Comportamiento productivo de pollitas de la línea lohmann brown en la fase de postura - pico de producción (18-26 semanas) alimentadas con diferentes niveles de proteína de origen animal.

Abstract

The productive behavior of pullets of the line Lohmann Brown in the phase of posture-peak production (18-26 weeks) fed with different levels of protein of animal origin, the chemical composition of the experimental diets was determined with 2, 4, 6% of Proteika, analyzing the production cost of each treatment; With an experimental methodology, in the poultry research academic unit at the Animal Science Faculty, of the Polytechnic Scholl of Chimborazo, with a completely randomized design in which three trials were used and a controlled trial of four repeated screenings each one, consisting of 25 pullets per each experimental unit resulting in a total of 400 birds over a periodo of 64 days. Significant differences were recorded (P<0,01) in the productive patterns, being the most effective trial the 6% protein inclusión (T3) with a consumption 20,29 ± 0,10 g/day, energy consumption 264,16 ± 1,45 kcal/day, instead, the best cost-benefi procedure was the 4% Proteika inclusión (T2) with 1,082 USD and a profitability of 8%. It is concluded that 4% Proteika. In addition, it is highly recommended to poultry farmers to implement this flour in the feed intakes, since it allows a better growth development of the poultry, while ensuring an adequate production through the whole laying stage.
