Lasit fáddágilkoriid | Čoahkkáigeassu: | Determination of the effects of different doses of non-starch polysaccharides in broiler chickens, the following specific objectives were proposed: I) Determine the optimal dose of non-starch polysaccharides in the development of broiler chickens; II) Carry out an economic analysis benefit / cost ratio. This investigation was carried out in the experimental farm Laguacoto II, Guaranda, province of Bolívar. In Ecuador there are a total of 1,236 poultry farms with a production of 28.7 million broiler chickens, the main producing provinces are: Pichincha, Guayas, El Oro and Imbabura with 7.9, 7.6, 2.3 2 million tons respectively, while the province Bolívar has a production of 56.8 kg; in the livestock sector, especially in intensive poultry farming, we are technifying and applying additives such as non-starch polysaccharides that help improve performance at a shorter time (ideal weight / 5 weeks) and increasing the profitability of poultry farmers, due to their good appearance to the consumer, lean meat of good color, softness of the meat. The altitude of this zone is at 2640 meters above sea level; its average annual temperature is 14.4 ° C, with 900 h / l / year and 70% relative humidity; the doses of PNAs in this investigation were: 0%, 10%, 15% and 20% of these enzymes, the statistical model used was a completely randomized design. The results obtained in this investigation showed statistical significance (*), it was determined that the dose at 20% (T4) presented a higher productivity compared to the other doses under study, both in Food Conversion (CA), Weight Gain (GP) and Weight to the Channel (PC), presenting a general average of 1.09, 3031.14 gr, 2617.89 gr; and coefficients of variation (CV) of less than 20% were obtained in all its variables |
