Evaluación de tres pastos de trópico húmedo en la alimentación de cuyes en la etapa crecimiento - engorde en un sistema de crianza piramidal

Abstract

In the Experimental Station “Pastaza” belonging to the ESPOCH, the supply of three pastures of the humid tropics was evaluated (maralfalfa, King grass and grass sunflower), to guinea pigs for fattening growth, with 70 repetitions per treatment, for a total of 210 experimental units, a completely randomized design was applied. The results established that the supply of different grasses of Humid Tropics of guinea pigs housed in pyramidal burrowing recorded best final weights (835,3g.), weight gains (560,97 g.), forage intake (4835,93 g.) balanced (2033,66 g.) and total consumption of food (6869,59 g.) Using maralfalfa grass (T1). When the guinea pigs fed whit sunflower grass, the most efficient feed conversion was recorded (5, 57), it means a smaller amount of food is required to transform it into meat. The higher weights to the channel (518,14 g.) and carcass yield (60,28%), as well as lower mortality by providing maralfalfa grass (T1), and the most important is the lowest cost per kilogram of weight gain was 1.90, since it has a high protein content. The economic analysis determined that is more profitable to raise guinea pigs in pyramidal burrowing supplying maralfalfa grass, as their usefulness (B/C 1.34), was 34 cents for every dollar invested, which is interesting especially because it solves the feeding problems in the humid tropics and also housing them in burrows, the space breeding is reduced, resources that raise profitability is saved.
