During 2006 and 2007, forages from 3 individual hay harvests were utilized to assess the effects of spontaneous heating on concentrations of fiber components, 48-h neutral detergent fiber (NDF) digestibility (NDFD), and in situ disappearance kinetics of NDF for large-round bales of mixed alfalfa (Medicago sativa L.) and orchardgrass (Dactylis glomerata L.). Over the 3 harvests, 96 large-round b...

Untreated wheat straw (UWS) or ammoniated wheat straw without (AWS) or with (AWSP) a supplement of potato protein of a low rumen degradability was fed to three steers according to a 3 x 3 Latin square design. All rations were supplemented with sugar-beet pulp and minerals. Voluntary organic matter intake (OMI, g/kg0.75 per d) was 67.8, 76.0 and 80.1 for whole rations (51.1, 59.7 and 59.2 for st...

this study was carried out to determine the chemical composition and degradability parameters of dm, adf and ndf in alnus subcordata saw dust (sd) biodegraded by phanerochaete chrysosporium and pleurotus ulmarius fungi. the sd samples were incubated by the fungi at 30 ± 1˚c and 65 ± 5% relative humidity for 7 and 17 days. biodegraded samples were sterilized to constant activity and oven dried f...

This study was conducted using three multiparous non-lactating rumen-cannulated Holstein-Friesian dairy cows, with the objective of evaluating in situ ruminal degradability and fermentation characteristics novel mixtures winter cereal Italian ryegrass (Lolium multiflorum Lam.) plus silages (mixture A: triticale, oats, barley wheat; mixture B: C: oats; D: ryegrass, wheat). The rumen replacing en...

The objectives of this study were to (1) determine the effect exogenous fibrolytic enzyme derived from Trichoderma reesei on dry matter (DM) and neutral detergent fibre (NDF) degradability whole plant faba bean silage (Snowbird), (2) evaluate effects (FETR) DM NDF degradation kinetics silage, (3) compare difference between in vitro approach (DaisyII incubation method) situ assay-biological (nyl...

This study evaluated the change in nutritive value and situ degradability of Desmanthus spp. (desmanthus) cultivars JCU2; D. virgatus, JCU4; bicornutus JCU7; leptophyllus harvested at varying maturity stages to test hypothesis that desmanthus differ between with stage harvest. In Experiment 1, was 11, 38, 72 103 days regrowth (maturity), separated into leaf stem portion, dried analysed for dry ...

samples of salvia leriifolia were collected from khorasan mountains in different growing stages. chemical composition, rumen degradability characteristics of dry matter (dm), crude protein (cp) and neutral detergent fiber (ndf) of salvia leriifolia whole plant (stem and leaves) in different flowering stages and plant leaves in comparison with alfalfa hay and triticale straw were measured using ...

Determining starch degradability is important because of its implicit relation to gut health, ruminal acidosis, energy availability, feed intake, and animal productivity. In vitro assays for protein fiber have been useful tools ration formulation; however, analogous assessments limited update. Our objective was test how an enzymatic in degradation assay compared with the situ technique terms ab...
