Description
The objective was to determine the effect of protein degradability and supplement level on forage degradation. Steers fistulated were utilizated in brachiaria (Brachiaria brizantha) pasture. A randomized block design was used with a control treatment and supplements according to a factorial scheme combining low, medium and high protein degradability with supplementation levels: low, medium and high analysed as principal treatments and incubation time as splitplot by SAS. Nylon bags were incubated at 4; 8; 12; 24; 48; 72; 96 and 120 hours to determine DM, CP and NDF degradation. There was no effect (P>0.05) of protein degradability and supplementation levels on ruminal degradation being not different (P>0.05) from control. The exponencial model indicated that 29% of CP constituted the soluble fraction and the insoluble potentially degradable was 50% with degradation rate of 4.15%. Concerning the NDF 57% was potentially degradable at a rate of 4.02%.
