Efecto de la adición de sustratos glucogénicos sobre los parámetros productivos en pollos de engorde.

Abstract

The objective of this research was to implement glycogenic substrates in the daily diet as a nutritional additive in broiler chickens in Santo Domingo de los Tsachilas City. In the research 540 chickens of the Cobb 500 line were used, received at 1 day of age until 42 days (initial stage, growth, fattening and completion) and of an average weight of39,03 g. Two glycogenic substrates were used to be compared with a control treatment. A completely randomized design (CRD) was applied with 10 repetitions and the size of the experimental unit of 18 animal.s, it means., we worked with 180 animals in each of the treatments. The nutritional contribution of the treatments was similar, meeting all the nutritional requirements required by the birds according to their physiological stage. The T2 glucogenic substrate presented better production parameters, with a final weight of 2893,89 g, total weight gain 2854,61 g, daily weight gain 67,97 g, total feed consumption 4476) 8 g, feed conversion of 1,57, viability 97,22 % and uniformity of 100,0 %. It was concluded that the best cost benefit was 1,29 when using the T2 glucogenic substrate. Jt is recommended to include in the feed of broilers during the initial stage, growth and fattening, the glucogenic substrate T2.
