Charcoal brooder is commonly used in Nigeria as a heat source during brooding of commercially raised chicks and its usage is associated with generation of smoke and poisonous gases. Its effect on vital parameters was assessed. One hundred day old cockerel chicks used in this experiment were separated into two groups A (control) and B (treated group). They were brooded separately under two different brooding methods with group A brooded with electric bulb and B with charcoal brooder. Intestinal contents of the chicks were collected at day 1, 14 and 28. Blood, liver, lung and intestinal content were also collected at day 14 and 28 to evaluate complete blood cell count, serum total protein, histological changes and intestinal bacterial load. Mean ± SEM values were calculated and compared for significant differences with independent T-test at p < 0.05. Significantly higher (p < 0.05) haematocrit value (35.40 ± 2.61%), haemoglobin concentration, total leucocyte count and lymphocyte count were recorded for group B at day 14. Significant increase in mean corpuscular volume (103.71 ± 5.29 fl) and lower heterophil count were recorded for group B as compared with control at day 28. Serum total protein decreased significantly in group B at day 14 as compared with the control. There was significant increase in heterotrophic bacterial count of group B as compared with control at day 14. Histologically, severe congestions of lungs, liver portal triad and central vein were observed at day 14 and 28 in group B. These results show that brooding with charcoal caused stress and hypoxia to the chicks and can contribute to early health problem in chicks. [ABSTRACT FROM AUTHOR] |
