6. EFFECT OF IVERMECTIN ON HAEMATOLOGICAL PARAMETERS OF HELMINTH INFESTED SHEEP by PATEL, M. J.1, BHATIYA, S. I.2, SHEKH, I. J.3,
Sheep are important species of livestock in India which contribute greatly to the areas where crop and dairy farming are not economical. In the present study, Helminth infected sheep were divided into three groups viz. Treatment group-I (n=30) animals were treated with Ivermectin injection at 0 day, group – II (n=10) animals were infested with various helminth and not treated with anthelmintic and kept as a positive control group and group-III (n=10) animals were negative for helminth kept as a negative control group. Blood samples were taken for haematological estimation at 0,7th and 14th day in group-I. However, in group-II and III were taken at 0 day. In the present investigation significant reduction in Hb, TEC and PCV, non-significant increase in TLC and eosinophil and no significant difference in neutrophil, lymphocyte and monocytes were observed, which indicated normocytic normochromic anaemia. These might be due to blood loss due to ingestion and excretion of ingested erythrocytes by the nematode.
