- Abstract
An epidemiological study was conducted to evaluate the prevalence and intensity of gastrointestinal nematodes of sheep in slaughter house at Quetta, Balochistan, from April 2011 to March 2012. A total of 960 gastrointestinal tract samples (80 per month) of sheep were examined during the study period. The overall prevalence of gastrointestinal nematode was 49.47% with the intensity of 516.63 in sheep. The higher monthly prevalence of gastrointestinal nematodes was observed during April (65%) followed by November (62.5%) and October (57.5%). Statistically there was significant differences (P<0.05) amongst months. The genus-wise intensity among gastrointestinal nematodes was presented higher by Haemonchus (213.05), followed by Trichostrongylus (137.05), Trichuris (90.1), Ostertagia (44.21) and Nematodirus (32.21). Breed-wise prevalence of gastrointestinal nematodes was higher in Balochi (50.20%) than the Harnai breed (48.75%). While, sex-wise prevalence of gastrointestinal nematodes was higher in female (56.87%) as compared to the male (42.08%). Age-wise prevalence of gastrointestinal nematodes in sheep was higher in the age group of < 1 year (60.83%) followed >2 years (43.33%) and 1-2 years (41.25%). Statistically there was no significant difference P > 0.05 between breeds, sex and age groups. Five genera of gastrointestinal nematode parasites were recovered during study period. Among these Haemonchus was the highest (71.36%) prevalent followed by Trichostrongylus (58.49%), Trichuris (28.84%), Ostertagia (17.26%) and Nematodirus (9.47%).
