Carcass characteristics of lambs in grazing and confinement
Abstract
In sheep production fed high-forage diets, lower quality carcasses are generally observed compared to sheep fed high-concentrate diets. However, the use of concentrates raises the cost of production, so one of the alternatives is to include grazing periods during the fattening of lambs. Therefore, the objective of the study was to determine if the inclusion of grazing periods during the fattening of lambs affects the carcass characteristics. For which, 28 recently weaned lambs (Dorper × Pelibuey × Katahdin) were randomly assigned to one of two treatments: fattening in pen (EC) and fattening in grazing and pen (EPC). In EPC the first 51 days were given morning access to a ryegrass meadow. The characteristics of the carcass did not present a significant difference (p≤0.05) between treatments. Therefore, it is concluded that the inclusion of grazing periods during the fattening of lambs does not affect the characteristics of the carcass.
