Abstract

The objective of the experiment was to evaluate the qualitative characteristics of the lamb carcass, offspring of Santa Inês ewe, supplemented at different stages of pregnancy, finished in drylot. Forty eight Santa Ines ewe were distributed in four treatments using supplied food in different stages of pregnancy, in other words, to the third initial: pasture and cassava bagasse + supplement from the 1 the 50th day of pregnancy; to the third average: pasture and cassava bagasse + supplement from the 50th to the 100th day of pregnancy and to third end: pasture and cassava bagasse + supplement of the 100th day of pregnancy until the birth. The lambs after being weaned, were slaughtered at live weight of 30 kg. The live weight components of the lambs: blood, skin, digestive full and empty, reproducing organs with bladder, dull, liver, heart, respiratory organs with windpipe, kidneys with outlying renal fat, head and foot, weren´t influenced (P>0,05) by ewe supplementation in the different stages of pregnancy. Differences were not observed for yields of carcass cuts: leg, loin, shoulder, ribs, discovered ribs, bass and neck, in relation to the studied treatments.
