Edité par CCSD -

Simultaneous measurements of organic matter digestibility (OMD) and mean retention time (MRT) of diets containing various proportions of hay and concentrate (bran or beet pulp) were taken in lactating and dry goats. When the effects of hay and concentrate feeding were ignored, the OMD decreased by 0.5 and 1.3 points resp. as the DM intake level increased by 10 g/kg LW and MRT decreased by 5 h
