Utilización de distintas relaciones energía/proteína en la alimentación de cuyes

Abstract

In the Minor Species Program of the Cattle and Livestock Faculty of the ESPOCH (Chimborazo Higher Eductional Polytechnic School) three relationships of Energy/Protein with 2600, 2800 and 3000 Kcal of EM and the same 16 % Protein level in the Gestation-Lactation and Growth-Fattening stages were evaluated. The results determined that the best treatment in the Gestation-Lactation stage was the one containing 2800 Kcal of EM presenting, higher weights at the end of mounting stage (1.21 Kg) postpartum and weaning (1.12 and 1.08 respectively) as well as a higher Prolificity was attained with the 2600 Kcal feed of EM (310 %). In the Growth-Fattening treatment the best treatment was 3000 Kcal of EM reaching the highest final weights (834 g) with weight increments of (504 g), better feeding convertion (5.59 ) higher weight and carcass yield (6.83 g, dry matter). The highest economic profetability in the Gestation-Lactation stage was attained using feed whit 2600 Kcal of EM whit 1.26 benefit/cost, where as in the Growth-Fattening stage it was atteined using feed 3000 Kcal of EM whit 1.28 benefit/cost. In the Gestation-Lactation stage it is recommended to use alfalfa plus feed Having 2600 Kcal of EM and 16 % Protein; in the Growth-Fattening stage, alfalfa plus a feed containing 3000 Kcal of EM and 16 % Protein.
