Management in a livestock is described, with data obtained in 597 females, using both the traditional registration system and the Assessment Scale for Behaviour in Bullfighting Cattle (EBL-10). Results of both methods are compared. Relationships between bravery related behaviors and other variables such as the morphological type, the characteristic of humiliating and the two different origins present in this livestock are analyzed. The correlation between the final scores of the traditional system and the EBL-10 was significant (p <0.01). So was the reliability (p = 0.00). There is a significant increase in the final mean score of both methods with the increase in the humiliation variable. In both methods, the final mean score is higher in the Núñez origin. The three variables of greatest weight to explain the final EBL score (R2 = 0.91) are: transmission, offensiveness, and charging at the cape. If we consider the traditional final score as a dependent variable, the variables with the greatest weight are charging at the cape, charging at the mounted bullfighter's horse, transmission, nobility and fierceness (R2 = 0.85). The higher the phenotypic score, the higher the final mean score in both systems. There is a correlation between the score obtained in charging at the mounted bullfighter's horse and the final score obtained on charging at the cape (r = 0.53; p = 0.00). Both methods are useful for selection and management, although the EBL-10 provides greater discriminatory capacity. Morphology and humiliation seem keys to explain bravery. Modifications are proposed to improve the EBL-10 scale. [ABSTRACT FROM AUTHOR]

Para determinar valores referenciales séricos de ganado de lidia y describir el metabolismo de la vaca de lidia en el periparto, se seleccionaron dos explotaciones ubicadas en la cordillera central colombiana. La alimentación estaba basada en pastoreo directo con pasto Kikuyo (Pennisetum clandestinum) en praderas fertilizadas dos veces por año según análisis de suelos. El pasto presentaba un contenido de proteína cruda promedio de 13%, además los machos recibían una suplementación diaria de 2 kilos de cogollo de caña y entre 2 y 3 kilos de un concetrado comercial para bovinos, el cual tenía una proteína cruda de 14% y una energía metabolizable estimada en 2.8 Mcal/kilo de materia seca. La suplementación con cogollo de caña y concentrado se empezaba entre 8 y 9 meses antes de la temporada taurina colombiana en los meses de diciembre a marzo del año siguiente. Se escogieron al azar 39 animales (Grupo 1) categorizados según sexo-edad así: machos jóvenes y adultos, y hembras jóvenes y adultas, a cada animal se le extrajo sangre en un tubo sin anticoagulante. También se seleccionaron al azar 5 vacas (Grupo 2) cuatro semanas antes del parto, quincenalmente de cada vaca se tomó sangre sin anticoagulante terminando en la semana 10 postparto. En ambos grupos se analizó la glucosa, la fructosamina (Grupo 2), el colesterol, el β-hidroxibutirato (β-OHB), los triacilgliceroles, las proteνnas totales, la albϊmina, las globulinas y la urea. Los datos se analizaron mediante estadística descriptiva y ANOVA. Los promedios obtenidos fueron: glucosa 6.4±2.1 mmol/L, colesterol 2.9±0.5 mmol/L, β-OHB 0.2±0.1 mmol/L, triacilgliceroles 0.3±0.1 mmol/L, proteνnas totales 89±14 g/L, albϊmina 31±4 g/L, globulinas 55±13 g/L y urea 6.9±1.5 mmol/L. En el Grupo 1 se observaron diferencias sólo para la concentración de urea (pTo obtain blood chemistry values in bullfighting cattle and to describe the metabolism during peripartum period in bullfighting cows, two herds from Colombian Andes Mountains (4-6°LN y 75-76°LO) were selected. Cattle was feeding using grazing systems, and males older than two years were supplemented with concentrates. Thirty-nine animals were selected at random (Group 1) and grouped according age and gender (young and adult males, and young and adult females), blood serum samples were taken from each one. In addition, blood serum samples (10 mL) were taken every two weeks from five cows (Group 2), the first samples were taken four weeks before calving, and 10 weeks after calving the last ones. The concentration of glucose, fructosamine (Group 2), cholesterol, β-hydroxybutyrate, triacylglycerols, proteins, albumin, globulins, and urea was analyzed. Data were analyzed by means of descriptive statistic and ANOVA. The mean values in Group 1 for glucose, cholesterol, β-OHB, triacylglycerols, proteins, albumin, globulins, and urea were 6.4±2.1 mmol/L; 2.9±0.5 mmol/L; 0.2±0.1 mmol/L; 0.3±0.1 mmol/L; 89±14 g/L; 31±4 g/L; 55±13 g/L; and 6.9±1.5 mmol/L, respectively. There were differences for urea according to age and gender (p
