ABSTRACT

The effect of rapeseed oil supplementation of wheat straw (WS), wood cellulose (CEL) and Total Mixed Ration (TMR) on the degradation of dry matter, ADF and NDF in the rumen was determined using the in sacco method. Rapeseed oil addition resulted in a significant (p<0.05) reduction of degradation of fibre fraction (NDF and ADF) in the rumen, especially after 6- and 12-hour incubation and significant (p<0.05) decrease of effective (dg) degradability of NDF and ADF in wheat straw and wood cellulose. However, there were no significant (p >0.05) effect of oil supplementation on effective degradability (Dg) of dry matter of all the tested feeds. The differences between control (without oil) and lower level of oil of fat supplementation were much higher than the differences between lower and higher level of oil addition.

Key words: Rapeseed oil, ADF, NDF, TMR, rumen degradation, in sacco..
