How to judge whether the content of crude fiber in feed exceeds the standard

The moderate intake of crude fibres by animals is advantageous, but excessive or too little intake is detrimental to the body, so animal feed must be properly tailored and controlled. The use of fibers by various animals is to a large extent the decomposition products of microbial enzymes or metabolites of microorganisms. Fiber is an essential nutrient for ruminants. The main role includes the following aspects: 1. Maintain the normal function of the rumen and animal health; 2. Maintain normal animal production performance; 3. Provide a lot of energy for animals. The measurement of the crude fibre content of the feed can be performed using a fiber gauge, and the fibers we know include cellulose, hemicellulose, pectin, lignin, β-glucan, arabinoxylan, etc. The instrument is sometimes called a coarse fiber analyzer. After measuring the crude fiber content by using a fiber tester, it is the best method to formulate a reasonable course, but it is also possible to check whether some of the animal's feed has excessive crude fiber content by looking at some animal reactions.

Through the evaluation of the hardness of the feed, feed pellets made with pellets, if the hardness is low, the crude fiber content is low, soft and unformed as the crude fiber content is too high, not soft and not hard, but the moderate fiber content is moderate. For rabbits, you can also judge whether the crude fiber content in rabbits' feed has exceeded the standard in several other ways: 1. Look at the feces. The feces of adult rabbits should be of a size such as peanuts and have a smooth appearance. If the feces is dark and small, the crude fiber content is low, and if the yellow is too large, the crude fiber content is too high. 2. To see if the rabbit eats wool and cages. Young rabbits and young rabbits have a clean, white coat that is a balanced diet. If you regularly eat rabbit hair and lick the cage, it may be that the crude fiber content in the feed is too low. 3. Look at the lyrics. Rabbits with medium sensation, without fat or body weight, are suitable for crude fiber; those with excessive sensation are those with low crude fiber content; those who are too lean have high crude fiber content.

The above is to judge whether the rabbit feed exceeds the standard or not, and for each different animal, it can also judge with some of its own reactions. However, the best method of measurement is to use a fiber meter to determine the appropriate amount of the animal after the measurement.
