Abstract

The purpose of this experiment was to investigate the effects of low dose Lactobacillus plantarum inoculation on fermentation quality, microbial quantity, rumen in vitro gas production characteristics and fermentation quality, microbial quantity after bags opened of whole-plant hybrid Broussonetia papyrifera silage. The experiment was designed as two treatments, CK treatment (without any microbial agent) and LP treatment (inoculated 1×105 CFU/g Lactobacillus plantarum). The fermentation period was 60 days. The results showed as follows:1) compared with the CK treatment, the pH and acid detergent fiber content of LP treatment were significantly decreased (P<0.05), the lactic acid content was significantly increased (P<0.05), the lactic acid bacteria quantity was significantly increased (P<0.05), and the aerobic bacteria quantity was significantly decreased (P<0.05). 2) The organic digestibility of LP treatment was significantly higher than that of CK treatment (P<0.05). 3) The pH on days 0, 4, 8 and 12 after bags opened of LP treatment was significantly lower than that of CK treatment (P<0.05), the acetic acid content and lactic acid bacteria quantity on day 8 after bags opened was significantly higher than that of CK treatment (P<0.05), and the aerobic bacteria quantity on day 8 after bags opened was significantly lower than that of CK treatment (P<0.05). In summary, inoculated low dose of Lactobacillus plantarum to the wrapping whole-plant hybrid Broussonetia papyrifera silage can significantly reduce the pH, acid detergent fiber content and aerobic bacteria quantity in whole-plant hybrid Broussonetia papyrifera silage, increase the lactic acid content, lactic acid bacteria quantity and organic digestibility, and effectively slow down the rise of pH after bags opening.
