This study was conducted to evaluate effects of 1000W microwave irradiation for 2.5 and 5 min on
ruminal dry matter (DM) degradation parameters of tomato pomace. Nylon bags filled with 5 g of each of
untreated or microwave treated tomato pomace, were suspended in the rumen of three fistulated Gezel rams
for 0,4,8,12,16,24,36,48 and 72 h, and obtained data were fitted to a non-linear degradation model to calculate
ruminal degradation characteristics. Microwave treatments significantly decreased DM degradability of tomato
pomace only on 0 and 4h incubation times. Although microwave irradiation decreased (p<0.0001) the water
soluble fraction (a) and increased (p<0.05) the potentially degradable fraction (b) of DM, but constant rate of
degradation (c), total degradability (a+b) and effective rumen degradability of DM were not significantly
affected by microwave irradiation. The effect of 5 min irradiation on decreasing water soluble fraction of DM
was higher than that of 2.5 min, but irradiation time can not affect potentially degradable fraction (b). In
conclusion, microwave irradiation reduced DM solubility in the rumen, but has not significant effect on the
extent of total and effective degradability of tomato pomace.
