Evaluación de un simbiótico nativo formulado a base de jugo de caña, yogurt natural y suero de leche en la alimentacíón de pollos broiler

Abstract

The research was conducted in the Program Poultry Research of the Faculty of Livestock Sciences of the ESPOCH, Riobamba Ecuador, three levels of a Native Symbiotic, 2% (T1), 4% (T2) and 6% (T3) was studied, in the drinking water, compared to control treatment (CT), whose objectives were 1) Evaluation of the biological behavior of broiler chickens fed different levels of native symbiotic as part of the diet. 2) Determination of the symbiotic effect on the physiological status and health of birds. 3) Calculate the costs of costs of production and profitability of each of the treatment. Under a completely randomized desing (CDR) Each treatment consisted a total of 10 birds with 3 repetitions for a total of 120 birds, with two replications, meaning they had to research a total of 240 birds, to which is supplied, according to the daily food physiological stage the symbiotic was added to drinking water and were determined: productive indicators, biological, medical and economic behavior. The experimental results were submitted: to the analysis of variance (ADEVA), Tukey test (P≤0.05) and (P≤0.01). For the separation of average, even regression and correlation. Thus it was determined that in the initial phase (1 – 21 days), chickens subjected to T3, obtained live weight at 21 days of 704.33 g; weight gain of 662.23 g: feed conversion of 1.1 the same way in the growth phase (21 – 35 days) 1607.0 live weight g was reached; 902.67 weight gain, feed conversion of 1,54, mortality of 1.18% and the fattening phase (35 -49 days) was achieved, a final live weight of 2993.67 g; weight gain g 1586, 67, feed conversion of 1.41 to channel yield 71.63%. Besides using T3, the presence of E.coli and Salmonella sp, was zero at the intestinal content; bacterial load of intestinal lactic acid was UFC.ml-1 16420000, with an acid pH4.5. The best index of benefit/cost was 1.39 that is a profitability of 39%. Based on the results it is recommended in drinking water 6% native symbiotic, in the production of broiler chickens
