Description
In chilean arid and semiarid mediterranean ranges with a rainfall of 250 to 600 mm mainly during fall and winter and with a drought period of six to seven months per year natural pasture develops being the main forage source for sheep production. Productivity level is based on a 70-75 lambing percentage and 0.8-0.9 lambs/ewe/year, equivalent to 25-30 kg/ha/yr (at a stocking rate of 1 ewe/ha/yr). The first objective of this research was to quantify the reproductive and productive potential of Precocius Merino ewes, under intensive system with mating every eight months. The second objective was to study the performance of lambs weaned at different ages and under different nutritional and feeding systems.
