Saponins are secondary plant metabolites binding hydrophobic non-sugar components that can reduce ruminant methane (CH4) production. Previous studies revealed tea saponin is one of the common sources saponins used to enteric CH4 However, effect different levels dietary on rumen fermentation remains inconclusive. This study aimed investigate in vitro and production through a meta-analysis approa...

in order to study the effect of different organic fertilizers on quantitative and qualitative characteristics of fenugreek forage, an experiment was conducted based on completely randomized block design with six treatments and three replications at agricultural research station, college of agriculture, ferdowsi university of mashhad, iran, during 2006. the experimental treatments were four orga...

Background: Yeast (Saccharomyces cerevisiae), widely used probiotics, was found to increase the utilization of fiber and improve production in ruminants. The concept chromium (Cr) supplementation has also received a great deal attention since past decade, as Cr could have supra-physiological benefits for domestic livestock. present vitro experiment conducted investigate effect dietary yeast on ...

Reduction in enteric methane (CH4) emissions from cattle can be achieved through use of feed additives, which often results increased emission hydrogen (H2). The objective this study was to investigate vitro effects a known sink, fumaric acid, combination with either 2 inhibitors, the macroalga Asparagopsis taxiformis or nitrate, on CH4 and H2 production, degradability, pH, redox potential. A c...

digestibility coefficient of whole cottonseed was determined by in vivo method and total collection feces. the whole cottonseed degradability was determined by nylon bag method. a number of 12 holstein bulls were used in a complete randomized design. the rations contained zero (control), seven, 14 and 21 percentages of whole cottonseed. during the experimental period, daily gain, dry matter int...

In our study, two-stage anaerobic system was employed to treat high concentration methanol wastewater. The results showed the COD removal efficiency was over 90% at the volume loading of 26.8kgCOD/(m.d) and two-stage anaerobic digestion of methanol wastewater was more efficient and stabler than one stage. The pH of the two UASBs was always lower than 6.0, which wasn’t the suitable condition tha...

BACKGROUND The relationship between the chemical and molecular properties - in particular the (acid detergent) lignin (ADL) content and composition expressed as the ratio between syringyl and guaiacyl compounds (S:G ratio) - of maize stems and in vitro gas production was studied in order to determine which is more important in the degradability of maize stem cell walls in the rumen of ruminants...

the nutritive value of pistachio epicarp (pe) was evaluated by in situ and in vitro techniques. chemical analysis indicated that pe was high in crude protein (11.30%) and low in neutral detergent fiber (26.20%). total phenols, total tannins, condensed tannins and hydrolysable tannins contents in pe were 8.29%, 4.48%, 0.49% and 3.79%, respectively. ruminal dry matter and crude protein degradatio...
