Spring is the fastest growing season for beef cattle during the year. In order to ensure that the beef cattle have a faster growth rate, the methods, techniques and precautions for fattening beef cattle are introduced to the breeders. First, fattening points 1, deworming Many cattle farmers commonly used avermectin, ivermectin and other drugs on beef cattle anthelmintic, but due to buy deworming drug content does not meet the required standards, resulting in deworming effect is not ideal . The author recommended phenyzalazole to everyone and added 0.5 kg of phenabendazole per ton of feed. Feeding was carried out according to normal feeding methods. Both of them had good repellent effects on the parasites of beef cattle in vitro and in vivo. 2, stomach due to improper feeding methods or feed is not clean and other reasons, it is often easy to cause beef cattle rumen, valve stomach deposition debris, resulting in poor appetite, indigestion. At this time, it is advisable to feed 1% of soda water on an empty stomach, and after the meat steaks are out of debris (as a criterion for judging the black dilute feces), start feeding the fattening feed again. After the stomach, the cow has good spirits and strong appetite. 3, a reasonable preparation of feed young cattle in the growth and development stage, the main weight gain muscle, so need more protein feed (cake type); adult cattle and fattening late fat-based, so need to be higher Energy feed. (1) The proportion of refined and roughage. The coarse material in the previous period is 55% to 65%, and the fine material is 45% to 35%; the medium coarse material is 45% fine material is 55%; the late coarse material is 15% to 25%, and the fine material is 85% to 75%. (2) Nutritional level. In the early stage of fattening, the nutrition level should not be too high, and the type of nutrition should be middle and high. (3) Feed shape. In general, the effect of granular materials is better than that of powdery materials, which leads to a significant increase in daily weight gain. Fine material crushed should not be too fine, roughage to cut the short best use of the effect. 4. The age and age of fattening cattle have a great influence on the weight gain of cattle. The general rule is that beef cattle gain the fastest weight in the first year of birth. In the second year, the weight gain is only 70% of the first year. In the third year, the weight gain is only 50% of the second year. To obtain high-grade beef with high economic efficiency, it needs to be slaughtered at 18-24 months of age. 5. Sex and gender influence the fattening rate of cattle. Under the same feeding conditions, the bulls grow fastest, followed by calves, and the cows are the slowest. If bulls are fattened within 24 months of age, it is better not to castration. 6. The optimum temperature of ambient temperature is 10°C—21°C. Below 7°C, the calorific value of bovine body increases. The maintenance needs increase, and more feed is consumed. The ambient temperature is higher than 27°C and the feed intake of cattle is reduced. Increased weight gain. Second, the fattening method 1, the use of beef cattle weighting agents commonly used beef cattle weighting agents are: (1) corn jacosanol (also known as large storage Zhuang). After the cattle are slaughtered 90 days before ear implantation, under the same feeding conditions can increase the daily gain of cattle 15.5% to 20%, feed conversion rate can be increased by 6% to 12%; (2) FP218 weight gain agent. 60 to 90 days before cattle slaughter, one can increase daily weight gain by 10% to 15%, a few cattle up to 20%, improve feed utilization rate by 10% to 15%; (3) Add 200 milligrams to daily diet Rumen feed, the daily weight gain can be increased by 16.3%; (4) Feeding 0.8% to 1% of compound buffer in the diet, the daily weight gain is increased by 11% to 15%, and the feed consumption is reduced by 11% to 13%. (5) Feeding 0.5 grams of sodium bromide per 100 kg body weight of beef cattle increases daily gain by 17.5%. 2, to improve the modulation of roughage technology that is applied feed silage, straw ammoniation and micro-storage technology, improve the palatability of the straw and nutritional value, increase beef intake and digestibility. 3, the use of rumen buffer to add 1% to 2% of sodium bicarbonate or 0.3% to 0.6% of magnesium oxide and bentonite in the diet can prevent the ruminal PH value of beef cattle and liver abscess disease, and increase beef cattle Feed utilization of high concentrate feeds. 4. Appropriate addition of minerals, vitamins and trace elements In accordance with the feeding standards, beef cattle diets are supplemented with calcium, phosphorus and other minerals in addition to salt, and selenium-deficient areas should also be supplemented with 0.1 lppm selenium in beef cattle diets. . In addition, it is also essential to supplement adequate amounts of vitamin A, vitamin D, and vitamin E. Third, speeding techniques 1, selection of fattening cows using good breeder bulls and local yellow cattle hybrids, with hybrid offspring for fattening cattle, its growth rate, feed utilization and beef quality are higher than the local cattle. In addition, obsolete bulls, infertile cows, low-yielding cows, and decommissioned cattle can all be fattened. All fattened cattle were required to be healthy and disease-free, and were treated with levamisole and fed with 15 mg per kilogram of body weight. The cattle were castrated 10 to 15 days before fattening to improve the fattening effect. 2. The feeding period during the acclimation period is generally 10 days to 15 days. Due to the fattening cattle of the breeding house, they are not adapted to the new environment. They must be allowed to freely move, drink enough water, and feed a small amount of high-quality grass or hay and bran to train them. Eating habits. On the day of feeding green material 10 kg to 15 kg. Among them, 80% of distiller's grains, 12% of corn meal, and 8% of wheat bran. Feeding grass, hay more than 20 kilograms, salt 40 grams to 50 grams. 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 dry yeast, daily 20 to 50 tablets, feces dry multi-dimensional feed 20 grams to 30 grams and a small amount of vegetable oil. 3, feeding period is generally 60 days to 80 days. This period is mainly to promote the fullness of bovine body fat and accumulate fat. Feed reference formula: 2.65 kg of corn, 1.41 kg of bran, 0.8 kg of cotton kernel cake, 0.8 kg of bone meal, 25 g of salt, 20 kg to 30 kg of silage per cow per day, regular feeding, and daily feeding 3 Times, plus 1 feed at night. Provide enough water to supply warm water of about 20°C in the winter. Drinking water 3 times during the day and drinking 5 times during the day in summer. The feeding sequence was: grass first, first water. Early evening and moderate, with a variety of forage grass, ban on feeding mildew degenerate feed. To cut short hay, urea should be dissolved in a small amount of water and then sprinkled in the fodder or feed into the concentrate feed, should not be placed in the water for cattle to drink, so as not to cause poisoning. Cattle consumed 40 to 60 tablets of dried yeast per head. 4. Carefully manage the raising of fattening cows. One cow, one cow and one rope, to limit their movements and keep them in darker houses, reduce energy consumption, increase feed conversion rate, and use fertilizer to increase fat. Brush the body of the cow 2 or 3 times a day to keep the cow body clean and keep the enclosure warm in winter and cool in summer and the air circulates. Clean the bar, trough and site frequently to keep the house clean and dry. In particular, each batch of cattle must be thoroughly cleaned and disinfected once after slaughter. Feeding time should not be too long, it is recommended to feed twice a day, feeding in the morning 6 to 8 and 4 to 6 o'clock in the afternoon, the feeding method of the concentrate feed is preferably fed by mixing in the wet roughage.
