Estudio del crecimiento relativo de los tejidos que componen las piezas de canales de corderos de raza segureña

Abstract

La relación entre e peso de los tejidos muscular, óseo y adiposo de siete piezas de canales de corderos de raza Segureña y el peso de la masa tisular de la media canal, arroja para el músculo de la pierna, espalda y costillar caudal, valores inferiores a la unidad (0,964, 0,911 y 0,805), por lo que se consideran de madurez precoz; el pecho es de madurez tardía ya que alcanza valores superiores a la unidad (1,348), el costillar craneal (0,930)madura de modo similar al conjunto. Para el hueso de la pierna y espalda, los valores de 0,919 y 0,934 indican un modelo de madurez precoz; tardía en el pecho (1,173). Por el contrario, es proporcional a la de la masa total de la canal, en el cuello, costillares y lomo, al alcanzar los valores de 1,146, 0,999, 0,922 y 1,147, respectivamente. En el tejido adiposo la porción intermuscular alcanza en la espalda, cuello, costillares y lomo los valores de 1,071, 1,029, 0,865, 1,029 y 1,037, que indican crecimientos similares al conjunto de la masa adiposa total, mientras que la pierna, con el valor de 0,828, presenta, un modelo de madurez precoz y el pecho, de madurez tardía (1,105). En lo que respecta a la grasa subcutánea los valores alométricos obtenidos fueron: 1,015 (pierna), 0,873 (espalda), 0,838 (cuello), 1,105 (pecho), 0,542 y 1,032 (costillar craneal y caudal) y 1,089 (lomo), valores que no difieren estadísticamente de la unidad lo que indica un ritmo de crecimiento proporcional a la masa adiposa total.

Thirty two half carcasses of male and female lambs of Segurena breed were joint into seven cuts and dissected. The relationship between the total mass of each joint and its composition in muscle, fat and bone shows, in the case of muscle, allometric coefficients (b) of 0.964 (leg), 0.805 (caudal ribs) and 0.911 (shoulder) indicating early maturing patte while the corresponding value for c al ribs and breast where 0.930 and 1.348. Regarding bones, leg and shoulder showed early development with b of 0.919 and 0.934; isometric growth was present in 1.146 (neck), 0.999 (craneal ribs), 0.922(caudal ribs) and 1.147 (loin). Intermuscular fat showed isometric growth in shoulder, neck, craneal and caudal ribs and in loin, their respective value being 1.071, 1.029, 0.865, 1.029 and 1.037. This value was of 0.828 in leg (early maturity) and 1.105 in chest (late maturity). In respect to subcutaneous fat, b showed isometric growth to total fat: 1.015 (leg), 0.873 (shoulder), 0.838 (neck), 1.105 (breast), 0.542 (craneal ribs), 1.032 (caudal ribs) and 1.089 (loin).
