Abstract

dies on patterns and trends of poultry diseases on commercial poultry farms >indh. h the data available at poultry disease diagnostic laboratories in various districts of :he data collected during survey was analysed to study the pattern and trends of poultry immonly occurring on commercial poultry farms of the province. These laboratories ing in Karachi, Hyderabad, Nawabshah, Mirpurkhas and Sanghar.* Thirteen major .eases i e. Salmonellosis, Chronic respiratory disease, Colisepticaemia, Fowl cholera, coryza. Fowl typhoid. Fowl pox. Infectious bursal disease, Lymphoid leukosis, Marek's ewcastle disease, Angara disease and Coccidiosis, were diagnosed during the study. In Salmonellosis was reported from 1328 farms. Chronic respiratory disease from 636 isepticaemia from 470 farms. Fowl cholera from SI farms. Infectious coryza from 463 vl typhoid from 4! farms.

Newcastle disease, Angara disease and Coccidiosis were reported from Karachi west being from Sanghar; but in case of Fowl pox. the highest number of outbreaks rted from Sanghar and the lowest from Mirpurkhas. Analysis of variance of data on of various diseases showed non-significant difference, amongst diseases and years in Mirpurkhas and Sanghar districts. Hyderabad and Nawabshah showed significant mongst diseases and non-significant variance amongst years. The morbidity rate per 15.7S8 percent for Salmonellosis, mortality rate per farm was S.274 percent and case e averaged 14.763 percent. The morbidity rate per farm was 23.995 percent for Chronic / disease, mortality rate per farm was 11.181 percent and case fatality rate averaged rcent. The morbidity rate per farm was 1 1.85 percent for Colisepticaemia, mortality rate .vas 5.25 percent and case fatality rate averaged 12.84 percent. The morbidity rate per 20.16 percent for Fowl cholera, mortality rate per farm was 9.14 percent and case ite averaged 23.473 percent. The morbidity rate per farm was 20.67 percent for coryza, mortality rate per farm was 10 percent and case fatality rate averaged 15.625 ’he morbidity rate per farm was 9.70 percent for Fowl typhoid, mortality rate per farm percent and case fatality rate averaged 25.08 percent. The morbidity rate per farm was cent for Fowl pox, mortality rate per farm was 10.97 percent and case fatality rate 22.225 percent. The morbidity rate per farm was 19.74 percent for Infectious bursal lortality rate per farm was 9.44 percent and case fatality rate averaged 21.53 percent. >idity rate per farm was 20.36 percent for Lymphoid leukosis, mortality rate per farm i percent and case fatality rate averaged 20.23 percent. The morbidity rate per farm was cent for Marek's disease, mortality rate per farm was 12.254 percent and case fatality ! cl 25 49 percent The morbidity rate per farm was 24.75 percent for Newcastle talitv rate per farm was also 24 75 percent and case fatality rate averaged 34.61 • morbidity rate per farm was I 1.54 percent for Angara disease, mortality rate per 17 percent and case fatality rate averaged 12.72 percent and the morbidity rate per ' 55 percent for Coccidiosis. mortality rate per farm was 14 IS percent and case iveraged 22 94 percent. The study of diseases showed similar pattern of occurrences tricts. The diseases like Salmonellosis, Chronic respiratory disease. Colisepticaemin, i. Infectious coryza. Fowl pox. Infectious bursal disease. Lymphoid leukosis, Marek's castle disease. Angara disease and Coccidiosis showed a rising trend on commercial is of Sindh, whereas Fowl typhoid showed a secular trend In this study, the social the poultry farmers in Sindh was also studied.
