Bu çalışmanın amacı, bir bakteriyel inokulant, melas ve inokulant+melas kombinasyonunun laboratuvar şartlarında çayır silajının fermentasyon dinamiği ve değişik inkübasyon sürelerinde kuru madde (KM), asit detergent fiber (ADF) ve neutral detergent fiber (NDF)in rumende parçalanabilirliği üzerine etkilerini incelemektir. Biçimden sonra, % 32 kuru madde (KM) içeren taze çayır otu katkılı ve katkısız olarak 1 litrelik cam kavanozlarda silolanmıştır. Deneme grupları, TO: control, T1 : silaj kuru maddesinde 4.7 x 108 cfu kg mikrobiyal inokulant, T2: silaj kuru maddesinde % 5 melas, T3: T1 ve T2 katkılarının kombinasyonundan oluşturuldu. Silolamadan 120 gün sonra mini silolar açıldı ve analiz edildi. Silajlara melas ve melas + inokulant ilave edilen gruplardaki kuru madde miktarı diğer gruplardakinden yüksek bulundu. Katkılar silaj pH’sını düşürürken propiyonik asiti artırdı, laktik asit konsantrasyonunu etkilemedi. Katkılar rumende kuru madde (KM) ve neutral detergent fiber (NDF)’in 96 saatteki parçalanabilirliğini etkilemezken, melas katkılı silaj gruplarının rumende asit detergent fiber (ADF)’in parçalanabilirliğini control grubuna göre artırmıştır.

Anahtar Kelimeler
