4. Colostrum quality detection, quality evaluation and feeding quantity
Test items: colostrum quality of cows
Applicable sample: cow colostrum
Testing conditions: applicable to QC testing of professionals and on-site rapid testing of non- professionals, without special experimental conditionsl
Comparison table of colostrum quality decision:
Refractometer S01 / Brix | LgG,mg/ml | Quality Decision | Hydrometer |
>22% | >50 | Good | green |
20.0~21.9% | 24.9~49.9 | General | yellow |
<19.9% | <25 | Poor | red |
5. Detection of serum total protein content and quality decision
Test item: calf serum total protein
Applicable sample: calf serum
Testing conditions: applicable to QC testing of professionals and on-site rapid testing of non-professionals, without special experimental conditions
Experts have proved through a lot of practice that the critical value of total protein content in calf serum is as follows:
| The calf has probably been dehydrated (the calf has been sick or dehydrated for other reasons) |
| Ideal value |
| Critical value, lower acceptable value |
| Passive immunization failure |
