
The first phase is the transitional period (15 days): First, the newly entered cattle are allowed to freely eat roughage, such as straw, hay, etc., do not get too short, about 5cm, after the tank is still mainly coarse, then Crude material can be cut into lcm or so, each day lkg fine material, and mix with the coarse material feed, the amount of fine material gradually increased to 2kg, as soon as possible to complete the transition period; the ratio of refined coarse material is 30:70, diet Protein level 12%, the daily gain can reach 800-1000g; the second is to repel insects, with Bu Ke Xing capsules per oral dose of 4 per 100kg body weight, or per 100kg body weight subcutaneous injection of insect Buster injection 2ml, can be repelled The vast majority of parasites in cattle and in vivo; the third is selenium supplementation, if the beef cattle appear in the fattening process but selenium symptoms, selenium must be added. General use of sodium selenite injection, the first subcutaneous injection or intramuscular injection of 20 ml, divided into several parts injection, every 2 months and then injected once, the same dose as the first time; the fourth is the stomach, buy After deworming on the shelf, each day 200g of artificial salt and 200 raw mothers, twice orally, once every 3 days, can achieve a good stomach effect; the fifth is vaccination, 1 week for fattening cattle After the vaccine injection.
The second stage from 16-60 days, dry matter intake to reach 8kg, dietary crude protein level of 11%, crude material ratio of 6:4, daily gain can reach about 1.7kg. Concentrate formula: 70% cornmeal, 20% soybean cake, 10% bran. Each cow is fed with salt 20g and additive 50g.
The third stage from 61-100 days, dry matter intake reached 10kg, dietary crude protein level 10%, refined coarse material ratio of 7:3, daily weight 1.9kg. Concentrate formula: cornmeal 85%, bean cake 10%, wheat bran 5%. Each cow is fed with salt 30g and additive 50g.
