Horn growth is an important part of raising Pure mouflon. The only sure-fire way to get good growth is nutrition and genetics. Horn growth begins from a bony core. Around the core of bone, keratin-a material that resembles human fingernails and that is found in hooves and constitutes the actual horn-begins to envelop the bone. Over several years, the keratin soon completely covers and extends beyond the bony core. The bony core ensures growth, as the years progress, the core develops a multitude of honeycombed chambers that provide avenues for blood vessels and nerves. In turn, the vessels and nerves support, maintain, and provide the physiological mechanism for additional horn growth.
Unlike the antlers of elk, moose, and deer, which are shed annually, the horns of mouflon sheep are retained throughout their lives. Not surprisingly, much of a ram's stature within the herd is determined by his genetic capacity to produce large horns.
Horn growth is dependent on a variety of factors, including diet. Throughout life, horn development depends on the minerals and protein received along with genetics.
