Relative importance of reproductive traits on lifetime milk production and profit Holstein-Friesian Hariana crossbreds



Relative importance of reproductive traits on lifetime milk production and profit Holstein-Friesian Hariana crossbreds



Progressive Agriculture 5(1/2): 101-103



This study reports on the use of a mathematical model (third degree polynomial regression analysis) in evaluating the relationship of reproductive traits (age at first calving and days open (%)) with lifetime milk yield and profit from Holstein-Friesian Hariana crossbreds maintained at six military dairy farms in Northern India.
