Evaluación económica y productiva de dietas altas en fibra de pollos Broiler bajo sistemas de producción en altura de la Universidad Nacional de Loja “extensión Punzara.

Abstract

The objective of this research was to evaluate the economy and production with a high fiber diet in Broiler chickens under a high altitude production system at the National University of Loja "Punzara Extension. The research was evaluated using the observational study method, applying measures of central tendency and dispersion, and to plot the percentages, bar graphs were used for each of the confidence intervals. The numerical field results were tabulated in the Excel office 2016 program. For data analysis, descriptive statistics were used as central tendency, among which mean, median and mode were calculated, and dispersion as standard deviation. The chickens were placed in a house to be fed from day 1-13 with a commercial diet that complied with the nutritional recommendations, from day 14 to 25 they were fed a fibrous growth diet and with a restriction of 10% of the protein and metabolizable energy requirements with respect to the requirements for growth of the genetic line, from day 26 to 42 a fattening diet was formulated. The results of the statistical variables were initial weight (41.37 g); weekly weight (162.10 g): final weight (2733.40 g); total weight gain (61.22 g); total feed consumption (41257.02 g); feed conversion (1.81); carcass yield (93.06%) and mortality rate was 0.14%, obtaining a benefit/cost of 1.70 USD. It is concluded that the productive and digestive parameters do improve in birds with fibrous diets. It is recommended to study the inclusion of other fiber sources to modulate broiler growth.
