this research was conducted to compare effects of electron beam (eb) and gamma ray (gr) treatments at doses of 25, 50 and 75 kgy on soybean meal (sbm) ruminal degradation kinetics of crude protein (cp) and amino acids (aa). the nylon bag and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page) techniques were used for this aim. ionizing radiations decreased washout and degradati...

effect of electron beam irradiation on degradability coefficients and ruminal- postruminal digestibility of dry matter and crude protein of soybean meal, canola meal and lathyrus sativus seed, irradiated at doses of 50, 100 and 150 kgy was investigated. ruminal degradability of dry matter and crude protein was determined by in situ method using two cannulated holstein heifers. ruminal- postrumi...

Ethanol producers remove lipid from distillers grains (DG) for applications such as biodiesel production. The effects of the lipid removal on ruminal protein degradability and total-tract CP digestibility of DG are not known. Five ruminally and duodenally cannulated Angus-cross steers (BW = 434 ± 15 kg) were used to incubate in situ bags for determination of protein digestibility of low-lipid (...

A study was conducted to characterize the carbohydrate and protein fractions of barley-based distillers grains (BDG) derived from a mix of 70% barley, 20% wheat and 10% rye/triticale. Amino acid composition, ruminal escape protein and amino acid values, and ruminal nutrient degradability of BDG were determined relative to wheat-based distillers' grains (WDG) derived from 100% wheat. On a dry ma...

Wang, M., Jiang, J., Tan, Z.L., Tang, S.X., Sun, Z.H. and Han, X.F. 2009. In situ ruminal crude protein and starch degradation of three classes of feedstuffs in goats. J. Appl. Anim. Res., 36: 23-28. Ruminal crude protein (CP) and starch degradability of three classes of feedstuffs: cereals (maize, wheat, barley, buckwheat, rice, millet and sorghum), legumes (horse bean, soybean, pea and mung b...

Whole soybeans serve as one of the main sources of protein in ruminant nutrition. Different processing methods have been employed for ruminal protein protection. The present study was conducted to determine the effects of microwave irradiation [900 W; 2, 4 and 6 min] on quality, ruminal degradability and estimated in vitro intestinal digestibility of availability soybean crude protein....

Primiparous (n = 9) and multiparous (n = 18) Holstein cows averaging 584 +/- 15 kg of body weight (mean +/- SE) were allotted at 2 wk postpartum to nine groups (3 primiparous and 6 multiparous) of 3 cows each to determine the effects of pea extrusion on ruminal degradability and milk production. Cows were fed a total mixed diet based on timothy silage and concentrate for ad libitum intake. The ...

The objective of this study was to evaluate ruminal degradability and intestinal digestibility of crude protein (CP) and amino acids (AA) in hempseed cake (HC) that were moist heat treated at different temperatures. Samples of cold-pressed HC were autoclaved for 30 min at 110, 120 or 130°C, and a sample of untreated HC was used as the control. Ruminal degradability of CP was estimated, using th...
