High-efficiency concentration material directly supplied to chicken

Abstract

The invention relates to a high efficiency directly supplied concentrated slurry, which is prepared through the following raw materials in the weight percentage that 62 to 68 percent of middle protein soybean meal, 5.5 to 8.5 percent of expanded soybean, 22.8 to 25.7 percent of stone powder and 3.7 to 28.5 percent of premix with a concentration of 1 percent. The concentrated slurry of the invention is directly supplied to the raising households and the comprehensive economic benefits serve as the standard for evaluating the quality of the products. After the concentrated slurry of the invention is practically used, the data indicates that the invention has the following advantages that: (1) the invention perfects the various nutrient demands and sufficiently meets the physical demands during various stages of the chickens cultivated for eggs; (2) the high efficiency raw materials are selected so as to enhance the digestibility of the products; (3) the invention balances the various nutrient demands, enhances the eggshell quality, lowers the leg diseases and death and culling rate, balances the proportions of the calcium and the phosphate and intensifies the stable vitamins and trace elements, and simultaneously brings the theory of the electrolyte balance in the formula. The balanced zwitterions ensure the high-quality eggshells, and paly an important role in playing the production performance of the chick group, lowering the occurrence of the leg diseases and water excretion; (4) the invention provides the healthy nutrients and health-care livestock.

Description

technical field [0001] The invention relates to a feed concentrate for laying hens, in particular to a high-efficiency direct supply concentrate for laying hens. Background technique [0002] After more than 20 years of vigorous development, my country's feed industry has made remarkable achievements. Feed production has been increasing year by year. According to statistics: by the end of 2005, the annual output of concentrated feed in Henan Province alone had reached 2.937 million tons, and the total output reached 7.82 million tons. . While the market is booming, the competition in the feed market has become increasingly fierce. In addition to the outbreak and spread of avian influenza and new epidemics in various places in recent years, the stock of livestock and poultry in the market has decreased, and the demand has shrunk. This has caused various feed manufacturers to compete to lower prices. Take the feed market as an example. The price difference of the same concentr...

Problems solved by technology

While the market is booming, the competition in the feed market has become increasingly fierce. In addition to the outbreak and spread of avian influenza and new epidemics in various places in recent years, the stock of livestock and poultry in the market has decreased, and the demand has shrunk. This has caused various feed manufacturers to compete to lower prices. Take the feed market as an example. The price difference of the same concentrated feed for laying hens during the peak period reaches 10-15 yuan/pack, which shows the difference in product quality. In addition, some small feed companies have weak technical force and poor equipment, resulting in the quality of feed products currently on the market. The good and the bad are intermingled, seriously affecting the production performance of livestock and poultry

[0003] At present, there are problems in the concentrated feed for laying hens in the market: (1) The nutrient composition is complex, the protein quality is poor, and the digestibility is poor, which cannot meet the needs. In order to reduce costs, feed manufacturers use a large number of miscellaneous meal and corn by-product protein substitutes, Such as cotton meal, rapeseed meal, DDG, corn bran, corn germ meal, etc. Although the crude protein of such products can meet the nutritional needs, the protein quality is poor and the digestion and absorption rate is extremely low

(2) The ratio is unreasonable, and laying hens are extremely lacking in energy. Currently, most of the concentrated feeds on the market use a ratio of 60% corn and 40% concentrated feed. After making full-priced feeds, the protein is 15.5-16.5%. , the metabolic energy is about 2580Kcl/Kg, the energy is seriously insufficient, and the egg-to-energy ratio is unreasonable

(3) There are large differences in technical strength and product quality among feed factories. Some small enterprises have weak technical strength, unsound product quality management system, and poor product quality stability.

But similarly, the premix also has its own deficiencies: (1) the proportioning of 5% of the premix takes up a large proportion of the main space, which affects the further improvement of product quality. In the 5% premix, there are 2-3 % is the carrier medical stone and zeolite powder. Even if the recommended formula of pure soybean meal is formulated into full-priced feed, the general crude protein is 16.2-16.5%, and the metabolic energy is about 2650Kcl/Kg, which is comparable to that of laying hens. There is still a certain gap in nutritional needs

(2) The quality of raw materials varies greatly, and the quality is not easy to control. Farmers lack professional knowledge of raw materials, poor abi
