Which feeding practice is FALSE regarding mature rams compared to ram lambs?

Mature rams not needing more grain than ram lambs is accurate due to their differing nutritional requirements. While mature rams generally have more stable energy needs due to their size and established muscle mass, ram lambs are still growing and require a higher energy density in their diet to support their development. This growth phase often necessitates a higher intake of protein and energy-rich feeds, like grains, to facilitate muscle and bone development.

In contrast, mature rams primarily benefit from a balanced diet that might not heavily rely on grain. They require sufficient energy to maintain body condition and reproductive performance, but the nature of their diet typically includes a wider variety of forages and roughages, which contribute to a balanced nutritional profile.

The needs of ram lambs for a higher proportion of protein and energy-dense feed are indeed essential for their growth and development. As growing animals, they need additional protein to support muscle accretion and overall growth. Moreover, both mature rams and ram lambs require adequate roughage in their diets to maintain rumen health and function, which is critical for proper digestion and nutrient absorption across all ages of ruminants.
