“…Animals with a positive selection index had greater carcass traits than those from the other two groups, in accordance with the conclusions offered by Altarriba et al (2005). Weight at 210 d could therefore be an indicator of carcass quality.…”

“…Furthermore, the practical implications of having information about quality parameters related to bull sires has not been extensively studied in the international literature addressing carcass or meat quality (Maher et al, 2004;Altarriba et al, 2005). Intrabreed variability would be of major interest to breeders; to be competitive through an identifiable brand, they have to be able to offer the market a homogeneous product.…”

A total of 125 13-month-old, entire males of the Pirenaica breed were selected from among the progeny of nine different sires. They were used to study the intrabreed variability of 41 carcass and meat traits, including weights, lengths, diameters and perimeters, grading parameters, dissection of the sixth rib, pH, colour and meat texture variables, and sensory attributes. Pearson correlations were also calculated. Coefficients of variation ranged from 3.5% for dressing percentage to 47.0% for fat red index, and all of the values could be considered within the normal range for cattle. Carcass traits showed lower variability (11.7% on average) than meat variables (14.8% on average). Hence, to achieve a standardised product, it would be desirable to include in the breeding selection programme a variable that could be measured on the carcass and that can predict meat quality. Nevertheless, from the results of the present study, none of the variables studied fulfil this requirement, and further studies would be necessary to widen our knowledge on this subject.Additional key words: beef, linear measurements, meat instrumental quality, sensory quality. ResumenVariabilidad intra-racial y relaciones entre 41 características de canal y carne en la raza Pirenaica Se han utilizado 125 animales de raza Pirenaica, machos enteros de 13 meses de edad, descendientes de nueve toros, para medir la variabilidad intra-racial de 41 variables de canal y carne, incluyendo pesos, longitudes, diáme-tros y perímetros, escalas de clasificación, disección de la 6ª costilla, pH, variables de color y textura y atributos sensoriales. Se han calculado las correlaciones de Pearson. Los coeficientes de variación variaron del 3,53% para el rendimiento de la canal al 47,04% para el parámetro a* de la grasa, y estuvieron dentro del rango normal para el ganado vacuno. Las variables de canal mostraron menor variabilidad (11,75% de media) que las variables de carne (14,84% de media). Por lo tanto, para conseguir un producto más homogéneo, sería deseable incluir en el esquema de selección alguna variable que se pudiera medir en la canal y que fuera capaz de predecir la calidad de la carne. Sin embargo, ninguna de las variables estudiadas reúne estos requisitos, por lo que son necesarios más estudios en este sentido.Palabras clave adicionales: calidad instrumental de la carne, calidad sensorial, medidas lineales, vacuno.Abbreviations used: CV (coefficient of variation), EU (European Union), SED (standard error), WHC (water holding capacity).

“…The potential genetic response was detected using an independent linear model for each studied trait (l): (2) where y ijl is the phenotype of the jth individual belonging to lot i (L), b a is the regression coefficient with age (A ijl ), b(y ijl ,û 210 ) is the slope of the covariance that relates individual phenotype for the morphological trait with breeding value for W 210 (û 210 ) and e ijl is the residual.…”

Effect of growth selection on morphology in Pirenaica cattle

-Twelve variables were identified to define morphology in 109 calves sired by eight Pirenaica bulls widely used in artificial insemination. The effect of selection for weight at 210 days of age (W 210 ) was detected from the regression coefficient between the 12 variables and the selection index for W 210 used in the breeding plan. Unbiased estimates of the genetic correlated responses on the morphology were obtained without previously estimating the genetic correlation among traits. In Pirenaica cattle, selection for W 210 increased slaughter live weight, chest depth and corporal length. The expected changes on height (withers, back and rump), rump width and thoracic perimeter were lower but positive and statistically significant. indirect response / morphology / growth /weight to 210 days / cattle Résumé -Effet de la sélection pour la croissance sur la morphologie de la race Pirenaica. Sur 109 veaux, fils de 8 taureaux de race Pirenaica largement utilisés en insémination artificielle, on a obtenu 12 variables qui définissent la structure morphologique des animaux. Les effets de la sélection pour le poids à 210 jours d'âge (W 210 ) sur la morphologie ont été détectés à partir du coefficient de régression entre ces variables et l'indice de sélection pour le caractère W 210 utilisé dans le plan d'amélioration de la race. Ainsi nous avons obtenu des estimations non biaisées des réponses génétiques corrélées à la morphologie sans avoir besoin d'estimer la corrélation génétique entre caractères. On souligne que, dans la race Pirenaica, la sélection selon W 210 tend à produire des animaux avec un plus grand poids vif, avec une plus grande profondeur de la poitrine et longueur corporelle, tandis que les changements espérés sur les hauteurs (garrot, dos et croupe), largeur de la croupe et périmètre thoracique sont positifs et de plus petite importance, mais statistiquement significatifs.

“…However, the best fit was obtained when they were considered as an "early development" genetic group (Figure 1). Two factors can be related to this: first, the model was based on the equations of the AFRC (1993) originated from studies that were carried out 50 years ago (ARC, 1980), when the genetic characteristics of the animals were very different from nowadays; second, the weight at weaning that has been used traditionally as main criteria for selection programs (PEREIRA et al, 2006;ALTARRIBA et al, 2005;PHOCAS & LALOË, 2004) could have resulted in the selection of early maturing animals. The relation between observed and simulated average liveweight per group is shown in figure 2.…”
