Raising beef cattle fattening technology can not only increase beef production, but also significantly increase economic efficiency. After investigating some of the fattening households, the author found that in the fattening process of beef cattle, there is a situation that the supporting technology is low and the fattening effect is not obvious. Practice has shown that the implementation of supporting technology for fattening beef cattle can obtain significant fattening effect and economic benefits. Construction community First, choose the location of the beef cattle breeding community site selection, should follow the principle of the scale of fattening cattle farm selection site. If the conditions are not met, it should be adapted to local conditions and make full use of the local free space. However, it must be ensured that transportation is convenient to facilitate the entry and exit of feed and beef cattle. Second, the district beef cattle breeding area mainly consists of self-cultivation, shelf cattle fattening, self-cultivation and self-cultivation, and shelf cattle fattening combined with several forms. Self-cultivation and self-sustaining can make full use of roughage and reduce the cost of rearing, but it has a long service life and a slow turnover of funds. It is suitable for areas with poor economic conditions. The shelf cattle fattening investment is large, the demand for concentrate feed is large, the feeding cost is high, but the feeding cycle is short, the capital turnover is fast, and the economic benefit is high. The combination of self-cultivation and self-cultivation and shelf-fat fattening can make full use of the advantages of the above two, but the feeding and management are complicated. Third, layout design Beef cattle breeding community should include disinfection pools, cowsheds, cowsheds, isolation cowsheds, feed rooms, silos, ammoxidation pools, fecal sites, sewage treatment facilities, installed cattle and other facilities, but life The division of the district and the production area is not obvious. Each cowhouse kept cattle 3-5 heads, and the division of basic cowhouses, calving houses, yak breeding houses, bred cowhouses and fattening cowsheds was not obvious. Silo and ammoxidation pools are funded and built by the cattle raising households on a feeding scale. Generally, two pools are combined. This can save investment and improve equipment utilization. Silage tanks and ammoxidation tanks are generally located on both sides of the cowshed for easy retrieving. 4. Construction of Cattle Houses in Cattle Houses The construction of cattle houses is similar to that of large-scale cattle farms, but the requirements are low. Local materials can be fully utilized to reduce construction costs. In a warm climate, simple shelters can be established to save a lot of investment. In the hot summer and cold winter areas, a more stable open or semi-open cowshed can be built. Such a cowshed can be guaranteed in the summer. It is well-ventilated. In the winter, the cowshed is closed with plastic sheets and straw mats to facilitate insulation. Choose a good variety 1. Selection of good breeds or crossbred cattle It is recommended to introduce foreign fine varieties with high production rate, high feed conversion rate and good meat quality, such as Piedmont cattle, German cattle, Limousin, shorthorn cattle and Charolais cows. Introduce Angus cattle. These exotic species can be used for direct feeding, and their bulls can also be used for crossbreeding with local cows. Fine hybrids can be obtained and then fattened. In the short term, a large number of high quality beef cattle can be produced. Second, adhere to the self-breeding self-education from the analysis of the situation of some large cattle-raising households, a large number of cattle-raising households after the purchase of Qi Niu, the lack of feed and management funds, resulting in lack of stamina, extensive feeding, low efficiency. Through self-cultivation and self-education, it not only saves the cost of cattle purchase and transportation expenses, but also reduces the stress of cattle, avoids the battle between cattle and facilitates the management of fattening. 3. The age-selection test showed that the 1-year old cattle had the fastest growth rate. The 2-year-old cattle had a growth rate of 75% of the 1-year-old cattle, and the 3-year old cattle had a growth rate of 50% of the 2-year-old cattle. In order to achieve the slaughter weight requirement, 2 to 3 year old cattle should be selected. If you choose to eliminate old-age cattle fattening, you should choose large, healthy disease-free cattle to engage in short-term fattening, do not choose sick cattle fattening. Scientific production First, broaden the source of feed fodder is the material basis for raising cattle. The first is to make full use of local agricultural and sideline products for processing and modulation to improve their palatability and digestibility; second is to strengthen grazing and make full use of wild forage resources; third is to extensively cultivate pastures and use forages for silage to reduce feeding costs. Second, shorten the feeding cycle to adopt scientific breeding methods, try to increase the growth of beef cattle, fattening rate, the appropriate amount of slaughter listing, is an effective choice to reduce costs and increase profits. Self-breeding and self-fertilizers should be slaughtered when the cattle are between 1.5 and 2 years old and weigh around 300 kg. The shelf-fat fatteners should be fattened for 3 to 4 months, and the cattle should be slaughtered at a weight of about 500 kilograms. 3. Specialized and moderately-scaled development of specialized cattle-breeding villages and large-scale joint ventures. Through the cattle-raising associations, they can play their advantages in specialized cattle breeding technology, information, marketing, etc., which can overcome the shortage of cows when dispersed and can not attract merchants. The price does not go up, and the drawbacks of cattle being unmarketable. The scale of breeding should not be blindly greed, and the conditions should be suitable. The size of households should be controlled between 30 and 50 to facilitate the operation of funds and reduce the problem of reducing profits due to high interest rates and labor costs. Stevia sweeteners are derived from the leaves of the Stevia rebaudiana (Bertoni) plant, an herbal shrub native to South America. The stevia plant has been used for food and medicinal purposes for hundreds of years, and its leaves and crude extracts have been sold as dietary supplements. Purified extracts of the sweet substances found in the stevia leaf, called steviol glycosides, are considered to be generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA). However, whole stevia leaves and crude leaf extracts are not permitted to be sold as sweeteners in the U.S. because there is not enough toxicological information on these products, according to the FDA. Stevia sweeteners are made by extracting steviol glycosides from the leaves of the stevia plant and purifying them to remove some of the bitter attributes found in the crude extract.
