1) Look at the packaging: The feed product package must be stored, transported, and used in accordance with the requirements for ensuring the safety of the planet's safety. When you purchase, you must check the oldness of the accidental bag and the line of the sewing line. If the appearance is old and rough, the handwriting pattern will fade or blur, indicating that the feed is stored for a long time or the transfer is outdated, or it is a fake product. Do not buy it.
(2) See mark: Feed product should have inspection certificate, label and description The basic contents of f5c label include: trademark, production license team number, product name, feed object, product composition analysis and guarantee storage and raw material composition, net weight, and output The contents of the product specification, such as the date, month, product validity, factory name, site, product standard code, etc., include the product name, call object, usage method, and wishes. As long as the product marking is complete, the product description is true, and there are products with qualified products and registered trademark feed products, the general quality is more reliable.
(3) Quality: When purchasing. It can be used to lift seams and four corners of bags. The feeling inside the bag is not loose, there is a group of phenomena, may be stored for too long or the transport selected by water wet, should not be purchased. At the same time, we should open the package to smell, watch the package, and take the swab. The quality of the feed product is good. When the hand grips forcefully, the powdery material does not form a mass, and the open material has a high hardness, is not easily broken, and is concave and smooth. When the feed is slowly released from the hand, the circulation is good. The granular feed has a crisp sound when it hits the floor. Also, be careful not to buy too much at a time to avoid deterioration after a long storage time.
In addition to the above, the requirements for the purchase of fishmeal are more stringent. The source of fishmeal in the market is complex and the quality varies. Especially for some earthen toners, the protein content is low, the salt content is high, and sometimes even there are adulterants. Fake phenomenon, this type of fishmeal cannot be used. It is better to sample and analyze each batch of purchased fishmeal, which is more reliable.
Polylactic acid (PLA) is a novel biodegradable material made from starch derived from renewable plant resources such as corn. Starch raw materials obtained glucose through saccharification, and then fermentation of glucose and certain strains to produce high purity lactic acid, and then through chemical synthesis method to synthesize polylactic acid of a certain molecular weight. It has good biodegradability and can be completely degraded by microorganisms in nature after use, resulting in carbon dioxide and water, which does not pollute the environment. It is very beneficial to environmental protection and is recognized as an environmentally friendly material. Ordinary plastics are still incinerated, causing a large amount of greenhouse gases into the air, while polylactic acid plastics are buried in the soil to degrade, resulting in carbon dioxide directly into the soil organic matter or absorbed by plants, will not be discharged into the air, will not cause the greenhouse effect.
