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.

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 ability to identify the quality of soybean meal and stone powder, and it is impossible to have professional laboratory equipment to test raw materials, so there are potential safety hazards in raw material quality control , the product quality fluctuates greatly; in addition, the storage conditions of raw materials are poor, such as most of the stone powder is stored in the open air, exposed to wind and rain, mixed with a large amount of sediment, and the calcium content decreases, which seriously affects the quality of eggshells

(3) Nutrients are vulnerable to loss and damage. Due to the small amount of premixed materials, dealers must pick up a certain amount of goods from the factory at one time, resulting in a long storage time

When it is in the hands of the farmers, the trace elements, choline chloride and table salt in the premix are bound to cause certain damage to the vitamins, the physique and immune function of the laying hens will be reduced, and the chickens will be in a sub-healthy state, which will affect the production performance.

[0005] There are also some farmers who prepare their own feed, that is, complete self-batching. Compared with concentrated feed and premixed feed, self-batching can design formula according to the condition of chickens, which can better meet the nutritional needs of chickens, but self-batching is also the same. There are some deficiencies: (1) Lack of professional nutrition knowledge of livestock and poultry. Farmers mix ingredients based on experience. The precision of the formula is poor, the nutrition is not balanced, individual nutrition is excessive, such as the common waste of amino acids, and a large amount of synthetic amino acids are blindly added in breeding. The egg weight is very large, but it causes prolapse of the chickens and increases the death rate, and also shortens the laying cycle of the chickens

(2) The mixing uniformity is poor, the production equipment of the farmers is simple, mostly vertical mixers, and most of the operations are temporary workers, the mixing time and feeding technology are not strictly controlled, the coefficient of variation of the feed is high, the product quality is unstable, and the feeding large difference in effect

(3) There are hidden dangers in the quality of raw materials, and users of self-batching also have the problem that raw materials cannot be checked

(4) High price risk and low breeding income. Farmers generally have limited funds, and it is difficult to purchase raw materials in batches. Affected by fluctuations in raw material prices in the market, product costs vary greatly. Economical and practical, although it looks busy all day, the overall comprehensive benefit is not high
