Utilización de probióticos como alternativa para el mejoramiento productivo en pollos de engorde.

Abstract

The study, titled "Use of Probiotics as an Alternative for Improving Productivity in Broiler Chickens," aimed to analyze the influence of probiotic supplementation on mortality rates and productive performance in broiler chickens. The research was conducted in barn 1 of Granja Villa Liliana, owned by AVSA S.A., using two batches: batch 189 (control group, without supplementation) and batch 190 (experimental group, with probiotic supplementation). The methodology was quantitative, comparative, and experimental. Mortality rates were monitored weekly, and production indicators such as feed intake, weight gain, and feed conversion ratio were analyzed. The results showed that batch 190, supplemented with a probiotic mixture of Butyricicoccus pullicaecorum, Lactobacillus acidophilus, Bacillus subtilis, Bacillus licheniformis, Streptococcus faecium, and Saccharomyces cerevisiae cell wall, had a 50% lower cumulative mortality rate, greater weight gain, and 11% higher feed conversion efficiency than batch 189. It is concluded that probiotic supplementation significantly improves health and production performance, making it a viable alternative for reducing losses and optimizing poultry production.
