Seasonal variation in nematode parasite epidemiology and pathophysiology in cattle in three different agroclimatic zones of Chhattisgarh

Studies were conducted to understand nematode parasite epidemiology in local cattle of three different agroclimatic zones of Chhattisgarh by monitoring monthly faecal egg counts and genera of parasites present for a period of one year. Simultaneous bi-monthly estimation of haemoglobin and packed cell volumes were also conducted in the same animals. While increased egg counts were observed during July to September in all the agroclimatic zones of Chhattisgarh with dominance of haematophagous nematode Haemonchus spp. Significant decrease of haemoglobin and PCV values (P<0.05) could be observed in cattle of Chhattisgarh Plain (Durg), Northern Hill Region (Ambikapur) and Bastar Plateau (Jagdalpur) during months of June to December.
