Cobalt increases the red cell mass in both man and animals by increasing the production of erythropoietin. Since meat-type chickens can develop pulmonary hypertension from increased erythropoiesis and polycythaemia, two trials were conducted to investigate the role of cobalt on broiler chicken erythropoiesis and pulmonary hypertension. The results showed that feeding cobaltous chloride at 500 parts/10(6) to meat-type chickens from 1-day-old for 42 days significantly increased haemoglobin… CONTINUE READING
