Principle of rapid fattening of frame cattle

Rapid fattening and ration preparation

Cattle fattening is divided into three stages, about 100 days.

The first stage is the transition period (15 days): first, let the cows who have just entered the pen freely eat roughage, such as straw and hay. And don't chop it too short, about 5cm. After putting it in the trough, it is still mainly coarse grains. At this time, the roughage can be chopped into lcm, and each lkg concentrate and roughage are mixed and fed every day, and the roughage amount is gradually increased to 2kg. The ratio of concentrate to roughage is 30: 70, the protein level of diet is 12%, and the daily gain can reach 800-1000 g; The second is insect repellent, that is, taking 4 capsules per head according to 100kg body weight or injecting 2 ml of insect repellent injection subcutaneously according to 100 kg body weight can repel most parasites inside and outside cattle; The third is selenium supplementation. If beef cattle have symptoms of selenium deficiency during fattening, it is necessary to supplement selenium. Generally, sodium selenite injection is used, the first subcutaneous injection or intramuscular injection of 20 ml is divided into several times, and the dosage is the same as 1 time every two months. Fourth, strengthen the stomach. After the purchased cattle are deworming, 200 grams of artificial salt is taken orally and 200 pieces of cow are fed to the mother twice a day for 3 days, which can achieve good stomach strengthening effect. The fifth is vaccination. Fattening cattle are vaccinated after 1 week.

In the second stage 16-60 days old, the dry matter intake should reach 8kg, the dietary crude protein level should be 1 1%, the concentrate/roughage ratio should be 6: 4, and the daily gain could reach about 1.7kg. The concentrate formula is: corn flour 70%, bean cake 20%. Each cow is fed 20 grams of salt and 50 grams of additives every day.

In the third stage, at the age of 6 1 ~ 100, the dry matter intake reached 10kg, the dietary crude protein level was 10%, the concentrate/roughage ratio was 7: 3, the daily gain was 1.9kg, and the concentrate formula was corn flour 85. Each cow is fed 30 grams of salt and 50 grams of additives every day.
