In this study aimed that the effects of different harvesting times on the nutritional value of barley fodder producing in hydroponic system. Barley fodders were harvested on the 4th, 7th, 10th and 13th days following sowing date. Analysis performed for determining the chemical composition and organic matter digestibility (OMD) and ME content with in vitro gas production technique. It was determined that the DM content was decreased, the CP content was not changed significantly, cell wall contents (NDF, ADF, ADL) and ash content were increased by the maturation of the sprouts. In this study DM, ADF and ash contents were changed significantly (P<0.05). It was obtained that 96 hours cumulative gas production, OMD and ME contents were decreased by the increasing number of harvesting time but the variations were not significant (P>0.05). According to the results, suitable harvesting date was 7th day following the sowing in term of nutritional value of the fodder

Bu çalışma, hidroponik sistemde yetiştirilen arpa bitkisinin besleme değerliliği üzerine farklı hasat zamanlarının etkisinin araştırılması amacıyla yürütülmüştür. Bu amaçla arpa hasılı 4, 7, 10 ve 13. günlerde hasat edilmiş, bitki örnekleri üzerinde kimyasal bileşimin belirlenmesine yönelik analizler ve in vitro gaz üretim tekniği kullanılarak OMS ve ME içerikleri belirlenmiştir. Bitkide hasat gününün ilerlemesiyle KM içeriğinin düştüğü, HP içeriğinde düzenli bir değişim olmadığı, hücre duvarı bileşen miktarı (NDF, ADF, ADL) ve kül içeriğinin arttığı tespit edilmiştir. Çalışmada KM, ADF ve kül içeriklerinin önemli düzeyde değiştiği tespit edilmiştir (P<0.05). Yürütülen in vitro analizler sonucunda ise bitkide 96 saatlik kümülatif gaz üretimi, OMS ve ME içeriklerinin, hasat gününün ilerlemesiyle düştüğü fakat bu düşüşün istatistik açıdan önemli olmadığı tespit edilmiştir (P>0.05). Bu çalışmadan elde edilen bulgulara göre, besleme değerliliği açısından en uygun hasat zamanının 7. gün olduğu sonucuna ulaşılmıştır
