Resumen : It is ussually assumed that weight does not depend on the amount of food eaten by animal but, rather, on its genetic makeuup, which expresses itself over time. Under equal manager and feeding conditions, guinea pigs of the Peru and Inti strains reached marketing weight (750 g) between the ninth and the tenth week of age, while the same weight in the Andina strain amd the control group (common guinea pigs) was not reached until the 12th week. It was also found that breeding weight (540 g) in the Peru and Inti strains is reached one to two weeks earlier than in the Andina strain or the control group. The greatest weekly weight gains were obtained between the first and the third weeks of age, while the lowest increments occurred between the 17th and 19th weeks, except for the Peru strain, which had its lowest weight gain in the 13th week. The total litter weight was superior ( by more than 35%) in the inti an andina strains as compared to the peru and control groups, due to the Peru and control groups, do the fact than the former strains produce litters averaging 3.2 and 3.0 guinea pigs while the letter ones producer only 2.0 and 2.2, respectively time is the most important parameter for the poor farmer, he usually suffers from strong price cubacks, prefers to make small gains now rather than for hither gains in to the future. Nevertheless, the producer is willing to keep his animal for a longer period if net return is too low or, conversely, to sell therm if the net return is high. The producer usually does not realize when the opportunity cost of his capital is equal to zero.
