“…Such results are considered desirable because they are below 10% [ 15 ], which indicates no excessive breakdown of proteins to ammonia, characterizing proper silage fermentation. According to Zanine et al [ 16 ], NH 3 -N below 10% is acceptable as it does not cause intoxication and it improves the voluntary intake of silage by animals.…”

Cactus pear is used in large proportions in diets for small ruminants in semiarid regions. However, its exclusive use is not recommended due to the low fiber and crude protein content and the high water and mineral content, leading to metabolic disorders, low dry matter intake, and weight loss. The use of mixed cactus silage associated with protein and fibrous sources seeks to overcome the deficits in dry matter, fiber and crude protein, aiming to improve the nutritional quality of the diets that will be offered to ruminants. Thus, the use of gliricidia hay in cactus pear silages could represent an important alternative to improve the nutritional and fermentative characteristics of the ensiled material. Therefore, our aim was to evaluate the fermentation dynamics, nutritional characteristics, and aerobic stability of mixed silages of cactus pear combined with different levels of gliricidia hay. This was a completely randomized experimental design with five treatments and five repetitions. The treatments consisted of different levels of inclusion of gliricidia hay (0, 10, 20, 30, and 40% on a dry matter basis) in the composition of mixed cactus pear silages. The inclusion of gliricidia hay in the composition of mixed silages of cactus pear resulted in a quadratic effect for dry matter recovery, pH, NH3-N, buffering capacity, aerobic stability, ether extract, P, K, Na, and Zn (p < 0.05). There was a reduction in density, effluent losses, maximum pH, mineral matter, non-fiber carbohydrates, Ca, Mg, Fe, and Mn (p < 0.05), and an increase in the time to reach maximum pH as well as an upward trend in pH, dry matter, organic matter, crude protein, neutral detergent fiber, acid detergent fiber, and B (p < 0.05). Under experimental conditions, the inclusion of gliricidia hay between 20 and 30% in cactus pear-based silage provided an improvement to the chemical composition and fermentation parameters of the silages.

“…Kung Jr. et al (2003) reported the use of urea as an additive cause which increased in the silage pH, resulting in the inhibition of unwanted microorganisms. Zanine et al, (2020) stated that the release of ammonia, due to the use of urea, reduces the growth of yeasts and molds, and consequently, reduces DM losses.…”

The purpose of this study was to evaluate the effects of different proportions of cactus pear mucilage as a moistening additive on chemical composition, ammonia nitrogen, volatile fatty acids, microbial dynamics, fermentation losses, pH, and aerobic stability of corn grains in the form of silage throughout storage periods. The study was carried out in a completely randomized design with a factorial arrangement (5×2), with four replications. The factors corresponded to five forms of moistening for corn grain silage, 0, 5, 10, 20, and 40% of cactus pear mucilage (MA) associated or not with urea (U) in the level of 1.5% of DM. The lowest DM content was found in the silage moistened with 40% of cactus pear mucilage, and the greatest CP content was found in the same treatment but when urea was added. Lower contents of propionic and butyric acids were observed in the silages moistened with 5 and 10% of cactus pear without and with the addition of urea. Dry matter recovery was higher in the treatments with water and 10% of cactus pear. The use of urea affected the LAB population only at 15 d of silo opening, providing a bigger population (6.58 logs CFU g-1) when compared to silages without urea (6.27 logs CFU g-1). The lower concentrations of propionic and butyric acids observed in the silage moistened with 5 and 10% of cactus pear mucilage, regardless of the addition of urea. However, it is recommended to use 10% of cactus pear mucilage without the addition of urea, as it provides better indicators of good-quality silage.

“…N 2 O and NH 3 -N produced through protein decomposition by microorganisms affect the nutritional value of the feed. The decomposition of carbohydrates and proteins can lead to feed losses of up to 10% ( 13 ). In addition, during CH 4 generation, the complex OM is first decomposed into monosaccharides, amino acids, fatty acids, etc., through the hydrolysis-acidification stage.…”

Rice anaerobic fermentation is a significant source of greenhouse gas (GHG) emissions, and in order to efficiently utilize crop residue resources to reduce GHG emissions, rice straw anaerobic fermentation was regulated using lactic acid bacteria (LAB) inoculants (FG1 and TH14), grass medium (GM) to culture LAB, and Acremonim cellulolyticus (AC). Microbial community, GHG emission, dry matter (DM) loss, and anaerobic fermentation were analyzed using PacBio single-molecule real-time and anaerobic fermentation system. The epiphytic microbial diversity of fresh rice straw was extremely rich and contained certain nutrients and minerals. During ensiling, large amounts of GHG such as carbon dioxide are produced due to plant respiration, enzymatic hydrolysis reactions, and proliferation of aerobic bacteria, resulting in energy and DM loss. Addition of FG1, TH14, and AC alone improved anaerobic fermentation by decreasing pH and ammonia nitrogen content ( P < 0.05) and increased lactic acid content ( P < 0.05) when compared to the control, and GM showed the same additive effect as LAB inoculants. Microbial additives formed a co-occurrence microbial network system dominated by LAB, enhanced the biosynthesis of secondary metabolites, diversified the microbial metabolic environment and carbohydrate metabolic pathways, weakened the amino acid metabolic pathways, and made the anaerobic fermentation cleaner. This study is of great significance for the effective utilization of crop straw resources, the promotion of sustainable livestock production, and the reduction of GHG emissions. IMPORTANCE To effectively utilize crop by-product resources, we applied microbial additives to silage fermentation of fresh rice straw. Fresh rice straw is extremely rich in microbial diversity, which was significantly reduced after silage fermentation, and its nutrients were well preserved. Silage fermentation was improved by microbial additives, where the combination of cellulase and lactic acid bacteria acted as enzyme-bacteria synergists to promote lactic acid fermentation and inhibit the proliferation of harmful bacteria, such as protein degradation and gas production, thereby reducing GHG emissions and DM losses. The microbial additives accelerated the formation of a symbiotic microbial network system dominated by lactic acid bacteria, which regulated silage fermentation and improved microbial metabolic pathways for carbohydrates and amino acids, as well as biosynthesis of secondary metabolites.
