Two experiments were conducted to determine in situ disappearance of bromegrass hay and a ruminally undegraded protein (RUP) supplement in beef cattle fed restricted amounts of forage. Six Angus crossbred cattle (BW = 589 +/- 44.4 kg; three steers and three heifers) fitted with ruminal cannulas were fed chopped (2.54 cm) bromegrass hay (8.9% CP) at one of three percentages of maintenance intake...

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...

Bioavailability of three rumen protected Methionine (Met) sources with different protection methods (Mepron M85, Evonik Industries, Germany; Methioplus, Soda Nutrition, Italy and Methilock, Tehrandaneh Co. Iran) were evaluated in 2 experiments with 6 canulated non-lactating Holstein cows. In experiment 1, the ruminal in situ and mobile bag techniques were used for assessing ruminal degradabilit...

this research was performed to compare electron beam (eb) and gamma ray (gr) treatments at doses of 25, 50 and 75 kilo gray (kgy) on ruminal degradation kinetics and in vitro digestibility of sunflower meal (sfm). ionizing radiations of eb and gr had significant effects )p

Fifteen different vegetable protein sources found in Pakistan were evaluated for ruminal degradability characteristics through in situ procedure using rumen fistulated Nili-Ravi buffalo steer. Samples of soybean meal, corn gluten meal 60%, maize gluten feed, guar meal, sunflower meal, rapeseed meal, rapeseed cake, canola meal, cottonseed cake, cottonseed meal, coconut cake, coconut meal, palm k...

This study was conducted to evaluate the effect of electron beam irradiation at doses of 250 and 500 kGy on the chemical composition and ruminal dry matter (DM) and neutral detergent fiber (NDF) degradability of wheat straw. Nylon bags of untreated or irradiated wheat straw were suspended in the rumen of three rams for up to 72 h, and resulting data were fitted to non-linear degradation model t...

BACKGROUND Very limited information exists on the ruminal degradation kinetics of nutrients in garlic stalk. The present study aimed to survey the annual yield of garlic stalk in Korea and determine its feed-nutritive value for ruminants. METHODS In Experiment 1, garlic stalk was incubated in situ in the rumen of two Hanwoo steers (360 ± 15 kg body weight) and removed after 12, 24, or 48 h to...

Five ruminally cannulated steers (initial BW = 375 ± 34 kg; ADG = 1.16 ± 0.13 kg) were used in a 5 x 5 Latin square design experiment to determine the effects of increasing urea level on intake, nutrient digestion, nitrogen balance and ruminal kinetics. Isocaloric (NEm = 2.11 Mcal/kg; NEg = 1.35 Mcal/kg) and isonitrogenous (2.24% N) steam-flaked corn-based diets with urea concentrations of 0.0,...

Twenty-five (10 ruminally cannulated) Holstein cows averaging 82 +/- 34 d in milk were assigned to 5 x 5 Latin squares (21-d periods) and fed diets supplemented with one of four different proteins to assess effects on production, ruminal metabolism, omasal flow of N fractions, and degradation rates of protein supplements. Total mixed diets contained (dry matter basis) 44% corn silage, 22% alfal...
