Effects of concentrate levels on intestinal fermentation and the microbial profile in Japanese draft horses.

In racehorses, feeding a high-concentrate diet could cause abnormal fermentation in the hindgut. This feeding management regime is not suitable for the nutritional physiology of horses. However, studies on the hindgut environment have yet to be reported in Japanese draft horses, so feeding management needs to be investigated in these horses.

- Invited Review - The role of rumen microbiota in enteric methane mitigation for sustainable ruminant production.

Ruminal methane production functions as the main sink for metabolic hydrogen generated through rumen fermentation and is recognized as a considerable source of greenhouse gas emissions. Methane production is a complex trait affected by dry matter intake, feed composition, rumen microbiota and their fermentation, lactation stage, host genetics, and environmental factors. Various mitigation approaches have been proposed.

NO emission factors for organic amendments in Japan from measurement campaign and systematic review.

Organic amendments are important sources of nitrous oxide (NO) emissions from agricultural soils. In 2020, the total amount of N in organic amendments applied to Japanese agricultural soils (440 ktN) was larger than that of synthetic fertilizer (374 ktN). However, NO emissions from organic amendments were estimated by using the country-specific NO emission factor (EF) for synthetic fertilizer (0.

Impacts of Mootral on Methane Production, Rumen Fermentation, and Microbial Community in an Study.

Methane mitigation strategies have a two-sided benefit for both environment and efficient livestock production. This preliminary short-term trial using Mootral (garlic and citrus extracts), a novel natural feed supplement, was conducted to evaluate its efficacy on rumen fermentation characteristics, methane production, and the bacterial and archaeal community. The experiment was performed as a batch culture using rumen fluid collected from sheep, and Mootral was supplemented in three concentrations: 0% (Control), 10%, and 20% of the substrate (50% Grass:50% Concentrate).
