The concept of small make up know feed

According to our country feed standard definition (GB10647-89), can provide nutrients needed for breeding animals, guarantee the health, promote the growth and production, and the harmful effect does not occur under the rational use of feeding material, called the feed. The author believes that its provide nutrients should have a certain amount of concepts, not all can provide the nutrients can be feeding material is feed. Although such as sawdust, rice husk contains nutrients, but it can't meet the needs of the animals normal growth or production of nutrients, therefore it cannot serve as animal feeding material. Again, such as wheat straw, rice straw all contains a certain amount of nutrients, can also be plant-eating animals, such as cattle, sheep, horse) part of digestion and under the condition of reasonable collocation with other feed, can meet the needs of the plant-eating animal nutrition, so it can be used as a herbivore feeding material. And the nutrients in the wheat straw, rice straw are difficult to pigs, chickens and other omnivores disappear, and is not consistent with what the animal digestive tract volume on the volume, so not as pigs, chicken feed, can only be used as a filling material, even as a filler to pledge, also should pay special attention on adding amount. With the development of bar material industry, many nutrient substance also delimit feed category is not available, such as antibiotics, anti caking agent, insecticide care agent such as nutritional additives.

The development of feed machinery in China

At present, the widespread adoption of feed processing machinery, productivity is not high, such as domestic puffing machine maximum output of 3 tons ~ 5 tons/hour, has a certain gap compared with abroad. In terms of the development of feed processing machinery, the United States and Europe is ahead, stand-alone equipment automation and complete sets of equipment automatic control program is higher. Feed machinery industry in our country should be the direction of large-scale, intensive, by expanding sales to reduce the production cost and management cost, improve efficiency. Mill in China should further make a breakthrough on load control technology, and the central control technology combination, realize the grinder completely simulate the working state of each; Developed a safe and reliable automatic screen institutions change, make the mill in the case of non-stop automatic in screen, reduce downtime, facilitating the production of different materials, improve efficiency. Mixer mainly in discharge uniformity of detection, automatic detection of leakage, after mixing of automatic cleaning aspects to do further research, and to study particle machine conditioning time control technology for the material, such as the different material, conditioning automatically adjust Angle, change the residence time of a material on or through the conditioning implement automatic adjustment of the blade Angle to implement, etc.; To develop a dynamic automatic feeder roller pressure, ring die clearance adjusting mechanism, the particles on the access of feed material pulverization instrument equipment, and to achieve timely control, acceleration feedback speed, improve the quality of products. In today's China need to increase the investment in the enterprises, expand the basic research. From the point of feed machinery industrial development scale good countries, many famous feed machinery manufacturers, have their own research institutions or scientific research institutions and the relevant research of cooperation, the most advanced, most of the cutting edge of technology in the enterprise hands, they have a strong development momentum and competitive forces. As a result, China's feed machinery manufacturing enterprises to participate in international competition, must increase investment in scientific research, basic research for the development of frontier. Can adopt the method besides enterprise self-built research institutes, and the relevant scientific research institutions, colleges and universities, and even other relevant scientific research departments of industry is very necessary, also is feasible. Through this kind of a wide range of cooperation, take out the advanced product, enhance the competitiveness of the enterprises in the international market.
