Brown Swiss robustness allows it to adapt to any climate: cold winters to warm climates. Several scientific studies have demonstrated this ability. By evacuating the heat more easily and maintaining physical condition, Brown Swiss is more resistant to heat than Holstein (AX et al, 2001; El Tarabany and al, 2016). This ability to withstand different temperatures explains the breed development around the world.
Brown Swiss cow is known for her excellent ability to adapt her production to the available feed supply. Since her metabolism is not extremely hyperthyroid, the Brown Swiss cow can adjust and optimize the synthesis and the mobilization of fat reserves according to the feed supply available. Its body condition is usually good in intensive herds requiring high milk production – over 10,000Kg – and in extensive herds where grazing is practiced with consequently lower production.
