dc.description.abstractLa raza bovina MarismeƱa es muy caracterĆ­stica por estar localizada casi exclusivamente en el Entorno Natural de DoƱana (Parque Natural y Nacional). Con objeto de caracterizar el crecimiento, se tomaron pesos individualizados de los animales durante los Ćŗltimos cinco aƱos. En total se recogieron 1771 pesos, 470 de machos y 1301 de hembras. Los datos fueron utilizados para hallar la curva de crecimiento con los modelos de Brody, Von Bertalanffy, LogĆ­stico y Gompertz. Para la elecciĆ³n del mejor modelo se usaron dos parĆ”metros: el coeficiente determinativo (R2) y el cuadrado medio del error. El modelo mĆ”s apropiado fue el de Brody tanto para machos como para hembras, con un R2 de 0,92 y 0,86, respectivamente. El modelo resultante fue: machos, peso = 633,95 * (1 - 9515 * exp (-0,0009 * edad)); hembras, peso = 387.60 * (1 - 0,9429 * exp (-0,0016 * edad)). La raza MarismeƱa mostrĆ³ un lento crecimiento y un claro dimorfismo sexual, muy notable a partir de los 2 aƱos de edad.pt_PT
dc.description.abstractAbstract The MarismeƱa cattle breed is very singular in Southern Spain as it is located almost exclusively in the DoƱana Natural Area (Natural and National Park). In order to characterize their growth, the weights data of animals of different ages were collected from the last five years. Data totaled 1771 weights, collected from males (n=470) and females (n=1301). The data was fitted to growth models: Brody, Von Bertalanffy, Logistic, and Gompertz. To choose the best model to explain the growth, two parameters were used: the determinative coefficient (R2) and mean square error. The most appropriate was the Brody Model for male and female, with an R2 of 0,99 and 0,862, respectively. The resulting models were defined as: males, weight = 633.95 * (1 - 9515 * exp (-0,0009 * age); females, weight = 387.60 * (1 - 0,9429 * exp (-0,0016 * age). The MarismeƱa breed cattle showed a slow growth and a clear sexual dimorphism, very noticeable after the age of 2 years.pt_PT
