Extract

Manchega (MN) and Lacaune (LC) are two semi-coarse-wooled dairy breeds with similar size but different milk yield, the latter producing twice as much milk as the former (Pérez, 1997). The aim of this experiment was to compare, under the same feed conditions, dry matter intake and performance in late pregnancy and lactation and digestive pools of these two breeds.

Twenty-four ewes, 12 per breed, were used in three different periods: late pregnancy (8 weeks), rearing (5 weeks) and milking (7 weeks). At lambing, average body weight was 74.4 vs 78.5 kg, for LC and MN, respectively. Dry matter intake (DMI), apparent dry matter digestibility (DMD), body condition score (BCS) and milk yield (MY) standardized according to Bocquier et al. (1993) were recorded.
