Comportamiento productivo de pollos capones comerciales con dietas isoproteícas y diferentes niveles de nergía en base a quínua

Abstract

At The Poultry Research Academic Unit (PROCAP Project), of ESPOCH, four types of diets based on quinua at different energetic density (2600, 2800, 3000, and 3200 Kcal of ME/kg and MS) were tested in the capon commercial chicken “pio-pio” in order to determine the capon commercial chicken productive behavior from isoprotein diets based on quinua at the different levels of energetic density, every test consisted of a 25 repetitions treatment which were give in regarding a randomdesing. The study results reveal that the capon commercial chicken treated with a diet based on quinua at a 3206 Kcal of EM/kg energy density reached the best final weight accounting for 3661,96 g, and reflecting a weight increase of 2901,37g; a crude protein intake of 16,47 g/ a day; a metabolizable energy of 294,02 kcal/ a day; an efficient alimentary conversion of 2,37 points; a weight at canal of 3127,0 g, the yield at carcass of 68,61%, and it also reflected minimal lost because of lessening for feather which account for 13,39%, for blood lessening which account for 3,54% and for entrails lessening accounting for 10,12%. Therefore this quinua energetic density level was reflected in the crude protein existing in the meat and in a percentage of the intramuscular fat which account for 1,65%; the meat cost/kg of 0,89 USD and a benefit cost of 1,53 USD. From these study results we can conclude that the fattening diet at 3.206 Kcal of ME/kg is advisable to feed the capon commercial chicken since it gives the best economic and productive yield.
