It is the key to improve the speed of weight gain and the quality of beef in the process of beef cattle breeding. In order to improve the economic benefits of beef cattle breeding, it is the key to take comprehensive and effective measures to improve the weight gain rate of beef cattle. It is necessary to strengthen the selection of varieties, select suitable varieties according to the field and local breeding conditions, and provide a comfortable breeding environment. In addition, strengthening daily management and providing scientific and reasonable forage feed is also the key to improve the weight gain rate of beef cattle. In addition, it is also necessary to use feed additives reasonably.

1. Variety factors

With the advancement of breeding technology and continuous optimization and improvement, there are many varieties of beef cattle, and the production performance of different varieties of beef cattle is different. The weight gain rate of beef cattle has a certain heritability. Therefore, it is necessary to do a good job in the selection of varieties when fattening beef cattle. The characteristics of beef cattle breeds in China are strong resistance, but the feed conversion rate is low and the growth rate is slow. Some foreign breeds have high feed conversion rate and fast weight gain. Therefore, local breeds in China can be selected for hybrid improvement with foreign breeds. The hybrid offspring obtained generally have the characteristics of fast growth and development, good meat quality and high feed conversion rate, for example, we can use Simmental, Charolais, Limusan and other beef cattle as the father and local yellow cattle as the female to obtain binary or ternary hybridization.

2. Environmental factors

A good breeding environment can improve the comfort of beef cattle, thereby increasing their feed intake and affecting the weight gain rate of beef cattle. If the breeding environment is not suitable, such as the temperature of the enclosure is too high, it will lead to heat stress in beef cattle, resulting in loss of appetite, decreased feed intake, slower weight gain, poor sanitary conditions in the enclosure, poor lighting, poor ventilation, etc., which will easily lead to the breeding and reproduction of a large number of pathogenic bacteria in the enclosure, making beef cattle sick, thus affecting the feeding and rest of beef cattle, resulting in slower weight gain. In addition, unreasonable light will also affect the absorption and deposition of calcium in beef cattle, thus affecting the development of their bones.

3. Management factors

The feeding management of beef cattle is an important factor affecting the weight gain of beef cattle, such as improper management of beef cattle, will seriously affect its growth and weight gain rate. Unreasonable grouping, feeding procedures confusion, not in accordance with the different stages of beef cattle feeding management needs are different this principle, the scientific feeding management of beef cattle, will lead to beef cattle growth and development is blocked, feed intake decreased, slow weight gain.

4. Dietary factors

Dietary factors are the most important factors affecting the rate of weight gain of beef cattle. Only when the excellent beef cattle breeds are fed to the appropriate diet can they give full play to the characteristics of the breeds and obtain the best daily gain. Beef cattle mainly feed roughage, therefore, feeding should pay attention to the quality and type of roughage. Some studies have shown that when beef cattle are fed with crop straw, the weight gain rate is average. If appropriate amount of concentrate is fed with concentrate, the weight gain rate can be significantly improved. Therefore, when beef cattle are fed with coarse feed, appropriate amount of concentrate should be fed with reasonable combination, but the concentrate and coarse combination should be reasonable, and the licking of licking bricks should be increased to supplement the trace elements required for individual differences.

1, select the appropriate hybrid varieties

In recent years, the widespread development of economic hybridization has made a significant contribution to improving the productivity of beef cattle. A number of experiments have proved that through hybridization between varieties, the growth rate of offspring can be accelerated, the feed conversion rate can be improved, the slaughter rate and meat yield of beef cattle are relatively high, and the meat yield can be increased by 10% ~ 15% compared with pure breed cattle. Therefore, in order to obtain a higher weight gain rate, it is very important to do a good job in the selection of beef cattle varieties, and which hybrid beef cattle is specifically selected for fattening, it needs to be determined according to local feeding conditions, market demand and feed resources.

2. Provide a suitable breeding environment

Beef cattle breeding needs to provide a suitable breeding environment. First of all, scientific site selection should be made. The site should be located in a place with high dry terrain, sunny leeward and good ventilation. There should be sufficient water source nearby and convenient transportation. The layout of the cattle farm should be reasonable, the distribution of each district should be reasonable, and the design of the cattle house should be reasonable, so that it is warm in winter and cool in summer. Control the environmental elements of the cattle house, including temperature, relative humidity, air quality, environmental sanitation, etc., do a good job in summer heatstroke prevention and cooling, strengthen ventilation, keep the air fresh in the cattle house, in addition, but also do a good job in the cattle house sanitation and regular disinfection work, in order to improve the comfort of beef cattle.

3. Strengthen management

To strengthen the management of beef cattle, beef cattle breeding should have a set of practical operating procedures and management system, beef cattle should be reasonably raised in groups according to age, sex, weight, etc., beef cattle in different fattening periods have different requirements for feeding management and nutrition, and beef cattle in fattening period can be divided into observation period, early fattening period, middle fattening period and late fattening period, in the early stage of fattening, beef cattle need to be immunized, dewormed and stomach, in order to formally enter the fattening period to prepare for the work, to the fattening period according to the growth and development of beef cattle feeding. In the fattening stage, it is necessary to feed regularly and quantitatively. If the feeding time and feeding method are changed arbitrarily, the weight gain of beef cattle will be affected. During the fattening of beef cattle, we should also pay attention to the appropriate amount of exercise, on the one hand, it can enhance the physique, on the other hand, it can let the beef cattle bask in the sun, which is beneficial to the growth and weight gain.

4. Reasonable feeding

Beef cattle fattening can not be separated from feed. Beef cattle mainly feed roughage. To feed beef cattle high-quality roughage, it is better not to use inferior crop straw as fattening feed. If it is used, it also needs reasonable processing, such as ammoniation, micro-storage or yellow storage, to improve the utilization rate of feed. The types of feed should be diversified as much as possible to increase the appetite of beef cattle and increase feed intake, need a reasonable combination of feeding the right amount of concentrate, but pay attention to the proportion, in the feed concentrate when the best feeding a certain amount.
