title: Abattoir survey of abamossal nematodes of sheep in Srinagar district (J & K).
abstract: Gastrointestinal trichostrongyles of small ruminants are one of the major causes of productivity loss. Epidemiological study was carried out to determine parasitic infection of sheep with abamossal nematodes at various abattoirs in Srinagar district of Kashmir Valley from August 2011 to July 2012. On the basis of necroscopy, out of representative 281 abamossa, 53.3 % were recorded to be infected with Haemonchus species and 41.2 % with Ostertagia spp. Thus, Haemonchus spp. were more prevalent than Ostertagia spp. in ovines (P > 0.05). Infection prevalence percentage of Haemonchus spp. was highest in late summer season and early rainy season (62.85 %) with peak value in the month of July (71.42 %) and lowest in winter (42.85 %) with minimum value in the month of February (40 %). Similar trend was seen with Ostertagia spp. having highest infection prevalence value during summer season (52.8 %) with peak values in the month of July (64.2 %) and lowest infection in winter (34.2 %) with minimum value in February (30 %). Moreover, non-local breeds were more prevalent than local ones (P = 0.05).
