All old people who have no teeth, have severe digestive tract diseases or have other diseases have no fattening value and should be eliminated so as not to waste feed and labor. Due to poor feeding and management, poor feed quality, heavy workload, or lean cows that have physical disability but do not affect the fattening effect or suffer from parasitic diseases, these lean cows are less expensive in the market and are highly efficient. The first choice for fast fattening, once this type of lean cow has been carefully bred and managed, it will often get twice the result with half the effort.

Deworming stomach

The method is to administer 4 capsules per 100 kg body weight of oral bupropion capsules or 2 ml of subcutaneous injection of insect venom per 100 kg of body weight to eliminate most parasites in vivo and in vitro. In addition, the newly arrived cattle are vulnerable to stress due to environmental changes, transportation, and startle. They can add 0.5% salt and 1% brown sugar to drinking water, drink for 1 week, and feed more quality grass or greens. In the hay, a small amount of bran was fed after two days, and gradually it was transferred to feed fertilizer. During the fattening process, it is necessary to observe the feeding, excretion, and mental status of the herd, treat minor illnesses promptly, and severely slam the animals.

Segmental fattening

The old disabled cattle are fattening, mainly to restore the weight and volume of the muscle tissue of the lean cow, and to improve the flavor and tenderness of the beef by depositing fat. Therefore, the time for fattening a lean cow should generally be controlled at about 60 days, and it can be divided into three stages for fattening. The first stage is mainly to adjust the cattle to learn to eat mixed feed, about 6 to 8 days. The method is to use a small amount of ingredients (formula: corn (2399, -15.00, -0.62%) 57%, bran 10%, peanut cake 25%, fried soybeans (4780, 25.00, 0.53%) 5%, bone meal 1.5% , trace elements 0.5%, salt 1%; or corn 50%, soybean cake 22%, bran 25%, calcium hydrogen phosphate 1.5%, auxin 0.5%, salt 1%), mix in ammoniated straw feed, Or let the cows hungry for 1 to 2 consecutive days to make them hungry before feeding them. Generally, after 2 to 3 days of training, the cows can feed on the trough. The second stage is mainly to restore the body condition, about 10 to 12 days. Gradually increase the amount of ingredients used in feeding, each head of cattle can feed 700 ~ 750 grams per day, urea 100 ~ 120 grams, fed three times, forage to allow them to eat freely. If ammoniated straw feed is used, urea is no longer added. Stage 3 is a critical period for rapid fattening, which takes about 40 days. The amount of batch feed per cow per day should be increased from 750 g to 1000 g, urea should be increased from 100 to 120 g to 150 g, no additional urea should be used when using ammoniated feed, and sufficient quality hay or ammonia should be supplied. The straw feed allows the cattle to eat freely, so it is advisable to eat enough to eat. At night, they can also feed the right amount of nightgrass to further improve the fattening effect of the lean cows.

Careful management

The most suitable ambient temperature for cattle is 5-21 °C. During the fattening period, it is best to create a warm, quiet and comfortable living environment for the lean cows. It is best to use a short rope for the fixed cows in order to reduce the amount of exercise and reduce energy consumption. Brush the body once a day in the morning to promote blood circulation and enhance appetite. During the later stage of fattening, observe the growth status of the cows, measure them at regular intervals, or measure them with a body scale. When they are exposed, their fats have been exposed, there are backslots, hip circles, bull scrotum, and cow's breasts have deposited fat, and the market price When they are optimistic, they should be quickly listed for the best economic benefits.
