ABSTRACT
Kaur H, Devi
L., Seasonal count of gastrointestinal parasites in ruminant feces from
pastures in India, Onl J Vet Res., 18(4): 339-352, 2014. From April 2010 to May
2011 240 faecal samples for
parasite/eggs were collected from pastures in Patiala, Punjab, India. 102
samples were positive (42%). Helminth and protozoan eggs/oocysts recovered were
Haemonchus contortus,
Trichostrongylus, Strongyloides,
Oesophagostomum, Bunostomum,
Ostertagia, Coccidia,
Trichuris, Moniezia,
Paramphistomum and Fasciola
spp. The highest rate of infection (75%) was observed in September. The highest
percentage of monthly cases were in October with Haemonchus
80 and Trichostrongylus
60 followed by December Coccidia 66.6,
September Strongyloides 53.3, July Trichuris
36.3, August and January Oesophagostomum
33.3, July Moniezia
18.1, August and December Bunostomum 16.6, August Fasciola
and Paramphistomum 16.6, and in May with Ostertagia spp., at 12.5%. Highest total Fecal egg count (FEC/gm) of 3200 was recorded in October
with a 50% rate of infection. Percentage prevalence was 47 for Haemonchus contortus,
43 for Coccidia,
37 Strongyloides, 28 Trichostrongylus, 22 Oesophagostomum,
18 Trichuris, 8.8 Bunostomum, 5.8 Moniezia,
and Fasciola and Paramphistomum
spp. 2.9%. Coccidia
and other gastrointestinal nematodes, especially strongyles
were recorded as mixed infections i.e. 58.8%. Of 18,879 FEC, H. contortus
eggs were 36.7%, Strongyloides
21.8%, Trichostrongylus 20.1%, Oesophagostomum 13.2%, Bunostomum 7.2%,
and Ostertagia spp., 1%. The highest percentage of larvated eggs occurred in February (87.4%) and lowest in
April (19.2%). The highest FEC value occurred autumn i.e. 6983 and the lowest
in winter i.e. 2758.
