Dressing Percentage, Measures of Carcass and Weight of Commercial Joint Santa Ines and Bergamacia Lambs Fed with Swine Wastes in Confinement

[摘要] - Twenty-one lambs of the Santa Ines and Bergamacia breeds were confined by a period of 75 days and fed diets containing 24% of swine wastes, in biju form (obtained by the scratching and sweeping of the floor of the growth stalls and termination) or dry sifted wastes - DSW (obtained through the sifting of the solid part of the material contained in the sheet of water and in the water of the wash of the stalls). The animals were slaughtered at 210 days of age, being determined the weight and measures of carcass, dressing percentage and commercial joints. There was no diet effect on the slaughter weight (SW), hot (HCW) and cold (CCW) carcass weights, hot (HCD) and cold (CCD) carcass dressing and percentage of cold loss (PCL). The lambs of Bergamácia breed showed larger SW, HCW and CCW. There was no differences among the diets or among the breeds for the parameters: total length, length of the leg, total length of the leg, internal length, perimeter of the croup and croup width. However, larger thorax depth and thickness of sub-coetaneous fat was verified in the Bergamacia lambs. There was no effect of the diets and breeds for the joints whole shoulder, rib, breast/diaper, loin, ham and previous and posterior arms.
