Özet
Bu çalışma mikrobiyel inokulant ile hazırlanan yonca silajının değişik katkı maddeleri ile birlikte inokulasyon uygulamalarının silaj besin maddeleri ve bazı silaj kalitesi özellikleri üzerine etkilerinin incelenmesi amacıyla planlanmıştır! Deneme'de 4'ü inokulantsız olmak üzere toplam 8 silaj grubu 2x4 faktöriyel deneme düzenine göre oluşturulmuştur. Laboratuvar silosu olarak, yaklaşık 4 kg taze silaj materyali alabilen pet kavanozlardan yararlanılmıştır. Yem katkısı olarak %5 melas, %5 arpa, %1.5 tuz katılmış, inokulantlı gruplarda ise bu katkılara ilaveten her bir silaja Lactobacillus plantarum ve Streptococcus faecium 'dan oluşan bakteri kültürü (Pioneer 1174) ilave edilmiştir. Silolar aynı ortamda 240 gün kapalı tutulduktan sonra açılmıştır. Katkı maddeleri incelenen tüm parametreler üzerinde etkili olmuştur. Buna karşılık inokulant ilavesi KM, HS, NDF, pH, KM kaybı değerleri üzerine etkili olurken HP, ADF ve HK değerlerinde etkisi görülmemiştir. Araştırmada elde edilen sonuçlara göre inokulantların, yem maddelerinin tekniğine uygun olarak silolanması halinde silaj kalitesini artırıcı etkiler sağlayabileceği kanaatine varılmıştır.
This study was designed for investigating the effects of inoculated alfalfa silage with various additives on silage nutrients and silage quality. A 2x4 factorial design was used including 8 silage groups. Of these groups 4 of them are inoculated but rest were left non-inoculated. As laboratory silos, plastic jars that have 4 kg fresh silage material capacity were used. Bacteria cultures (Pioneer 1174; Lactobacillus plantarum and Streptococcus faecium) and additives (5% molasse, 5% barley and 1.5% salt) were added into these silage groups. The silos were stored in the same conditions and were opened after 240 days. We found that inoculation affected dry matter, crude fibre, neutral detergent fibre, pH and dry matter losses, but have no effect on crude protein, acid detergent fibre and crude ash. As a result, it may be concluded that supplementation of inoculant may have beneficial effects on silage quality only if feeds are ensiled with in proper technical conditions.
