Abstract
The present study was conducted to assess the capability of dietary oils with high degree of
unsaturation to act as "sinks" for absorption of bio-hydrogen of the rumen. Three fat capsules of
different oils [soy (T1), sunflower (T2) and mustard (T3)] were fed to treatment groups along with
control (T4). The total fat concentrations (mg/ml serum) were similar in all the treatment groups
throughout the experiment. Per cent FFAs was higher in T.1 than in T2 while T3 and T4 were similar.
The iodine number was higher in T1 and T groups while 1 3 and T4 tended to similar. DMI (kg/day)
was higher in T4 followed by T3, T; and T2• Digestibility of crude protein differed significantly (P<0.5)
and had influence on fiber digestibility. Average body weight gain tended to be higher in T2' followed
by T1, T3 and T4 (lowest).
