“…The calves growth performances and carcass and meat quality obtained during the fattening period depend on factors such as genetic type, gender, initial and slaughter weight, feeding, environment and housing conditions and sanitary status (Daza, 1999). Although there are some experiments that have studied the productive traits and carcass and meat quality of calves of Avileña-Negra Ibérica breed (Sánchez Belda, 1983;Vassallo et al, 1989;Albertí et al, 1997;García & Cruz-Sagredo, 1999), to our knowledge there is not still enough information on the influence of the different variation factors on the performance traits, carcass characteristics and meat quality and, specially, on the fat quality of calves of this breed. Therefore, the objective of the present experiment was to study the effect of gender on growth performance, carcass quality, muscle and fat colour and fatty acid profile of backfat of calves of Avileña-Negra Ibérica breed.…”

The objective of this experiment was to study the effect of gender on growth performance and carcass and meat quality of calves of Avileña-Negra Ibérica breed. Sixteen calves, eight males and eight females, were used. The calves were fattened under intensive conditions, housed in confinement and fed with the same feed and cereal straw from 230.7 to 478.3 kg. The males grew more than the females (1.390 vs 0.932 kg day -1 respectively). Carcass weight, carcass length, leg length, leg perimeter, carcass and leg compactness, legs, fore-quarters and loins weights and forequarters percentage regarding carcass weight were higher (p < 0.05) in males than in females. The gender had not significant influence on CIE a*, b*, chroma and hue variables but CIE L* value was significantly (p < 0.05) lower in males than in females. The a* value decreased and b* and hue values increased with ageing time. The subcutaneous backfat from the females had significantly (p < 0.05) higher C14:0, C16:0, C16:1, C18:1 n-9, Σ MUFA and lower C10:0, C18:0, C18:2 n-6, C18:3 n-3, C20:0, C20:3 n-9, C20:4 n-6, C22:5 n-3, Σ n-6, Σ n-3 and Σ PUFA proportions than that from males. It is concluded that the gender has influence on growth performance, carcass traits and fatty acid composition of subcutaneous backfat; gender does not have effect on instrumental colour variables; and meat colour can reach acceptable values for consumers until four days after slaughter.Additional key words: ageing time; fat colour; muscle colour. ResumenEfecto del sexo sobre los resultados productivos, características de la canal y calidad de la carne de terneros de la raza Avileña-Negra IbéricaEl objetivo fue estudiar la influencia del sexo sobre los resultados productivos y calidad de la canal y de la carne de terneros de raza Avileña-Negra Ibérica. Dieciséis terneros, 8 machos y 8 hembras, fueron cebados en estabulación alimentados con el mismo pienso y paja de cereales suministrados desde los 230,7 hasta los 478,3 kg. Los machos crecieron más que las hembras (1,390 vs 0,932 kg día -1 respectivamente). El peso y longitud de la canal, la longitud y perímetro de la pierna, la compacidad de la canal y de la pierna y los pesos de la pierna, cuarto delantero y lomo y el porcentaje de cuarto delantero respecto al peso canal fueron más elevados en los machos. El sexo no tuvo influencia sobre las variables del color del músculo a*, b*, chroma y hue pero el valor de L* fue más bajo (p < 0,05) en los machos. El valor de a* decreció y los de b* y hue crecieron con el tiempo de maduración de la carne. La grasa dorsal subcutánea de las hembras tuvo proporciones más altas (p < 0.05) de C14:0,

“…One of the key issues for the future of ANI breed is the strength of the relationship between the farmers' prestige and the genetic level of the animals. For this specific population, Vassallo et al (1989) found out that the overall herd performance did not agree with the layer they occupy in the pyramid of the genetic improvement programme for the breed. Therefore, traditional prestige should have been related with other symbol of 'good farming' (Burton and Paragahaweva, 2011) and used for having a better insight into the drivers of gene flow within a domestic animal population.…”

“…Type A farmers might represent the traditional wealthy farmers that own farmland and also hold a traditional prestige. As a consequence their herds used to have a higher demand of breeding animals than herds of other farmer types (Vassallo et al, 1989). One of the key issues for the future of ANI breed is the strength of the relationship between the farmers' prestige and the genetic level of the animals.…”
