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...

Eight varieties of grain sorghum representing four different seed classes (Waxy, Waxy-BR, Normal, Normal-BR) were wet-milled to study seed composition (percent starch, bran and germ, peripheral endosperm cells-PEC and gluten). Starch recovery was high and similar for all varieties except the Waxy 1126 and Normal-BR ROKY 78. Depression in starch recovery was reflected in the other fractions, par...

chemical composition and metabolizable energy of three camel browsed halophyte species (atriplex leucoclada, suaeda fruticosa, seidlitzia rosmarinus) were assessed and in vitro digestibility of dm (ivdmd), om (ivomd), ndf (ivndfd), adf (ivadfd) were determined using a completely randomized design. plant samples were collected based on camel's grazing patterns during the autumn-winter grazi...

in an experiment, chemical composition, phenolics and fermentation parameters of different parts of raisin co-products (rc) were determined using in vitro gas production with or without polyethylene glycol (peg). different parts of rc included rejected raisins, pedicle, rachis, mixture of raisins, pedicle and rachis, and shekarak (a powder product obtained following sorting of raisins for packi...

Tef grain is becoming very attractive in the Western countries since it is a gluten-free grain with appreciated nutritional advantages. However there is little information of its functional properties and starch digestibility and how they are affected by variety type and particle size distribution. This work evaluates the effect of the grain variety and the mill used on tef flour physico-chemic...

An appropriate in vitro starch digestion model is necessary to comparatively evaluate the digestibility of starch samples and to help predict the in vivo glycemic responses of starchy foods. In the present study, the effect of trypsin and chymotrypsin on in vitro digestion of rice starch was studies for the first time. Inclusion of the trypsin and chymotrypsin in the digestion protocols, to mor...

In vitro digestibility techniques have been developed to predict the apparent total tract digestibility (ATTD) of energy and DE content of mixed diets and feedstuffs including barley grain in swine. However, the techniques have not been tested properly for their accuracy in predicting the variation in ATTD of energy and DE content within wheat grain. The objectives were 1) to compare two 3-step...

background to current knowledge, different oocyte's recovery method and various seasons have profound impact on in vitro embryo production (ivep). objectives the aim of this study was to define an efficient recovery method for oocytes harvesting from slaughterhouse material in different seasons, and their effects on ivep yield. materials and methods ovaries from slaughtered ewes in breeding sea...

this study was done to investigate the nutritive value of festocaovina, agrostisgiganta and avena sativa using sheep rumen and feces liquor as sources of micro-organism through gas production method. rumen and feces liquor were collected from three fistulated sheep. rangeland species sampling was randomly conducted from different areas of guilan province. all the collected samples were initiall...
