Clever tricks to raise the shelf cattle

The cold winter in the north has increased the amount of heat released by cattle, which is unfavorable to the growth of beef cattle. Because the nutrients obtained by cattle are used to keep out the cold, they cannot be used to grow long meat. This is an uneconomical way to raise cattle. Therefore, fattening beef cattle needs warm circles to prevent cold damage. The general requirement of 5-21 degrees is the most appropriate, and the low temperature can affect the weight gain. The light in the house should not be too strong. The beef cow needs a darker light environment during the fattening period. This will allow the cow to rest quietly and fully chews and accelerate the weight gain of the beef cattle. Niu Xi is dry and afraid of moisture. He should keep the barn clean, dry, and fresh air, so that the cow has a good fattening environment and the cow will grow fast. Otherwise, it will lead to environmental stress in beef cattle and cause a decrease in weight gain. Do not avoid the negative factors such as the cold, moist and strong sunshine of the shed.
Reducing the amount of beef cattle reared Beef cattle do not have sports grounds, require feeding troughs, and eat and sleep. Raising the density of house feeding can be closely arranged and fed with a yak yak, so as not to give too much room for exercise and try its best to reduce the amount of exercise of the cattle in order to reduce the consumption of beef cattle. And to reduce and avoid disturbed by stress such as alarm and noise, keep quiet, fully chewed cattle after satiety, digestion and absorption of nutrients, so that the cattle less sleep, promote fat deposition, increase the fat.
In order to better adapt the shelf cows to eat more, grow more meat, and obtain high benefits as soon as possible in order to make the shelf cows better in the short term, it is necessary to raise the shelf cattle in three steps.
The shelf-feeding period of the shelf cattle is also called the transitional period, and the shelf-feeding of the cattle in the ring requires a feed and feeding adaptation process for 2 weeks.
Shelves of cattle into the circle of worms, drug combination method can be used to begin with 1.5 grams of nicotinic acid, albendazole is calculated at a dose of 10-15 mg per kg body weight, fasting feed. If necessary, two weeks later, 5 grams of levamisole and 20 grams of bidentine should be fed on an empty stomach to eliminate the harm of parasites to cattle and the plunder of nutrients. The stomach of beef can be artificially salted, rhubarb, or Jianwei can be used.
Individual weighing and numbering records were performed prior to fattening to determine the individual cow’s weight gain. Start the fattening process, first feed the hay and straw roughage, free access to feed, add 0.5 kg of mixed concentrate to each cow, and gradually increase the concentrate to 2 kg. For example, if cattle are bought from outside China, each cow can be fed with 350 mg of antibiotics and sulfa drugs to eliminate the stress during transport, and supplement minerals such as salt, calcium, phosphorus, and sulfur, and vitamins A, D and E. .
The mid-shelf (15-60 days) of the shelf-feeding cattle is also called the pre-fattening period. After the shelf-cow has passed the adaptation period, it has adapted to the feed and the house-feeding, but the continuation feed is still limited. The dry matter intake gradually reached 8 kg, the crude protein level was 11%, and the crude roughage ratio was 6:4, resulting in an average daily gain of about 1.3 kg. Concentrate formulation, 70% corn, 20% soybean meal, 10% bran. This low, high feed method can increase the feed efficiency by more than 5%, with an average daily gain of 1-1.2 kg.
The rearing period (60-120 days) is also known as the fattening period, which is a prosperous period for the weight gain of fattening cattle on the shelf. The increase in weight during this period determines the effect of fattening in the whole growth period and must be scientifically reared.
During the fattening period, 2 kg of mixed material is added, and 50 g of urea is added, which can increase the weight by more than 1 kg. The cows eat more concentrated material and can grow more meat, so that the beef cattle can reach the maximum fine material intake in the later period, and the dry matter intake should be gradually increased to 10 kg. In order to adapt to the rumen and reduce defects, it is possible to add rumen-regulatory agents, which can not only adjust the function of the rumen, but also increase the weight gain rate by more than 12%. The crude-to-coarse ratio is 7:3, and the daily gain is about 1.5 kg. The formula for the blended concentrate was 85% corn flour, 10% soybean meal, 10.5% bran, and 50 grams of additives. The intake of beef cattle in the latter period is about 2.5-3% of the body weight. Generally, 10 days before the cycle, the daily feed intake of the concentrate should reach 4-5 kg ​​for accelerating the fattening. The roughage should be eaten freely to aid digestion. And increase the appetite of cattle. At the same time, special attention should be paid if the appetite of the cattle is found to be reduced and the fattening momentum will be weakened. When the weight is around 500 kg, it can be slaughtered. Don't wait for the cows to go out in circles when they are full. Otherwise, it will affect the effect of cattle gain, and even drop them.
Choosing the suitable roughage for fattening beef cattle is to calculate the economic account. The cost for feed is about 75% of the cost of raising cattle. The pure cow has little chance of earning money, and has not made much money with a high proportion of raw feed for cattle breeding. Because cattle have a strong ability to use roughage, even if they use a roughage diet to fatten beef cattle, they can achieve good results. This is mainly because high quality hay can replace fine material. According to experiments, the fattening effect of 60% wolfberry and 40% concentrate in the diet is better than the effect of containing 85% concentrate and 15% coarse material in the diet, which not only reduces the cost but also improves the economic benefits.
Therefore, it is necessary to raise cattle scientifically, make full use of roughage and high-energy concentrates, and use only a limited amount of protein feeds to obtain good fattening effects. However, fattening should pay attention to methods. Before fattening, use roughage as the main ingredient, use less concentrate, raise to 350 kg, and then increase the amount of concentrate feed at the late stage of fattening to reduce roughage. In this way, cows can avoid acidosis. It can prevent cow bloating and winter diarrhea.
