Sheep breeding in Sardinia is based on two lambing seasons: in autumn for adult and in late winter for primiparous ewes. The milk production is concentrated within the winter-spring period, determining a break in the cheese factories’ activities from the middle summer to the middle autumn. In order to have a continuous milk production over all the year an out-of-season sheep farming model was tested in Sardinian irrigated lowland. 52 Sarda dairy ewes, 20% of which primiparous, were mated in October with a lambing season in March. The experimental flock grazed rotationally a forage model based on 66% of irrigated surface. Flock fertility and prolificacy resulted 100% and 1.58, respectively. During the suckling period the average lamb growth rate was 255 + 0.08 g head d-1. The average milk yield resulted 279 l head-1in 180 milking days (290 and 258 l head-1for adult and primiparous ewes, respectively). Average milk fat and protein contents were 5.8% and 4.7% respectively. The study suggested that it is possible to integrate an out of season milk production with the traditional breeding system in Sardinian irrigated lowlands.

Abstract

Sheep breeding in Sardinia is based on two lambing seasons: in autumn for adult and in late winter for primiparous ewes. The milk production is concentrated within the winter-spring period, determining a break in the cheese factories’ activities from the middle summer to the middle autumn. In order to have a continuous milk production over all the year an out-of-season sheep farming model was tested in Sardinian irrigated lowland. 52 Sarda dairy ewes, 20% of which primiparous, were mated in October with a lambing season in March. The experimental flock grazed rotationally a forage model based on 66% of irrigated surface. Flock fertility and prolificacy resulted 100% and 1.58, respectively. During the suckling period the average lamb growth rate was 255 + 0.08 g head d-1. The average milk yield resulted 279 l head-1in 180 milking days (290 and 258 l head-1for adult and primiparous ewes, respectively). Average milk fat and protein contents were 5.8% and 4.7% respectively. The study suggested that it is possible to integrate an out of season milk production with the traditional breeding system in Sardinian irrigated lowlands.
