Dual-purpose breeds are one of the solutions to the global challenges of feeding a growing population and of fighting environmental problems. Production of milk and beef by a dual-purpose breed such as Simmental can reduce the number of cows and greenhouse gas emissions by up to 30 %.
Balanced, homogenous herd without extremes is easy to manage and ready for automatic milking system. To maximize uniformity of the herd, no bulls with low reliability should be used.
Breeding to quality of milk and beef as for BB kappa casein or A2A2 beta casein will help farmers to market the product. BB kappa casein is not only more profitable for cheese producers, but it reduces a carbon footprint of one kilogram of cheese.
Only pure-bred breeding can guarantee sustainability. All the crossbreeding programs rely on pure-bred farmers. Breeding stock is additional income.
