Resumen
Descripción
Milk sales are the largest source of revenue on dairy farms. Reproduction is necessary to generate a new lactation. However, a pregnancy also dictates when the previous lactation must end so that the cow can retain sufficient condition into her new lactation. Pregnancy rate and estrus detection rate determine reproductive success. From an economics point of view, we talk about calving interval or days open so that a dollar value can be easily associated with the reproductive management program.
