Abstract

The objective of the present study was to determine in vitro dry matter ruminal digestibility (IVDMD),crude protein (lVDCP), neutral detergent fiber (IVDFDN) and acid detergent fiber (IVDFDA) in three different total feed mixes containing sunflower cake extracted by a cold press system. Treatments with five replications, following a fully randomized design were applied: C80V20; C70V30 andC60V40, pelletized total mix feed containing 80:20; 70:30 and 60:40% concentrate: Lucerne hay respectively. No influence of the different concentrations in IVDMS, IVDCP and IVDFDA was detected (P>0.05). However, the only protein source in the concentrate was sunflower cake, which is rich in fat, and must be used according to maximum determined proportions for the different animal classes. Despite the variation found in some components, digestibility of both total mix feeds are indicated for dairy and beef cattle feeding programs.
