Interspecific pasturing, usually with larger livestock such as cattle or horses, make also help to deter predators, even if such species do not actively guard sheep. [26] In addition to animal guardians, contemporary sheep operations may use non–lethal predator deterrents such as motion–activated lights and noisy alarms.
The sheep are long-lived and can be productive for up to 15 years. [2] An ideal Churro, according to the breed standard, has a bare face, bare legs, and a mostly bare belly. [12] The sheep are hardy with light bones, narrow bodies, and long legs. They do not reach their full-grown size until well into their second year. [13]
Cows, sheep, and other ruminants digest their food by enteric fermentation, and their burps are the main source of methane emissions from land use, land-use change, and forestry. Together with methane and nitrous oxide from manure , this makes livestock the main source of greenhouse gas emissions from agriculture.

Flystrike in sheep is a myiasis condition in which domestic sheep are infected by one of several species of flies that are external parasites of sheep.
