Summary: | Two experiments were performed to determine the influence of (TE) tannins extract addition on gas
production from beef-cattle feces. Experiment 1: fecal samples collected during four consecutive days from
five bullocks placed in a pen, and an integrated pull sample/day. 100 g of feces was placed in 600 ml flasks,
in a randomized complete block design into treatments: 1) Feces without TE addition (Control), and 2)
Addition Dry Matter Basis (DB) with 7.4% of condensed TE (CT). In the second experiment, eighteen calves
in a complete randomized block design were used treatments were: 1) diet without TE (Control), 2) Control
plus 0.6% DB of CT, and 3) Control plus 0.6% DB of Hydrolyzable TE (HT) on a 28 days diet. Total of feces
was incubated for 24 h in vitro, then gas production was measured, and the results analyzed by ANOVA.
CT addition decreased by 44% gas production (P<0.001). The TE addition does not modify gas production
(P>0.50); results indicate that gas production decreases with the addition of TE on bovine feces, but, does
not when TE is included in the diet
Se realizaron dos experimentos para conocer el efecto de los extractos de taninos (ET) en la producción de gas. En el experimento 1 se colectaron heces de cinco toretes (420 ± 10 kg) de un mismo corral durante cuatro días consecutivos para tener una muestra por día, 100 g de las heces se colocaron en frascos de 600 mL para cada muestra y se adicionaron los siguientes tratamientos: TE) heces sin tratar y HT) 7.4% de ET condensados. En el experimento 2 se aplicaron los siguientes tratamientos: TES) dieta sin ET, TC) 0.6% de taninos condensados y TH) 0.6% de taninos hidrolizables a la dieta de 18 becerros (220±9 kg) durante 28 días. En los dos experimentos las heces obtenidas se incubaron durante 24 h para medir su producción de gas por desplazamiento. Los datos obtenidos de gas se compararón con Diseño experimental de bloques al azar para eliminar el efecto día de muestreo. En el primer experimento la producción de gas disminuyó 44% (P<0.001) con los extractos de taninos adicionados sobre las heces, pero adicionados a través de la dieta no hubo diferencias entre los tratamientos |
