Summary: | <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 8.0px Verdana;">The aim of this review was to contribute to the knowledge of neutral detergent fibre (NDF) and non structural carbo-<span style="font: 12.0px Helvetica;"> </span></p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 8.0px Verdana;">hydrate (NSC) requirements in the nutrition of dairy ewes. NDF and NSC requirements were evaluated by analysing a<span style="font: 12.0px Helvetica;"> </span></p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 8.0px Verdana;">dataset that involved 30 experimental trials carried out from 1985 to 2003. The dataset included chemical composition<span style="font: 12.0px Helvetica;"> </span></p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 8.0px Verdana;">of the experimental diets, individual milk yield, body weight, milk protein and fat content. These selected papers regard<span style="font: 12.0px Helvetica;"> </span></p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 8.0px Verdana;">10 different dairy ewe breeds (Valle del Belice, Bergamasca, Comisana, Delle Langhe, Massese, Sarda, Chios,<span style="font: 12.0px Helvetica;"> </span></p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 8.0px Verdana;">Manchega, Lacaune and Friesian) and lactating ewes in mid lactation, kept under non homogeneous environmental and<span style="font: 12.0px Helvetica;"> </span></p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 8.0px Verdana;">feeding conditions.
