| Summary: | <b>Aim:</b> The objective of this study was to find out the underlying
causes and factors which are associated with calf mortality.<p>
<b>Materials and Methods:</b> The 16 (1992-2007) year's data
of calf mortality in the Central Cattle Breeding and Dairy
Farm (CCBDF) were analyzed for season, age, sex, breed and
etiology.<p>
<b>Results:</b> Female calves (56.77%) died more than males
(43.23%). The mortality was significantly higher in exotic
and crossbred animals than in local/indigenous calves.
Mortality rate were 28.99%, 33.03% and 37.98% in rainy,
summer and winter season, respectively. The major causes of
death were respiratory tract disease (38.75%), tuberculosis
(20.02%) and alimentary tract infections (16.73%). The
other causes of death in calves occurred in the following
frequencies: Malnutrition (5.28%), debility (4.72%), hairball
(3.12%), babesiosis (2.56%), internal haemorrhage (2.56%),
tympanitis (2.24%), black quarter (2.24%) and foot and
mouth disease (1.76%). Age is the most important factor and
significantly associated with mortality.<p>
<b>Conclusion:</b> Calves of first month of life may have higher
mortality risk. |
