Offered Papers Theme A: Efficient Production from Grassland
Description
The principal factors limiting the performance of grazing animals are low protein content of grasses, low energy intake due to high fibre content and mineral deficiencies or imbalances (McDowell, 1985). At least 26 mineral elements are required by at least one animal species (Church et al., 1988). These elements are generally required in small amounts. They have a great deal of importance for body tissue growth as well as for physiological functions. Mineral deficiencies and imbalances have been reported from almost all tropical regions of the world. This study was designed to measure the copper, iron, manganese and zinc contents of some plant species in the semi-arid rangeland of Chaharmahal & Bakhtiari Province in Iran.
