Yeni Laktik Asit Bakteri İzolatlarının Farklı Kuru Madde İçeriğine Sahip Yonca (Medicago sativa L.) Silajında Mikrobiyel İnokulant Olarak Kullanılma Olanakları

Bu çalışmada, ülkemiz florasından izole edilen L. bifermentans ve L.brevis bakterilerinin, KM içeriği %23.92 olan ve soldurularak %32.97seviyesine çıkarılan yonca materyallerine aşılanmasının silajkalitesine olan etkileri incelenmiştir. Araştırma sonucunda,soldurmanın fermentasyon profili üzerine önemli etkilerinin olduğu,pH seviyesini düşürdüğü ve kuru madde kayıplarını azalttığıbelirlenmiştir. Bakteri aşılamasının ise pH, asetik asit, propiyonikasit ve bütrik asit içeriğini düşürdüğü, laktik asit üretimini artırdığıbelirlenmiştir. Araştırma sonucunda, ham protein içeriği ve laktikasit değerleri dikkate alındığında, yonca silajında soldurma ve L.brevis izolatı ile aşılamanın başarılı sonuçlar verdiği belirlenmiştir.

Using Possibilities of New Lactic Acid Bacteria Isolates as Microbial Inoculant on Different Dry Matter Containing Alfalfa (Medicago sativa L.) Silage

In this study, inoculation effects of two lactic acid bacteria, L. bifermentans and L. brevis, isolated from flora of Turkey, on alfalfa silage containing 23.92% DM (unwilted), and 32.97% DM (wilted) were investigated. Result of the research indicated that wilting effected the fermentation profile significantly by decreasing the pH level and increasing dry matter preservation. Bacterial inoculation decreased the pH level, increased the production of lactic acid, whereas decreased the acetic acid, propionic acid and butyric acid in silage content. L. brevis strain as well as wilting can be used successfully in alfalfa silage production when crude protein and lactic acid production in silage were taken into consideration.
