Breeding and Management of Beef Bull

Beef cattle, that is, beef cattle, is a kind of cattle mainly producing beef. Beef cattle are characterized by plump body, fast weight gain, high feed utilization rate, good meat production performance and good meat taste. Beef cattle not only provide people with meat products, but also provide people with other non-staple food. The prospect of beef cattle breeding is broad. Especially on November 30, 2011, the Ministry of Agriculture issued the National Beef cattle genetic improvement Plan (2011-2025), which provides a broader space for promoting the herd genetic improvement process and improving the production level and economic benefits of beef cattle.

Beef cattle have always been in short supply. globally, beef accounts for more than half of the meat in the developed regions of the world, while China accounts for only about 10%. The per capita share of beef is more than 50 kg in developed countries and 10 kg in the world, while it is less than 5 kg in China, especially in some parts of the south. China has entered into building a well-off society in an all-round way, and beef is an integral part of the well-off index. people pay more attention to the improvement of the quality and structure of good food, and the demand for beef, especially high-quality beef, will increase day by day.

The raising of beef bulls:

The nutritional needs of breeding bulls focus on protein, carrots and minerals, and energy is generally easy to meet and sometimes exceed in production, resulting in excessive fertilizer. Therefore, concentrate should focus on protein, accounting for 40%-50% of the total nutritional value, while energy feed should be dominated by barley and wheat bran, and less corn should be fed to avoid overweight bulls and affect seed performance. during the peak breeding season, eggs, milk, fish meal and other animal protein-rich feed should also be allocated as appropriate, and the coarse feed should be dominated by high-quality legume hay to control the supply of corn silage and rhizome succulent feed.

The standard of concentrate and roughage for adult bulls can be fed according to about 0.5 kg of concentrate and 1 kg of roughage per 100 kg body weight per day. The production practice can be handled according to the body condition, sexual activity ability, semen quality and breeding task of different bulls. In addition, adequate and clean drinking water is also essential for breeding bulls, but be careful not to drink water for half an hour before and after breeding.

Management of beef cattle and bulls

The main results are as follows: 1. The tethered bull wears a halter at 6 months after birth and pierces the nose ring at 8-10 months for control.

2. Weigh once every 2 to 3 months, check the change of body weight in order to adjust the feeding management, meat breeder bulls should prevent from being overfat.

3. Lack of exercise is a common problem in production. Exercise should be done at least twice a day for about 2 hours.

4. Brush and bathe regularly every day, especially pay attention to the key parts such as corners, forehead, neck, buttocks and tail root. Summer to take a bath, can play a role in relieving heat and cleaning.

5. To protect the hoof in spring and autumn, the keeper should always pay attention to the abnormal shape of the hoof.

6. The use of suitable semen collection times for breeding bulls is especially important for breeder bulls. Too many semen collection times lead to the decline of breeding bull's physique and poor semen quality, while too few semen collection times will affect the bull's sexual reflex and decrease the quantity and vitality of semen. Generally, semen can be collected 2 or 3 times a week, while semen can be collected once a week in hot summer and cold winter, the specific use depends on the actual situation.
