Posición de la cabeza (PC) y de las manos (PM), recorrido del toro (RE) y modo de finalizar (FI) la embestida define el desempeño del toro, y pueden ser considerados como criterios de selección. El objetivo fue estimar heredabilidades (h2) y correlaciones genéticas (rg) para PC, PM, FI y RE; y construir dos índices de selección: IS1 con valores relativos de un análisis factorial, IS2 con valores relativos a partir de la desviación estándar de cada rasgo. Se calculó la respuesta a la selección (RS) y exactitud (EX) de cada IS. El número de observaciones (valor promedio ± desviación estándar) para PC, PM, RE y FI fue 984 (5.46 ± 1.4), 978 (2.93 ± 1.1), 981 (3.15 ± 0.7) y 785 (2.88 ± 1.1), respectivamente; con escalas de uno a siete para PC, y de uno a cinco para el resto de las variables. Para h2 y rg se realizó un análisis multivariado con el software MTDFREML. La h2 fue de 0.20 ± 0.06, 0.15 ± 0.05, 0.13 ± 0.03 y 0.17 ± 0.05 para PC, RE, PM y FI, respectivamente; todas las rg fueron positivas, de 0.57 a 0.94, con valor promedio de 0.753. IS1 = 0.068*PC + 0.048*RE - 0.012*PM + 0.088*FI; con EX de 0.46 y RS de 0.325. IS2 = 0.231*PC + 0.249*RE - 0.038*PM + 0.298*FI; con EX de 0.45 y RS de 1.15.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: In Lidia cattle breed, the selection is based on the performance of the bull during the fighting. Head position (HP) and hands (PH), course of the bull (CB) and finish of the onslaught (FO), define the performance of the bull, and can be implemented as selection criteria. The objective was to estimate heritability (h2) and genetic correlation (rg) for HP, PH, CB and FO; and building two selection indexes: IS1 with relative values of factorial analysis, IS2 by relative values from the standard deviation of each trait. The response to selection (RS) and accuracy (AC) were calculated. The number of observations (average ± standard deviation) value for HP, PH, CB and FO were 984 (5.46 ± 1.4), 978 (2.93 ± 1.1), 981 (3.15 ± 0.7) and 785 (2.88 ± 1.1), respectively; with scales of one to seven for HP, and one to five for the rest of the variables. For h2 and rg a multivariate analysis was performed with MTDFREML software. The h2 was of 0.20 ± 0.06, 0.15 ± 0.05, 0.13 ± 0.03 y 0.17 ± 0.05 for HP, CB, PH y FO, respectively. All rg were positive, from 0.57 to 0.94, with average value of 0.753. IS1 = 0.068*HP + 0.048*CB - 0.012*PH + 0.088*FO; with AC of 0.46 and RS of 0.325. IS2 = 0.231*HP + 0.249*CB - 0.038*PH + 0.298*FO; with AC of 0.45 and RS of 1.15.]]></p></abstract>
