Abstract

In this study, whole-crop barley planted in Autumn-winter as second crop for giving an opportunity planting of main crop was harvested at boot stage at the begining of spring. Barley was chopped into 1.5-2 cm pieces and divided into groups as follows: Y (unwilted) group, ensiled as fresh on harvest day, P (wilted) group, ensiled after wilting 24 h, Y+S (unwilted material 87% + Straw 13%) group, ensiled after harvest without wilting and added straw with treated HCI. The changes in nutrients cotent of silages and in vitro digestibility of dry matter were investigated. Dry matter, crude protein, eter extract, crude fiber and acid detergent fiber contents increased graeter in silage groups as compared in fresh materials. However, nitrogen free extract and neutral detergent fiber contents decreased. Dry matter and nitrogen free extract contents were not different in P and Y+S groups, but the lowest values were determined in Y group (P0.05) in fresh material. The invitro digestibility of dry malter of silages was determined 60.63, 64.32 and 62.24% in Y, P and Y+S groups, respectively. The difefernces were statistically significant between groups (P
