Animal unit weight and daily requirement of Sangsary sheep breed
Sangsary sheep is one of the 27 sheep breeds grazing on rangelands of Iran.Body weight is a suitable index for animal unit determination (Vision,1959,Stoddart et al,1975).Arzani et al (2005) believed that information on forage quality is essential for understanding animal requirements on rangelands.Dry matter requirement depends on grazing season, phenological stage and ratio of plant parts in available forage.The main objective of this research was determination of Sangsary breed unit weight, and its daily dry mater requirement considering forage quality of rangelands in highland and lowland of Semnan province.
