| dc.description.abstract | The present investigation entitled " Studies on mortality pattern in buffalo calves" was undertaken to study the mortality pattern in Murrah and Surti buffalo calves and factors affecting mortality viz., breed, period of birth, season, sex, cause of mortality and age. The data generated at Dairy Unit, Department of Animal Husbandry and Dairy Science, Marathwada Agricultural University, Parbhani for the period from 1985 to 2004 were used for present investigation. The significance of various factors was tested by Chi-square test. It was observed that the overall highest mortality was observed in period P1 followed by P2, P3 and P4. Among the breeds Murrah buffalo calves suffered more in period P2 followed by P~, P3 and P4. Whereas in case of Surti buffalo calves highest mortality was observed in period P1 followed by P2, P3 and P4. There was significant differences among the losses in three different seasons. The mortality was more in winter born calves, followed by summer season, while it was less in rainy season. The mortality percentage of male and female showed significant differences. The overall mortality was highest in period P1• In period P ~, P2, P4 male mortality was more than female calves. In period P3 female calves has more mortality than male claves. There was correlation between effect of cause and sex. Effects of causes were significant in case of male buffalo calves. Total mortality of male sex was higher than female sex due to cause class-II followed by class I, IV, V and III. The mortality differences between both the sexes, causewise mortality and in different age groups was found to be Non-significant in both Murrah and Surti buffalo calves. The effect of causes and season was non significant. From the present study it can be concluded that the mortality pattern varied during different periods. High mortality was found in the age group of 0-30 days which is critical stage of life of the new born calves. The maximum mortality was recorded in winter as calving season of buffalo coincides with cold stress, hence newly born calves become susceptible to adversities of weather. Higher mortality was observed in males. Period P1 showed higher mortality than other three periods. The mortality percentage decreased in P2, P3 and P4 period due to proper sanitation, feeding, management practices followed on dairy unit. The main cause of mortality is pneumonia, pneumoer> teritis. Winter season and rainy seasons provided favourable conditions to grow disease causing micro-organisms. | en_US |
