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.
