Vaccination coverage of contagious bovine pleuropneumonia in Adamawa State, Northeastern Nigeria

Abstract

Contagious bovine pleuropneumonia is an important, transboundary animal disease of high socio-economic impacts and vaccination has been recommended as one of the preferred option for its control. Twelve years (2006-2017) of data were retrieved from the Ministry of Livestock Production, Adamawa state. The relevant data collated included; estimated annual cattle population, number of cattle vaccinated against CBPP, number of CBPP outbreaks reported, number of mortality due to the disease, number of cattle slaughtered and examined for CBPP lesions and number of cattle with suspected CBPP lesions. The overall vaccination coverage of 4.80% was obtained with the highest vaccination coverage (20.57%) and the lowest vaccination coverage (1.03%) recorded in 2013 and 2015 respectively. A negative and insignificant correlation (r= -0.2346, p> 0.05) was obtained between vaccination coverage and prevalence, whereas correlation between prevalence and reported outbreak of CBPP was positive (r= 0.7381). A total of 76 outbreaks representing an average of 6.33 outbreaks per year and a mortality of 456 were recorded. The highest number of outbreaks (15) was recorded in 2017 whereas the least number of outbreaks (1) was recorded in 2007. The study has established low and irregular vaccination coverage which resulted in increased outbreaks of the disease in the study area. The need for Government to procure CBPP vaccines that is affordable as well as accessible to cattle owners at subsidized rates, increased and compulsory vaccination coverage of 80% for 5 consecutive years and enlightenment of cattle owners through public media on the dangers of the disease was recommended.
