Isolation and Characterization of Yeasts from Rumen Fluids for Potential Use as Additives in Ruminant Feeding.

is a yeast strain often used to improve the feed quality of ruminants. However, has limited capacity to provide biomass when inoculated with carbon sources and a low ability to produce cellulase enzymes. Here, we hypothesized that yeast in the rumen produces a large amount of biomass and could release cellulase enzymes to break down fiber content.

Effect of yeast-fermented de-hulled rice on in vitro gas production, nutrient degradability, and rumen fermentation.

The aim of this experiment was to test the effect of yeast-fermented de-hulled rice (YDR) levels of protein-rich feed with different kinds of roughages on in vitro gas production, nutrient degradability, and rumen fermentation. The treatments were randomly assigned according to a 2 × 4 factorial arrangement in a completely randomized design (CRD). The two experimental factors were comprised of two roughages (R) (untreated rice straw (RS) and sweet grass hay (SGH)) and four ratios of roughage to yeast-fermented de-hulled rice (R:YDR) (100:0, 75:25, 50:50, and 25:75).

Effects of Supplementation with Royal Poinciana Seed Meal () on Ruminal Fermentation Pattern, Microbial Protein Synthesis, Blood Metabolites and Mitigation of Methane Emissions in Native Thai Beef Cattle.

The object of this present work was to determine the effects of supplementation with pellets containing royal poinciana seed meal (PEREM) on feed use, ruminal fermentation efficiency, microbial protein synthesis, blood metabolites and mitigation of methane (CH) emissions in cattle. The animals used in this experiment were four male Thai native beef cattle () with initial body weights (BWs) of 125 ± 5.0 kg.

Dietary dragon fruit (Hylocereus undatus) peel powder improved in vitro rumen fermentation and gas production kinetics.

Plant phytophenols especially condensed tannins (CT) and saponins (SP) have been demonstrated to impact on rumen fermentation. Dragon fruit (Hylocereus undatus) peel powder (DFPP) contains both CT and SP. The current study aimed to investigate the influence of DFPP and varying levels of concentrate and roughage ratios on gas production kinetics, nutrient degradability, and methane production "using in vitro gas production technique.

Effects of replacing rice bran with tamarind seed meal in concentrate mixture diets on the changes in ruminal ecology and feed utilization of dairy steers.

Feed ingredients costs have been impacting the production cost. Attempts have been made to use local feed resources in order to reduce feed costs. The objective of this study was to identify effect of using crushed tamarind seed meal (TSM) in concentrate mixture on rumen fermentation, dry matter intake, and digestibility of dairy steers.

On-farm feeding interventions to increase milk production in lactating dairy cows.

The objective of this study was to investigate the effect of tropical legume (Phaseolus calcaratus) mixed with ruzi grass feeding on the performance of lactating dairy cows. Eighty-eight lactating dairy cows from 22 smallholder dairy farms northeast of Thailand were assigned to respective dietary treatments according to a Randomized Completely Block Design (RCBD). Four cows were selected from each farm and were allocated into two different feeding groups as follows: ruzi grass and P.
