Abstract

The data collected from various authors in this study has allowed us to carry out a diagnosis of the interaction between protein and energy in the nutrition and feeding of guinea pigs. The aim of this study on the main sources of energy and protein in the nutriton and feed of guinea pigs was achieved. The data used in this study were obtanied using search engine, indexed scientific jounrnals, national and international repositories, thesis, and scientific articles based on a descriptive review of the interaction between protein and energy and its effect on the stages of gestation and lactation and the stages of growing and fattening. In the former, maternal behavior ( final weight of mating, postpartum weight, weight at weaning, weight gain, feed consumption, fertility, fecundity, profilicacy) and the offspring behavior ( litter size at birth, litter weight at birth, litter size at weaning, litter weight at weaning, mortality) are described, and in the latter, weight, weight gain, feed consumption, feed conversion, carcass weight, carcass yield, and mortality are described. Regarding the economic evaluation, the gestation and lactantion stage statistics was not affected by the use of different levels of protein and energy, that is to say, it does not improve the productive performance compared to the growing and fattening stage in which different analyzed variables showed better values with 3,00 Mcal and 16% of protein, and it is more profitable when using balanced diet with 2,60 Mcal and 16% of protein because there is a benefit cost ratio of $1,26. The nutritional requirements were not fully met because the aim of certain studies was to determine the effect of energy and protein with high and low levels in the physiological stages of guinea pig.
