FURUSHO-GARCIA, Iraides Ferreira; PEREZ, Juan Ramón Olalquiaga; BONAGURIO, Sarita  and  SANTOS, Cristiane Leal dos. Alometric study of cuts and tissues of the carcass of purebred and crossbred Santa Inês lambs. R. Bras. Zootec. [online]. 2006, vol.35, n.4, pp.1416-1422. ISSN 1516-3598.

This study was conducted using 103 male and female lambs from the following genetic groups: purebred Santa Inês (SS) and crossbreds of Santa Inês x Texel (TS), Santa Inês x Ile de France (FS), and Santa Inês x Bergamacia (BS). Animals were slaughtered at one of the following body weights: 15, 25, 35 or 45 kg. After slaughter and cooling of the carcasses, the following cuts were made: neck, rib/flank, short ribs, loin, blade, and hindlimb. The alometric growth of each cut in relation to the empty body weight (EBW) was measured. The alometric growth of the neck was isogonic (b=1) for most genetic groups and accompanied EBW growth. However, for BS lambs the growth was heterogonic (b>1) or slow growth. TS and FS male lambs showed slower neck growth rate compared to the BS lambs. The rib/flank had slow growth for all groups but TS and FS lambs showed greater growth rate than the SS animals. For males, the blade development followed the EBW while females had a slower growth rate. The development of short ribs and loin was slow for all groups, except on FS female lambs, in which both short ribs and loin growth followed that of EBW; the alometric coefficients obtained for short ribs were lower on FS female lambs compared to those of the remaining genetic groups. The development of hindlimb accompanied the EBW for SS, TS and FS males and also for FS female lambs.
