Cicer milkvetch (Astragalus cicer L.) is a perennial legume used as a pasture or rangeland plant for ruminants. A study was undertaken to determine whether reported variations in its ruminal digestibility may be related to the presence of an antinutritive material. In vitro fermentation of neutral detergent fiber (NDF) of cicer milkvetch by mixed rumen microflora was poorer than was the ferment...

An experiment was conducted in vitro to determine whether the addition of saponin-containing Yucca schidigera or Quillaja saponaria reduces methane production without impairing ruminal fermentation or fiber digestion. A slightly lower dose of saponin was then fed to lactating dairy cows to evaluate effects on ruminal fermentation, methane production, total-tract nutrient digestibility, and milk...

Abstract Protein digestibility of soybean obtained from the main manufacturing steps for natto, such as soaking (soaked soybeans ‘S’), boiling (boiled ‘B’), and fermentation (fermented ‘F’), was examined in this study. Biochemical indices processed each step those digested fractions by simulated vitro gastrointestinal digestion were also evaluated. The result showed a significant ( P < 0.05)...

This article proposes a methane production approach through sequenced anaerobic digestion of kitchen waste, determines the hydrolysis constants and reaction orders at both low total solid (TS) concentrations and high TS concentrations using the initial rate method, and examines the population growth model and first-order hydrolysis model. The findings indicate that the first-order hydrolysis mo...

We read the recent “Staying Current” article concerning the digestion and absorption of major nutrients by Goodman (2) with great interest and some disappointment. Although we agree with the author that common textbooks tend to gloss over the details, we are far more concerned about the tendency to ignore the digestive role of the colon (5). Considerable amounts (10 –15%) of dietary carbohydrat...

Two feeding trials evaluated several byproducts from commercial amino acid fermentations as N supplements for lactating cows. Trial 1 was a replicated 5 x 5 Latin square that used 2-wk periods and 25 Holstein cows (five with ruminal cannulae) fed diets containing [dry matter (DM) basis] 28% alfalfa silage, 31% corn silage, 28% high moisture ear corn plus 4 percentage units of crude protein (CP)...

Anaerobic digestion with corn straw faces the problems of difficult degradation, long fermentation time and acid accumulation in high concentration feedstocks. In order to speed up process methane production, treated sodium hydroxide was used thermophilic (50 °C) anaerobic digestion, effects biochar addition on performance production microbial community were analyzed. The results showed that cu...

Beverage and Food processing industries are extremely large consumers of energy bio-waste producer worldwide. Due to its high concentration organic compounds, which imposes a biochemical oxygen the waste's breakdown, disposal from these companies in environment increases risk inconvenience ecosystem. In this context, brewing industry's production phases included fermentation vegetable feedstock...

As an important intermediate product, short-chain fatty acids (SCFAs) can be generated after hydrolysis and acidification from waste activated sludge, and then can be transformed to methane during anaerobic digestion process. In order to obtain more SCFA and methane, most studies in literatures were centered on enhancing the hydrolysis of sludge anaerobic digestion which was proved as un-effici...

SCOPE We aimed to investigate the effects of three different soluble pectins on the digestion of other consumed carbohydrates, and the consequent alterations of microbiota composition and SCFA levels in the intestine of pigs. METHODS AND RESULTS Piglets were fed a low-methyl esterified pectin enriched diet (LMP), a high-methyl esterified pectin enriched diet (HMP), a hydrothermal treated soyb...
