Crossbreeding has been used with great success for many years in the pig and poultry industry. Research has shown that there is also a benefit of using crossbreeding in dairy production.
Several studies have found that the gross margin of a crossbred cow in a systematic crossbreeding programme is higher than for a purebred cow.
Due to heterosis effects crossbred cows are more robust and have a higher lifetime yield.
