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. Insecticide Many cattle farmers often use avermectin, ivermectin and other drugs to deter beef cattle. However, because the content of the deworming drugs is not up to the required standards, the deworming effect is not satisfactory. 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 early coarse material was 55%-65%, the concentrate was 45%-35%; the medium coarse material was 45% fine material was 55%; the late coarse material was 15%-25%, the fine material was 85%-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 most suitable temperature for ambient temperature is 10°C-21°C. Below 7°C, the calorific value of the 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, fattening method 1, the use of beef cattle weighting agents commonly used beef cattle weighting agents are: (1) zearalanol (also known as large reservoir). Post-early implants are performed 90 days before cattle slaughter. Under the same feeding conditions, the daily gain of cattle can be increased by 15.5%-20%, and the feed conversion rate can be increased by 6%-12%; (2) FP218 weight gain agent. 60-90 days before cattle slaughter, it can increase daily weight gain by 10%-15%, minority cattle by 20%, improve feed utilization rate by 10%-15%; (3) add 200mg daily to diets Rumen feeding increased daily gain by 16.3%; (4) Feeding 0.8%-1% of compound buffer in the diet, increasing daily gain by 11%-15%, and reducing feed consumption by 11%-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 in the diet by adding 1% -2% sodium bicarbonate or 0.3% -0.6% of magnesium oxide and bentonite 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 skills 1. Selection of fattening cattle Using good breeder bulls to cross with local yellow cattle, and using hybrid offspring as fattening cattle, the growth rate, feed utilization rate and beef quality are all higher than those of local cattle. In addition, obsolete bulls, infertile cows, low-yielding cows, and decommissioned cattle can all be fattened. All fattening cattle were required to be healthy and disease-free, and were treated with levamisole, and 15 mg per kilogram of body weight were fed for deworming, and the cattle were castrated 10 to 15 days before fattening to increase the fattening effect. 2. The feeding period for the adaptation period is generally 10 days to 15 days. Because the fattening cattle to the house do not adapt to the new environment, they must allow them 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 -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 -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 cattle indigestion can be fed dry yeast, daily -20 tablets -50 tablets, feces dry feed multi-dimensional 20 grams -30 grams and a small amount of vegetable oil. 3, Fertility feeding is generally 60 days -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 consume 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 cattle body twice a day -3 times to keep the cattle body clean and keep the enclosure warm in winter and cool in summer and air circulation. 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 and feed it at 6-8 am and 4-6 pm. It is better to feed the concentrate feed by mixing in wet roughage.
