Forage conservation is a neglected nitrous oxide source.

Agricultural activities are the major anthropogenic source of nitrous oxide ( ), an important greenhouse gas and ozone-depleting substance. However, the role of forage conservation as a potential source of has rarely been studied. We investigated production from the simulated silage of the three major crops-maize, alfalfa, and sorghum-used for silage in the United States, which comprises over 90% of the total silage production.

Effects of inoculation of corn silage with Lactobacillus spp. or Saccharomyces cerevisiae alone or in combination on silage fermentation characteristics, nutrient digestibility, and growth performance of growing beef cattle.

This study evaluated the effects of a novel silage inoculant containing Saccharomyces cerevisiae strain 3 as a direct fed microbial (DFM) on the ensiling, aerobic stability, and nutrient digestibility of whole-crop corn silage and growth performance of beef cattle. Treatments included uninoculated corn silage (CON) or corn silage inoculated with a mixture of 1.1 × 105 cfu g-1 fresh forage Lactobacillus plantarum and Lactobacillus buchneri (INOC1) or 1.

Impact of Saccharomyces cerevisiae and Lactobacillus buchneri on microbial communities during ensiling and aerobic spoilage of corn silage1.

The objective of this study was to assess the impact of Saccharomyces cerevisiae in combination with Lactobacillus buchneri on the fermentation characteristics, aerobic stability, nutritive value, and microbial communities of corn silage. Whole crop corn (39% DM) was either uninoculated (Control) or inoculated with S. cerevisiae and L.

Construction and use of a computerized DNA fingerprint database for lactic acid bacteria from silage.

Efficient selection of new silage inoculant strains from a collection of over 10,000 isolates of lactic acid bacteria (LAB) requires excellent strain discrimination. Toward that end, we constructed a GelCompar II database of DNA fingerprint patterns of ethidium bromide-stained EcoRI fragments of total LAB DNA separated by conventional agarose gel electrophoresis. We found that the total DNA patterns were strain-specific; 56/60 American Type Culture Collection strains of 33 species of LAB could be distinguished.
