Evaluation of models to describe ruminal degradation kinetics from in situ ruminal incubation of whole soybeans.
Different mathematical models were evaluated as candidates to describe ruminal dry matter (DM) and crude protein (CP) degradation kinetics of raw and roasted whole soybeans from data obtained using the in situ polyester bag technique. Three models were used: segmented with up to 3 straight lines (model I), negative exponential (model II), and rational function or inverse polynomial (linear over...
متن کاملMorphological diversity of ruminal bacteriophages from sheep and cattle.
Large numbers of bacteriophages (2 x 10(7) to 1 x 10(8)/ml) were present in ruminal fluid from sheep and cattle. Twenty-six distinct types were identified and placed in three morphological groups; several phages possessed unusual structural features. The large numbers and diversity of phages observed indicates a possible role in bacterial lysis and hence in the population dynamics of the rumina...
متن کاملOccurrence of 2-aminoethylphosphonic acid in feeds, ruminal bacteria and duodenal digesta from defaunated sheep.
A quantitative method of analysis for 2-aminoethylphosphonic acid (AEP) was developed using reverse-phase HPLC. The detection limit for AEP was 15 nM, and the detector response (peak area) was linear from AEP levels up to 100 microM (R = .99). Mean recovery of AEP added to strained ruminal fluid from faunated sheep was 98.2%. When AEP was added to a fermentation mixture at a concentration of 22...
متن کاملIn 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). ...
متن کاملECG Changes in Acute Experimental Ruminal Lactic Acidosis in Sheep
For induction of ruminal acidosis, 10 clinically healthy three years old non pregnant female sheep were selected. Prior to the infusion of sucrose (0 hour), rumen and blood samples were obtained in order to determine baseline rumen and blood pH, respectively. Electrocardiogram (ECG) was also recorded. Acute ruminal acidosis was induced experimentally with sucrose at a dose of 18g kg-1 body weig...
