Short summary
Good reproductive rates presented by the sheep show satisfactory reproductive activity during the two seasons, characterizing good adaptation to the region. The dry season seems to be a season that requires provision of an alternative feed in this critical period, which is characterized by the scarcity of rain and thus the dryness of the pastures.
