Prevalence of Gastrointestinal Helminth Infection in Garole Sheep of Sundarban Delta in West Bengal
Abstract:
Gastroenteritis caused by helminth is a major hindrance for optimum productivity in small ruminants. The present study was conducted to determine the prevalence of naturally occurring gastrointestinal helminths (GIH) and intensity of gastrointestinal nematode (GIN) infection in Garole sheep of Sundarban Delta of South 24 Parganas district in West Bengal. Sixty Garole in the age group of three months to one year were selected in two villages of South 24 Parganas district and coprologically screened by Standard technique at monthly interval for a period of one year (from Oct 2012 – September 2013). The prevalence of GIH infection was 82.22%. Highest prevalence (90.83%) as well as intensity of GIN infection (EPG = 521) was observed in monsoon and lowest prevalence (75.83%) and intensity (EPG = 388.75) was recorded in summer. Haemonchus contortus was recorded as the predominant GI nematode species with an overall prevalence of 63.91% and Paramphistome (15.28%) was reported to be the predominant trematode species infecting Garole sheep. The present study indicates that the naturally occurring GI parasites were prevalent in Garole sheep all round the year with the highest prevalence in monsoon. The results of the present study might be exploited for developing lucid and specific control measures against naturally occurring GIH in Garole sheep.
