Offered Papers Theme A: Efficient Production from Grassland

Description

A deficiency of one or more of the essential minerals in animals can lead not only to a decrease in productivity but also to metabolic diseases in case of severe deficiencies (McDowell, 1985). In general, mineral, especially phosphorous, deficiencies and imbalances are reported from almost all tropical regions of the world (Matijovic & Durackova, 1994). This study was designed to measure the calcium, phosphorous, magnesium, potassium, sodium and chlorine contents of some plant species in the semi-arid rangeland of Chaharmahal & Bakhtiari Province in Iran, because little information is available at present.
