The Potency of Probiotics and Acidifiers on Body Weight, Feed Efficiency, Cholesterol, HDL, LDL in Meat of Broiler Chickens Infected with Escherichia Coli

초록

This study aims toevaluatethe effects of adding probiotics and acidifiers to feed as alternatives to antibiotic growth promoters (AGP) in broiler chickens infected with Avian Pathogenic Escherichia coli (APEC) concerning body weight, feed efficiency, meat quality, cholesterol, HDL, and LDL levels in chicken meat. Research method: preparation of experimental animals in vivo. The use of probiotics and acidifiers is used as a potential solution to improve intestinal health and optimize nutrient absorption. This study employed a Completely Randomized Design, consisting of six treatments, each with five replications, with each replication including two chickens, resulting in a total of sixty chickens used. The treatments are as follows: P0 = Broiler chickens without E. coli infection (Control -); P1 = Broiler chickens infected with E. coli (Control +); P2 = Broiler chickens infected with E. coli + AGP; P3 = Broiler chickens infected with E. coli + Probiotics; P4 = Broiler chickens infected with E. coli + acidifiers; P5 = Broiler chicken infected with E. coli + Probiotics + acidifiers. The observed variables included body weight, feed efficiency, cholesterol, HDL, and LDL levels in broiler chicken meat. The data obtained were then analyzed statistically using one-way Analysis of Variance (ANOVA). If the results were significantly different (p < 0.05), Duncan’s multiple range test was conducted. The results indicated that the addition of probiotics and acidifiers could increase body weight, enhance feed efficiency, and reduce cholesterol, LDL and improve HDL levels, all with significant effects (p < 0.05). © 2025 by the authors.
