The DY1 system involved weaning of ewes from their lambs within 24 to 36 hr post-partum and then twice-daily machine milking. In the MIX system, ewes had access to the...

Genetic parameters were estimated for total milk yield of a Sicilo-Sarde flock (INRAT (Tunisian National Institute of Agronomic Research) Experiment Station, Béja) for 881 lactations. Total milk yields were calculated from 8220 bimonthly test day records using the Fleischmann method. Animals included in the relationship matrix were 363 ewes and 83 rams. Estimates were from the use of univariate...
