At a temperature of 14°C, heat stress begins to affect cows, leading to negative consequences for their well-being and health. Cows struggle to dissipate heat, resulting in decreased appetite and reduced milk production. Energy normally used for milk production is diverted to cool the body. Heat stress can also lead to decreased fertility and an increased risk of health problems, ultimately negatively impacting milk production.
- At 14°C, symptoms increase that negatively affect fertility.
- At 22°C, milk production decreases, depending on breed and barn conditions.
