Relationship between corn vitreousness and ruminal in situ starch degradability.
The objective of this experiment was to determine the relationship between corn kernel vitreousness and ruminal in situ starch degradation. Fourteen U.S. and five Brazilian corn hybrids cultivated in their respective countries were evaluated. The U.S. dent hybrids were harvested at one-half milk line, black layer, and 21 d after black layer stages of maturity. Brazilian flint hybrids were harve...
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 کاملIn situ evaluation of the ruminal and intestinal degradability of extruded whole horse beans.
Four rumen and proximal duodenum fistulated non-lactating Holstein cows were used to determine the effect of extrusion at 120 degrees C of whole horse beans (Vicia faba cv Talo) on in vitro nitrogen (N) solubility and in situ degradation of dry matter (DM) and crude protein (CP) in the rumen and intestine. Cows were fed a ration of 30% whole horse beans (WHB) and 70% Italian rye-grass hay. The ...
متن کاملSimplified in situ method for estimating ruminal dry matter and protein degradability of concentrates.
In this study, dry matter and crude protein in situ degradation data from different concentrate feeds were used to test the accuracy of effective degradability (ED) measures when using reduced ruminal incubation times compared with models based on seven or eight incubation times. The ED was estimated both with and without correction for nylon bag particle loss. The crude protein ED corrected fo...
متن کاملIn situ evaluation of the ruminal and intestinal degradability of extruded whole lupin seed nitrogen.
The effect of whole lupin seeds (Lupinus albus cv Lublanc) at 120, 150 and 195 degrees C on in situ nitrogen degradability (Dg.N) was measured by the nylon bag technique using fistulated non-lactating Holstein cows. The N degradation was evaluated in nylon bags suspended in the rumen; heating the seeds at 120, 150 and 195 degrees C decreased the Dg.N value: 83.9, 72.9 and 53.0 respectively vs 9...
