Comportamiento productivo de gallinas lohmann brown de la 27 a la 51 semana de producción por efecto de tres niveles de proteína de origen animal.

Abstract

The productive behavior of hens of the Brown Lohmann line from the 27th to the 51th week of production was evaluated by effect of three levels of animal protein, the chemical composition of the experimental diets was determined with 2,4,6% levels of Proteika, in addition, the costo of production of each treatment was analyzed; with an experimental methodology in the Poultry Research Academic Unit of the Faculty of Animal Sciences, of the Polytechnic Scholl of Chimborazo, under a completely random design for which three treatments and a control treatment with four repetitions each were used, forming each experimental unit for 24 hens giving a total of 396 birds under study for the course of 175 days. Significant differences (P<0,01) were recorded for consumption, being the best treatment with 6% inclusión of Proteika (T3) with consumption of dry matter 100.45 ± 0,61g, protein consumption 23,88 ± 0,13 g/day; energy consumption 313,48 ± 1,91 Kcal/day, egg production 95,26 ± 1,05%, the treatment with the best cost benefits was T3 with 6% inclusión of Proteika with 1,25 USD and a profitability of 25%. It is concluded that Proteika uses flour, the best tratment obtained for a good egg production is T3. It is recommended to the eggs producers the implementation of Proteika in their rations since it allows a better development of the bird both anatomically and physiologically, also substantially increases egg production.
