Which statement is TRUE regarding self-feeding ewes' rations?

Self-feeding rations for ewes are typically designed to ensure that they receive adequate nutrition while allowing them to regulate their own intake. A key component of these rations is roughage, which is essential for promoting healthy digestion and rumen function in sheep. The inclusion of a high percentage of roughage helps to prevent issues such as acidosis and supports the natural grazing behavior of ewes.

Incorporating a sufficient amount of roughage allows the ewes to maintain a healthy diet and provides the bulk necessary for proper rumen activity. This reflects a more natural feeding system, which is beneficial for their overall health and productivity.

Other statements do not align with the characteristics of self-feeding rations. While balance in nutrients is important, the focus on minimizing roughage or comparing their rations to cattle feed does not represent the ideal nutritional strategy for ewes.
