Milk and beef produced from one dual puropse cow can reduce a population of cows and emission of green gasses by 30 %. Breeding to dual purpose is the future for the planet.
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.
