Introduction
Interpretation of the core content of the standard
This standard divides compound feeds into three categories: juvenile type (＜5g/tail), fledgling type (5-20g/tail) and growth fish type (＞20g/tail), based on the nutritional needs of yellow catfish (Pelteobagrus fulvidraco) at different growth stages, and formulates differentiated indicator requirements.
Comparative Analysis of Key Indicators
| Project | Fish Juvenile Feed | Young Fish Feed | Growing Fish Feed |
|---|---|---|---|
| Crude Protein≥ | 40.0% | 38.0% | 36.0% |
| Crude Fat≥ | 5.0% | 4.5% | 4.0% |
| Solubility Loss Rate≤ | 10.0%(Pellets) | 3.0% (expanded) | |
Key points of technological innovation
1. Step-by-step nutrition design: Protein demand decreases with the growth stage (40%→36%), which is in line with the physiological characteristics of Pelteobagrus fulvidraco
2. Processing technology differentiation: It is clear that the water stability requirements of extruded feed are stricter than those of pelleted feed (3% vs 10%)
3. Health and safety control: It is mandatory to quote GB 13078 feed hygiene standards and regulate the limits of pollutants such as heavy metals
Implementation and application suggestions
1. Production enterprises should establish a raw material traceability system to ensure amino acid balance (lysine/methionine should be in accordance with GB/T 18246 test)
2. Farms need to pay attention to the storage time: the shelf life of extruded feed is 90 days, which is significantly longer than that of pellet feed 60 days
3. It is recommended to use the SC/T 1077-2004 test method to ensure accurate determination of indicators such as dissolution rate
