Investigation in terms of digestive values, silages quality and nutrient content of the using pomegranate pomace in the ensiling of apple pomace with high moisture contents

Abstract

The purpose of present study was to determine the quality and in vitro digestion parameters in silages of 100% pomegranate pomace (PPS), 100% apple pomace (APS) and 50% pomegranate pomace + 50% apple pomace (PAPS). The digestion parameters of 10% or 20% using of these silages in total mix ration (TMR) of dairy cattle were researched. The dry matter (DM), crude protein, flavonoids, tannins and anthocyanins of pomegranate pomace were higher than those of apple pomace. Fibrous and non-fibrous carbohydrates of pomegranate pomace were similar to those of apple pomace. The silage DM losses in APS decreased with pomegranate pomace (p =.004). The silage density, gas-methane production, and estimated digestion values of PPS and PAPS were higher than those of APS (p
