Utilización del Zingiber officinale (Jengibre) como promotor de crecimiento en la alimentación de alevines fase II de la Empresa Pesca Deportiva Reina del Cisne en la provincia del Azuay

Abstract

At the Sport Fishing Enterprise Reina del Cisne located in the Dos Chorreras sector km 21 on the way to Cajas, Azuay Province, mean (8˚C), maximum (16˚) temperatures, pH ( 6.9 ˗ 7), nitrates (0.06 mg/L), Nitrites (˂ 0.0002 mg/L) Solved Oxygen (7.4mg/L) were identified. The study was carried out with the use of different ginger levels (0.2, 0.4 and 0.6%) as a growth promoter in the daily feeding of alevins in phase II. A completely at random design was applied with three treatments compared to the control treatment, and 5 replications with aa total number of experimental units of 5000 alevines and a distribution 250 per pool. The highest results are reported with the inclusion of 0.6% ginger flour (T3) thus increasing the productive yields such as: final weights (4.10 g), total weight gain (3.37g), final size (6.03 cm),total feed consumption (3.87g/ms), efficient alimentary conversion (1.03 points ) and a low mortality of 8.43%. The highest benefit˗ cost index was 1.90 USD, i.e. a 90% profitability. Therefore, it is suggested to include 0.6% ginger flour as it improves the productive and economic profitability parameters for the producer of alevines of phase II of the rainbow trout.
