1. Select fattening cattle to use hybrid bulls to cross cattle with local cattle, and use hybrid offspring as fattening cattle. The growth rate, feed utilization rate and beef quality are higher than that of local cattle. In addition, obsolete bulls, infertile cows, low-yielding cows, and decommissioned cattle can all be fattened. All fattening cattle were healthy and disease-free, and they were treated with levamisole with 15 mg per kilogram of body weight and fed with insecticide. The cattle were castrated 10 to 15 days before fattening to increase the fattening effect.
2, the feeding period of adaptation is generally 10 to 15 days. The fattening cows who feed are not suitable for the new environment. They must allow them to exercise freely, drink enough water, and feed a small amount of high quality grass or hay and bran to train their eating habits. 10 to 15 kg of concentrates are fed daily, including 80% of distiller's grains, 12% of corn semolina, 8% of wheat bran, 40 kg of green and hay, and 40 to 50 g of salt. The feeding method is to feed the hay first, then feed the concentrate, eat while mixing, and then eat until it is full. Such as bovine indigestion can be fed to dry yeast, 20 to 50 tablets per head per day, feces dry feed multi-dimensional 20-30 grams of a small amount of vegetable oil.
3, feeding fattening period is generally 60 to 80 days. Mainly promote the fullness of bovine body fat and accumulate fat. The feed formulation was 83% for distiller's grains, 11% for corn meal, 6% for soybean cake, 90-170 grams for urea, and 50 grams for salt. Pre-fertilization Each batch of cows is fed with 20-35 kg of fine material per day and 10 kg of hay; Late feeding of 30-40 kg of solid material, 1.5-2 kg of hay, or 25-30 kg of distiller's grains, 1.5-2 kg of hay, and 1.5 kg of bran , 3.5 kg of corn meal, 1.5 kg of cake residue, 150 grams of urea, 50 grams of salt, for 1 day feeding. Feeding should be quantified regularly, 3 times a day, and 1 at night. The supply of sufficient water, the feeding sequence is: first grass after the material, the first expected after the water. In addition, urea should be dissolved in a small amount of water and then sprinkled in the fodder or fed into the concentrate feed, should not be placed in the water for cattle to drink, so as not to cause poisoning.
4. Adding a large amount of beef cattle weighting agents at home and abroad showed that adding or sublimating weight-bearing agents in the beef cattle diet can effectively stimulate the pituitary gland, promote the secretion of auxin, and accelerate the synthesis of bovine protein. 1 Daily dietary supplementation with 200 mg of ruminant increases the daily gain by 16.3%. 2 In the subcutaneous adipose capsule of the left ear of beef cattle, each time 36 mg of “Big-Zi-Zhuang†was buried, the daily weight gain increased by 31.5%, and the feed-to-meat ratio increased by 24%. 3 Use needles to plant cattle and sheep's meat enhancer on the subcutaneous cartilage of the ear from about 2.5 cm away from the ear, increase the daily weight gain by 15% to 20%, and increase the feed conversion rate by about 10%. 4 The next time 200 mg of progesterone and 20 mg of estradiol benzoic acid were implanted in beef cattle, the daily gain and feed reward were increased by 18% and 7% to 13%, respectively. The use of implanted meat enhancers must be buried once in 60 days before slaughter.
