Fermentation characteristics were measured and numbers and distribution by genera of ciliate protozoa were determined in ruminal fluid samples collected from 10 ruminally cannulated steers during the first 30 d of their being fed barley-based diets containing 62% (Medium Barley) or 95% (High Barley) barley grain (DM basis). Ruminal samples were collected at 5-d intervals over the 30-d periods b...

Hydrogen, electric energy production, and metal toxic bioremediation are some of the biotechnological applications sulfate-reducing organisms, which potentially depend on sulfide produced. In this study, offshore Yucatan, capacity to produce hydrogen using microbial consortia from marine sediment (SC469, PD102, SD636) in batch reactors was evaluated. Kinetic tests were characterized by lactate ...

The objective of this study was to determine the effects of l-aspartate, fumarate, l-malate, and an Aspergillus oryzae fermentation extract (Amaferm) on growth on lactate as well as lactate uptake by Selenomonas ruminantium HD4. Growth of S. ruminantium in medium that contained 2 g of dl-lactate per liter was stimulated approximately twofold by 10 mM l-aspartate, fumarate, or l-malate after 24 ...

The aim of this study was to investigate the effects of salinomycin (SL) and feeding on whole body glucose kinetics in sheep fed a high-concentrate diet (25% orchardgrass hay and 75% commercial concentrate). Four adult sheep were fed the diet with or without 20 mg x kg(-1) diet of SL once daily for each 3 wk. The rates of glucose entry and utilization were determined before and during 3 h after...

BACKGROUND Literature is lacking on the effects of feeding by-product feed (BF)-based silage on rumen fermentation parameters, nutrient digestion and nitrogen (N) retention in sheep. Therefore, this study was conducted to determine the effect of replacing rye straw with BF-based silage as a roughage source on ruminal parameters, total-tract apparent nutrient digestibility, and N balance in shee...

The syntrophically propionate-oxidizing bacterium Syntrophobacter wolinii was grown in binary methanogenic coculture with Methanospirillum hungatei as sole partner, free of contaminating Desulfovibrio vulgaris. Substrate tests revealed that S. wolinii could grow also without any syntrophic partner, either with pyruvate as sole substrate or with propionate plus sulfate. Pyruvate was fermented to...

Batch cultures of mixed rumen micro-organisms were used to study the effects of different concentrations of disodium fumarate on the fermentation of five concentrate feeds (maize, barley, wheat, sorghum and cassava meal). Rumen contents were collected from four Merino sheep fed lucerne hay ad libitum and supplemented with 300 g concentrate/d. Disodium fumarate was added to the incubation bottle...

Due to the existence of different races and ethnicities and their different life styles, anatomical structure of people vary from one region of the world to another. The goal of this study is to determine the anterior femoral bowing to length ratio, which can be useful for planning major medical and therapeutic projects as well as designing medical equipment (including nails, orthoses and prost...
