THE EFFECT OF DIETARY HUMIC-ALUMINOSILICATE PREPARATION ON THE CONTENT OF CADMIUM AND LEAD IN MUSCLE AND LIVER OF HENS HOUSED IN FREE RANGE SYSTEM

摘要: Poultry in free range systems and small farm flock results uncontrolled access of birds to all the sources environmental pollutants, since might accumulate elements not only from polluted soil, water, plants, geohelminths, as well various non-edible wastes substances containing i.e. heavy metal compounds. Therefore, housing laying hens system lead increased morbidity mortality (12) poultry products, such eggs, meat or giblets that be with toxic compounds (4,5,11). Particular intensification exposure (and other animals) occur industrialized regions, particular mine-metallurgical industry, where there are significant emissions imissions metals, including Cd Pb (9). From studies many authors it metals eggs content tissues organs galliform (13) waterfowl (3). Moreover, existing compounds, organic mineral, can reduce accumulation (1). The aim present work was assess influence humic-aluminosilicate preparation (HAP), feed for hens, on cadmium housed system.
