Abstract

In the province of Cotopaxi Latacunga city, Guaytacama Parish near Guamani Narvaez assessed the productive behavior of guinea pigs according to the color from the birth to the start of reproductive life. It assessed 50 female guinea pigs ready for their first service of Peruvian refined and distributed in five treatments; each one with different repetitions being being the repetitions according to the number of animals by coral, which were distributed under a completely random design. The results indicate that the fur color of guinea pigs which are mothers for first time (from months old to mating) influenced on morphological parameters statically, but not in the production parameters. The white guinea pigs presented the graeted body length (26.60cm), while the red ones had greater length of face (5.89) and chest circumference (24.44cm). Unlike the guinea pings with a combinations of colors such as: (tan with white and red with while), presented in order the lowest body lengths ( 23.63and 23.50cm); face (4.28 and4.38cm) and chest circumference (22.50 and 22.13cm) respectively. The length of ears varied 2.75cm in guinea pigs of tan color to 3.21cm in the ehile female guinea pigs. Numerically the largest litter sezes at birth were the pigs of tan color (2.63pups/ bith) and the weaning stage in white female (2.40 pups/ litter) however fur color of guinea pigs did not influence the parameters considered statiscally from birth, exept the birth weight up to 90 days old small variations werw found numerically
