Crossbred calves, that’s good… but crossbred cows, that’s even better!

It is often and rightly mentioned that crossbreeding allows to produce better feeder calves that are more adequate for the market needs. However it cannot be said often enough that by acting on traits with low heritability, hybrid vigor – or heterosis – also generates very interesting results on breeding females : higher conception rates, less embryonic mortality, better disease resistance, increased longevity and dairy production.

In fact, maternal heterosis (crossbred cow) contributes almost twice as much as individual heterosis (crossbred calf) to increasing productivity in a herd (Table 1). Another appreciable benefit is that this gain comes with savings in production costs estimated at about 10 % and results from the fact that crossbred females produce more milk and a longer period of time than purebred cows (Tables 2 and 3).
