5 Inspection rules
GB/T 5915-93
5.1 Sensory index, finished product particle size, moisture content, and crude protein are factory inspection items (delivery inspection items), which are inspected by the manufacturer or the company's quality inspection department. The rest are type inspection items (routine inspection items). 5.2 Under the premise of ensuring product quality, the manufacturer can determine the batch of factory inspection according to the changes in process, equipment, formula raw materials, etc.
6 Determination rules
6.1 Sensory index, moisture content, mixing uniformity, crude protein, crude ash, crude fiber, calcium, phosphorus, etc. are qualified indicators. If one of the indicators does not meet the standard during the inspection, re-sampling should be carried out for re-inspection. If one of the re-inspection results is unqualified, it will be judged as unqualified. 6.2 Digestible energy, crude fat, salt, and finished product particle size are reference indicators. If necessary, they can be tested or accepted according to this standard. 7 Labeling, packaging, transportation, and storage
7.1 Labeling: It should comply with the requirements of GB10648. For feeds with drug additives, the drug name and content should be indicated on the label. 7.2 Packaging, transportation, and storage
The packaging, transportation, and storage of compound feeds must comply with the requirements of quality assurance, quantity assurance, transportation safety, and classification and graded storage to prevent contamination. 39
