Summary: This study evaluated the effects of Bacillus subtilis and Lentilactobacillus buchneri on the fermentation quality, aerobic stability, and microbial communities of corn silage. Inoculation with either strain increased the pH value, acetic acid, and ammonia nitrogen content of the silage, but also resulted in reduced ethanol production and improved fermentation quality. Furthermore, the inoculation prolonged the aerobic stabilization time, attenuated the pH increase, and increased the residues of lactic acid and acetic acid during aerobic exposure. The relative abundance of certain bacteria and fungi, such as Weissella and Kazachstania, were affected by the inoculation.

Summary: The study aimed to investigate the effect of moisture content on microbial communities and metabolites, and found that high-moisture content improved aerobic stability while low-moisture content resulted in higher pH and lactic acid bacterial count during aerobic exposure. Acinetobacter sp. and Candida glabrata dominated the bacterial and fungal communities, with their activities negatively impacting aerobic stability in high-moisture silages. High-moisture silages contained greater total metabolites and various fatty acids and amino acids during aerobic exposure.

Summary: The study investigated the effects of different storage methods on the quality and safety of whole-plant corn silage. Silage bags showed superior preservation of nutrients, fermentation quality, and aerobic stability compared to bunker silos and round bales. Silage bags also had lower levels of mycotoxins after exposure. The microbial communities in the silages varied depending on the storage method, with lactobacillus dominating in the silage bags.

Summary: The objective of this study was to investigate the effect of freeze-thaw condition on oat silage. The results showed that under freeze-thaw condition, the samples had higher pH and lower lactic acid concentration compared to those stored at 20 degrees C. Additionally, freeze-thaw condition limited the fermentation of lactic acid bacteria and severely reduced the aerobic stability of oat silage.

Summary: This study investigated the mechanism underlying the regulation of whole-plant corn silage fermentation by hairy vetch and its impact on silage quality. The results showed that the inclusion of hairy vetch at ratios of 8:2 and 6:4 resulted in higher quality silage. Furthermore, the mixing ratio of the two forage species also affected the bacterial community structure.

Summary: This study evaluated the effects of natamycin, hexanoic acid, and Lactobacillus plantarum on high moisture whole-crop corn silage. The results showed that the addition of natamycin and Lactobacillus plantarum improved lactic acid production during fermentation, while hexanoic acid suppressed lactic acid accumulation. Furthermore, natamycin and Lactobacillus plantarum decreased yeast count and ethanol concentration, and Lactobacillus plantarum also reduced ammonia concentration. Silage with natamycin and Lactobacillus plantarum had lower mycotoxin concentrations, and silage with hexanoic acid showed improved aerobic stability.

Summary: Mixing forage oat with common vetch can increase forage yield, crude protein yield, and resource use efficiency without obvious interspecific competition. The alternate-row mixing system is recommended for supporting the sustainable development of agriculture and livestock production in the arid region of China.

Summary: This study found that replacing corn silage with whole-plant soybean or black oat silage decreased nutrient intake in dairy cows, with OSD decreasing milk and protein yields and SSD increasing rumen ammonia nitrogen concentration. Additionally, the inclusion of SS and OS increased rumination and chewing activities in cows.

Summary: Recently, it has been discovered that adding a certain amount of propionic acid to the silage mixture of barley straw and wheat rye can effectively improve the fermentation quality and effectiveness of the mixture. Studies have also shown that the addition of cellulase and other additives can effectively increase the yield of corn crops. Temperature, precipitation, and the presence of harmful microorganisms like mold also significantly affect the fermentation and aerobic stability of the silage. Addressing the issue of aerobic deterioration has become a crucial concern in the industry.

Summary: The study aimed to screen high 1,2-propanediol-producing Lactobacillus buchneri strains and evaluate their effects on whole-plant corn silage. Two strains, L. buchneri 9-2 and L. buchneri 10-1, showed increased concentrations of 1,2-propanediol and acetic acid in corn silage and improved aerobic stability.

Summary: It has been found that compared to corn straw silage, whole-plant corn silage can improve the growth performance and rumen fermentation of beef cattle. This improvement is achieved by altering the rumen microbiota and regulating the metabolism of amino acids, carbohydrates, and nucleotides.

Summary: The objective of this research was to investigate the effects of different additives on the fermentation quality, aerobic stability, and rumen degradation of mixed silage composed of amaranth and corn straw. The results showed that the addition of different additives could improve the quality of the mixed silage to some extent. The combination of lactic acid bacteria, glucose, and cellulase additives significantly improved the fermentation quality, aerobic stability, and rumen degradation compared to other groups.
