Sažetak
Forecasts indicate that the world population will significantly increase till year 2050, placing up an enormous challenge to agriculture sector. Agriculture, especially livestock sector plays an important role in global environmental issues, such as climate change, land degradation, water pollution and biodiversity loss. Regarding the species, cattle are the main contributor to the sector’s GHG emissions (65%), but, on the other hand, cattle suffer significant losses due to induced climate change. Under heat stress conditions, lactating cows tend to decrease thteir performances resulting in a significant financial. The reduction of the GHG emission and minimizing the climate change could be achieved by short-term methods that imply increase of production per animal and feeding optimization, and long-term method that imply genetic evaluation and selection based on methane emission variation. In a case of introduction of genetic evaluation of dairy cattle for methane emission as well as selection of cows with lower methane emission intensity into the breeding programs it is necessary to define prediction models for body weight (BW), dry matter intake (DMI) and methane emission (CH4) based on parameters of dairy cattle population in each state. Finally, this will lead to environmentally (and economically) sustainable milk production. Since climate change is a global issue and livestock supply chains are increasingly internationally connected, effective mitigation actions could be achieved only by global approach. Therefore, the future of cattle breeding is in sustainable production system that provide effective production of high quality product with animals selected to high heat tolerance as well as to low GHG emission per kg of product
