Comparative example 3
Common chicken feed in market
The selenium-rich yeast contains selenium 2-5 mg/kg.
Experiment 1 assay
TABLE 1
| Evaluation item | Selenium content (mg/kg) | Heavy Metal content (mg/kg) |
| Example 1 | 0.046 | 0.10 |

As can be seen from Table 1, the selenium content of the feed prepared in the examples 1-3 is 0.041-0.046mg/kg (meeting the national standard requirement: < 0.5mg/kg), and the heavy metal content is very low, only 0.08-0.10mg/kg, which will not cause the risk of heavy metal residue or enrichment after the feed is eaten by the livestock; in contrast, in comparative example 1, after only 1 fermentation, the selenium content is obviously reduced to only 0.018mg/kg, and the heavy metal content is relatively low to 0.08 mg/kg; comparative example 2, selenium-enriched yeast and selenium-enriched distiller's yeast are not added, so that the selenium content in the feed is obviously reduced and is only 0.005mg/kg, and the heavy metal content is relatively low and is 0.07 mg/kg; and the comparative example 3 is a conventional chicken feed on the market, the selenium content is 0.002mg/kg, the selenium content is obviously lower, the heavy metal content is 0.59mg/kg, and the heavy metal content is obviously higher, so that heavy metal can be enriched in chicken meat and the like after the chicken feed is eaten for a long time, and the risk of heavy metal pollution or poisoning exists.
Experiment 2 eating experiment
6000 chicks are selected and randomly divided into six groups, each group comprises 1000 chicks, test samples and control samples are respectively fed for 6 times per day, the addition amount is 0.14 percent of the weight of the chicks, the chicks are fed for 30 days, the diarrhea rate, the avian influenza rate and the survival rate are calculated, and the test results are shown in table 2.
TABLE 2
As can be seen from table 2, the feeds prepared in examples 1 to 3 have high selenium content, contain Chinese herbal medicine components, and have good effects on treating diarrhea and avian influenza of chickens, so that the survival rate is very high; in the comparative example 1, after only 1 fermentation, the selenium content is relatively low, and the selenium-rich fermented feed contains Chinese herbal medicine components, so that the diarrhea rate and the avian influenza rate are high, and the survival rate is reduced; compared with the prior art, the feed does not contain selenium-enriched yeast and selenium-enriched distiller yeast, contains Chinese herbal medicine components, has low selenium content in the feed, and causes high diarrhea rate and avian influenza rate, thus reducing the survival rate; and the comparative example 3 is the conventional chicken feed on the market, has no traditional Chinese medicine grass component, has low selenium content, causes high diarrhea rate and avian influenza rate, and has low survival rate.
