Selection of fattening cattle, fattening beef cattle, selection of improved Simmental, Charolais, Limousin and other crossbreeds, healthy, disease-free, weight-bearing 250 kg or more, 1 week old to 2 weeks old, non-castrated hybrid bulls Choose a bright-eyed, moist nose, large mouth, strong appetite, large feed intake, strong limbs, light hair, long body, and deep and wide chest.
Adjusting the temperature of the cowhouse The temperature in the cowhouse should be maintained between 5°C 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 lose its weight. 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.
Grasp the feeding method before cattle fattening to drive off the internal and external parasites, subcutaneous injection of 0.2 ml per 10 kg body weight worms, or oral dose of 0.1 g per kilogram of body weight; after 3 days of deworming, each cow oral rhubarb to the fire health Stomach loose 350 grams 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.
Choosing a good mix of feeds depends on the weight of the cow and the rate of weight gain.
In the early stage of fattening, the distillers' grains are 6kg~8kg, cornmeal is 2kg~3kg, soybean meal is 0.75kg~1.0kg, salt is 50g, additive is 50g, and corn stalk is 5kg. When starting to feed the lees, add a small amount. After 10 days of acclimation, gradually increase the amount of feed.
The medium-term distillers' grain yield 10kg to 15kg, cornmeal 3kg, soybean meal 1kg, salt 50g, additives 50g, corn stalks 4kg to 5kg.
In the later stage of fattening, the lees are 10kg-15kg, cornmeal 2kg, soybean meal 0.5kg-1kg (or urea 100g), salt 50g, additive 50g, corn stalk 3.5kg-5kg. Eat the rest of the forage grass can not be overripe or overnight; Sprinkle spatter must 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 dissolved first in A small amount of water, mixed in the feed, 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.
Do a good job of prevention of epidemics and carcasses. Cows should be well immunized and prevent injection before fattening. Bovine body should be brushed once or twice a day to keep cattle body clean. Feeding utensils should be cleaned and disinfected twice a day (Morning 1 Times, 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.
After a short period of fattening from 3 months to 4 months after the slaughter period is selected, the cattle have reached a fattening body. Generally, the slaughter rate can reach 58%, the net meat rate can reach 50%, and the average daily weight gain can reach 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.
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.
