Spring is the season when everything grows. Farmers can do well in spring, which will have a multiplier effect. It will greatly benefit the improvement of aquaculture efficiency. Attention must be paid to the following matters. First, grazing must be controlled cattle in the spring grazing because of gluttony and easy to swell, before grazing should be fed to the amount of hay. At the same time, grazing cattle should be fed with a certain amount of nightgrass and mixed concentrate, and provide sufficient drinking water to allow the cattle to eat and drink enough. The order of feeding is to drink water first and then feed the appropriate amount of hay. When the cow eats 50% or 60% of the full weight, feed the mixed concentrate and at the same time, feed the cow with light salt water. Wait until the cow rests for 15-30 minutes before grazing. After the grazing came back, the cattle were provided with enough water and night grass to allow the cattle to freely drink and eat. Second, pay attention to the quality of fodder. The fodder that is fed to cattle in spring is usually stored in the previous year. Due to long storage time, there may be mildew in different degrees when feeding in spring. Poisoning often occurs after cattle eat. Therefore, the cattle feed in the spring must pay attention to the quality of the forage. For the forage, special attention should be paid to sun drying, mildew or water washing, and it is forbidden to feed the cattle with rotten moldy grass. When spring grazing (especially in the first 10 days of grazing) must prevent cattle greed and eat toxic foods, so as to avoid bloating or poisoning. The third is to pay attention to moisture-proof spring rain, wet environment, bacteria breeding faster, cattle susceptible to diseases. Therefore, it is necessary to diligently lay out the ground, diligently cover soil, diligently dry and diligently change the bedding, and occasionally sprinkle lime or ash in the cowshed to sterilize it by absorbing moisture. Cowshed ventilation is better, keep the air fresh. Fourth, forage grass should be diversified with short grasses and long grasses, high-quality grasses with sub-grasses, such as wheat grasses and straws with green hay, loquat leaves, peanut pods, and barnyardgrass, etc., so that evenly mixed forages have comprehensive nutrition, and cattle love to eat. . When feeding fine materials, it should be combined with soft and hard materials. For example, when feeding hard materials such as corn and soybeans, it can be mixed with bran, powder and other soft materials. Begin to feed the grass first, when the cow is half-full, add less concentrate, add more concentrate when it is full, and add scented material, such as stir-fry and stir in the grass, even if there is no grass The cow can also eat enough. The spring is short and long, and on the basis of feeding the cows during the day, it is necessary to feed a slot at night and feed 13-15 kilograms of grass every day. Fifth, supplementing energy feed and feeding urea is an important measure to supplement bovine body protein, which can be fed in appropriate amounts in winter and spring. Generally, calves older than 6 months are fed 40-60 grams, 70-100 grams of fattened cattle, and 150 grams of adult cows. Urea poor palatability, according to the 1% of the diet mixed with the fine material fed with grass, can not drink water within half an hour after feeding.
