[Influence of the quantity of ingested dry matter and food retention time on feed digestibility in dairy goats].
Simultaneous measurements of organic matter digestibility (OMD) and particulate mean retention time (MRT) of diets containing various proportions of hay and concentrate (bran or beet pulp) were performed in lactating or dry goats. Beyond the hay and concentrate influences, the OMD decreased by 0.5 and 1.3 points as the dry matter intake level increased by 10 g/kg LW0.75 and MRT decreased by 5 h, respectively.
