H.  aSeasonal incidence of enzootic pneumonia and its effect on the growth of lambs.h[electronic resource]  c1976  aEnzootic pneumonia is one of the commonest diseases of sheep in New Zealand and may affect most young sheep in the late summer to autumn period during their first 2 years of life. The disease is usually subclinical or accompanied only by coughing. Outbreaks of very severe pneumonia in some flocks may result in deaths but such outbreaks are uncommon. Pneumonia accounted for 9% of deaths of adult sheep in a survey by Davis (1974) in Hawke's Bay and a slightly higher incidence from this cause was reported from a smaller King Country survey by Pyke (1974).  aAnimal pathology  aBody weight  aEpidemiology  aSheep diseases  aDoença  aOvino  aPneumonia  aEnzootica  aRespiratory diseases1 aO'HARA, P.
