“…Previous studies have focused primarily on the effect of additives to P. sinese silages, but little is currently understood regarding the effect of additives on the microbiome of the resultant silage ( Li et al, 2014 , 2018a , 2018b , 2019a , 2020 ; Li L. et al, 2017 ; Wu et al, 2020 ). Currently, only a limited number of studies have examined the effects of additives on the fermentation quality and microbial diversity of P. sinese silage ( Dong et al, 2020 ; Shah et al, 2020 ). It is of note that these studies have focused on specific P. sinese cultivars.…”

This study investigated the fermentation quality of 12 varieties of Pennisetum sinese grown in different regions of Southern China. Following the production of silage from the natural fermentation of P. sinese, the interplay between the chemical composition, fermentation characteristics, environmental factors, and microbiome was examined to understand the influence of these factors on the fermentation quality of silage. The silage quality produced by most of the P. sinese was low; the pH value of the silage was high (4.26–4.86), whilst the lactic acid content was low (10.7–24.1 g/kg DM), with V-scores between 57.9 and 78.3. The bacterial alpha diversities of the 12 P. sinese silages were distinct. There was a predominance of undesirable bacteria (Pseudomonas, Massilia, and Raoultella), which likely caused the poor fermentation quality. The chemical composition and fermentation characteristics of the silage were closely correlated with the composition of the bacterial community. Furthermore, environmental factors (precipitation, temperature, humidity, location) were found to significantly influence the microbiome of the silage. The results confirmed that silage produced from the natural fermentation of 12 different P. sinese varieties had significant variation in their bacterial communities. The difference in environmental factors, due to the P. sinese being grown in various locations across south china, greatly affected the bacterial community found in the silage and thus the fermentation quality. The specific cultivar used for the silage and the environment in which the cultivar is grown must therefore be considered before the initiation of production of silage in order to ensure a higher quality product.

“…In addition, sugarcane presents high lactic acid production and a fast pH drop (Custódio et al, 2016), which also result in lowered natamycin effectiveness during fermentation. Shah et al (2020) reported lower yeast counts in Napier grass silage treated with natamycin for 60 days than in untreated silage. Additionally, the authors reported lower lactic acid levels than those of our silages.…”

“…As observed, silage treated with natamycin showed the lowest N 2 O production as well as the highest protein content. Shah et al (2020) reported lower protein degradation in elephant grass silage treated with natamycin than in untreated silage. It is possible that the presence of natamycin and acetic acid impaired protein metabolization by yeasts.…”

“…It is poorly absorbed in the digestive system of mammals and totally excreted in the feces, making it safe for use in human food and feed (EAEMP, 1998). Recently, Shah et al (2020) reported a low yeast count in elephant grass silage treated with natamycin. Pinto et al (2020) observed the synergistic effect of combining natamycin and LB in corn silages.…”

“…Antifungal supplements are mostly used to hinder the growth of yeasts, fungi, and other undesirable microorganisms to improve fermentation of the silage (Shah et al, 2020b). Yeast has long been considered to be the main microorganism that causes aerobic deterioration in silage because the aerobic deterioration of silage is closely related to the metabolism of the main yeast strain (da Silva et al, 2020).…”

The corruption and/or poor quality of silages caused by low temperature and freeze-thaw conditions makes it imperative to identify effective starters and low temperature silage fermentation technology that can assist the animal feed industry and improve livestock productivity. The effect of L. plantarum QZ227 on the wheat silage quality was evaluated under conditions at constant low temperatures followed by repeated freezing and thawing at low temperatures. QZ227 became the predominant strain in 10 days and underwent a more intensive lactic acid bacteria fermentation than CK. QZ227 accumulated more lactic acid, but lower pH and ammonia nitrogen in the fermentation. During the repeated freezing and thawing process, the accumulated lactic acid in the silage fermented by QZ227 remained relatively stable. Relative to CK, QZ227 reduced the abundance of fungal pathogens in silage at a constant 5°C, including Aspergillus, Sporidiobolaceae, Hypocreaceae, Pleosporales, Cutaneotrichosporon, Alternaria, and Cystobasidiomycetes. Under varying low temperature conditions from days 40 to days 60, QZ227 reduced the pathogenic abundance of fungi such as Pichia, Aspergillus, Agaricales, and Plectosphaerella. QZ227 also reduced the pathogenic abundance of Mucoromycota after the silage had been exposed to oxygen. In conclusion, QZ227 can be used as a silage additive in the fermentation process at both constant and variable low temperatures to ensure fast and vigorous fermentation because it promotes the rapid accumulation of lactic acid, and reduces pH values and aerobic corruption compared to the CK.
