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.
1、Definition: Pig feed is usually composed of protein feed, energy feed, roughage silage feeding materials, minerals, green feed, feed and feed additives; By category: full price, concentrates and premix. 2、Type: Pig has a variety of commonly used feed, according to the nutrition into energy feed, protein feed, roughage, green feed, silage feeding materials, mineral eight kinds of feed and feed additives. 3、About hormone: now basically has added a variety of hormones and antibiotics in pig feed, in order to make the pig meat fast and long lean lean, take a lot of hormone and clenbuterol in feed, in order to pig skin brightness, to add urea and arsenic preparation, in order to pig don't get sick, to add antibiotics and so on. 4、Note: （1）Selection of raw material variety as much as possible raw material variety can have the complementary role of nutrients, but must pay attention to the pig. Nutrient use efficiency in the raw material. （2）The quality of feed ingredients to conform to the standard purchasing raw materials can be in accordance with the national standard, avoid by all means purchasing cheap and inferior raw material. （3）As far as possible the use of local cheap feed raw materials The local feed raw material resources is not the same, some cheap feed ingredients such as rice bran, tofu, can take advantage of, in order to reduce production cost. （4）Feed raw material supply is plentiful For some sometimes no raw material, it is best to avoid using, often because of change the raw material, can cause stress to the pigs. （5）Pay attention to the palatability of feed ingredients Although some raw materials are very cheap, but it isn't palatability, attention should be paid to limit the amount of such materials. On the contrary, for those who are very good palatability raw material, also want to consider to feed restriction, to prevent overeating and digestive problems. （6）Strictly according to the breed standard design recipes, conceptions of avoid by all means Feeding standard were made according to the results of feeding trials, more authoritative standards include the NRC standard, British standard of ARC and the national standard of our country. （7）Mixed evenly Some add less of the raw materials have to be premixed first, and then wait to be added to the aniseed mixed in
Production TuSiLiao need those machines, according to the size of different yield of different is that some of the differences. But it is not a great difference. In general machine has used in the production TuSiLiao: crusher, feed pellet machine, feed mixer, this a few is imperative. There could be other equipment, screening equipment, cooling equipment, all kinds of auxiliary equipment, shaq dragon, blower, belt machine, packaging machine, boiler, etc. 1、Base: play the role of the connecting parts and bearing mill, make them form a whole. Shredded material is being exhausted from the base. 2、Rotor: the main shaft, hammer frame plate, pin shaft, bearings and other parts, hammer, is the main moving parts of crusher. Rotor speed is higher, assembled on without pin and hammer into the dynamic balance test. 3、Operate the door: replace the sieve plate or hammer to open door operation. Crusher work by locks lock door operation, ensure the operation of rotor rotating door can't open on its own. 4、On the chassis: upper feeding mouth, lower connection with base, sieve plate on both sides respectively equipped, and the rotor of the crushing chamber, the material in crushing chamber to smash. 5、Feeding guide mechanism: make the material from the left or right into the crushing chamber. Feeding guide plate of the reversing manual control to ensure the feed direction consistent with the rotor turning. 6、Fixed in powder pressure screen structure: the locking device connected, ensure that screen surface inside the mill. 7、Sieve sieve beam: sieve beam and pressure institutions together to screen piece fixed on the shredder. Production of feed mill adopts double rotor structure, greatly improve the working efficiency.
