Evaluación de los Tamaños de Camada al Nacimiento y su Influencia en los Parámetros Productivos en Cuyes.

Abstract

In the Academic Unit of Minor Species of the Faculty of Sciences of the School of Zoo technical Engineering of the ESPOCH located in the canton Riobamba, Province of Chimborazo, there was investigated the evaluation of the sizes of litter to the birth and its influence in the productive parameters in guinea pigs from the birth up to 105 days of age, being distributed under a Design Completely to the Hazard and evaluating different variables for 120 days of investigation. Determining the best productive responses relating to the weights in the litters of 3 offspring, with weaning weight of 0,610 kg, weight to the channel 0,515 kg and a cost/kg of body weight gain of 2,164 dollars. With regard to sex, the male animals presented numerically better productive behavior than females, overtaken in 60g weights in the end, 54 g in weight gain to the channel. The greater economic profitability found himself on the plumping guinea pigs of litters of 3 offspring, with a B/C of 1.15 compared to 1.04 that was obtained in litter of 4 pups, the effect of sex, males showed a superiority to females, since the B/C certain were 1.13 and 1.19 respectively. It is recommended that you replicate this work but with the use of food supplements to improve the productive parameters and achieve better economic returns.
