Which statement about Bird's-foot trefoil is true?

Bird's-foot trefoil is well-regarded in agricultural practices mainly because it does not present the same bloat risks as some other forage legumes. Unlike certain legumes that contain high levels of soluble protein and can lead to bloat in ruminants, Bird's-foot trefoil has lower concentrations of these compounds. Instead, it contains tannins, but these have been shown to potentially reduce the risk of bloat by binding proteins in the rumen, making them less soluble and thus less likely to cause issues.

This unique characteristic makes Bird's-foot trefoil a suitable choice for grazing, as it provides a safe forage option for cattle without the common concerns associated with bloat. Understanding this aspect is crucial for livestock management and forage selection, especially when considering the diet of ruminants.

The other options suggest misunderstandings regarding the properties of Bird's-foot trefoil. For example, while high protein content can be a feature of some forage legumes, Bird's-foot trefoil is typically valued more for its digestibility and bloat safety rather than exceptionally high protein levels. Moreover, it is not primarily grown as a water source for cattle; rather, its primary uses include grazing, hay production, and as a cover crop due to its ability to
