Rendimiento comparativo de componentes de la canal de conejos F1 de padre Nueva Zelanda Rojo o Gigante de Flandes ; Comparative yield of carcass components of F1 crossbred rabbits sired by a New Zealand Red or a Flemish Giant buck

Worldwide rabbit production is based on meat breeds such as the NewZealand Red variety (NZR). There are also ornamental breeds such asthe Flemish Giant (FG), with a large mature body. In Europe, meat x giantcrossbreds display excellent yields. This study compared the performanceof rabbits sired by a NZR (n=six males, six females) or an FG buck (n=ninemales, nine females) in Californian-crossbred does. At 91 to 93 d of age,the rabbits were weighed (live BW) and slaughtered. The carcass, viscera,skin, liver, kidneys, lungs, heart, legs (fore and hind), loin, and abdominalfat were weighed. Yields...

Worldwide rabbit production is based on meat breeds such as the NewZealand Red variety (NZR). There are also ornamental breeds such asthe Flemish Giant (FG), with a large mature body. In Europe, meat x giantcrossbreds display excellent yields. This study compared the performanceof rabbits sired by a NZR (n=six males, six females) or an FG buck (n=ninemales, nine females) in Californian-crossbred does. At 91 to 93 d of age,the rabbits were weighed (live BW) and slaughtered. The carcass, viscera,skin, liver, kidneys, lungs, heart, legs (fore and hind), loin, and abdominalfat were weighed. Yields from carcass, legs, and loin were determined.Data were analyzed by Proc GLIMMIX (SAS). There was no sire x gender(P>0.05) or gender (P>0.05) effects. The NZR-crossbreds presented lowerBW (P=0.0048) and lighter carcasses (P=0.0314), viscera (P=0.0172), skin(P=0.0004), kidneys (P=0.0004), lungs (P=0.0453), and hind legs (P=0.0007)than the FG-crossbreds. The observed differences, on average, were380.51, 158.76, 80.64, 104.58, 2.40, 1.70, and 0.79 g, respectively. The NZR crossbredshad 0.79% lower hind leg yields (P=0.0181). No other differenceswere observed between bucks (P>0.05). The NZR-crossbreds had smallercarcasses than their FG counterparts. Crossbreeding giant x meat rabbitsshould be considered to maximize Puerto Rico’s rabbit production. ; La cunicultura mundial se centra en razas cárnicas como la Nueva Zelandavariedad roja (NZR). También existen razas ornamentales como la Gigantede Flandes (GF), que alcanzan gran tamaño adulto. En Europa los cruces F1entre estas razas han mostrado un excelente rendimiento. El presente estudiocomparó el desempeño de conejos de padre NZR (n=seis machos y seishembras) o GF (n=nueve machos y nueve hembras) y madres Californianas cruzadas.A la edad de 91 a 93 d los conejos se pesaron (peso vivo; PV) yprocesaron. Se obtuvieron los pesos de la canal, vísceras, piel, hígado, riñones,pulmones, corazón, patas (delanteras y traseras), lomo y grasa abdominal. Secalcularon los ...
