Abstract
The article describes the basics of the synthesis of microbial protein in the rumen and the factors which influence this process. Literature data and our own research found that the following factors influence synthesis of microbial protein in the rumen of ruminants: dry matter intake, the role of nitrogen compounds, energy supply from fermentative (enzymic) processes in the rumen, correlation of rough forage to concentrates in feed, environment of the rumen (pH), the rate of passage of forage masses and the duration of presence of forage masses in the rumen, and the role of the vitamins and minerals. A l l these factors have a direct effect on the synthesis of microbial protein in the rumen. Therefore, in this article each factor has separate discussion.

Abstract
Bu makalede rumende mikrobiyel protein sentezinin temelleri ve bu işlemleri etkileyen faktörler tanımlanmaktadır.
Literatür bildirimleri ve kendi yürüttüğümüz araştırmaların sonuçları, aşağıda sıralanan faktörlerin ruminantlarda
rumendeki mikrobiyel protein sentezini etkilediğini göstermektedir: alınan kuru madde miktarı, nitrojen bileşiklerinin
rolü, rumendeki fermentatif (enzimatik) işlemlerden sağlanan enerji, kaba ve konsantre yem arası ilişki, rumen pH'sı,
yem geçiş hızı ve yemin rumende bekleme süresi, vitamin ve minerallerin rolü. Tüm bu faktörler rumende mikrobiyel
protein sentezi üzerine direkt etkilidirler. Dolayısı ile her bir faktör ayrı olarak ele alınmıştır.
