- ÍtemAcceso AbiertoEfecto de microorganismos benéficos sobre los niveles de amoniaco y digestibilidad alimenticia en pollos Broiler(Universidad Católica de Cuenca., 2024) Briseño Mejía, Banner Giovanni; Vázquez Vásquez, Jacinto Enrique; 1150598645The current research aimed at evaluating the effect of adding beneficial microorganisms in the drinking water and on the poultry house floor on ammonia levels and feed digestibility parameters in broiler chickens. Six hundred 1-day-old broilers were distributed under a completely randomized design; the treatments to be evaluated were T0 (control) and T1 (0.1% beneficial microorganisms), each with four replicates and 75 experimental units. The variables evaluated were production parameters (weekly weight, feed consumption, weight gain, feed conversion, carcass weight, mortality percentage), feed digestibility (crude protein, organic matter, inorganic matter), and ammonia levels inside the poultry house. The results showed that T1 increased weight gain and improved feed conversion in week 1, feed digestibility was affected in ash and protein, and mortality percentage decreased. However, carcass weight was not affected. Finally, ammonia levels inside the house did not show significant differences between treatments during the research. In conclusion, the addition of beneficial microorganisms at a rate of 0.1% in the drinking water and the broiler poultry house do not have a positive impact on the levels of ammonia inside the poultry house. However, it increases weight gain and bird feed conversion and decreases the percentage of mortality. Keywords: Beneficial microorganisms, production parameters, broiler chicken
