Beef cattle fast fattening high efficiency
With the rapid development of the cattle industry, short-term fattening cattle continue to increase. More and more people use short-term fattening cattle as a good project to make a fortune and have achieved considerable economic benefits. However, there are still some problems in the fattening process of beef cattle. To effectively improve the short-term fattening of beef cattle and obtain higher economic benefits, the following work should be done.
First, choose a good fattening fattening cattle to choose improved Simmental, Charolais, Limousin and other crossbreeding, health and disease-free, weighing more than 250 kilograms, aged 1 to 2 weeks of non-castrated hybrid bulls, Select a cow with bright eyes, moist nose, large mouth, strong appetite, large feed intake, strong limbs, bright hair, long body, and deep and wide chest.
Second, adjust the temperature of the cowhouse The temperature in the cowhouse should be maintained between 5 and 10°C. If the temperature is too high or too low, it will affect the weight gain of the cow and the cow will fall out. In winter, the cowshed should be insulated, covered with plastic sheeting, and blocked with straw or mud to block the air leakage on the walls. This not only ensures the temperature inside the house, but also facilitates lighting. At the same time, the heat emitted by the cattle itself will not be lost too much. Normal fattening weight gain; summer and autumn to prevent sun exposure, rain, the cowshed to keep clean, dry, ventilated, so that it is warm in winter and cool in summer.
Third, to master the feeding method before cattle fattening to drive off the body and external parasites, every 10 kilograms of body weight with subcutaneous injection of 0.2 grams of insect nemesis, or oral dose of 0.1 grams per kilogram of body weight; after 3 days of deworming, oral administration of rhubarb to each cow Fire Jianwei scattered 350 to 400 grams. To drink enough water, the feed must be coarse and then fine, and finally drink water. In order to reduce energy consumption, no grazing, no exercise, home feed feeding, regular quantitative feeding, regular drinking water. Drink warm water in winter, the water should be clean and fresh, every meal let the cows full, especially roughage, should be fine, the forage should be clean. Spring and autumn winter fattening was chosen because of the hot summer weather and more mosquitoes affecting the fattening effect of beef cattle.
Fourth, choose a good feed to match according to the weight of the cattle and the weight gain rate to determine the amount and mix of feed.
1. Pre-finishing: 6-8 kg of distiller's grains, 2 to 3 kg of cornmeal, 0.75 to 1.0 kg of soybean meal, 50 g of salt, 50 g of additives, and 5 kg of corn stover. When starting to feed the lees, add a small amount. After 10 days of acclimation, gradually increase the amount of feed.
2. Medium-term fattening: 10 to 15 kg of distiller's grains, 3 kg of cornmeal, 1 kg of soybean meal, 50 g of salt, 50 g of additives, and 4 to 5 kg of corn stalks.
3. Late fattening: 10 to 15 kg of distiller's grains, 2 kg of cornmeal, 0.5 to 1 kg of soybean meal (or 100 g of urea), 50 g of salt, 50 g of additives, and 3.5 to 5 kg of corn stover. Eat the rest of the forage grass can not be overripe or overnight; distiller's grains should be fresh and high quality, corrupt, moldy and frozen or with sand can not be fed to prevent poisoning; such as the use of urea in place of soybean meal, urea should be dissolved in a small amount Water, mixed in the feed concentrate, should not be dissolved in water, drinking directly, urea feeding amount of adult cattle feed per head per day is not more than 100 grams is appropriate to avoid poisoning.
Fifth, do a good job in epidemic prevention and carcass health cattle to do a good job immunization and prevention of injections before the fattening, bovine body brush 1 or 2 times a day to keep cattle body hygiene; feeding utensils to be cleaned and disinfected twice a day (morning 1 time, 1 time in the afternoon). Cow beds, aisles, and walls must be regularly sterilized with caustic soda or lime. Casual workers are not allowed to enter the cowshed.
Six, choose a good slaughter period after 3 to 4 months of short-term fattening, cattle have reached a fat body, generally slaughter rate of up to 58%, the net meat rate of 50%, the average daily gain of up to 1.25 kg or more. At this time the fattening cattle has grown to a certain weight, if the market price is good, it should be sold quickly, selling a good price, otherwise it will increase the cost of feeding, reduce the rate of weight gain, affect economic efficiency.
