Gas production in bovine feces adding tannins directly or on the diet
ABSTRACT Two experiments were carried out to know the effect of tannin extracts (ET) in gas production. In experiment 1, feces were collected from five bulls (420 ± 10 kg) from the same pen for four consecutive days to have one sample per day, 100 g of the feces were placed in flasks of 600 mL for each sample and the samples were added. following treatments: TE) untreated stool and HT) 7.4% condensed ET. In experiment 2 the following treatments were applied: TES) diet without ET, TC) 0.6% of condensed tannins and TH) 0.6% of hydrolysable tannins to the diet of 18 calves (220 ± 9 kg) for 28 days. In both experiments, the stools obtained were incubated for 24 h to measure their gas production by displacement. The data obtained from gas were compared with Experimental design of random blocks to eliminate the day-sampling effect. In the first experiment, gas production decreased 44% (P <0.001) with tannin extracts added to the feces, but added through the diet, there were no differences between the treatments.
