Look at the date: During the warranty period, the manufacturer is responsible for the quality of the product. The farmer should make the user's product within the warranty period. It is difficult to meet the growth needs of animals beyond the shelf-life of feeds, vitamins, and other vulnerable nutrients. And the factory will not be responsible for the economic losses caused by the use of the warranty period. Although some feeds are quality feeds produced by regular manufacturers, if they exceed the shelf life, the feeds will inevitably deteriorate. Even if they are well-kept, the efficiency of nutrients such as vitamins in the feed will be reduced, affecting the feeding effect. The purchase of feed should also be noted that the best-purchased feed can be fed within the shelf life.
Look at the particles: regular manufacturers of high-quality feed mix are very uniform, there will be no polarization phenomenon, poor quality feed because of the processing equipment is simple, it is difficult to ensure the quality of feed. Grab a handful of different parts of each pack for comparison, it is easy to see the difference in appearance. The surface is smooth and the particles are even, which means that the granulation and cooling are good.
Smell smell: good concentrate should have a relatively pure fishy smell, not odor or other odors. Some inferior feeds add a higher concentration of flavor in order to mask the musty smell of some deteriorating materials, so some feeds, although particularly fragrant, are not good feeds. Good feed has the unique flavor of soybeans and corn.
See trademark: Different manufacturers have different label approval numbers. The label identification number indicates that the label has been reviewed and registered by the relevant provincial administrative department and complies with the relevant national regulations. The standard code is the standard that the manufacturer produces. The implementation standard specifies the requirements for the product, test methods, inspection rules and signs, packaging, transportation, and storage. The regular manufacturer's packaging should be beautiful and neat, and the factory site, telephone, and adaptable species should be clearly defined, and there should be trademarks registered in the industry and commerce departments. Many counterfeit and shoddy products on the bags and on the telephone are false, and there are no registered trademarks. The registered trademark has an R mark on the upper right.
Buy feed 5 methods
Look at the color: generally the same brand or the same kind of feed in a certain period of time the color is relatively stable, but because of a variety of feed ingredients are not the same color, different manufacturers have different formulations, and can not be measured with the color standard . When we buy the same brand of feed, we should be vigilant if the color changes too much. The general color of yellow indicates that the proportion of corn and soybean meal is relatively large, and the deep color indicates that the proportion of fish meal, rapeseed meal and cottonseed meal is relatively large.
