Abstract

The present study was conducted to investigate the prevalence of Haemonchus contortus and hematological changes in different age groups of H. contortus affected Nellore brown sheep. A total of 180 Nellore brown sheep flock maintained in an extensive system of grazing were selected randomly. Even though the sheep were dewormed regularly, an outbreak was noticed during May 2020 in Raptadu mandal of Anantapur district, Andhra Pradesh. Eight sheep were found dead in the flock prior to screening. During screening out of 180 sheep, 128 sheep were found normal and were kept as control group and 52 which exhibited clinical signs of anemia, poor growth, emaciation, diarrhea were selected. Blood samples were analyzed for the parameters like hemoglobin concentration (g/dl), Packed cell volume (%), Total erythrocyte count (TEC) and white blood cells (TBC), MCV (fl), MCH(pg), MCHC (g/dl) and compared with normal animals. The infection was confirmed to be due to H. contortus following the recovery of Haemonchus worms at post-mortem. The prevalence of H. contortus was recorded to be 40.9 percent in males (18 out of 44) and 25 percent in females (34 out of 136) with an overall prevalence of 28.89 percent (52 out of 180) in this present study.
