Which factor does NOT influence feed intake in livestock?

Body temperature is indeed a critical physiological parameter in livestock, but it does not directly influence feed intake in the same way that the other factors do. The primary influences on feed intake typically include aspects like animal size, since larger animals often require more feed to maintain their health and energy levels. Feed palatability plays a significant role as well; animals are more likely to consume feeds that are appetizing and palatable, thus directly affecting their intake levels. Likewise, health status greatly impacts feed consumption; healthy animals are usually more inclined to eat optimally compared to those that are sick or under stress. In contrast, while an animal’s body temperature can influence metabolic processes and overall health, it does not have a direct effect on the amount of feed an animal chooses to consume.
