Abstract

This study was carried out to determine on the fermentation and feed value of grape pomace. In order to carry out the research the grape pomace taken from Tekirdağ wine factory were ensiled without any additive in plastic container for 45 days. Relating to silage fermentation analysis of pH, ammonia nitrogen, water soluble carbohydrate, organic acids (lactic, acetic and butyric acid) were carried out and microbiological analyses had been done. Digestional value and energy content of crude nutritive matters of grape pomace silage determined with classical digestive experiment. Dry matter, ammonia nitrogen, water soluble carbohydrate, lactic acid, acetic acid content and pH value of grape pomace silage were found as 35.16%, 31.32 g/kg DM, 6.78 g/kg DM, %2.59 DM, %2.36 DM and 3.55, respectively. Digestion coefficients of dry matter, organic matters, crude protein, ether extract, crude fiber and nitrogen free extracts of grape pomace silage were found as 40.85, 39.29, 1.01, 95.36, 22.68, and 46.71%, respectively. The contents of digestible dry matter, organic matters, crude protein, ether extracts, crude fiber and nitrogen-free extracts were found as 408.5, 370.4, 1.1, 111.2, 72.2, and 185.8 g/kg DM, respectively. Metabolisable energy and net energy values of grape pomace silage were found 7.71 MJ ME/kg DM and 4.29 MJ NEL/kg DM, respectively.
