Systèmes d'élevage

Systèmes de production

Livestock provide many goods and services to people, such as meat milk, eggs, hides, feathers, fibres, traction and manure.  As well as these they serve many social and financial roles in different societies. They may be raised primarily for subsistence or local sales, or may be raised to supply international markets with large quantities of produce. The scale, purpose and nature of the farming enterprise is known as the production system. Ruminant livestock, such as cattle, sheep and goats, tend to be dependent directly on the land. Their production systems therefore are largely determined by agro-ecology and land-use. Production systems for monogastric species such as pigs and chickens depend more on consumer demand and the level of capital investment.
