Fine varieties are the key
At present, the better varieties of beef cattle in China are the first to promote Ximental, Charolais, Limousin, South Devin and other improved hybrids. The improved second-generation and third-generation beef cattle have many advantages, such as strong adaptability, resistance to roughage, easy fattening, rapid weight gain, and high slaughter rate. Therefore, choosing the fine breed is the key. Secondly, there is a direct relationship between the weight gain of beef cattle and its age. It is recommended to introduce improved beef cattle from 1 to 2 years old as the target for captive breeding.
Beef cattle "drinking" increase faster
Feeding a variety of beef cattle, in addition to providing adequate high-quality feed and mixed concentrate to ensure the nutrition needed for its growth and development, adding appropriate amount of wine in the feed can greatly accelerate the growth rate of beef cattle. The amount of alcohol added to the feed needs to be different for different types of alcohol. According to the author's feeding test, under normal circumstances, adding 10 grams of white wine or 50 grams of beer to the feed per head per day is the best, the growth rate is increased by more than 20%, and the quality of beef is better and the slaughter rate is higher. High, the proportion of net meat is greater.
Winter and spring "make up" fat
There is a large temperature difference between day and night in winter and spring. When the temperature is lower than 8°C, the beef cattle are not ideal. At this time, we should try our best to “make up†fat to make up for the lack of growth. Because fat is the best form of energy supplied by beef cattle and stored in the body, and it is a solvent for fat-soluble vitamins, it can quickly dissolve vitamins A, D, E, and carotenol to achieve optimal energy release. Therefore, on the basis of meeting the requirements of beef cattle for forages and concentrates, adding a small amount of fat, such as animal oils, vegetable oils, various oil residues, or high oil scraps, it will be found that the beef cattle in the winter and spring seasons are still better than others. .
Salt and salt bricks make you strong
Barium salt bricks are based on the growth and development needs of cattle, with salt as a carrier, adding calcium, phosphorus, iodine, copper, zinc, manganese, iron, selenium and other appropriate trace elements, made by scientific processing methods. The yttrium salt bricks are put into the trough for the free supply of beef cattle, which can effectively maintain the electrolyte balance of the beef cattle body, promote growth, increase feed conversion pay, reduce nutrient deficiency, and prevent rickets and nutritional anemia embolism.
Feeding young shoots against bloating
Cattle eat too much young seedlings easily bulging belly, which is acute gastric dilatation. Nowadays grass, young crops and other green grass can be described as numerous, do not look at cattle are very fond of adding it. If you accidentally allow the cow to eat more belly bulge, you can use 250 grams of cooked soybean oil to 500 grams of direct gavage, when you add some powerful rice vinegar, but for a long time, they saw the original bulging belly of cattle slowly subsided. If it is only a slight bulge, the odor sticks may be used to force their mouth to contain 10-20 minutes, and the symptoms of bulging belly will soon disappear.
