Cow-Calf Certification Practice Exam

By what percentage do energy requirements increase for cattle for each degree Fahrenheit below the lower critical temperature?

1. 0.5%

2. 1%

3. 1.5%

4. 2%

The correct answer is: 1%

Energy requirements for cattle increase by 1% for each degree Fahrenheit below the lower critical temperature. This critical temperature is the point at which the animal must exert additional energy to maintain its body temperature in cold conditions. Below this temperature, cattle enter a state of increased metabolic activity to generate more heat, thereby requiring higher energy intake to sustain vital functions and overall well-being. Understanding the impact of temperature on cattle's energy needs is crucial for effective management practices. If the temperature drops below the lower critical threshold, farmers and ranchers must adjust feeding strategies to ensure that their cattle have adequate nutrition to overcome the additional energy requirements brought on by colder weather. This adjustment means providing feed that has higher energy content or increasing the quantity of feed provided. By recognizing this 1% increase, producers can better plan their feeding programs during colder months, ensuring that cattle remain healthy, productive, and able to thrive despite environmental challenges.
