Chemical Composition and Digestibility of Dried White and Red Grape Pomace for Ruminants

Latif Zalikarenab, Rasoul Pirmohammadi and Asadollah Teimuriyansari


Due to a shortage of ruminant feeds, especially in developing countries, agro-industrial by products is of important to animal production because they do not compete with human food and also are cheep. The aim of this study was to assess digestibility value dried Grape Pomace (GP) originating from either white or red wine species. The white GP had higher protein, but lower neutral detergent fiber concentration than the red GP. Four mature wether sheep used for determination of digestibility. For measurement of digestibility, GP was mixed with a basal diet and digestibility was considered for the basal diet and test diets containing GP. Animals were allowed 14 day adjustment before a 5 day collection period. The inclusion of GP in the diet significantly decreased the apparent Digestibility of Dry Matter (DMD), Organic Matter (OMD), Dry Matter in Organic Matter (DOMD), Crude Protein (CPD) and Neutral Detergent Fiber (NDFD) (p< 0.01), this decrease were more for red GP than that of white. DMD, OMD, DOMD, CPD, NDFD and content ME calculated by difference for red (and white) GP were 31.64% (38.97%), 30.28% (37.17%), 28.3% (34.31%), 8.61% (35.o1%) and 14.94% (22.39%), 4.53 (5.48) MJ Kg 1, respectively.
