the effect of three levels (0, 28.65, 57.31mg /200mg substrate) of golpar (heracleum persicum: hp) on in vitro rumen ecosystem and on methane production was assessed. gas production (gp) was recorded from 1 to 54h past of incubation. the parameters studied were in vitro gas production (ivgp), methane production, ammonia-n concentration (nh3-n), in vitro organic matter degradability (ivomde), pa...

nutritive value of winterfat forage (eurotia ceratoides) was evaluated through chemical composition, in situ degradability and in vitro gas production techniques using three permanently fistulated adult baluchi sheep. the cp, ndf, adf, ash, ee and nfc contents of winterfat forage was 19.4, 54.5, 41.6, 9.0, 1.4 and 15.7%, respectively. the leaves had highest cp (27.9%dm) and lowest ndf (40.7%dm)...

Following the extraction of oil for biodiesel production, oilseed press cakes are high in fat. As the dietary supplementation of fat is currently considered the most promising strategy of consistently depressing methanogenesis, it follows that oilseed press cakes may have a similar potential for CH4 abatement. As such, this study aimed to characterise the nutritive value of several oilseed pres...

The feasibility of unconventional feed for ruminants must be analyzed appropriate use as sources energy or protein that contribute to a sustainable production system addressing concerns about climate change, greenhouse gas emissions, and food security. objective this study was evaluate the nutritive value by-products including bean residue (BR), straw (BS), cassava bagasse (CB), corn (CS), oran...

Nanoporous lithium doping magnesium silicate (nl-MS) was introduced into calcium sulfate hemihydrate to prepare calcium sulfate composite (nl-MSC) bone cements. The introduction of nl-MS improved the in vitro degradability of nl-MSC cements, which could neutralize acidic degradable products of calcium sulfate and prevented the pH from dropping. The cements were implanted into the bone defects o...

This study evaluated the in situ ruminal degradability, and subsequent small intestinal digestibility (SID) of dry matter, crude protein (CP), and amino acids (AA) of cottonseed meal (CSM), sunflower seed meal (SFSM) and distillers dried grains with solubles (DDGS) by using the modified three-step in vitro procedure. The ruminal degradability and subsequent SID of AA in rumen-undegradable prote...

this research was conducted to evaluate the effects of electron beam (eb) and gamma ray (gr) radiations at doses of 25, 50 and 75 kgy on ruminal degradation kinetics of dry matter (dm) and crude protein (cp),andin vitro digestibility of canola meal (cm). the nylon bag technique and in vitro two step method were used for this aim. gr decreased ruminal degradability of dm (p<0.05), but eb had no ...

Aim: Present study was conducted to examine the modulatory effect of different essential oils on rumen fermentation pattern in vitro using wheat straw based diet (concentrate: wheat straw 50:50). Materials and Methods: Four essential oils i.e. cinnamon, garlic, oregano and rosemary oils were tested at concentration of 0, 30, 300 and 600 mg/litre (ppm) of total culture fluid using in vitro gas p...
