the effect of grape pomace (vitis vinifera) and in oak leaf (quercus libani) tannins by three runs of in vitro gas production on the organic matter digestibility (omd) and in situ dry matter (dm) and crude protein (cp) disappearance were studied in four sheeps. polyethylene glycol (peg) was used to deactivate the tannins. in vitro gas production was recorded at 2, 4, 6, 8, 12, 48, 72, 96 and 12...

Amaranth leaves and seeds are highly nutritious, but less is clearly known for the varieties grown in Tanzania. Grains, (dry fresh) flower part of amaranth were analyzed minerals (iron, zinc, copper manganese), proximate (crude protein, crude fat, fibre carbohydrate) anti-nutrients (nitrate oxalate) content. Minerals significantly higher (p<0.05) fresh leafy performing 75.89 mg/100 g, 3.284 ...

The threat of odors emitted from pork production operations in some areas of the country has restricted growth of the industry and has created negative relations with residential neighbors. Odors from manure result from microbial decomposition of the organic matter and nutrients in undigested feed, and normal exogenous end products of cellular metabolism. Reducing nutrient excretions and contro...

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 ...

to evaluate the yield and quality of barley (hordeum vulgare)–vetch (vicia desycarpa) intercropping, a series of experiments were conducted at the experimental field of the college of agriculture, university of tehran, in karaj (iran) from 2003 to 2005. the ex-periments were arranged in a randomized complete block with a split plot design and four replications. three levels (0, 45 and 90 kg n h...

Using nylon bag techniques, Cornell net carbohydrates and protein systems (CNCPS), scanning electron microscopy, the authors examined digestibility structure of Vicia ervilia (ervil, bitter vetch) after steam flaking, roasting, microwave processing. During in situ technique, samples were incubated at 0, 2, 4, 6, 8, 12, 16, 24, 36, 48 h. For description ruminal DM (dry matter) CP (crude protein)...

A number of analytical methods for constituents commonly measured in distillers dried grains (DDG) are practiced in laboratories serving the agricultural sector. A large interlaboratory variability among results has been observed in the industry. Methods for moisture, crude fat, and crude fiber are empirical, thus part of this variability can be attributed to the use of different methods of ana...
