Evaluación de tres niveles de Oligosacáridos Mánanos (Saccharomyces cerevisiae) adicionados en dietas balanceadas de Lechones post destete, en la granja porcícola “San Francisco”, Arenillas, El Oro.

SUMMARY The objective of this work was to evaluate the effect of three levels of Mannan-Oligosaccharides (Saccharomyces cerevisiae) in the post-weaning piglets phase. A completely random design "D.C.A" was used with 3 treatments and 4 repetitions plus an absolute witness, 2 pigs for each experimental unit with a total of 32 pigs. The verification of the measurement of the treatments was carried out with the Tukey test (P˂0.05), the statistical program InfoStat version 2018e was used. Three levels of Mano Oligosaccharides were evaluated (T1=1,5Kgt-1 T2=1,5Kgt-1, T3=3Kgt-1). The variables studied were: Body weight, average food consumption, feed conversion, average weight increase and cost benefit ratio. The productive parameters analyzed with the Tukey P test <0.05, showed significant differences between treatments. The levels of T2 (1,5 Kgt-1) of Mannan-Oligosaccharides added in balanced diets of piglets after weaning, showed higher weights (31.45 kg) in relation to the treatments T0 (witness) and T3 (3 kg), (30,76; 27,24 kg) in the sixth week of the experiment. Higher feed intake was obtained without the addition of Mannan-Oligosaccharides (12,69 kg) in the diet during the sixth week. Greater weight gain obtained the T0 (Witness) in the weeks: one 2,78 kg; two 2,78kg, four 3,93kg, and five 4,65kg. In addition, gain was obtained with the diet of T2 (1,5 kg) of Mannan-Oligosaccharides in week three 4.24 kg, and T1 in the sixth 5,15 kg. Better feed conversion is achieved with the addition of T2 (1,5 kgt-1), (2,39 kg / kg) of Mannan-Oligosaccharides in the diet, in the sixth week of the experiment and Best cost benefits ratio reached T2 (1,5 kgt-1), ($ 1.32) in the diet. Keywords: Oligosaccharides Mánanos, weights, treatment, pigs, food.
