Heat in farm animals can be detected by the following signs except
Answer Details
The correct option is "low blood temperature". When farm animals are exposed to high temperatures, their body temperature increases, and they try to dissipate this heat by various means such as sweating, panting, and seeking shade. The redness of the vulva in females is a sign of heat, which occurs due to increased blood flow to the reproductive system. Loss of appetite and increased water intake are also signs of heat stress in animals. However, low blood temperature is not a sign of heat stress, as the body temperature of an animal experiencing heat stress would be high, not low.
