Abstract
Ruminal Degradability and Intestinal Digestibility of Dm and Cp in High-Protein Fraction from Sunflower Meal - A Cheap Source of Dietary Protein for Ruminants
Highlights
Sunflower meal (SFM) is a basic and cheap source of feed protein in Bulgaria
We hypothesized that the additional dehulling of SFM will significantly improve its nutritional value
Rumen degradability of dry matter (DM) and crude protein (CP) The DM and CP ruminal degradation parameters and effective degradability values at different outflow rates are presented in Tables 2 and 3
Summary
Sunflower meal (SFM) is a basic and cheap source of feed protein in Bulgaria. According to Mondal et al (2008) rumen CP degradability of SFM at 0.06/h outflow rate was 56%, while Chrencova et al (2010), Diaz-RoyoNr et al (2016) and Nedelkov (2019) reported degradability ranging from 70% to 85%. US Publishers for the rational use of SFM in ruminant nutrition is the higher hulls/fiber content, which decreases both its energy and protein value. There are no data available about the exact protein nutritional value for ruminants of the HPSFM which was the main reason to carry out the present research
