Description

[0001] Methodology Area

[0002] The invention relates to the field of cattle breeding, and in particular to a method for fattening cattle.

[0003] Background Methods

[0004] Feeder cattle are in the early stage of growth for fattening cattle. The breeds include Charolais, Simmental, Angus, Limousin, Hereford, and yellow cattle. They have good beef quality, fast growth, and high feed conversion rate. They are large in size, with flat and wide shoulders, broad and deep chest, straight and broad back, round and large abdomen, curved ribs, wide hips, big head, large nostrils, large and deep corners of the mouth, a wide and moist nose, a well-developed lower jaw, large and bright eyes, fine and shiny hair, soft, loose and elastic skin, and are easy to fatten.

[0005] In modern animal husbandry, the quality and nutritional balance of cattle feed and cattle breeding methods are crucial to the healthy growth and production performance of cattle. Traditional cattle feed has certain limitations in meeting the basic nutritional needs of cattle. During the growth process of cattle, they often face challenges such as intestinal health problems, poor absorption of nutrients, and weak immune function. The abuse of antibiotics and veterinary drugs during the fattening process will also affect the taste of cattle meat, making the meat easy to have an earthy smell, and will also lead to increased drug resistance in cattle and weakened disease prevention and treatment effectiveness. The use of antibiotics and drugs will also increase the cost of cattle breeding, affect the cattle market rate, and bring economic losses to the breeding industry.

[0006] As an inorganic material, nano zinc oxide has shown great potential in the field of sterilization and disinfection. Nano zinc oxide has long been used in the medical field. It has certain antibacterial activity and has inhibitory effects on a variety of bacteria and fungi. Nano zinc oxide can play a bactericidal role in many ways, such as releasing zinc ions to interfere with the metabolic process of bacteria and destroy the cell membrane structure of bacteria. Nano zinc oxide also has a larger specific surface area and higher activity, which can contact and play a role with bacteria more effectively. In practical applications, nano zinc oxide is widely used in many fields. In the field of medical and health care, it can be used to make antibacterial dressings, ointments, etc., to help wound healing and prevent infection. In daily life, it can be added to personal care products such as toothpaste and hand sanitizer to play a role in sterilization and cleaning. In terms of environmental disinfection, it also has certain application prospects. It can be used in air purification, water treatment and other fields to effectively remove harmful microorganisms. However, in terms of cattle breeding applications, it is necessary to continue to explore in depth to achieve safer, more efficient and environmentally friendly cattle breeding. Summary of the invention

[0007] In view of the above shortcomings, the present invention provides a feed for cattle containing nano zinc oxide. The nano zinc oxide and active negative ion hydrogen water are used to prevent and treat cattle diseases, replace the use of antibiotics, improve the immunity of cattle, and promote digestion and absorption of cattle gastrointestinal tract, thereby achieving the purpose of increasing weight and production. The specific method is as follows:

[0008] A fattening method for cattle, using nano zinc oxide for fattening cattle, the fattening method comprising: (1) feeding the cattle with roughage and concentrate; (2) using nano zinc oxide solution for spraying management; (3) using nano zinc oxide and hydrogen water for drinking water management;

[0009] The concentrate comprises the following raw materials by weight percentage: 45-55% fermented cassava, 25-35% corn, 1-3% peanut bran, 5-15% soybean meal, 3-8% palm meal, and 1-4% cattle premix;

[0010] The roughage includes silage and hay;

[0011] The silage comprises 10-20 parts by weight of corn stalks, 5-8 parts by weight of sugarcane tail leaves, and 1-3 parts by weight of fruit residues.

[0012] Preferably, the silage further comprises 2-5 parts of alfalfa and 5-8 parts of ryegrass by weight.

[0013] Preferably, the concentrate comprises the following raw materials by weight percentage: 55% fermented cassava material, 30% corn, 2% peanut bran, 10% soybean meal, 5% palm meal, and 3% cattle premix.

[0014] Preferably, the preparation method of the cassava fermented material is as follows: grind commercially available cassava dry slices to 6-10 mesh to obtain cassava dry slice starch, put 34-39% of cassava dry slice starch, 0.5% of microbial agent, 0.5% of 23-27ppm nano zinc oxide, and 60-65% of water into a sealed can by weight percentage, mix them thoroughly, and then perform anaerobic fermentation at 35-40°C for 3-5 days and then dry them at 50°C until the moisture content is 15%, thereby obtaining the cassava fermented material; the preparation method of the silage is as follows: uniformly mix corn stalks, sugarcane tail leaves, fruit residues, alfalfa, and ryegrass according to the weight ratio, spray the microbial agent on the silage, let it stand for 1 day, spray 23-27ppm nano zinc oxide solution for mildew prevention, compact and seal, and perform anaerobic fermentation for 30-40 days, thereby obtaining the cassava fermented material;

[0015] Preferably, in the silage preparation method, the spraying amount of the microbial agent is 1% of the mass of the silage, and the spraying amount of the 23-27 ppm nano zinc oxide solution is 0.1% of the mass of the silage.

[0016] Preferably, the spray management is to use 48-52 ppm nano zinc oxide solution to spray wash the cattle every 8-12 days.

[0017] Preferably, the drinking water management is to give the cattle active negative ion hydrogen water every day. The active negative ion hydrogen water is small molecular cluster water, rich in negative hydrogen ions, and has a pH value of 8.0-9.0; every 8-12 days, the cattle are given a mixed liquid of nano zinc oxide and active negative ion hydrogen water, and the concentration of nano zinc oxide in the mixed liquid is 48-52ppm.

[0018] The active negative ion hydrogen water of the present invention is produced by the applicant by purchasing production equipment. Negative ion hydrogen water is obtained by water electrolysis or micro-electrolysis of special silicon ores to generate microcurrent in water flow. Active negative ion hydrogen water has a long shelf life, fast movement speed, strong penetration, dissolution, and metabolism, and is easier to exchange water inside and outside cells. The negative hydrogen ions therein have high antioxidant capacity, can remove harmful free radicals in the body, remove harmful metabolites and various wastes, avoid the occurrence of diseases, and repair cells oxidized by free radicals, restore their vitality, and reduce the occurrence of diseases. The applicant of the present invention has found that the use of nano zinc oxide and active negative ion hydrogen water for feeding to cattle can synergistically enhance the effect, which is beneficial to harmful bacteria in the cattle, neutralize or decompose some heavy metals, pesticide residues and other harmful substances, prevent and treat cattle diseases, replace the use of antibiotics, reduce the number of diseases in cattle and naturally eat more, thereby achieving the purpose of increasing weight and production; in addition, active negative ion hydrogen water is small molecular cluster water, and small molecular cluster water has strong solubility. The minerals therein are more easily dissolved in body fluids or blood, and can be better absorbed and utilized by the body. Because its molecular chain is shorter, narrower and smaller, it is easier to penetrate cell membranes, and it is easier to carry oxygen and nutrients, providing nutrition and energy to cells, which is very beneficial to the health of cattle.

[0019] Preferably, the microbial agent comprises 200 million cfu / g Bacillus subtilis, 100 million cfu / g lactic acid bacteria, 300 million cfu / g Bifidobacterium, 200 million cfu / g yeast, and 200 million cfu / g Lactobacillus acidophilus in a mass ratio of 2-3:1-2:1-2:1-2:1.

[0020] Preferably, in step (1), in spring and summer, grape seed oil, perilla oil, and evening primrose seed oil are added to the concentrate in a mass ratio of 1-3:0.2-1:0.2-1, and in autumn and winter, kapok seed oil and sea buckthorn oil are added to the coarse and concentrate in a mass ratio of 1-1.5:1-3, and the amount of spring and summer oil and autumn and winter oil added is 0.05-0.1% of the total mass of coarse and concentrate. In spring and summer, the temperature rises, microorganisms and parasites occur frequently, and spring and summer oil can help the cattle improve their disease resistance and resist hot and humid weather. In autumn and winter, the temperature is relatively low, and autumn and winter oil can help the cattle keep warm and gain weight. At the same time, the addition of oil can make the feed soft and easy to digest, increase palatability, and increase the cattle's food intake.

[0021] Preferably, the feeding method of step (1) is: adding concentrated feed, coarse feed and oil feed into a TMR machine, stirring for 1 hour and then feeding the feed to the cattle. After purchase, the cassava chips are ground to 6-10 mesh to obtain cassava chips starch and then fermented. The cassava chips starch with too much fineness will become sticky when entering the cattle's stomach, causing bloating and indigestion. However, the coarse feed does not need to be ground. After the coarse feed and the concentrate are stirred in TMR for 1 hour, the concentrate can be well adhered to the surface of the coarse feed. Cows are herbivores with four stomachs. Feeding the cows with coarse feed adhered to the concentrate can not only keep the plant fiber in the coarse feed from being destroyed and maintain the digestive capacity of the cattle's stomach, but also increase the feeding habit. The concentrate attached to the coarse feed is conducive to the cattle to evenly absorb the nutrients of the concentrate, prevent excessive viscosity from causing bloating and indigestion, and comprehensively assist in increasing the cattle's food intake. The daily feeding amount of the concentrate is 1.0-2.0% of the cattle's body weight, the daily feeding amount of the hay is 2-4kg / head, and the daily feeding amount of the silage is 3-5kg / head.

[0022] The cattle premix comprises, by weight percentage, 25% vitamin A, 15% vitamin D3, 15% vitamin E, 5% copper sulfate, 5% ferrous sulfate, 5% zinc sulfate, 18% medical stone, 10% calcium hydrogen phosphate and 2% salt.

[0023] Compared with the existing method, the beneficial effects of the present invention are:

[0024] 1. The present invention provides a fattening method for feeder cattle, which feeds feeder cattle with coarse feed and fine feed, uses nano zinc oxide solution for spraying management, and hydrogen water for drinking management to breed feeder cattle, thereby promoting the growth and development of feeder cattle, preventing and treating diseases, protecting gastrointestinal health, improving the resistance of feeder cattle, and improving the marketability of feeder cattle. The use of antibiotics is replaced, and the fishy flavor of products caused by long-term feeding of antibiotics is avoided, thereby realizing antibiotic-free and veterinary drug-free breeding, and the average daily weight gain can reach 2-3kg, and the marketability cycle is shortened to 4-6 months, so that feeder cattle can be marketed early and the breeding cost is saved.

[0025] 2. By using 48-52ppm nano zinc oxide solution to spray the cattle every 8-12 days, it can not only play a flushing and cleaning role, but also prevent and treat cattle diseases, improve immunity, replace the use of antibiotics, and do not require veterinary drugs. Nano zinc oxide can also sterilize and disinfect inflamed areas and small wounds on the cattle, promote inflammation and wound healing, keep the cattle in a good health state, and promote the cattle's eating and digestion and absorption, thereby achieving the purpose of increasing weight and production.

[0026] 3. The present invention uses nano zinc oxide solution and active negative ion hydrogen water as drinking water management for cattle. The mixed solution of nano zinc oxide solution and active negative ion hydrogen water has the effects of anti-oxidation and regulating metabolism, can reduce cattle gastric stress, disinfect cattle in vivo, prevent and treat cattle diseases, and improve immunity; adding nano zinc oxide and microbial agents to cassava starch to make cassava fermented feed to feed cattle can help maintain the balance of flora in the cattle stomach, inhibit the production of miscellaneous bacteria, promote cattle gastrointestinal digestion and absorption, and enhance the utilization rate of nutrients; cassava fermented feed provides rich nutrition and beneficial flora to the cattle stomach, maintains the intestinal microecological balance, and compared with unfermented cassava starch, cassava fermented feed is more It is easily digested and absorbed by the steers, and spraying nano zinc oxide on the silage can also play a role in mildew prevention. In the spring and summer seasons, the invention adds spring and summer oils of grape seed oil, perilla oil and evening primrose seed oil in a mass ratio of 1-3:0.2-1:0.2-1 to the concentrate, and in the autumn and winter seasons, adds autumn and winter oils of kapok seed oil and sea buckthorn oil in a mass ratio of 1-1.5:1-3 to the concentrate. In the spring and summer seasons, the temperature rises, microorganisms and parasites occur frequently, and the spring and summer oils can help the steers improve their disease resistance and resist hot and humid weather. In the autumn and winter seasons, the temperature is relatively low, and the autumn and winter oils can help the steers keep out the cold and gain weight. At the same time, the addition of the oils can make the feed soft and easy to digest, increase the palatability, and increase the food intake of the steers. Oil is rich in unsaturated fatty acids, which can affect the deposition and composition of fat in beef. It helps to reduce the accumulation of saturated fatty acids, increase the content of unsaturated fatty acids, make the fat distribution of beef more even, make the meat more tender and juicy, and improve the edible quality and nutritional value of beef. Oil can also serve as a carrier to assist the absorption and transportation of fat-soluble vitamins, ensuring that the cattle can fully utilize the vitamins in the feed to maintain normal physiological functions and growth and development. Under the combined effect, the growth rate of the cattle is accelerated, the feed conversion rate is improved, the health is good, the meat is more delicious, and the effect of increasing production and weight is significant.

[0027] 4. The present invention limits the use concentration of nano zinc oxide. The optimal use concentration of nano zinc oxide for cassava fermentation material and silage is 23-27ppm, and the optimal use concentration for drinking water and external spraying is 48-52ppm. The higher the concentration, the higher the corresponding cost. Moreover, the higher the concentration does not necessarily mean the better disease resistance effect. On the contrary, too high a concentration of nano zinc oxide will cause excessive sterilization and inhibit the fermentation of cassava fermentation material and silage. Too concentrated nano zinc oxide will also inhibit the beneficial bacteria in the cattle's stomach after entering the cattle's stomach, thereby causing indigestion and diarrhea in cattle, and reducing the slaughter rate. Although too low a concentration of nano zinc oxide can reduce costs, it is not effective in preventing and controlling diseases and inhibiting miscellaneous bacteria, and the average daily weight gain of cattle decreases, which also leads to a decrease in the slaughter rate.

[0094] It can be seen from the above test results that the fattening method of feeder cattle provided by the present invention, by feeding feeder cattle with coarse feed and fine feed, using nano zinc oxide solution for spraying management, and hydrogen water drinking management to breed feeder cattle, promotes the growth and development of feeder cattle, prevents and treats diseases, protects gastrointestinal health, reduces the incidence of disease, improves the resistance of feeder cattle, increases the marketability of feeder cattle, replaces the use of antibiotics and medicines, avoids the fishy flavor of products caused by long-term feeding of antibiotics, realizes antibiotic-free and veterinary drug-free breeding, the average daily weight gain can reach 3kg, and the marketability cycle is shortened to 4-6 months, so that feeder cattle can be marketed early, saving breeding costs.According to Examples 1-3 and Comparative Example 1, it can be seen that the active anion hydrogen water in the feed of the present invention has the effects of anti-oxidation and regulating metabolism, can reduce gastrointestinal stress in cattle, prevent and treat cattle diseases, reduce the incidence of disease, and improve immunity; According to Examples 1-3 and Comparative Example 2, nano zinc oxide can help maintain the balance of flora in the cattle stomach, promote gastrointestinal digestion and absorption, enhance the utilization rate of nutrients, and synergize with active anion hydrogen water to strengthen the health of the four stomachs of cattle, which plays a key role in increasing the food intake of cattle and increasing the weight of cattle; It can be seen from Examples 1-3 and Comparative Example 3 that the oil-rich Contains unsaturated fatty acids, which can affect the deposition and composition of fat in beef, help reduce the accumulation of saturated fatty acids, increase the content of unsaturated fatty acids, make the fat distribution of beef more even, make the meat more tender and juicy, and improve the edible quality and nutritional value of beef. In spring and summer, the temperature rises, and microorganisms and parasites are frequent. Spring and summer oil can help cattle improve their disease resistance and resist hot and humid weather. In autumn and winter, the temperature is lower. Autumn and winter oil can help cattle keep warm and gain fat. At the same time, the addition of oil can make the feed soft and easy to digest, increase palatability, and increase cattle's food intake. Oil can also serve as a carrier to assist fat solubility. The absorption and transportation of vitamins ensures that the cattle can make full use of the vitamin additives in the feed to maintain normal physiological functions and growth and development. The oil also plays an auxiliary role in lubricating the feed, making it easier for the cattle to eat. According to Examples 1-3 and Comparative Examples 4-5, the cassava fermented feed fermented with microbial agents provides rich nutrition and beneficial bacteria, maintains the balance of intestinal microecology, and prevents and treats gastrointestinal diseases of cattle. At the same time, compared with the unfermented cassava dry flake starch, the cassava fermented feed is easier to be digested and absorbed by the cattle. The cassava fermented feed can also improve the palatability of the feed and attract the cattle to eat. Under the comprehensive effect, the cattle The growth rate is accelerated, the feed conversion rate is improved, the health condition is good, the meat is more delicious, and the effect of increasing production and weight is significant; according to Examples 1-3 and Comparative Example 6, by using nano zinc oxide solution to spray the cattle body every 8-12 days, it can not only play a flushing and cleaning role, but nano zinc oxide can also prevent and treat cattle diseases, improve immunity, replace the use of antibiotics, and no veterinary drugs are required. Nano zinc oxide can also sterilize and disinfect inflamed areas and small wounds on the cattle, promote inflammation and wound healing, keep the cattle in a good health state, and promote the cattle to eat and digest and absorb, thereby achieving the purpose of increasing weight and production.

[0095] The test results of nano zinc oxide with different concentrations are shown in Table 3 below.

[0098]

[0099] From the above experiments, it can be seen that, considering the weight gain, cost, market rate and morbidity of feeder cattle, the optimal concentration of nano zinc oxide added to cassava fermented feed and silage is 23-27ppm. The higher the concentration, the higher the corresponding cost. Moreover, the higher the concentration, the better the effect. On the contrary, too high a concentration of nano zinc oxide will over-sterilize and inhibit the fermentation of cassava fermented feed. After entering the cow's stomach, it will also inhibit the beneficial bacteria in the cow's stomach, thereby causing indigestion, diarrhea, and reduced resistance in feeder cattle, resulting in a lower market rate. Although too low a concentration of nano zinc oxide can reduce costs, the effect of disease prevention and control is poor, the morbidity rate increases, and the average daily weight gain of feeder cattle decreases, which also leads to a decrease in the market rate.
