pasteurellosis in rabbits with special reference to microclimatic conditions

The aim of this work was to study pasteurelosis in rabbits with specialreference to rnicroclimatic conditions. Two big rabbit farms at Sharkia were studiedover a period of one year from January 1994 to December 1994. The study. included and revealed :I Microclimatic Conditions :1. Temperature:The highest temperature recorded was 39 CO recorded in April and thelowest 11 C” recorded in January.2. Relative Humidity:The highest was 96 % recorded in January. While the lowest was 50 %recorded in July.3. Ammonia Concentrations:The highest was 52. P.P.m recorded in September, while the lowest was21p.p.m. recorded in May.11 Morbidity and Crude Mortality :The highest morbidity rate was 23.6 % recorded in November, while thelowest was 10.4 % recorded in June.The highest crude mortality in litter was 30% recorded in December, whilethe lowest was 12.2 % recorded in July. In preweaners the highest crude mortalitywas 21.4 % recorded in January, while the lowest was 14.5 % recorded in June. Inadult the highest crude mortality was 5.6 % recorded in December, while thelowest was 2.2 % recorded in June.
