How to choose suitable crayfish feed?

"One look"

1. Look at the color

The color of a certain type of feed is relatively stable within a certain period of time. Since various feed raw materials have different colors and different manufacturers have different formulas, they cannot be measured by a unified color standard. However, when we purchase the same brand, if the color of the feed is wrong or the difference is too large, we should be alert.

2. Look carefully

High-quality feed from regular manufacturers is generally mixed very evenly, with a smooth surface, uniform particles, good pelleting and cooling, and no polarization. It is difficult to ensure feed quality due to poor processing equipment of inferior feed, and there will be a lot of dust, resulting in a lot of waste of feed. Under normal circumstances, this will not happen with good feed. Grab one from different parts of each package of feed. You can compare them and see the difference.

3. Look at the trademarks

Regular manufacturers’ packaging should be beautiful and neat, with clear factory address, phone number, and applicable varieties. There should be trademarks registered with the industrial and commercial department. Registered trademarks should have R on the upper right corner. Label. The factory addresses and phone numbers on the packaging bags of many fake and shoddy products are fake, and they have no registered trademarks. Nowadays, many feed and medicine countries have stipulated that you can scan QR codes and inquire. For regular and good feeds, you can obtain relevant information by inquiry and scanning codes.

4. Look at the production date and raw material composition

Although some feeds are high-quality products produced by regular manufacturers, they will inevitably deteriorate if the shelf life has passed. You should choose products that are tightly packed, dry, loose and have good fluidity. If there is moisture, hardening, or poor color, it means that the product has partially deteriorated and is not suitable for use.

5. See the effect

Compare feeding. There will be a clear contrast between good feed and poor feed after about 40 days of a breeding cycle. Shrimp raised with good feed will have large sizes, good color, and a short growth cycle; poor feed will grow slowly. , the cycle is long, the shrimp sizes are uneven and small.

"Second Smell"

Take a small amount of the sample and put it on your hand. The fishy smell will be strong at first, but gradually becomes lighter or even disappears (this phenomenon is usually caused by the addition of food to the feed). fishy aroma, fishy treasure, fish essence and other flavoring agents instead of fishmeal), there is no fishy smell, and if it lasts a little longer, there will be a sour fermentation aroma. Generally, there is little or no fishmeal in the feed, sour. The sour fermented aroma is the result of fermented soybean meal instead of fish meal. The fishy smell is fishy, ??mellow and long-lasting, which is the normal taste of fish meal. Good feed should have the unique aroma of soybeans, corn and fish meal. Good feed will always maintain the fishy smell of heavy fish meal. Such feed is used The raw materials are authentic.

"Three Soaks"

Generally good crayfish feed will ensure that the feed remains soaked in water for 8-12 hours. This is done to allow the crayfish to eat throughout the night. It maintains the integrity of the crayfish feed. If it is scattered and the feed becomes dregs, it will be difficult for the crayfish to eat. In addition, the nutrients of good feed will not diffuse into the water body within 2 hours. Simply put, the color of good feed will not change after being soaked in the water for about 2 hours. This can ensure that the nutrients of the crayfish feed are basically maintained in the feed. And will not dissolve in water.

"Four Understandings"

Understand the details of after-sales service quality. The after-sales service of feed manufacturers includes their responsibilities for the breeding benefits of the feed and problems caused by the feed itself, as well as the voluntary consultation provided for diseases caused by non-feed factors. Good feed manufacturers will have relatively complete after-sales services and Track
