Eight ruminally cannulated steers (BW = 753 +/- 48 kg) were used to evaluate in situ N, NDF, and DM degradation characteristics of by-product feeds and their application for beef cows consuming low-quality forage. Experimental feedstuffs included (DM basis) 1) extruded-expelled cottonseed meal (ECSM; 33% CP and 55% NDF), 2) extruded-expelled cottonseed meal with linters (ECSML; 25% CP and 41% N...

in this trial, the effect of different levels of echum amoneum (ea) (0.3, 30, 300 or 3000 µl) on in vitro ruminal fermentation characteristics and methane production was assessed. the parameters studied were in vitro gas production (ivgp), methane production, ammonia (nh3-n) concentration, in vitro organic matter degradability (ivomde), partitioning factor (pf) (the ratio of substrate truly deg...

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...

Sixteen ruminally cannulated, English-crossbred heifers (378 ± 28.4 kg) grazing small-grain pasture (SGP) were used in a completely randomized design to evaluate effects of supplementing different amounts of corn dried distillers grains with solubles (DDGS; 0, 0.2, 0.4, and 0.6% of BW; as-fed basis) on forage intake, digestibility, and rumen fermentation characteristics. The experiment was cond...

The aim of this experiment was to investigate the beneficial effect monensin, tannic acid and cinnamon essential oil addition on sesame meal degradability by three-step in vitro method. experimental additives rumen, after rumen whole gastrointestinal tract significant (P<0.05). ruminal intestinal digestibility crude protein with range 76 84% 49 60%, respectively. increased (about 10%). Addit...

This study aims to increase the in vitro ruminal degradability of oil palm fronds (OPFs) through enzymatic pretreatment. The isolated fungi were selected based on their lignocellulosic degrading enzyme activities. Eleven successfully isolated, and activities evaluated. Three fungi, F1, F2 F4 selected, they identified as Trichoderma harzianum MK027305, MK027306 Fusarium solani MK027309, respecti...

This study aimed to evaluate effects of 800 W microwave irradiation for 2, 4 and 6 min on chemical composition, antinutritional factors, ruminal dry matter (DM) and crude protein (CP) degradability, and in vitro CP digestibility of canola seed (CS). Nylon bags of untreated or irradiated CS were suspended in the rumen of three bulls from 0 to 48 h. Protein subfractions of untreated and microwave...
