One of the key measures to increase the primary weight of the calf by the primary weight of the hybrid calf is the use of improved breeder bulls (eg, Ford, Simmental, Charolais, Libus, Shorthorn, etc.) ) For the male parent, hybrids were made using the larger native cow as the female parent. The hybrid calves produced by the crossbreeding have the advantages of strong adaptability, resistance to roughage, strong disease resistance, fast growth, high feed return rate, large individual cattle, short fattening cycle, full meat, high lean meat percentage, and fresh tender meat. High nutritional value, a variety of significant heterosis. Second, the feeding of pregnant cows to ensure that the primary calf body is large, strong physical fitness, it is necessary to grasp from the feeding period of pregnant cows. Grazing should choose pastures that are close to the barn and have excellent grass quality. It is best to go through artificial breeding grounds for replanting excellent legume feeds to allow cattle to eat well. If grassland is poor in grass quality and quantity, and the nutrition of pasture cannot keep up, it is necessary to adopt a combination of grazing and supplementation to supplement fine artificial pasture or high-quality hay. Each cow is supplemented with 0.5 kg to 0.6 kg of concentrate per day. It is forbidden to feed cows with contaminated fodder and unclean frozen effluent. Third, yak weaning body is important for the yak to obtain a higher weaning weight, and the yak should strengthen the feeding of the nursing cows before weaning and feed the young and tender forages, dry fresh grasses, and juicy legumes. And the amount of artificial feed with the proper amount to ensure that the cow milk is sufficient to meet the needs of calf suckling. At the same time, we must also do a good job of feeding calves. Yak feeding should be started from the first 15 days after the start of the lure, the light salt water or sugar water spray on the young and juicy pasture, let it gradually learn to eat grass under the leadership of the cow. Later, depending on the specific conditions of its growth and rapid weight gain, it is appropriate to feed supplemented concentrates that are easily digested. The amount of feed can be determined based on the amount of milk produced by the cow, the conditions of the grazing, the quality of the forage, and the nutritional status of the cow. Fourth, weaning calves for calves weaned generally after 70 days of age. Weaning yak should adopt separate methods of male and female breeding to prevent early mating and affect the calf's feeding and nutrient accumulation (preferably calf castration). Grasping yaks must provide a variety of adequate quality forage, so that nutrition is more complete and rich. Daily supplement with 0.5 kg to 0.75 kg of concentrate feed. When the quality of pasture is poor and the quantity is small, good quality legume legumes should be provided. In addition to grazing every day, winter and spring also need to raise the amount of feed supplemented with compound feed, each head supplemented with 0.75 kg to 1 kg per day. For beef cattle, beef cattle diets are used. Fifth, fattening hybrid yaks in the later stages of beef cattle are generally fattening around 15 months of age. In the last two months, it is necessary to grasp fattening and promote the fullness of bovine body fat. The fattening cattle diet can use distiller's grains, 25 kg to 30 kg, 5 kg to 7 kg of chopped hay, 1 kg to 1.5 kg of bran, 3 kg to 3.5 kg of corn meal, and 1.25 kg to 1.5 kg of detoxification rapeseed cake. Kg, urea 150g to 170g and salt 70g to 80g are mixed into compound feed. According to the principles of feeding fodder first, feeding compound feed, and finally drinking water; adopting a short rope to support during the feeding to reduce the exercise consumption; feeding time, quantitative, and qualitative; feeding 3 to 4 times a day, drinking water 2 times to 3 times; each time when feeding compound feed, it is necessary to mix the feed with water and mix it with dry and wet half distiller's grains, and then add bran, corn meal, detoxified cake and salt and mix well. At the end of the cow's life, mix a little corn meal to make the cow eat the food in the trough. Drink water 1 hour after each feed and feed 15 to 25 degrees Celsius clean hot water. In addition, care should be taken to keep the barn clean and dry, insisting on daily cleaning, so that the house is cool in winter and cool in summer, the air is circulated, the house is sterilized regularly, and food troughs are cleaned. Under good husbandry conditions, the hybrid beef cattle can weigh up to 400 kg to 600 kg after short-term fortification. At this time, they should be slaughtered and sold in time, and the next batch of beef cattle should be kept.
