Feed rations formulated for self-feeding ewes primarily consist of which type of feed?

Self-feeding rations for ewes are designed to meet their nutritional requirements while ensuring they can regulate their own intake. A high percentage of roughage in these rations is beneficial because it promotes rumen health and function, which is crucial for sheep as they are ruminants. Roughage contributes to the necessary fiber in the diet, supporting rumination, and preventing digestive problems such as acidosis.

When ewes are allowed to self-feed, having a ration rich in roughage encourages a more balanced consumption of nutrients since they are less likely to overconsume energy-rich feeds, like concentrates, which could lead to metabolic issues. Furthermore, a roughage-based diet aids in maintaining overall gut health and provides a steady energy source without the rapid fluctuations that can occur with high-concentrate diets.

In contrast, rations that have a high percentage of concentrates may promote rapid weight gain but risk digestive disturbances if consumed in excess. Rations with equal parts or a high percentage of protein supplements might not adequately address the essential fiber requirements that ewes need, leading to potential health concerns. Hence, a high percentage of roughage is considered ideal for self-feeding ewes to ensure both health and optimal performance.
