Sero-Prevalence and Risk factors of Chicken Anaemia Virus in Khartoum State - Sudan

Abstract

This study aimed to determine the prevalence and risk factor and to assess the occurrence of chicken anaemia virus (CAV) in Khartoum state. Sudan. A total of 450 serum samples were collected randomly from commercial chickens’ farms in different areas in Khartoum State (210 layers and 240 broilers). The samples were tested by indirect ELISA commercial kit. Out of 210 serum samples 201 from layers, were found positive for chicken anaemia virus (95.7%). In broiler flocks, 129 were found positive and the prevalence rate was 53.8%. The estimated overall sero-prevalence rate of CAV was found to be 73.3%. In the univariate analysis using the Chi square test for risk factors , governorate and locality, (type of production, poultry population, husbandry system, body condition ,source of poultry, floor type, vaccination, breeds and age ), (p-value ≤ 0.05), were found to be significant risk factors. The risk factors found to be significantly associated with increased odds of being ELISA positive in the multivariate analysis were governorate, type of production, poultry population, husbandry system, source of poultry and vaccination (p-value ≤ 0.05)were significant risk factors. While the factors found not significantly associated with increased odds of being ELISA positive were , ages, floor type and poultry population(p-value > 0.05). Investigation results suggest that CAVD has wide spread in Khartoum State. In conclusion, the disease is highly prevalent in Khartoum State, Sudan. Urgent need therefore exists to initiate a realistic network for surveillance, control and eradication of this important viral poultry disease in the Sudan.
