    Evaluación del butirato de sodio sobre los índices productivos y morfometría de las vellosidades intestinales en pollos de engorde
    (2024-08) Izurieta Buenaño, Sofía Anahí; Guerrero López, Jorge Ricardo
    The present research project evaluated the effects of sodium butyrate (SB) on productive indices and intestinal (duodenal) villi morphometry in broilers. A total of 400 one-day-old Cobb 500 male chickens were divided into 5 treatment groups, each with 4 replicates, in a completely randomized design; The diets were formulated as follows: T0 (-) (control), T1 (0.05% BS), T2 (0.10% BS), T3 (0.15% BS) and T4 (+) (0.05% flavomycin). During the entire experimental period (42 days), inclusive, in the 4 evaluation phases (pre-initial, initial, fattening and finishing), the chickens did not show statistically significant differences between treatments (p>0.05) on the productive indices (final weight, weight gain, feed consumption and feed conversion ratio); Similarly, no statistically significant differences (p>0.05) were found for the variables crypt depth, duodenal villus length and width on days 21 and 35. However, according to the cost: benefit (C/B) ratio, T1 and T3 showed a higher profit (9 cents per dollar invested), followed by T0 (6 cents), T4 (3 cents) and T2 (2 cents). In conclusion, the addition of BS does not improve the productive indices and duodenal villus morphometry of Cobb 500 chickens, although it is estimated that it shows a greater economic benefit.
