Analysis of factors affecting calf mortality in a herd of Surti buffaloes up to AFC.

The present study was undertaken on the “Analysis of factors affecting calf mortality in a herd of Surti buffaloes up to AFC”. The data on 455 calving records spread over a period of 25 years (19731997) used in this study were collected from “All India Co-ordinated Research Project” on buffaloes, Livestock Research Station, Vallabhnagar M.P.U.A.&.T-Udaipur (Raj.). The effect of period, season, parity and birth weight were worked out on mortality up to AFC. The results of the present studies indicate that the 19.834 + 1.888 percent of the total female calves born died before they reached before the milking herd. The least-square analysis of variance results indicate that the effect of period, season and birth weight of calves on mortality rate was found to be non-significant, however the effect of parity was found to be significant on mortality rate up to AFC.
