The present study was conducted to investigate the epidemiology and economic losses due to HPS among commercial layer and broiler breeder flocks in Lahore district.
A pre-designed proforma was used to collect the data from each farmer related to morbidity, mortality, feed brand, vaccine source, vaccination schedule, susceptable age and economic losses. Among the 41 commercial layer farms and 11 brioler breeder farms, 16 and 9 were affected with hydropericardium syndrome. The average mortality rate was 8.7% and 10.7% in commercial layers and brioler breeders respectively.
Susceptibility of hydropericardium syndrome varied in different age groups in both commercial layer and brioler breeders from 3rd to 20th weeks of age and from 2nd to 14th weeks of age respectively. Vaccination against hydropericardiuni syndrome provided partial and/or no protection when inoculated either before infection or after the onset of clinical signs.
Due to hydropericardium syndrome the mortality rate was higher in summer as compared to winter. Mortality was 11.5% im summer months and 6.4% in winter months in commercial layer. In broiler breeder mortality was 16.83% in summer months and 6.36% in winter months.
Economic losses due to HPS was 0.35 million ruppees in 16 affected commercial layer farms maintaining 0.1 million birds and 2 million rupees in 9 affected broiler breeder farms maintaining 0.25 million birds between March 1991 to February 1992.
