Crecimiento alométrico del Cavia porcellus (Cuy mejorado)

Abstract

The growing of Cavia porcellus (guinea pig improved),was evaluated by the weight and 22 body measurements, in male and female animals belonging to the same genetic line, from their birth to 6 months and in animals from different genetic lines from 6 to 12 months. With an ADEVA (variance analysis) of repeat measurements, the effect of time and sex were evaluate. Afterwards their different body measurements were correlated, using the Person correlations. In the animals group from 0 to 6 months the ear wide is the measure that stopped growing in first place, the finished their development the different geometrical measures among 53 and 123 days of life. Finally the weight, the length of back and the thorax perimeter were the zoometrical measurements that finished their development later to 151 days. In the group from 6 to12 months meaningful differences were not reported in ear width, length of leg 1, length of leg 2, foot length, jaw width, the rest of zoometrical measurements showed differences until the 259 days, being these minimum increases. Regarding to the correlations that is repeated is between the back length and the thorax perimeter, to the 30, 90 and 10 days of life.
