“…A meta-analysis showed that inoculation with L. buchneri had no consistent influence on ethanol in corn silage (Kleinschmit and Kung, 2006). For corn silages, bacterial inoculants do not appear to result in consistent reductions in ethanol (Hafner et al, 2014(Hafner et al, , 2015.…”

The goal of making silage is to produce a stable feed with a high recovery of dry matter, energy, and highly digestible nutrients compared with the fresh crop. Microbial fermentation in the silo produces an array of end products and can change many nutritive aspects of a forage. High-quality silage should be void of undesirable compounds that could negatively affect animal performance, the environment, or net farm income. This review discusses the interpretation of the common fermentation end products, microbial populations, organoleptic properties, and changes in nutritive aspects of silages during storage of silages with emphasis on a North American perspective.

“…Wide variations in alcohol levels have been observed for different forage, with comparable or lower concentrations seen in corn, alfalfa, cereal and red clover silages [ 3 , 22 , 27 , 28 ]. Current research suggests that a large amount of alcohol is produced during ensilage and that the volatile content of ethanol in corn silage is up to 70% of total VOCs [ 3 , 27 , 28 ], however, in this study, no ethanol was detected at any stage. Except for ethanol, there is a lack of data on alcohols in silage which are probably generated by amino acid catabolism or by the reduction of aldehydes and ketones [ 16 ].…”

“…High ethanol contents have been observed in high-dry-matter grass silages due to their high content of fermentable carbohydrates. Low carbohydrate legume forages do not produce more ethanol during the ensiling process [ 22 , 28 ]. Low fermentable carbohydrate may be the main reason for the absence of ethanol during the MCR fermentation process, while silage quality is not measured by the production of large quantities of ethanol, which can adversely affect both the environment and the animals themselves [ 3 , 27 , 28 ].…”

Enriching the nutritive value of marigold (Tagetes erecta L) crop residues as a ruminant feed by lactic acid bacteria during ensilage

Background Marigold (Tagetes erecta L) accounts for over half of the world’s loose flower production, and marigold crop residue (MCR) are abundantly available and should be used as a forage. In this study, MCR from the last commercial flower pickings was ensilaged with lactic acid bacteria (LAB) and the shift in their volatile organic compounds (VOCs) profiles was monitored. Samples were collected at 6 different times during ensilage (3, 6, 9, 12, 15, 30 days) to determine and quantify the VOCs changes using a solid-phase microextraction (SPME) technique and gas chromatography – mass spectrometry (GC-MS). Results After 30 days, the caryophyllene and piperitone, which account for 14.7 and 12.1% of total VOCs, decreased by 32.9 and 9.6% respectively, alcohols increased from 2.8 to 8.1%, and the acetic acid content increased by 560%. Conclusion We have confirmed LAB can degrade the content of terpenes and enhance the content of alcohols and acids in MCR, which was for the first time on terpene degradation in fodder by ensilage. These results have shed light on our understanding of how to improve fodder odor and to enhance terpene degradation by lactic acid bacteria fermentation.
