Crecimientos diferenciales según fenotipos en el Borrego de Chiapas
MetadataShow full item record
Growth curves in the Chiapas sheep breed were assessed for males and females, comprising a wide age range of animals (3 to 156 months). Animals encompass 4 different phenotypes (white n=30, black n=77, tan n=28 and paint n=10). They were from different local communities in Chiapas (South Mexico). The
goodness of fit for four different models (logistic, von Bertalanffy, Michaelis-Menten and Gompertz) was assessed for 66 males and 79 females. The best model was the Michaelis-Menten one, which can be useful in order to study the growth kinetics for this breed. The paint phenotype is the most distinct variety and it has the highest final weight for the age range studied.

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; Perezgrovas Garza, Raúl (Universidad Nacional Mayor de San Marcos. Facultad de Medicina Veterinaria, 2016-10-22)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 ...
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 ...
