this study was carried out to determine the chemical composition and degradability parameters of dm, adf and ndf in alnus subcordata saw dust (sd) biodegraded by phanerochaete chrysosporium and pleurotus ulmarius fungi. the sd samples were incubated by the fungi at 30 ± 1˚c and 65 ± 5% relative humidity for 7 and 17 days. biodegraded samples were sterilized to constant activity and oven dried f...

Conventional (unshredded) and shredded alfalfa hays were heated in either a forced-air oven or a steam pressure cooker at different times and temperatures to determine the effect of heat treatment on chemical composition and ruminal protein degradability. Rates of protein degradation and extents of protein escape were estimated using a ruminal inhibitor in vitro system. Both rates and extents w...

the effects of pre-treating different types of roughages with alkali on the efficacy of exogenous fibrolytic enzymes for improving their digestibility were studied in vitroin factorial arrangement 4 × 3 × 5 (enzyme, treatment and roughage types). two fibrolytic feed enzymes novozyme (n) and celloclast (c) their combination (n+c) were evaluated for their potential to improve in vitrodegradation ...

Emissions of ammonia, as well as other gases and particulates, to the atmosphere are a growing concern of livestock producers, the general public, and regulators. The concentration and ruminal degradability of CP in beef cattle diets may affect urinary and fecal excretion of N and thus may affect ammonia emissions from beef cattle feed yards. To determine the effects of dietary CP concentration...

This study determined the effect of pelagic Sargassum on in vitro dry matter and organic degradation, total gas production (TGP), protozoa population. The treatments were different levels inclusion a basal substrate (Stargrass hay; Cynodon nlemfuensis) as follows: T0 (control treatment based Stargrass hay), T10 (90% hay + 10% Sargassum), T20 (80% 20% T30 (70% 30% Sargassum). Ruminal fermentatio...

Deoxynivalenol (DON) is a type B trichothecene mycotoxin produced by Fusarium fungi. To investigate its ruminal degradability and effect on rumen fermentation, 2 × 5 factorial experiment was conducted in vitro with two feed substrates different forage levels (high (HF), forage-to-concentrate = 4:1; low (LF), 1:4) five DON additions per substrate (0, 5, 10, 15, 20 mg/kg of dry matter). After 48 ...
