Abstract
Aim:
Gastrointestinal (GI) helminth parasitism is one of the major
constraints for profitable sheep production. Due to variations in
the prevalence of GI helminths from region to region, it becomes
important to map out accurately the parasitic fauna of a
particular region for development of suitable control measures.
Materials and Methods: An extensive study of GI helminths was
carried out in Budgam district of Kashmir Valley over a period of
1 year. A total of 1200 fresh ovine faecal samples from both sexes
of young ones and adults were collected in sterilized plastic bags
and examined by standard sedimentation and floatation techniques.
Positive faecal samples (15-20%) in each season were examined by
Stoll’s dilution method to determine the parasitic load. A total
of 120 faecal samples (30 samples in each season) positive for
strongyle eggs were subjected to coproculture using Petridish
method and the third stage larvae were harvested to find out
prevalence of different genera of strongyle worms.
Results: The overall prevalence of GI helminths was found to
be 77% with platyhelminths and nemathelminthes in 26.58 and 60.92%
animals, respectively. The overall prevalence of mixed GI
helminths was found to be 8.67%. Eggs of various helminths
encountered in the present study were those of Fasciola
spp. (3.58%), Dicrocoelium spp. (11.58%), paramphistomes
(4.83%), Moniezia spp. (7.92%), strongyle worms including
Nematodirus spp. (57.75%), Strongyloides spp.
(1.67%), and Trichuris spp. (1.5%). On coprocultural
examination Haemonchus spp. (55%) was found to be most
predominant strongyle worm followed by Trichostrongylus
spp. (17.5%), Ostertagia spp. (11.67%), Oesophagostomum
spp. (9.17%), and Chabertia spp. (6.67%). On seasonal
basis, highest prevalence of GI helminths was recorded in summer
(83.00%) followed by spring (78.67%), winter (76.33%), and autumn
(70.00%), the difference being statistically nonsignificant
(p>0.05). The prevalence of platyhelminths (Fasciola spp.,
Dicrocoelium spp. and Moniezia spp.) was found to be
non-significantly higher in winter, but paramphistomes showed the
highest prevalence in the summer season. Nemathelminth infection
was found highest in summer season and lowest during the winter
season. Eggs per gram (EPG) ranged from 0 to 1800, and an average
EPG count was found to be 454.35±27.85. EPG was found to be
highest in summer (684.00±69.83) and lowest in winter
(202.38±18.82). The overall prevalence of GI helminths was found
more in adult sheep (83.00%) compared to young ones (53.11%), the
difference being statistically significant (p<0.05). Similarly,
the prevalence of helminths was found to be higher in females
(78.32%) as compared to males (72.97%), the variation being
statistically non-significant (p>0.05).
Conclusion: Seasonal variation plays an important role in the
prevalence of GI helminths in addition to age and sex of the
animal.
