First, pick lean cows. Not all lean cows can be purchased for fattening. Only those lean cows, which are caused by poor husbandry and management, and heavy workload, can be quickly fattened after careful feeding and management. Picking lean cows must be careful, and avoid buying lean cows that are too old, extremely debilitated, suffering from chronic digestive diseases, or infectious diseases.
Second, disease prevention and deworming. A comprehensive inspection of the newly purchased lean cows and the introduction of foot-and-mouth disease, brucellosis and Clostridium perfringens vaccination can be carried out before polyculture. Before officially formulating fattening cattle, it is necessary to get rid of the stomach and intestines. You can take 4 capsules per 100 kg of body weight. In addition, the newly purchased cattle are susceptible to stress due to environmental changes, transportation, and scaring. , You can add 0.5% salt and 1% brown sugar in drinking water, let cows drink for 1 week. At the beginning of fattening, high-quality green and hay were fed first, and after a few days, a small amount of bran was fed and gradually transferred to fertilization.
Third, sub-fattening. The time for fattening lean cows should generally be controlled within 50-60 days and can be divided into 3 stages.
The first stage (6-8 days): The main thing is to tune the cattle to learn to eat mixed feed. The method is: let the cows hungry for 1-2 days continuously, and then mix a small amount of compound feed into the ammoniated straw. Usually, after 2-3 days of adjustment, the cow can feed on the trough.
The second stage (10-12 days): mainly restores the body condition of cattle. When feeding, it is necessary to gradually increase the feeding amount of compound feed. Each cow can feed 700-750 grams of compound feed and 100-120 grams of urea per day to the head (the use of ammoniated straw feed does not require additional urea). Hey, forage allows him to eat freely.
The third stage (35-40 days) is a critical period for rapid fattening. The daily compound feeding amount of each cow should be increased from 750 g to 1000 g, urea should be increased from 100-120 g to 150 g, and the fodder should allow cattle to feed freely. If conditions allow, you can also add appropriate amount of nightgrass at around 11pm every night to further improve the fattening effect.
Fourth, careful management. During the fattening period, try to create a warm, quiet and comfortable living environment for the cow. It is best to use a short rope for a fixed cow to reduce the amount of calf exercise and reduce its energy consumption. Daily brushing of the body once a day in the morning can promote blood circulation and metabolism of the body and enhance the appetite of the cow. During the fattening process, it is necessary to observe the feeding, excretion, and mental status of the herd and find that the disease is promptly treated.
During the late stage of fattening, we must observe the growth of cattle, and periodically perform weighing and body measurements. When we find that the beak is exposed, there is a back groove, rounding of the hips, fat deposition in both the bull scrotum and the cow's breast, and when the market is optimistic, It should be quickly slaughtered in order to achieve better economic benefits.
