Deterjan Lif Sistemi

Öz

Bu makalede yemde lifin (hemiselüloz, selüloz ve lignin) tespitinin geviş getiren hayvanlar (ruminantlar) açısından önemi açıklanmıştır. Yemde ham selülozun tesbiti için kullanılan ve en eski metod olan Ham selüloz (HS) metodu uzun yıllardan beri kullanılmakta olan bir metod olmasına rağmen sadece ham selülozu tesbit ettiği için eksik bir metoddur. Daha sonraki labaratuvar çalışmalarında HS’nin yerini, Van Soest tarafından geliştirilen deterjan lif sistemi almıştır. Bu makalede, nötr deterjanda çözünmeyen lif (NDF) ve asit deterjanda çözünmeyen lif (ADF) özellikleri ve bu analizler yapılırken sonucun değişmemesi için dikkat edilmesi gerekli hususlar özetlenmiştir.

Detergent Fiber System

Abstract

In this paper, importance of feed fiber (hemicellulose, cellulose and lignin) determining for the ruminants were explained. Crude fiber (CF) was the oldest procedure to determine feed fiber, however there were a number of problems with this procedure. Detergent fiber sytem were developed by Van Soest and replaced the CF procedure for feed fiber analyses. In this system, neutral detergent fiber (NDF) and acid detergent fiber (ADF) analyses were used to differentiate feed fiber compenents. Some prequations shold be taken to get better results for ADF and NDF procedures. These prequations were summarized in this paper.
