text 1982 PENYAKIT HEWAN en Vol.14(24) p.25-29. 1982 An analysis is made of some epidemiological aspects of an occurrence of bovine ephemeral fever (BEF) in and around Tuban, East Java, Indonesia between 1978 and 1982. The disease was shown to affect mostly adult male cattle and its geographical distribution is related to the prevailing seasonal windflow. Haemorrhagic septicaemi (HS) was shown to have been a significant complication factor, since a vaccination campaign against HS and individual treatments with broad spectrum antibiotics and vitamins reduced the mortality rate from 36.36 percents in 1978 to 2.35 percents. An attempt is made to quantify the economic loss, taking into account not only directy measureable factors such as market prices, but also the cost of lost animal labour.
