“…Although organic acids are less efficient than antibiotics, several studies prove their efficiency against Campylobacter (Chaveerach et al, 2002 ; Heres et al, 2004 ; Skånseng et al, 2010 ; Guyard-Nicodéme et al, 2016 ), Clostridium (Timbermont et al, 2010 ; Mohamed et al, 2014 ), Eimeria (Abbas et al, 2011 ; Ali et al, 2014 ), Escherichia (Ozduven et al, 2009 ; Panda et al, 2009a , b ; Roy et al, 2012 ), and Salmonella (Van Immerseel et al, 2004 ; Fernández-Rubio et al, 2009 ; Menconi et al, 2013 ). Moreover, Goualié et al ( 2014 ) demonstrated the antibacterial ability of organic acids against resistant strains of Campylobacter to antibiotics that are commonly utilized in the treatment of campylobacteriosis in humans, characterizing organic acids as an alternative to minimize the problems caused by the use of antibiotics. The effect of organic acids can be explained by the lipophilic ability of these molecules to cross the cell membrane of bacteria and dissociate themselves in the more alkaline inner part, acidifying the cytoplasm and consequently impairing the cellular metabolism.…”

The effect of organic acids as an alternative to antibiotics on the performance of broiler chickens was evaluated by meta-analysis, identifying and quantifying the main factors that influence results. A total of 51,960 broilers from 121 articles published between 1991 and 2016 were used. Interactions of additives [non-supplemented group (control), organic acids, and growth promoter antibiotics] with microbial challenge (with or without inoculation of pathogenic microorganisms) were studied on performance variables. Moreover, the effects of organic acids, used individually or in blends, were evaluated. Relative values of average daily gain (ADG) and average daily feed intake (ADFI) were obtained in relation to control: ΔADG and ΔADFI, respectively. Analysis of variance-covariance revealed lower ADG with organic acids when compared to antibiotics (P < 0.05). There was a significant interaction between the additives and the challenge on feed conversion ratio (FCR) (P < 0.01) and on viability (P < 0.05). Without challenge, organic acids improved broilers’ FCR (P < 0.01), presenting results similar to antibiotics (P > 0.05). Under challenge, the organic acids were again effective on FCR (−5.67% in relation to control, P < 0.05), but they did not match antibiotics (−13.40% in relation to control, P < 0.01). Viability was improved only under challenge conditions, and only by antibiotics (+4.39% in relation to control, P < 0.05). ADG (P < 0.05) and FCR (P < 0.01) were increased by blends of organic acids, but not by the organic acids used alone (P > 0.05). ADFI and production factor were not influenced by the treatments (P > 0.05). ΔADFI of organic-acid supplemented group showed a linear influence on ΔADG, which increases 0.64% at every 1% increase in ΔADFI. In conclusion, organic acids can be utilized as performance enhancing, but the results are lower than those found with antibiotics, particularly under microbial challenge. The blends of organic acids provide better results than the utilization of one organic acid alone.

Introduction: Campylobacter jejuni is one of the major causes of gastroenteritis worldwide of the last century. The aim of this study was to investigate the antibiotics profiles and the virulence gene in C. jejuni strains isolated from chicken in Côte d’Ivoire. Methodology: A total of 336 chicken ceaca samples recovered from market of two municipality of Abidjan were examined by conventional microbiological methods and molecular test using PCR. The antibiotic susceptibility tests of the isolates were determined by disk diffusion method. The presence of virulence genes was examined using simple PCR method. Results: Among of 336 samples, 168 (50%) were positives for C. jejuni. Among the C. jejuni isolates, 159 strains (94.64%) were resistant to one or more antimicrobial agents. The highest percentage of antimicrobial resistance was found for Nalidixic acid (85.33%), Tétracyclin (71.76%) and Ciprofloxacin (55.65%). Moreover, MDR including 3, 4, 5 and 6 antibiotics families was detected in 16.66% of isolates. On the other hand, detection of virulence putative gene shows presence of cadF in 100% of tested strains. In addition, cdtA, cdtB and cdtC genes were detected in 100%; 89.51% and 90.32% respectively of C. jejuniisolates. Conclusion: Because of the key role of broiler chicken in human campylobacteriosis infection, it will important in first time to monitoring using of antibiotics in chicken farms and in second time to verify presence of campylobactériosis in country.

“…The results of the studies by Roth (2015) and Roth et al (2017) supported our above findings. According to Goualié et al (2014) , using organic acids in the poultry production chain can reduce the propagation of antibiotic multiresistant strains of Campylobacter . However, an obvious reduction in the quantity of selected antibiotic resistance genes by the acid-based feed additive for weaned piglets was not detected in the study by Wegl et al (2017) , while clear effects of the oxytetracycline feed supplementation on the resistance gene prevalence and quantity were observed.…”

“…Positive effects of acids are associated mainly with increased gastric acidity, antibacterial activity, reduced coliform populations, and improved digestibility ( Jensen et al, 2003 ; Devi et al, 2016 ), resulting in an improvement in the performance and feed efficiency of fattening pigs ( Partanen and Mroz, 1999 ; Overland et al, 2000 ; Devi et al, 2016 ). Several studies show that certain organic acids can inhibit the growth of multiresistant bacteria and that they can act against bacterial biofilms, which cannot be achieved by antibiotics ( Goualié et al, 2014 ; Akbas and Cag, 2016 ). To study the emergence of antibiotic resistance (AR) in gram-negative bacteria, Escherichia coli are widely accepted as indicator bacteria ( Kaesbohrer et al, 2012 ).…”

This study was carried out to evaluate the effect of Selacid Green Growth (GG) or antibiotic growth promoter (AGP) on the performance and economics of grow-finish (GF) pigs. The Selacid GG is a blend of short chain fatty acids (formic acid, acetic acid, lactic acid, propionic acid, citric acid, sorbic acid), buffered organic acid (ammonium formate), and a combination of medium chain fatty acids (C8, C10, and C12). A total of 312 grower pigs (Yorkshire × Landrace × Duroc) with an initial body weight (BW) of 26.5±0.92 kg was used in a 90-day feeding trial. The pigs were allocated randomly to three treatments consisting of 8 replicate pens with 13 pigs each. The treatments tested included a (1) Negative Control (control): basal diet without Colistin and Selacid GG, (2) Positive Control (AGP): basal diet with Colistin (20 g/ton), (3) Feed additive (Selacid GG): basal diet with Selacid GG (2 kg/ton). The results showed that over the entire period of the experiment, the dietary supplementation of Selacid GG elicited a similar effect as AGP on feed cost and on all growth parameters measured (P>0.05). In relation to the control group, Selacid GG significantly improved the final BW (+3.4 kg or 3.6%), average daily gain (ADG) (+39 g/pig or 5.3%) and Gain:Feed (+30 g or 8.1%) of pigs (P<0.05). In addition, the feeding of Selacid GG reduced feed cost (−0.078 USD) per kilogram BW gain. The average daily feed intake was not affected by the dietary treatments (P>0.05). E. coli was prevalent in 46 out of 48 fecal samples tested. All E. coli isolates were resistant to Colistin, Amox-Colistin, Ciprofloxacin and Enrofloxacin. The number of E. coli isolates resistant to Amoxicillin/clavulanic, Cefotaxime, Ceftiofur and Norfloxacin was significantly reduced; whereas the inhibitory zones of Amocxillin/clavulanic acid were increased; and the susceptibility of E. coli to Amoxcillin/clavulanic, Cefotaxime, Ceftiofur, Ciprofloxacin, Nofloxacin and Flumequin was increased when Selacid GG was added in the feeds (P<0.05). The findings of the study suggest that Selacid GG is a cost-effective product with the same efficacy as AGP in promoting the growth and economic performance of GF pigs. The product is safe and can be added in the diet of GF pigs without developing resistance to selected antibiotics.
