Fattening technology of shelf cattle what is shelf cattle?

With the continuous development of the aquaculture industry, many people have joined the big family of the aquaculture industry, and many people are very interested in the cultivation of shelf cattle, so the editor will briefly introduce the breeding technology of shelf cattle for everyone. First of all, shelf cattle fattening is an important link to increase the economic benefits of raising cattle. Therefore, the correct selection of shelf cattle is a key, mainly from the following aspects.

Fattening technique of shelf cattle

First, the choice of shelf cattle

1. Fattening cattle about 1.5 years old can produce high-grade and high-quality beef. However, the growth and development of Qinchuan cattle is slow, and under the traditional feeding method, the skeleton and body shape of Qinchuan cattle can not meet the fattening requirements until the age of 3 to 4 years old. Therefore, in order to obtain good effect and benefit of short-term fattening, healthy Qinchuan castrated cattle at the age of 3-4 years old should be selected. Because of poor fattening effect and low benefit, castrated cattle over 6 years old and eliminated basic cows are not suitable for fattening middle and high-end beef, but can only produce ordinary fattening cattle.

2. Physique: short head, wide forehead, big mouth, thick neck, wide, deep and long body drive, good forequarter opening, thin and soft skin, large physique, obvious edges and corners, wide and flat dorsal rump, fattening potential, body height 137cm, oblique length 150cm, body weight above 350kg. And the body is too short, narrow back bow waist, Takeshiri, thin body is not suitable.

3. the fattening time should be the best in spring and autumn. In the high temperature season from June to August, measures such as water curtain, roof rain and fan should be adopted to prevent heat and cool down and slow down heat stress, and heat preservation measures should be taken in winter, and the optimum environmental temperature for fattening beef cattle is 4 ℃ ~ 20 ℃.

2. Feeding technology

The use of high-energy diet, net energy can reach more than 30MJ/ days, the proportion of concentrate gradually increased to 70%, do not use green succulent and silage, energy feed should be based on barley, improve the proportion of high-grade beef cattle, ensure beef color and other quality and flavor.

1. Recovery period (10-15 days). Due to the stress response of factors such as transportation, environment and management, cattle are tired and lose 5% to 15% of their weight, and it takes a period of time to recover in order to adapt to the new environment, groups and feeding and management methods. The diet is based on high-quality green hay and wheat straw, with adequate drinking water, no concentrate on the first day, a small amount of wheat bran on the second day, and 3 days later to maintain the original farmer or farm feed. And complete quarantine, epidemic prevention, deworming and isolation observation.

2. The transition period (15-20 days). Gradually realize the transformation from the raw material type to the concentrate type. After the shelf cattle recover and adapt, reduce hay, increase wheat straw, feed 4~6kg/ head of roughage every day; keep 13%-15% crude protein in concentrate, and gradually increase the amount of feed to 4kg/ day to ensure that each head is net energy 37~52MJ/ day.

3. During the fattening period, stop feeding green hay, forbid to feed green succulent feed, mainly wheat straw and rice straw, feed 3-4 tons per head per day, and gradually increase concentrate, so as to increase concentrate 2kg/ head every week, crude protein to keep 8%-10%, and daily concentrate feed to stabilize at the head of 6~8kg/ until it is out of column.

III. Management

1. Adequate drinking water should be free drinking water or drinking water not less than 3 times a day, and drink warm water in winter.

2. During the recovery period, albendazole was taken orally at a dose of 10 μ g / kg body weight. 2%-4% permethrin can be used to kill external parasites. When the weather is clear, the shower can kill parasites such as ticks on the body surface, and can also avoid mosquitoes and flies. After 3 days of deworming, rhubarb soda tablets 50-80 tablets were used twice a day for 2 days, and then Chinese herbal medicine Jianwei Powder 500g/ was used for 2 days to strengthen the stomach and promote digestion.

3. Fenced according to different physical size and strength, the fattening period was 15 heads at most, and the group of 6-8 heads was the best, and it was relatively stable. During the fattening period, each small group could only come out, no longer entered the cattle, and the fence area was 12~18m2.

4. Feeding times: 2 or 3 times a day in the early stage of fattening, 6 hours between them, and free feeding in the later stage.

5. Keep the barn dry and hygienic. The barn must be cleaned before entering the cow, thoroughly sprayed with 2%-4% caustic soda, and then dried into the cow.

6. Observation and weighing during the fattening period, the ruminant, spirit and feces of each cow should be observed. Diseased cattle should be isolated in time and raised separately for treatment. If there is gas, feces are thin and smelly and there are undigested concentrate, concentrate should be reduced or stopped. During the fattening period, the weight was weighed every 30 days. The method was to weigh twice on an empty stomach in the morning, take the average value as one, calculate the daily increase, and adjust the diet formula according to the daily increase to make the daily gain maintain 0.8~1.2kg.

What is a shelf cow?

Shelf cattle is a breed of cattle. First of all, it is necessary to buy shelf cattle that are crossbred with local cattle, such as Charolais, Simmental, Limousin, Heyford, and other foreign improved breeds of beef cattle. Secondly, buy the cross offspring of Holstein bull or Holstein bull and local cattle. This kind of beef has good meat quality, fast growth and high feed reward. Shelf cattle are characterized by large size, flat shoulders, deep chest, straight waist, round abdomen, curved ribs, broad buttocks, large head, large nostrils, large corners of mouth, broad and moist nose, developed lower palate, large eyes, hairy and bright, soft and loose skin and elastic skin, squeezed with thumb and index finger like a rubber band, with fingers inserted into the back of a grip, a large handful of skin, such beef long meat, easy to fatten.

What is the best fattening effect of shelf cattle?

In terms of the growth and development of cattle, calves and adult cattle mainly rely on the growth of muscles, bones and various organs to increase body weight, while adult cattle mainly rely on body fat storage to increase body weight. The sexual maturity of cattle is 8 ~ 18 months old, and the body maturity is 3 ~ 5 years old. the sexual maturity of breeding breeds is earlier than that of the original breeds, the sexual maturity of cows is earlier than that of bulls, and that of nutritious cattle is earlier than that of malnourished cattle. To this end, the choice of shelf cattle must be under 5 years old, generally choose 1.5-2.5 years old shelf cattle fattening effect is the best. After 2-6 months of intensive fattening, the best economic benefit can be achieved.

What kind of frame cattle are suitable for fattening?

The physical condition is related to the length of the fattening period, the better the fatness is, the shorter the fattening period is. As for the short body, shallow chest narrow back-pointed rump, showing a serious hunger condition, growth and development hindered cattle, should not be used as shelf cattle.

This is the end of the introduction of shelf cattle and fattening techniques. I believe we already have a simple understanding of shelf cattle and breeding techniques. However, if you want to engage in the breeding industry, I believe it is not easy, but only through suffering can you become a superior person. I believe that if you stick to it, there will be a harvest.
