Abstract
Aim: The aim of the present
study was to determine the morbidity and mortality rates of Bovine
population present in Himachal Pradesh, India. In addition, the
effect of age, sex, environmental conditions, management practices
and other factors on the morbidity and mortality rate was also
analyzed using suitable statistical techniques.
Materials and Methods: Himachal Pradesh has been divided
into four agro-climatic zones. Taking each agro-climatic zone as
stratum, five veterinary hospitals from zone 1, two veterinary
hospitals each from zone 2 and zone 3 and three veterinary
hospitals from zone 4, were selected randomly. Three villages were
selected from the villages covered by each veterinary hospital by
simple random sampling without replacement scheme. A total of 15
livestock owners were selected from each selected village and thus
a total 540 livestock owners constitute the ultimate sample from
thirty six villages and twelve veterinary hospitals for the study.
The sampling scheme followed in the present study is Stratified
three-stage random sampling. Age, sex, season and cause wise
morbidity and mortality data were collected from all selected
bovine owners in the state for period of one year (January 2011 to
December 2011).
Results: The Overall analysis of morbidity rate in bovine
was 31.22%. Among the three age groups, adults' bovine showed
highest morbidity rate 35.73%, followed by calves 26.98% and young
stocks 23.17%. Among the three age groups, calves had highest
morbidity rate 16.09% due to poor management problems followed by
adults 12.15% cases of reproductive problems. The overall
mortality rate in bovine was found 9.14%. The overall analysis of
mortality in bovine with respect to age revealed significance
(p<0.01) difference between age and sex. Amongst the three age
groups, calves showed highest mortality 21.53% followed by young
stocks 9.35% and adults 4.73%. Among the three age groups, calves
had highest mortality (16.09%) due to poor management problems
followed by 2.48% cases of digestive diseases.
Conclusion: Overall bovine morbidity and mortality rate
were 31.22% and 9.14%. Major causes of morbidity were reproductive
diseases followed by specific diseases and mortality were poor
management problems followed by digestive diseases and specific
diseases.
