Análisis de los Cambios Etarios según Sexo en el Borrego de Chiapas
MetadataShow full item record
A survey was conducted in order to study changes in body measurements in the Chiapas sheep breed. For this purpose 66 males and 79 females of various ages were measured: body weight, chest girth, knee perimeter, cannon perimeter, coronne perimeter, hock perimeter and ear length. The study reflects a regional change according to age, which are not isometrical. Body weight and chest girth are the most discriminative variables, which presented identical age regression trajectories for both sexes (F=1.006, p=0.317). Although body weight in adult male (>12 months, n=56) was greater than those of females (n=64) (U=1320, p=0.014), and no differences appeared for chest girth (U=1720, p=0.704), regression trajectories for both traits appeared similar.

Comparación de modelos no lineales para describir curvas de crecimiento según sexo en el borrego Chiapas Parés Casanova, Pere-Miquel; Caballero-Sala, Marta; Perezgrovas Garza, Raúl (Universidad Nacional Mayor de San Marcos. Facultad de Medicina Veterinaria, 2015-01-01)The aim of this study was to establish the growth curves in ovine Chiapas breed according to sex. Three models were used: logistic, von Bertalanffy and Gompertz. Body weight data were obtained from 66 males and 79 females ...
Parés Casanova, Pere-Miquel; Caballero-Sala, Marta; Pérezgrovas, R. (Medlife Scientific Press, 2014-11-24)Weight tapes and body weight estimation formulas are routinely used to determine the body weight of domestic mammals when a scale is not available. A sample of 145 animals (79 females and 66 males) of different ages (from ...
