Surveillance Of Disease Problems And Economic Losses In Commercial Broiler Farms In And Around Lahore - 1998

The main objective of present work was to investigate the prevalence of various diseases and economic losses, resulting due to various factors among the commercial broiler farms in and around Lahore. For this purpose, oniy those farms were included, for the purpose of collection of data which had a capacity from 5000 to 2000 birds. A questionnaire was designed to collect the data from each farm that related to morbidity rates, mortality rates, vaccination, susceptible age, managemental fault, economic losses and cost analysis for various diseases. This study project was divided into two portions. During one year retrospective study (October 1996 to September, 1997) data was collected from 28 broiler farms. They had a total capacity of 118,000 birds and overall diseases mortality rate was 9.09%. Important diseases observed in this study were IBD (2.5%), 1-IPS (2.09%), earJ' chick mortality (1.85%) followed by colibacillosis (0.6%). Respire tory disease complex (0.5%), Ascites (0.47%), Coccidiosis (0.4%), Aspergillosis (0.314%) and N.D. (0.05%). Economic losses due to these diseases were calculated to be about 4.7% ed on 10 farms randomly selected out of 28 farms. Influence of season on disease was observed by Jividing a calender year into winter season (October 1996 to March 1997) and summer season (April 1997 to September 1997). Comparison of winter and summer season revealed that the incidence of IBD, Ascites, Respiratory disease complex and early chick mortality were higher in winter than summer, while incidence of hydropericardium coccidiosis and colihacillosis were higher in summer than winter. In second phase of this project, a prospective study was arraiied from January, 1998 to March, 1998 in 22 farms. During this study, 21700 birds were examined and overall 9.91% mortality rate was recorded. Important diseases observed in this prospective study were IBD (2.9%), ECM (2.25%), Respiratory disease complex (1.08%) and lIPS (1.11%) followed by colibacillosis (0.67%), ascites (0.51%), foul typhoid (0.14%), coccidiosis (0.37%), aspergillosis (0.29%), fowl cholera (0.16%) and N.D. (0.13%) n descending order.
