What is the most likely consequence of intense grazing on tall fescue pastures?

Intense grazing on tall fescue pastures can lead to significant negative consequences due to the physiological stress it places on both the forage and the grazing animals. One of the primary problems associated with overgrazing is the degradation of forage quality and the ability of the grasses to recover. Tall fescue, particularly when grazed too heavily, can lead to a reduction in valuable nutritional components and energy content, which can adversely affect the health of livestock.

When livestock are subjected to continuous intense grazing, they may not receive adequate nutrition, which can result in a poor body condition. This inadequate nutrition can manifest as weight loss, lethargy, and in some cases, fever, particularly if the animals are also exposed to fescue toxicosis, a condition caused by toxic alkaloids produced by certain fungi that can thrive in tall fescue, especially when the grass is stressed.

The other choices relate to positive outcomes that may occur with appropriate management. Better weight gains and higher quality forage can be achieved with proper grazing techniques that promote pasture health and allow for recovery periods. Increased hoof health also typically results from rotational grazing practices that keep animals moving to fresh pastures. However, intense grazing undermines these benefits and leads instead to the
