ABSTRACT

In order to achieve the objective, the data pertinent to lifetime traits on 762 Hariana cows, progeny of 23 sires maintained at Government Livestock Farm, Hisar were considered for the prediction of lifetime traits from early lactation traits. The prediction of phenotypic values for Number of lactation completed, Life time milk yield, Production life and Milk yield per day of productive life were obtained. The equation having the combination of first three lactation traits is recommended for the prediction of phenotypic value of lifetime traits in Hariana cows. Generally the peak yield of all lactations contributed maximum to R2 value for all lifetime traits. Therefore, it may be concluded that selection on the basis of peak yield would also improve the lifetime performance.
