    ABSTRACT: Se estudiaron las características de la canal de cabritos lactantes de las razas Criollo Cordobés y Anglo Nubiana, utilizando 20 machos de cada raza. Los animales se sacrificaron a dos edades: 60±2 días (grupo I) y 90±3 días (grupo II). Los rendimientos canal y el grado de engrasamiento fueron superiores en Anglo Nubiana. La raza y la edad al sacrificio tuvieron un efecto significativo en la valoración subjetiva, en las medidas e índices de la canal y en el quinto cuarto.

    ABSTRACT: Thirty males and thirty females suckling Criollo Cordobes kid goats of approximately 60 to 90 days old were used in this study. Kids were slaughtered at <9.5 kg, >9.5<11 kg and >11 kg of empty body weight. The carcasses showed a medium conformation index. The meat and fat colour, and internal subcutaneous fatness were mainly scored as either pink, cream, slight and low-medium, respectively. The shoulder comprised 66-67% muscle, 24-27% bone and 4-6% fat. The slaughter weight had significant effects on the following characteristics: dressing yield, carcass measures and indices, subcutaneous fatness, meat colour, and muscle/fat ratio. The effect of gender was smaller: the female kids presented the highest fatness values for all parameters studied. Also, these animals displayed the lowest percentage of joints of extra class. The meat of female kids contained significantly less muscle and bone and a higher proportion of fat than that of male kids. The allometric analysis displays an early growth in the carcass measures and indices, fifth quarter, joints and bone proportion of shoulder. Internal and dissectible fats show a late growth. Principal component (PC) analysis was performed to study the relationship between carcass quality variables. The six first PC's explained about 85% of the total variability. The weight and yield of the carcasses were more effective to define the first PC. The projection of the carcass quality data in the first two PC's allowed distinguishing between carcass weight and carcass conformation groups, but not between gender and fatness.

    ABSTRACT: Physicochemical and organoleptic characteristics of meat (longissimus muscle) from Criollo Cordobes (CC) and Anglonubian (AN) suckling kids were analysed to determine the effects of genotype and slaughter weight. Forty suckling entire male kids, 20 CC and 20 AN were assigned to two age/slaughter weight groups (I: 60 + 2 days old and ⩽11 kg, and II: 90 + 2 days old and >11 kg). Colour, shear force and cholesterol levels of meat were affected by breed. Tenderness decreased and cholesterol increased with age/slaughter weight. Fatty acid profiles were affected primarily by genotype. The sensory attributes were perceived as medium-high intensity, and meat from CC and AN goat kids was valued as tender. However, initial tenderness and connective tissue varied with genotype. The main effect due to the increase in age/slaughter weight was a decrease in tenderness (initial and overall), as observed for instrumental shear force.
