The growth of sheep has an important relationship with the temperature and humidity of the sheep house. The temperature has a great influence on the sheep's body. Studies have shown that the most suitable temperature for sheep growth is between 5 and 21 degrees. Sheep body fat reduces feed utilization and reduces sheep body weight, and if it is too low, it is easy to cause diseases such as colds and fever in sheep.

Sheep have incredible survivability in extremely harsh conditions, and can rely on poor straw and leaves to survive. Compared with sheep, goats are more adaptable to harsh environments. In addition to eating various weeds, they can also eat a certain amount of grass roots and bark.Rocky Mountain Bighorn is another name for bighorn sheep.

Rocky Mountain bighorn sheep are close relatives of goats, with rough hoofs for grip and balance, and a keen eye to help them navigate rough terrain and rocks with ease. Bighorn sheep are pack animals. Agile, sharp-sighted, and good at climbing steep rocks so that they can avoid the pursuit of predators. Bighorn sheep have relatively long legs. When feeding or resting, there is often an adult sheep watching at a high place, which can detect abnormalities in a long distance in time, and send a signal to the group when danger comes.

Bighorn sheep prefer to live in naturally occurring rocky, dry mountains. It inhabits a variety of open, dry deserts, savannahs, and rocky mountains, including alpine meadows, grassy slopes, deserts, sparsely vegetated foothills, rocks near cliffs, alluvial plains where deserts and mountains meet, and mountain valleys. They can run and jump on cliffs and come and go freely. Mountains are an excellent habitat for rocky goats. The cliffs are full of vegetation, and the rocky goat is one of the few animals that can climb that high to feed.

Bighorn sheep feed on grasses and shrubs. When heavy snow covers the mountains, only a few places can see green grass. Bighorn sheep struggle every day to find this snow-free patch of grass for food. To save energy, they dig for food only when the wind can't clear the snow on the grass. Can go a few days without water, eat snow in winter without water. Bighorn sheep have keen senses of sight, hearing and smell, and are alert and alert. Often in small groups, the number of each group is small, only a few to more than ten are more common.The Rocky Mountain Bighorn Sheep is the provincial animal of Alberta, Canada, and the state animal of Colorado, appearing on the logo of the Colorado Department of Wildlife.
