“…Under challenge conditions with Salmonella Enteritidis, Pickler et al (2012) also found no difference in broiler performance (FI, WG, and FC) of broilers from one to 21 days of age that received a commercial organic acid mixture (14% lactic acid, 4.5% fumaric acid, 5.0% citric acid and 1% formic acid) in the feed and a mixture of commercial organic acid in the feed and drinking water (27% fumaric acid, 28% citric acid) concerning negative control group. However, Calaça et al (2019) in their studies, evaluated the action of a compound of organic acids (acetic, formic, and propionic) in the proportion of 4 kg per ton of feed of birds challenged with Salmonella Enteritidis and Eimeria tenella, found little bacterial action in their isolation of SE in the spleen and cecal tonsil compared to groups that did not receive acids in the feed, promoting improvements to intestinal health with positive actions in the control of Salmonella Enteritidis together with Eimeria tenella.…”

The objective of this experiment was to evaluate the benefits of acetic acid in different periods of inclusion in broiler drinking water on broiler performance, pH, and microbiota, especially the morphometry of the jejunum of broiler chickens. For this, 240 chickens of the Cobb500® lineage of 21 days of age were used and distributed in boxes in an experimental broiler house, considering a completely randomized design, with four treatments and four replications of 15 birds each (experimental unit). The treatments were: T1 - Control (chlorinated water at 3 ppm); T2 - chlorinated and acidified water with acetic acid in the period from 21 to 42 days of age; T3- chlorinated and acidified water with acetic acid in the period from 28 to 42 days of age; T4 - chlorinated and acidified water with acetic acid in the period from 35 to 42 days of age. The results were analyzed using Analysis of Variance, followed by Tukey's post-test, considering a significance level of 5%. No differences in performance were observed in the period from 21 to 42 days of age, pH, and Lactobacillus spp. counts of the crop at 42 days of age and height of villi and jejunum crypt depth in the same age. However, there was a reduction (P<0.05) in the enterobacteria count in the crop at 42 days of age, which could contribute to the reduction of intestinal enterobacteria counts and, in turn, reduce the contamination of the carcass of broiler chickens.

Feed additives have a strong influence on the production cost of broilers as growth-promoter’s to cover variations in profits due to fluctuation in feed costs. Antibiotics as additives were fundamental and indispensable, however, studies have shown their connection with the emergence of resistant strains of pathogens in animals and humans, therefore in recent years they have been less encouraged. Research is in progress concerning additives that can replace antibiotics as growth promotors and also as prophylactics. It was demonstrated that probiotics, which are living microorganisms and without residual effect’s have a potential to be used as microbials. However, they are not always guaranteed as growth promoters, as there are mechanisms of action regarding their interaction with the host that cannot yet be properly understood. The main advances in the use of probiotics in broilers in recent years, as well as the gaps, challenges, and future perspectives were carefully discussed and analyzed in this study. It was considered as a future premise, the possibility of reviewing the traditional methodologies used to test the hypotheses related to the effect of probiotics in broilers, which may also be extended to other animal species.
