Feed quality testing is an important part of feed industry production and product quality management. Excellent feed production enterprises pay great attention to feed testing, and also equipped with professional testing equipment, such as fat analyzer and crude fiber analyzer to improve detection. The effect is to turn off the quality of the finished product. In general, there are 6 routine test indicators for feed testing.
1. Determination of moisture and volatile substances in feed The moisture in feed has an important influence on the quality of feed products. Its content is an important economic indicator, so it is very important to determine feed moisture.
2. Determination of crude protein content in feed Crude protein is a general term for nitrogenous substances in feed. The crude protein content is also an important quality index for evaluating the quality of feed products. It is one of the six routine testing indicators for feed. Currently, the determination of crude protein content in feeds is usually carried out using a protein analyzer.
3. Determination of crude fat in feeds Crude fat is a general term for substances that are soluble in petroleum ether or ether in feed. It is one of the important nutritional indicators of feed products. To determine the content of crude fat in feed, professional fat content can be determined. Fat meter .
4. Determination of crude fiber in feed We know that crude fiber is usually related to digestion. The crude fiber content in the feed will affect the digestion ability of the animal. Therefore, it is good to measure the crude fiber content in the feed by the coarse fiber analyzer. Control its content to ensure feed quality.
5, the determination of crude ash in feed is usually used GB/T 6438-2007 "measurement of crude ash in feed", suitable for the determination of crude ash in animal feed.
6. Determination of calcium in feed Calcium is essential for human growth and an essential element for animals. Generally, the calcium content in the feed does not exceed 1%, while the calcium in the fishmeal and bone meal feeds is 5% to 11%. Through the measurement, the calcium content in the feed can be well controlled, and the feeding quality of the raised animals can be improved.
The above 6 general testing indicators of feed can be measured by professional instruments, and the advantage of using instruments instead of manual testing is that the accuracy is high, the efficiency is high, the manpower is saved, and the artificial error can be effectively reduced. The current professional feed Manufacturers will purchase professional instruments to establish quality inspection laboratories, and at this level of quality testing to ensure product quality.
