چکیده

this study was carried out to determine the effects of gamma irradiation on dry matter (dm) and on crude protein (cp) degradation of rapeseed meal, using nylon bags and sds-page techniques. ruminal nylon bags of either untreated or irradiated rapeseed meal at doses of 25, 50 and 75 kgy were suspended in the rumen of four non-lactating holstein cows for up to 48 h. intestinal crude protein digestibility was assessed using mobile nylon bag technique. subunits of rapeseed meal proteins and disappearance patterns were traced and determined using sodium dodecyl sulphate polyacrylamid gel electrophoresis and densitometrical scanning. there were significant differences (p

In situ Evaluation of Ruminal Degradability and Intestinal Digestibility of Sunflower Meal Compared to Soybean Meal

The aim of this study was to compare the nutritional value of sunflower meal (SFM) and soybean meal (SBM) protein by determining both its ruminal degradability and intestinal digestibility. Three non lactating Jersey cows fitted with a rumen and T-type duodenal cannulas were used to estimate rumen degradability and intestinal digestibility of SFM and SBM dry matter (DM) and crude protein (CP). ...

Two experiments were conducted to evaluate the effects of microwaving, autoclaving (moist heating), and roasting (dry heating) on gas production parameters and in situ rumen degradability of soybean meal (SBM). SBM was treated by roasting at 140℃ for 30 and 60 min, and at 160℃ for 30 and 60 min, autoclaving at 121℃ for 20 min, and microwaving for 2, 4, and 6 min. A gas production trial...
