Abstrak
Commercially free range poultry farming is a system where birds are given free access to pasture and the accredited Code of Pratice is that they must not be stocked above 1000 birds/hectare. because of the high demand for organic eggs, most free range egg producers in Europe, Australia, Africa and the USA are fully accredited to sell their products organic or free range in the market. Major diffrences were found only with respect to folic acid and vitamin B12 and small but significant variations were found in Ca, Fe and tocopherol concentrations. the higher concentrations of vitamin B12 in the free range and deep litter eggs may possibly have resulted from an increased amount of thisvitamin having been available for absorption from two sources : microbial synthesis within the bird themselves and also from litter or, for the free range bird, from the herbage and soil.
