Abstract
To study the relationship among soil, plants and animals regarding translocation of copper, the samples of soil, forage and animals were collected from livestock farm Rukh Ghulama (Distt. Bhakhar, Punjab) during winter and summer seasons. Results indicated that copper (Cu2+) status in soil was 0.24 mg/g below the critical level (0.5 mg/g) during summer season. While in forage Cu2+ concentrations were above the critical level (7.66 mg/g) and the animals fed with this forage had Cu2+ concentration in plasma (0.1 mg/g), milk (0.2 mg/g), urine (0 mg/g) and faeces (30 mg/g) and were almost within the critical limits. The essentiality of copper was suggested to prevent various diseases of animals including anemia and may produce numerous copper dependent metabolic enzymes.
