Longitudinal study of calf morbidity and mortality on smallholder farms in southern Ethiopia.

ABSTRACT: Calf morbidity and mortality are serious constraints in the success of dairy calf production. Thus, the current study was carried out with the objective to estimate the incidence of calf morbidity and mortality and associated risk factors in milk-shed districts of Gamo Zone, Southern Ethiopia.
