Afegir etiqueta | Sumari: | This research arose with the purpose of reducing feed costs in the production of broiler chickens and taking advantage of agroindustrial waste, corn was replaced with 2 levels (10 and 20%) of potato peel flour in the feeding of broiler chickens. fattening, for which the physical, chemical and microbiological characterization of the potato peel flour and the balanced ones is carried out, the energy contribution of this by-product was determined, in turn the productive parameters were evaluated and an estimate of the economic merit was made. in the production of broilers fed with potato peel meal during the growing and finishing stage. This research was carried out in the Province of Cotopaxi, Cantón Salcedo, Parroquia Mulalillo, 198 chickens from the Cobb 500 line, 21 days old, with an average weight of 670.02g, were used, randomly distributed in 3 treatments, 11 repetitions and 6 experimental units. In each repetition, the following diet was applied: T0 (commercial balanced), T1 (10% potato peel flour) and T2 (20% potato peel flour). For the interpretation of the data obtained, ANOVA and the Bonferoni test were applied to identify statistical differences between treatments, obtaining the following results: when carrying out the physical, chemical and microbiological characterization of the potato peel flour, a total of 9.64 % in protein and 1.39% in fat, in addition the absence of all types of pathogenic bacteria is reported, it was determined that potato peel flour provides 1870.6162 Kcal/kg MS of energy, when evaluating the productive parameters it stands out T1(10%) with 2405.17g average weight, 973.73g in feed consumption, 589.86g in weight gain and 1.68 in feed conversion, economic gains of $0.28 were obtained for every dollar invested. Therefore, it is concluded that potato peel meal can be a feed alternative to improve feed costs in broiler chicken production. |
