Effects of supplementing beef cows grazing forages with wheat-based dried distillers’ grains with solubles on animal performance, forage intake & rumen metabolism
… total tract digestibility, and passage rate; rumen fermentation parameters; and the rate and extent of forage degradation were measured. Forage intake, passage rate, and apparent total tract digestibility of DM, NDF, and ADF were not affected (P > 0.41) by treatment. Apparent total tract …

Alternative Feeding Resources in the Mediterranean areas to mitigate methane emissions from sheep
… and productivity both in vivo and at slaughter, rumen pH and fatty acids, rumen microbial ecosystem and in vitro fermentation kinetics. It was found that both carob pup and DCP ingesting animals had similar performance and productivity. The feed conversion ratio (FCR) was 0.25 for all the diets …

Nutrient Impacts on Rumen Growth and Development
… of calf nutrition with a central focus on rumen growth and development. The first study performed used 8 Holstein bull calves to determine if calf starters differing in starch and neutral detergent fiber (NDF) content would affect calf growth, intake, rumen metabolites, blood metabolites, …

The rumen microbial ecosystem during the transition period in dairy cows
Seven rumen cannulated Holstein cows were used from 3 weeks prepartum to 4 weeks postpartum to determine the relative abundance of 7 different species of ruminal microorganisms. The prepartum diet was based on corn silage. In the postpartum, diet included ground corn, grain by-products, and alfalfa …

Effects of supplement type and forage type on ruminal metabolism and diet digestibility of cattle
… corn stover, on diet digestibility and ruminal metabolism of cattle. Ruminally fistulated steers were used in a replicated 4×4 Latin square with a 2×2 factorial arrangement of treatments: 1) hay with a liquid supplement (HL), 2) hay with a dry supplement (HD), 3) corn stover with a liquid …

Effects of clay supplementation on rumen environment, metabolism, inflammation, and performance in dairy cows
… own properties. Clay supplementation effects on rumen, metabolism, and performance have been considered individually among studies. Our objective was to determine the effects of 3 percentages of dietary clay (EcoMix®) supplementation after two different challenges. Challenge one was to induce …
