Several fattening techniques for cattle

First, the bad dregs are used as fertilizer in the bad residue feeds. Generally, in young boar fattening, the use of distiller's grains accounts for about 40% of the dry matter of the feed. In the case of fattening cattle, the use of distillers grains in the amount of 30% to 35% is effective, which can improve the carcass quality grade without any harm to the cow. . When feeding bad residue feeds, attention should be paid to the following matters: (1) The bad residue feed should be fed with straw feed and silage. When mixing with silage, sodium bicarbonate should be added to the diet. (b) Long-term use of distillers' grain, vitamin A should be added to the diet and 10,000 to 100,000 international units per head per day. (3) The bad residue feeds and other feeds should be fed well after they are fully mixed. (d) Mouldy feeds that are mildewed and degraded cannot be fed to cattle. (5) When feeding bad residue feed, urea or other protein feeds that account for 0.5% of the fresh weight of the feed can be added to improve the quality of the bad residue feed. (6) When mild diarrhea occurs in feedstuffs for the consumption of beef dregs, ruminal should be added to the diet; when the diarrhea is severe, the proportion of bad dregs in the diet should be reduced. Second, silage feed fat General silage feed can account for about 50% of the weight of feed dry matter. Adding 1% to 2% of sodium bicarbonate in the diet to reduce the acidity of the feed and increase the digestibility. The addition of 2% urea in the feed is more effective. Third, the application of weighting agents (a) antibiotics. Commonly used is rumen (ie monensin), the dosage is: grazing cattle 1 to 5 days per head per day 100 mg, 6 days after each head per day 200 mg, home feeding and finishing period, when the concentrate is the main food, each 150 to 200 milligrams per day for the head, and 200 milligrams per head per day for the coarse diet. The maximum amount is not more than 360 mg per head per day. (b) Chemical substances. Commonly used sodium bicarbonate can increase the growth rate of beef cattle and prevent acidosis. The general amount is 1% to 2% of the amount of mixed concentrate. (c) hormones. There are estradiol, testosterone, progesterone and so on. The method of use is mainly implanted. Under the skin close to the ear, 2 to 2.5 cm away from the ear cartilage ring is buried with a special implanted gun. The use of weighting agents should strictly abide by the requirement to stop planting 90 days before slaughter.
