In Vitro Analysis Of Drought Stressed, Chopped Sunflower Heads As A Protein Supplement For Cattle Grazing Corn Crop Residues, D. U. Thomson, R. H. Pritchard
In Vitro Analysis Of Drought Stressed, Chopped Sunflower Heads As A Protein Supplement For Cattle Grazing Corn Crop Residues, D. U. Thomson, R. H. Pritchard
South Dakota Beef Report, 1992
The suitability of drought stressed, chopped sunflower heads as an energy and crude protein supplement to low quality forages was evaluated using in vitro fermentation techniques. Sources of supplemental crude protein used in comparisons were drought stressed, chopped sunflower heads, soybean meal, soybeans, and urea. These crude protein sources were added to cornstalks to produce substrates containing 6, 8, 10, 12, and 15% crude protein. Observed fermentable dry matter was higher than the estimated fermentable dry matters, indicating positive associative effects of crude protein level. Similar differences in observed and estimated fermentable dry matters occurred among soybean meal, soybean, and …
