Comportamiento productivo en la engorda de tilapia gris alimentadas con dietas a base de Colacasia esculenta en el Puyo Ecuador

Abstract

In the province of Pastaza, Puyo, Km 6 Via August 10, 1440 the productive performance of tilapias fed with different proportions of potato leaf China in the growing stage was evaluated. Tilapia were distributed in 2 tanks divided into 24 compartments with 4 treatments and 6 replications, under a completely randomized design (DCA), the treatments were: T1 (commercial feed), T2 (20% HPC), T3 (30% HPC) and T4 (40% HPC). The parameters evaluated were: length and initial and final weight, weight gain / day (g), Daily Growth (mm / day), FCR, Profitability and cost / benefit ratio. The test duration was 60 days. In weight gain no significant differences (P = 0.0950) between treatments maintaining a range between 5.81 to 6.17 g / day gain. The daily growth of tilapia was observed that the greatest growth was in Q4 (0.20 mm / day) being different (P = 0.0084) at T1 (0.10 mm / day). The best feed conversion no significant differences (P = 0.1952) while maintaining a range of 2.41 to 2.54. With respect to profitability and cost / benefit ratio indicated that T4 was higher with 33,40% of profitability and benefit / cost ratio was 1.50. The results suggest that the use of leaf Papa China, which is an important industrial waste could have a potential use in food processing for Tilapia.
