Abstract:

To solve the problem that fecal contamination affects chicken health and contaminates the environment in small and medium-sized chicken enterprises, the study compared the effects of different combinations of bacterial strains and padding material composition on in-situ collection and fermentation of chicken feces, and studied the changes of various indexes during in-situ collection and fermentation of chicken feces. The results showed that the temperature range of in-situ fermentation was 32~60℃. In the in-situ collection of different padding materials, the bacterial cola group showed better fermentation effect than other bacterial combinations. The best effect of nitrogen fixation is A (Ferruginous bacteria) test group. The concentration of total phosphorus in group C (Funong) and Group E (Bacterial cola) reached 31.69% and 16.09%, respectively. C (Funong) and E (Bacterial cola) had the best total potassium enrichment to 9.88% and 12.84%, respectively. In conclusion, the overall fermentation effect of the bacteria cola group is better than that of other experimental groups.

Key words: bacterial strains, chicken manure, in situ collection, fermentation
