The corn tablet manufacturer explains the advantages and disadvantages of feed identification skills

All plant, animal and mineral substances that can supply livestock and poultry to feed, digest and absorb nutrients and have harmless effects are collectively referred to as feeds. As the saying goes, "Food is the most important thing for people and material is the most important thing for livestock". Feed can not only maintain the life of livestock and poultry, but also determine the productivity of animal husbandry. Only qualified feed can ensure the healthy growth of livestock and poultry. The current corn flake manufacturer introduces the identification methods of good and bad feed as follows for the reference of the majority of farmers.

1. Look at the trademark.

For the feed produced by regular manufacturers, the product package has a label approval certificate number, a label code, and a trademark registered by the industry and commerce department. The top right of the registered trademark is printed with the "R" sign, and the package is beautiful and tidy, with clear factory address and telephone. The package of fake and inferior feed is rough. The factory address and telephone number on it are false, and there is no registered trademark.

2. Look at the date.

The breeder shall purchase the feed within the shelf life to feed the livestock and poultry. After the shelf life, the feed will inevitably deteriorate. Even if it is well preserved, the content of vitamins and other nutrients in the feed will decrease after oxidation, affecting the feeding effect. In addition, the feedstuff purchased by farmers should also be fed within the shelf life.

3. Look at the color.

Check whether the color of the feed is consistent, whether it contains impurities, and whether the raw materials are mixed evenly. When purchasing the same brand of feed, attention should also be paid to the large change in color of successive batches of feed. The general feed color is yellow, indicating that the proportion of corn and soybean meal is large; When the color is dark, the proportion of fish meal and rapeseed meal is large.

4. Look at the particles.

The feed produced by regular feed manufacturers is well mixed, pelleted and cooled, so the feed surface is smooth and the particles are even. Poor quality feed is difficult to ensure the quality of feed granules due to the simple processing equipment.

5. Smell.

A good concentrated feed should have a pure fishy smell, without odor or other peculiar smell; The inferior feed has a putrid smell or essence smell (essence is added to cover the musty smell of deteriorated raw materials). Therefore, although some feedstuffs are particularly fragrant, they are not good feedstuffs. Good feedstuffs should have the flavor of soybean and corn.

6. Touch.

Grab a handful of feed and squeeze it with force. If it does not loosen, it indicates that the feed contains too much water, and it is easy to become moldy and deteriorated when stored; You can also insert your hand into the feed. If you feel the feed is hot, it indicates that the feed has started to mildew.

7. Listening.

When the fresh and dry feed is stirred, it is loose without caking, with good fluidity and clear sound; On the contrary, if the water content is high, the moldy and inferior feed will have no sound or dull sound.
