Efecto de la inclusión de probióticos en indicadores de salud y producción en lechones post-destete

This study evaluated the use of probiotics (Lactobacillus acidophilus, Saccharomyces cerevisiae, and Bacillus subtilis) and their effect on the well-being and productivity of piglets in the Miguel de Sarampión area. An experimental research with a mixed approach was developed over 20 weeks, involving a population of 28 pig farms. Four experimental units with 10 piglets per treatment were considered (T0: weaning at 35 days and T2: weaning at 45 days as the control group; T1: probiotic+weaning at 35 days and T3: probiotic+weaning at 45 days) with a completely randomized block design and an α value of 0.05. The results indicate that the weaning times most frequently applied in the farms of the area exceed 45 days of age. It was found that the use of probiotics in piglets led to a highly significant increase in weight in the first week, where T1 (p<0.0155) achieved 2.36 kg; T3 with (p<0.001) achieved 4.83 kg in week 2, 7.08 kg in week 3, 9.25 kg in week 4, and 11.43 kg in week 5, surpassing the other treatments. In weekly weight gain, a (p<0.001) was recorded in all weeks: T1 presented 0.79 kg in the first, T3 presented 2.54 kg in the second, T3 presented 2.25 kg in the third, T1 presented 2.30 kg in the fourth, and T0 presented 2.65 kg in the fifth. The use of probiotics resulted in the absence of morbidity and mortality, and in the economic analysis, T3 achieved a 40% profitability, making it a viable option to include in post-weaning pig diets in pig farming.
