This study investigates the effects of three branched-chain amino acids (BCAA; valine, leucine, and isoleucine) on the in vitro ruminal fermentation of wheat straw using batch cultures of mixed ruminal microorganisms. BCAA were added to the buffered ruminal fluid at a concentration of 0, 2, 4, 7, or 10 mmol/L. After 72 h of anaerobic incubation, pH, volatile fatty acids (VFA), and ammonia nitro...

This experiment was conducted to study the effects of various amounts of treated sunflower meal (SFM) with extracted tannins from pistachio hulls on in vitro gas production and ruminal fermentation in ruminants. The SFM was treated with pistachio extract concentrate (PEC), which contained 111.40 g kg-1 total phenol and 71.30 g kg-1 total tannin per dry matter of e...

introduction this study was conducted to evaluate the effect of essential oils of oregano, sweet orange and cumin on chemical composition, parameters of gas production capacity, aerobic stability and degradability of dry matter corn silage carried. secondary metabolites such as essential oils have antimicrobial properties that by adjusting ruminal fermentation in ruminants to improve the use of...

This study aimed to evaluate the effects of twenty species of tropical macroalgae on in vitro fermentation parameters, total gas production (TGP) and methane (CH4) production when incubated in rumen fluid from cattle fed a low quality roughage diet. Primary biochemical parameters of macroalgae were characterized and included proximate, elemental, and fatty acid (FAME) analysis. Macroalgae and t...

abstract efficient use and management of organic matter are important aspects of sustainable agricultural. organic matter is relatively low in majority of soils in iran, and continuous use of n fertilizer would create environmental hazards. therefore, the combined use of n fertilizer and organic wastes is an effective strategy. the purpose of this study was investigating of residual effects of ...

In vitro methods have been standardized and tested to correctly simulate the rumen environment fermentation process. A few studies verified that feed degradability achieved as a result of stirring samples is higher when are incubated under continuous than they only stirred twice daily. The objective this study has verify effect speed on during incubation. For purpose, apparent true dry matter (...

poorly water-soluble drugs often suffer from limited or irreproducible clinical response due to their low solubility and dissolution rate. in this study, organic solvent-free solid dispersions (osf-sds) containing telmisartan (tel) were prepared using polyvinylpyrrolidone k30 (pvp k30) and polyethylene glycol 6000 (peg 6000) as hydrophilic polymers, sodium hydroxide (naoh) as an alkalizer, and ...
