title: Dynamics of faecal egg count in natural infection of Haemonchus spp. in Indian goats.
abstract: OBJECTIVE
  Dynamics of faecal egg count (FEC) in Haemonchus spp. infected goats of two Indian goat breeds, Jamunapari and Sirohi, in natural conditions was studied and effects of genetic and non-genetic factors were determined.
  
  
  METHODS
  A total of 1399 faecal samples of goats of Jamunapari and Sirohi breeds, maintained at CIRG, Makhdoom, Mathura, India and naturally infected with Haemonchus spp., were processed and FEC was performed. Raw data generated on FEC were transformed by loge (FEC+100) and transformed data (least squares mean of FEC [LFEC]) were analyzed using a mixed model least squares analysis for fitting constant. Fixed effects such as breed, physiological status, season and year of sampling and breed × physiological states interaction were used.
  
  
  RESULTS
  The incidence of Haemomchus spp. infection in Jamunapari and Sirohi does was 63.01 and 47.06%, respectively. The mean LFEC of both Jamunapari and Sirohi (does) at different physiological stages, namely dry, early pregnant, late pregnant early lactating and late lactating stages were compared. Breed, season and year of sampling had a significant effect on FEC in Haemomchus spp. infection. Effect of breed × physiological interaction was also significant. The late pregnant does of both breeds had higher FEC when compared to does in other stages.
  
  
  CONCLUSIONS
  Breed difference in FEC was more pronounced at the time of post kidding (early lactation) when sharp change in FEC was observed.
