Quality control of fermented feed raw materials

The quality control of fermented feed raw materials mainly includes the following aspects:

1. Appearance and smell of raw materials: check whether the raw materials have peculiar smell, mildew and pollution.

2. Moisture content: Moisture is one of the important indexes for manufacturing fermented feed, and it is necessary to test whether the moisture content of raw materials meets the standard.

3. Nutritional components: It is necessary to test whether the contents of protein, carbohydrate, fat and cellulose in raw materials meet the standards.

4. Detect whether there are harmful substances in raw materials, such as heavy metals and pesticide residues.

5. Detecting the number of microorganisms in raw materials: It is necessary to detect whether the number of bacteria, yeast and mold in raw materials is appropriate to ensure the good microbial flora in the fermentation process.

6. Identify the types of raw materials: ensure that the types of raw materials meet the procurement standards and prevent the use of unknown raw materials.
