Abstract:
survival rate of pure Fogera and their Holstein–Friesian crossbred calves. A retrospective type of study design
was used for conducting the study. The data used in the study was taken from the records of Chagni ranch and Andassa Livestock
Research Center between 2011 and 2017. The survival rates were estimated by using cox regression and Kaplan–Meier model of Stata
software. The mortality rate was 3% which was nearly the optimum level that many scholars agreed for successful rearing practices. The
result showed that breed, birth weight and season effects are significant risk factors of calves’ survival. Our findings suggest that better
management practices targeting at the first two months of age to and following weaning should be implemented to improve the survival
rates of calves.
