Description

Technical Field

[0001] The invention relates to the technical field of agricultural breeding, and in particular to a method for rapid fattening of beef cattle in southern high-humidity and hot areas. Background Art

[0002] Beef cattle are cattle used for meat, which are cattle that are mainly used to produce beef. They 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 side dishes. Among the beef cattle for slaughter and consumption, there are many varieties in China, and the production efficiency is good, including Simmental cattle, Charolais cattle, Limousin cattle and other fine breeds. The slaughter rate of fine breeds of beef cattle after fattening is 60%-75%, and the highest can reach 68%-72%; while the slaughter rate of Chinese local fine yellow cattle after fattening is 55%-60%, and the highest can reach more than 60%. Beef cattle generally gain weight fastest before the age of 1, and then the growth rate gradually slows down, so the slaughter age of beef cattle is 1-1.5 years old, and no later than 2 years old. Generally, the growth rate of bulls is faster than that of cows, and the meat quality of cows is better than that of bulls. Hybridization between different purebred beef cattle can increase the meat production of beef cattle by 15%-20%. Domestically, hybridization of purebred beef cattle with local cattle can also increase the meat production performance of the hybrid first generation of beef cattle by 20%-30%.

[0003] Due to the hot weather in summer, especially in the hot and humid areas in the south, the weather is extremely hot in summer. In order to resist the heat, cattle are very likely to lose fat. Moreover, such a high temperature and high humidity environment can easily cause many adverse effects on beef cattle production, such as heat stress, reduced feed intake, slowed weight gain, etc. Therefore, it is difficult to fatten cattle in the hot and humid areas in the south from June to September, which is equivalent to one-third less time for fattening cattle in a year, and there is no way to achieve the effect of fattening cattle all year round. If cattle can be fattened all year round, it will greatly increase the income of farmers, thereby generating extremely high economic benefits.

[0004] Regarding the question of how to fatten cattle in the hot and humid areas in the south from June to September, a patent document (CN105393981A) was retrieved for a breeding method for rapid fattening of beef cattle in the hot and humid areas in the south. The breeding method includes four processes: early preparation for rapid fattening of beef cattle, adaptation period for rapid fattening of beef cattle, transition period for rapid fattening of beef cattle, and late period of rapid fattening of beef cattle. It also includes a cooling process for beef cattle, a process for preventing skin diseases of beef cattle, and a process for preventing gastroenteritis of beef cattle. The breeding method requires strict control of the daily diet structure at each stage, and the operation is very cumbersome, making it inconvenient to promote and apply. In addition, during the rapid fattening adaptation period, rapid fattening transition period and later period of beef cattle, the patented product with the authorized patent number ZL201310442447.X and the invention name "Method and product for producing complete mixed granular feed for beef cattle from sugarcane tails" is adopted; or the patented product with the authorized patent number ZL201310442446.5 and the invention name "Method and product for producing complete mixed granular feed for cattle and sheep from cassava stems and leaves" is adopted; the mixed granular feed with the authorized patent number ZL201310442447.X is composed of sugarcane tails, corn, soybean meal, wheat bran, sodium bicarbonate, complex vitamins and trace elements, and the mixed granular feed with the authorized patent number ZL201310442446.5 is composed of cassava stems and leaves, corn, soybean meal, Wheat bran, sodium bicarbonate, complex amino acids and trace elements; among them, cassava stems and leaves are 200 yuan per ton, sugarcane tails are 220 yuan per ton, wheat bran is 296 yuan per ton, corn prices are up to 3,000 yuan per ton, soybean meal prices are 5,000 yuan per ton, according to the price calculation, the price of mixed pellet feed ZL201310442447.X is 1,700 yuan per ton, and the price of mixed pellet feed ZL201310442446.5 is 2,500 yuan per ton. Feed costs are not low.

[0005] The present application adopts cassava flake powder with a price of 2,000 yuan per ton, beer dregs with a price of 400 yuan per ton, and fresh mulberry branches and leaves with a price of 500 yuan per ton as the main ingredients to produce cassava flake fermented feed. It is calculated that the price of cassava flake fermented feed does not exceed 1,100 yuan per ton. It can be seen that the present application uses cassava flake fermented feed instead of traditional beef cattle fattening feed, which not only achieves the effect of fattening beef cattle all year round in the high humidity and heat areas in the south, but also greatly reduces the cost of beef cattle breeding, and the breeding operation is simpler, thereby further reducing the breeding cost.

[0022] The invention discloses a method for fast fattening beef cattle in hot and humid areas in the south, and also includes the prevention and treatment of parasitic eye diseases of cattle. Eye worm disease or sucking nematode disease of cattle is a parasitic eye disease caused by sucking nematodes parasitizing the conjunctival sac, under the third eyelid and in the tear duct of cattle. It is often found in warm and humid seasons with fly activities. Cattle of all ages are susceptible to it. The disease usually starts in May and June and reaches a peak in August and September. The disease of cattle is generally treated by oral antibiotics, injection of antibiotics and eye drops of insecticidal solution. Parasitic eye diseases, whether antibiotics are taken orally or injected, are likely to leave antibiotic residues in the body of beef cattle, making it impossible to ensure the food safety of beef cattle. The operation of using insecticide solutions to kill insects in the eyes is troublesome, time-consuming and labor-intensive. Beef cattle will not cooperate, and breeders are easily injured by cattle horns. Sodium bicarbonate, taurine and inulin are added to the daily drinking water of beef cattle. Sodium bicarbonate and inulin can increase the amount of water consumed by beef cattle. The taurine consumed can significantly increase the taurine content in the glands of beef cattle, thereby reducing the incidence of parasitic eye diseases in cattle.

[0095] From the above experimental results, it can be seen that the method for rapid fattening of beef cattle in high humidity and hot areas in the south of the present invention adopts cassava dry flake powder with a price of 2,000 yuan per ton, beer dregs with a price of 400 yuan per ton, and fresh mulberry branches and leaves with a price of 500 yuan per ton as main ingredients to produce cassava dry flake fermented feed. Compared with traditional beef cattle fattening feeds that rely on corn, soybean meal, and wheat bran as main ingredients, the feed cost of the present application is lower; fresh mulberry branches and leaves are rich in protein, essential amino acids, essential fatty acids, minerals, vitamins, flavonoids, polysaccharides, alkaloids and other substances; beer dregs are mainly composed of malt husk, leaf buds, insoluble protein, hemicellulose, fat, ash and a small amount of undecomposed starch and unwashed soluble The extract is rich in crude protein and trace elements; the cassava flakes are rich in starch, protein, fat, crude fiber and vitamins (vitamin A, vitamin B1, vitamin B2) and other nutrients; the fermentation compound is a mixture of Bacillus subtilis, Lactobacillus acidophilus and yeast; the fermented cassava fermentation material has no aflatoxin and salmonella detected; the moisture content of the cassava fermentation material is 57.8-58.5%, the crude protein content is 5.2-5.5%, the crude fiber content is 3.2-3.5%, the crude fat content is 1.3-1.5%, the crude ash content is 2.0-2.3%, the lysine content is 0.18-0.22%, and the starch content is 22.5-23.5 g / 100g, and then add a composite powder composed of selenium mineral powder, zinc sulfate, molybdenum mineral powder, and zeolite powder to supplement calcium, selenium, zinc, molybdenum, silicon, aluminum, iron and other trace elements. The feed has high edible safety, good taste and strong palatability. The feed intake of beef cattle remains unchanged in the hot summer weather, and the beef cattle can be fattened at high temperature, so that the beef cattle in the high humidity and hot areas in the south can be fattened all year round; cassava fermented material is obtained by sealed fermentation of cassava dry flake powder, beer dregs, fresh mulberry branches and leaves, and fermentation composite bacteria agent, and then selenium mineral powder, zinc sulfate, molybdenum mineral powder, and zeolite powder are added. The composite powder can not only supplement various trace elements, but also inhibit the growth and reproduction of pathogens, maintain the microecological balance of the intestines and gastrointestinal tract of beef cattle, promote the absorption of nutrients, improve feed conversion rate, and reduce feed-to-meat ratio; the composite bacteria in cassava fermented feed can secrete and synthesize various natural antibiotics, enhance the body resistance of beef cattle, effectively promote the metabolism of beef cattle, supplement protease, amylase, phytase and other digestive enzymes to adapt to the nutritional needs of beef cattle for rapid growth and development; it can also synthesize amino acids, vitamins, and promote growth factors and other nutrients , promote growth, improve intestinal function of beef cattle, eliminate fecal odor, reduce the number of flies, improve the breeding environment, reduce stress response, produce high-quality beef cattle products, and ensure food safety; it also includes the prevention and treatment of parasitic eye diseases in cattle. Bovine eye worm disease or bovine sucking nematode disease is a parasitic eye disease caused by sucking nematodes parasitizing the conjunctival sac, under the third eyelid and in the tear duct of cattle. It is more common in warm, humid, and fly-active seasons. Cattle of all ages are susceptible to it. The disease usually begins in May and June and reaches a peak in August and September. It is generally treated with oral antibiotics and injections. There are three methods to treat parasitic eye diseases in cattle: injecting antibiotics and using insecticide solution to kill insects. Whether it is oral antibiotics or injection of antibiotics, antibiotics are easily left in the body of beef cattle, which cannot ensure the food safety of beef cattle. Using insecticide solution to kill insects is troublesome, time-consuming and labor-intensive. Beef cattle do not cooperate, and breeders are easily injured by cattle horns. Sodium bicarbonate, taurine and inulin are added to the daily drinking water of beef cattle. Sodium bicarbonate and inulin can increase the amount of water consumed by beef cattle. The taurine consumed can significantly increase the taurine content in the glands of beef cattle and reduce the incidence of parasitic eye diseases in cattle.

[0096] Although the present invention has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements may be made thereto based on the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection claimed by the present invention.
