“…(2013) found better results to reduce ST in the crop and cecal tonsils ( CT ) using a blend of acetic, citric, and propionic acids at a final concentration of either 0.031 or 0.062%. Similarly, supplementing organic acid blends with oregano extract in water at 0.08% and in feed at 0.2% significantly reduced the shedding of Salmonella Enteritidis at 22 and 42 D of life, although this combination did not reduce the prevalence in crop at slaughter age ( Machado Jr. et al., 2014 ).…”

Feed additives can be alternatives to antibiotics for routinely encountered pathogens in the poultry production. The objective of this study was to understand effects of organic acid mixture on growth parameters and Salmonella Typhimurium ( ST ) colonization in broilers. Organic acid mixture is a feed-grade buffered formic acid and sodium formate mixture (Amasil NA). A total of 800 1-day-old Cobb500 males were fed one of the five dietary treatments: a negative control diet without ST challenge ( NC ), positive control diet with ST challenge ( PC ), 0.3% organic acid mixture with ST, 0.6% organic acid mixture with ST, and 0.9% organic acid mixture with ST. Treatments were assigned to 20 pens with 40 chicks/pen and 4 replicates of each treatment. Chickens were challenged with 10 7 CFU/mL of nalidixic acid–resistant ST ( ST NAR ) 4-D posthatch. In the grower phase, feed conversion rate was significantly reduced in the 9% organic acid mixture compared with the PC. The body weight and body weight gain ( BWG ) were not affected either in the starter or grower phases. However, in the finisher phase, the nonchallenged NC had higher BWG than the PC ( P < 0.05), whereas there were no differences in BWG among the NC and organic acid mixture fed groups. In addition, there was a significant effect of organic acid mixture on the colonization of cecal ST NAR . At 9 dpi, cecal ST NAR was 3.28 log 10 in the PC that was reduced to 2.65 log 10 at 0.3%, 1.40 log 10 at 0.6%, and 0.84 log 10 in 0.9% organic acid mixture. At 24 dpi, cecal ST NAR recovery was 0.81, 0.99, 0.53, and 0.33 log 10 in the PC and 0.3, 0.6, and 0.9% organic acid mixture, respectively. Similarly, at 38 dpi, cecal ST NAR was 0.26, 0.11, 0.33, and 0 log 10 in the PC, 0.3, 0.6, and 0.9%, respectively. These results show that organic acid mixture can be one dietary strategy to control ST infection and maintain efficient growth performance.

Phytogenic Compounds for Enhancing Intestinal Barrier Function in Poultry–A Review

et al. 2021

View full text Add to dashboard Cite

After the European Union ban of antibiotic growth promoters, works on different methods of improving gut health have intensified. The poultry industry is struggling with problems that were previously controlled by antibiotic growth promoters, therefore the search for optimal solutions continues. Simultaneously, there is also increasing social pressure to minimize the use of antibiotics and replace them with alternative feed additives. A variety of available alternatives is considered safe by consumers, among which phytogenics play a significant role. However, there are still some limitations that need to be considered. The most questionable are the issues related to bioavailability, metabolism of plant derivatives in birds, and the difficulty of standardizing commercial products. There is still a need for more evidence-based recommendations for the use of phytogenics in livestock. On the other hand, a positive influence of phytogenic compounds on the health of poultry has been previously described by many researchers and practical application of these compounds has auspicious perspectives in poultry production. Supplementation with phytogenic feed additives has been shown to protect birds from various environmental threats leading to impaired intestinal barrier function. Phytogenic feed additives have the potential to improve the overall structure of intestinal mucosa as well as gut barrier function on a molecular level. Recognition of the phytogenicsʼ effect on the components of the intestinal barrier may enable the selection of the most suitable ones to alleviate negative effects of different agents. This review aims to summarize current knowledge of the influence of various phytogenic constituents on the intestinal barrier and health of poultry.

“…A commonly trialled combination was that of organic acids and phytogenic products. Multiple studies found that a combination of organic acid and phenolic plant products could be effective as feed or water additives against Salmonella in broilers relative to untreated controls [106,110,[126][127][128]174,190]. It is unclear if the combination effect is synergistic however: two studies [102,107] did not find any further reduction in Salmonella when broilers were treated with a phytogenic /organic acid combination additive relative to treatment with the organic acid alone.…”

Enteropathogens, namely Salmonella and Campylobacter, are a concern in global public health and have been attributed in numerous risk assessments to a poultry source. During the last decade a large body of research addressing this problem has been published. The literature reviewed contains review articles on certain aspects of poultry production chain, however in the past decade there hasn’t been a review on the through production chain, farm to fork, production of poultry. This review, a pool of 514 articles were selected for relevance via a systematic screening process (from >7500 original search articles). These studies identified a diversity of management and intervention strategies for the elimination or reduction of enteropathogens in poultry production. Many studies were laboratory or limited field trials with implementation in true commercial operations being problematic. Entities considering using commercial anti-enteropathogen products and interventions are advised to perform an internal validation and fit for purpose trial as Salmonella and Campylobacter serovars and biovars may have regional diversity. Future research should focus on non-chemical application within the processing plant and how synergistic through chain intervention may contribute to reducing the overall carcass burden of enteropathogen, coupled with increased consumer education on safe handling and cooking of poultry.
