Seasonal distribution of clinical morbidities among bovines in semi arid area

摘要

The influence of season oil the occurrence of bovine morbidities were studied for 3 years from 1994 to 1996 (Jan. to Dec.) in semi arid area. The alimentary tract disorbers. P.U.O. mastitis and other adder involvements, gynaecological disorders, surgical conditions, infectious diseases (H.S., FMD.), helminthiasis and other conditions (neurological, urinary, toxaemia/septicaemia, metabolic, dermatological affection) were common during the rainy season while respiratory affections were common duringthe winter months and occurrence of actinomycosis/ actinobacillosis were high in summer, indicating that hot and humid climate of rainy season is more stressful to the bovines in this arid region. The highest incidence of surgical conditions were observed (25.3 percent) followed by alimentary tract disorders (24.3 percent), mastitis and other adder affections (9.2 percent), P.U.O. (9.0 percent), female genital disorders (7.7 percent), respiratory tract diseases (5.3 percent), helminthiasis (5.0 percent), dermatological conditions (4.1 percent), metabolic disorder (1.9 percent), FMD (1.5 percent), H.S. (1.4 percent), urinary tract disorders (1.3 percent), haemoprotozoan infections (1,2 percent), neurological disorders(1.1 percent), toxaemia/septicaemia (0.9 percent) and actinobacillosis/actinomycosis (0.8 percent) in decreasing order indicating the pattern of disease occurrence in the semi arid area among cattle and buffaloes.
