1. Selection of fattening cattle. All healthy bred cows, adult cattle, and shelf cattle can be fattened. However, it is best to choose bulls with large skeletons and excellent breeds or crossbreeding cattle, and the best weight is 250-350 kg.

2. Grouping and deworming. Before the start of the fattening, proper grouping should be carried out according to the age, weight, and feeding ability of the cattle, so as to avoid unfavorable effects on the fattening effect and uniform deworming before fattening.

3. Grasp the fattening period temperature and humidity. The suitable temperature during cattle fattening is 5~20°C, the best is 6~8°C, the relative humidity is 20~40%, about 30% is the best. Therefore, the best season for cattle fattening is spring and autumn. The cowshed should be dry and moisture-proof, and fattening cattle should be produced in winter and summer. Attention should be paid to the cool winter and cool summer of the cowshed.

4. Short tethered. The purpose of short-term tethering is to minimize the movement of cattle, reduce their own energy consumption, in order to facilitate the saving of feed and promote weight gain. During the whole period of fattening, the cattle need to be lodged in the house. The method of tying the cattle is short bolting and bolting. The height of the cow should not exceed the highest level of the body at the time of standing, and lying down without affecting the activity of the head can reduce unnecessary activities of the cow without affecting the lying and rumination of the cow.

5. Feed formula feed. Feeding compound feed is the core of cattle short-term fattening technology. The feed should be scientifically processed, modulated and matched according to the digestive characteristics of the cattle. The 15 days prior to the fattening period is the period of adaptation, and the feed to the cattle gradually transitions to the standard for fattening diets. Tests and production practices have proved that the use of the following two feed formulas to feed fat cattle is better, with an average daily weight gain of 1.3-1.5 kg.

(1) Reference formula for conventional fattening diets: 7 kg of hay or straw, 7.5 kg of silage corn, 2 kg of corn flour, 2 kg of glutinous rice, 0.5 kg of soybean cake or soybean, and 100 g of salt, mixed with water and mixed into a moist state. In the feed combination, if there is no silage, the hay can be increased to 10 kg. If there is no ape, the corn flour can be increased to 3 kg. In terms of individual, depending on the situation, the daily amount of the investment should be adjusted according to actual conditions.

(2) Reference formula for bad grain fattening diet: 18~22 kg of distiller's grains, 1.5 to 2 kg of corn flour, 1.5 to 2 kg of hay, 0.5 kg of soybean meal, 100 g of salt, and evenly mixed. In feed formulation, hay can also be replaced with grass or silage, and grass or silage can be fed in 4 to 6 kg.

6. Feeding cows should be regularly quantified. The conventional fattening method is fed 3 times a day. The time is as early as 5:00, 12:00 and 19:00. The bad cattle fattening method is fed twice a day, the time is 7:00 am and 17:00 pm 00 hours. Each feeding time is 1.5 hours, and 30 minutes after feeding, adequate drinking water is provided, drinking water is preferably bean cake water or soybean water, and drinking water is taken care of in winter.

7 timely slaughter. When the fattening cattle are fed for about 3 months, the cattle are strong, the food is reduced, and the body weight is slowed down.
