“…Consequently, more organic matters would be preserved, which was consistent with increasing DM content in this study [2,9]. Flieg's score based on the organic acid ingredient was reported as the important evaluation proxy for silage quality, which could indicate the odor characteristic in a way [4,28]. In this study, the LP inoculation remarkably increased Flieg's score (Table 4), and the silage quality was evaluated as "very good".…”

“…Total organic acid (TOA) was calculated using the summation of LA, FA, AA, PA, BA. The silage quality was evaluated using Flieg's score based on the organic acid ingredient (score ≥ 81, very good; 61 ≤ score < 81, good; 41 ≤ score < 61, medium; 21 ≤ score < 41, bad; score < 21, very bad) [4].

“…Vegetable wastes (e.g., leaves of cabbage, cauliflower, and amaranth) and rice straw are two common types of waste generated from consumption of leaf vegetables and rice as important food sources. According to the statistics, 800 million tons of vegetable waste and 900 million tons of crop straw are annually generated from harvesting to sale in China [2][3][4]. Generally, vegetable wastes are highly moist and perishable, while rice straw is dry and degrades slowly.…”

Ensiling has been widely applied to cope with agricultural solid waste to achieve organic waste valorization and relieve environmental pressure and feedstuff shortage. In this study, co-ensiling of cabbage leaf byproduct and rice straw was performed with inoculation of Lactiplantibacillusplantarum (LP) to investigate the effects of inoculation on ensiling performance and microflora profiles. Compared to the control, LP inoculation preserved more dry matter (DM) content (283.4 versus 270.9 g·kg−1 fresh matter (FM) on day 30), increased lactic acid (LA) content (52.1 versus 35.8 g·kg−1 dry matter on day 15), decreased pH (3.55 versus 3.79 on day 15), and caused accumulation of acetic acid (AA), butyric acid (BA), and ammonia. The investigation showed that LP inoculation modified microflora composition, especially resisting potential pathogens and enriching more lactic acid bacteria (LAB) (p < 0.05). Moreover, Lactiplantibacillus and Lacticaseibacillus were identified as the keystone taxa that influenced physicochemical properties and interactions in microflora. They were also the main functional species that directly restrained undesirable microorganisms (p < 0.05), rather than indirectly working via metabolite inhibition and substrate competition (p > 0.05). The results of this present study improve the understanding of the underlying effect of LP inoculation on improving silage quality and facilitate the bio-transformation of cabbage byproduct and rice straw as animal feed.

“…It creates an acidic environment that reduces the risk of feedstock decay and combustion under anaerobic conditions. However, the storage temperature is a critical parameter that significantly affects the silage quality by influencing the microbial community diversity in silages ( Wang Y. et al, 2019 ; Ren et al, 2020 ). In addition, silage fermentation is limited by repeated freezing and thawing low temperatures because not enough lactic acid is produced to ensure the production of good quality silage ( Cao et al, 2011 ; Zhou et al, 2016 ; Dong et al, 2019 ; Wang C. et al, 2019 ; Ren 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.

BACKGROUND With the development of China’s livestock breeding industry, a large amount of waste was discharged and the local environment was seriously polluted. In this research, treatment performance of piggery waste in an ectopic fermentation system (EFS) using different padding materials and safety evaluation of generated organic fertilizer were studied in a pilot experiment. RESULTS During the whole fermentation process, temperature in the EFS fluctuated with addition of fresh feces and its consumption, and the pH value varied between 6.5 and 9.5. The absorption coefficient of pig breeding wastewater and feces per kilogram of padding (maize straw) at the end was 2.52 and 1.88, respectively. Bacteria played a major role in decomposing organic matter, and its number was basically maintained at 107–108 orders of magnitude. The C:N ratio in two EFS beds decreased gradually and was below 14:1 at the end, indicating the maturity of fermentation. Moreover, operation of the EFS with addition of rice husk/coconut shell mixture was more stable than that of EFS with maize straw. After fermentation, the heavy metal, total nutrient content, ascaris egg mortality and fecal coliform population of the generated organic fertilizer from two fermentation beds all met the limits of the Organic Fertilizer Standard of China, and the seed germination index of the product increased. CONCLUSIONS EFS employing maize straw or rice husk/coconut shell mixture as padding material can be used to treat both solid and liquid waste from pig farms. EFS technology reduced the biotoxicity of piggery waste. © 2022 Society of Chemical Industry (SCI).
