Influence of Aloe barbadensis (Miller 1768) Extract on White Blood Cells Counts a Immunological Parameters of Adult Heterobranchus Bidorsalis (Geoffroy Saint-Hilaire 1809)
Abstract: <div>Aloe barbadensis extract was incorporated in the feeds of adult Heterobranchus bidorsalis at concentrations of 0.0, 25.0, 50.0, 75.0, 100.0, and 125.0 mg/Kg of feeds in triplicates. Fresh gel was mixed with feeds and sundried. The fish werefed at 6% body weight divided into two rations per day. The fish were fed for 14 days before being analysed for hematological parameters such as total white blood cell count, lymphocyte, neutrophils counts, eosinophils counts, basophils counts as well as monocyte counts. The monocytes and eosinophils were significantly lower (p<0.05) in the treated fish while basophils were not encountered at all. The neutrophils and lymphocytes being the immune responsive leucocytes were increased in circulation due to Aloe barbadensis exposure. Aloe barbadensis extract</div><div>is therefore recommended as fish supplements at concentration of 50.0 to 75.0 mg/Kg of feeds for adult Heterobranchus</div>
