during the past two decades, the use of bioplastics as an alternative to regular plastics has received much attention in many different industries. the mechanical and degradable properties of bioplastic are important for their utilization. in this research cellulose of wheat straw and glycerol were mixed by different weight ratios and then reinforced by using date palm fibers. to prepare the bi...

This study was conducted using three multiparous non-lactating rumen-cannulated Holstein-Friesian dairy cows, with the objective of evaluating in situ ruminal degradability and fermentation characteristics novel mixtures winter cereal Italian ryegrass (Lolium multiflorum Lam.) plus silages (mixture A: triticale, oats, barley wheat; mixture B: C: oats; D: ryegrass, wheat). The rumen replacing en...

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 (...

An experiment was conducted to determine the effects of two types of protein, soybean meal (SBM) and ®sh meal (FM); and two types of energy supplements, corn ̄our (CF) and paper pulp (PP) on in vivo digestibility of organic matter (OM), rumen fermentation pattern and dilution rate, rumen microbial-N synthesis and ̄ow of organic matter and nitrogenous compounds through the duodenum in four Merin...

An extensive in vitro study was conducted to delineate the influence of levels and source of sulfur besides rumen fungi habitat on the degradation of pearl millet stover dry matter and fibrous constituents. The results revealed that degradability of dry matter, organic matter, acid detergent fibre, neutral detergent fibre and cellulose from pearl millet stover was maximized (P<0.05), irrespecti...

The effects of supplying increasing ruminal doses of exogenous polysaccharide-degrading enzymes (EPDE) on rumen fermentation and nutrient digestion were studied using eight ruminally cannulated heifers, four of which were also duodenally cannulated, in a replicated Latin square. The heifers were fed a diet of 85.5% rolled barley grain and 14% barley silage (DM basis), and once daily they were g...

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...
