Summary

The in vitro gas production technique was used to observe the fermentation characteristics of three feedstuffs (barley, dried alfalfa meal, and dried beet pulp). Inocculum was provided from the caecal contents of suckling rabbits (23, 26, 31 and 35d old) which had access to their dams’ food. Mean OM degradation increased progressively with the age of the rabbits (P<0.01) from 67.4 to 70.8% with inocculum from 23 and 35d kits, and gas production from 302 to 357 ml/g OM incubated (P<0.01). It was confirmed that the in vitro gas production technique is a valid tool for the study the development of caecal microbial activity in rabbits.

Resumen

Resumen

Se observaron las caracteristicas de fermentación de tres alimentos (cebada, hierba médica deshidratada y pulpa de remolacha) a través de la ‘técnica de producción de gas in vitro’, usando como inoculo contenido cecal de conejos lactantes a diferentes edades, 23, 26, 31 y 35 días los cuales tuvieron acceso a la comida de sus madres. De los resultados obtenidos se observa que con el incremento de la edad del animal, fuente del inoculo, se aumenta progresivamente la materia orgánica degradada (67.4 vs 70.8%, respectivamente de 23 y 35 días de edad), y, por consiguiente aumenta la producción de gas (302 vs 357 ml/g de materia orgánica incubada). La técnica de producción de gas in vitro se confirma, por lo tanto, como un instrumento válido por el estudio de la evolución de la actividad microbal en el ciego del conejo.
