“…Additionally, according to the literature, UFAs could reduce the incidence of human cardiovascular diseases [41] Thus, efforts to decrease the content of SFAs and enhance the content of UFAs are anticipated. In our findings, an increased level of UFAs and a reduced level of SFAs as well as an improved ratio of PUFAs to SFAs in the meat of broilers supplemented with LMOA were observed, which was parallel with Galli et al [8], who indicated that dietary microencapsulated organic acids lowered the level of SFAs and increased the level of UFAs in broiler meat. This phenomenon probably resulted from the involvement of some components of MOA in fatty acid metabolism in the liver, reducing the process of ab initio synthesis of fatty acids, as well as the increased synthesis of desaturases ∆5, ∆6 [42] and ∆9 [27].…”

Background: Organic acid as a green feed additive is increasingly favoured by enterprises and scholars, but little emphasis has been placed on the effect of organic acids on broiler meat quality. Methods: A total of 192 male chicks (one-day-old, weighted 48.40 ± 0.64 g) were selected to investigate the effect of mixed organic acids (MOA) on growth performance, meat quality as well as fatty acids profile. Chicks were randomly allocated to three treatments with eight replicates and eight chicks per replicate, including a corn–soybean basal diet with 0 (CON), 3000 mg/kg (low MOA; LMOA), and 6000 mg/kg (high MOA; HMOA) MOA. The experiment was divided into starter (d 1–d 21) and grower (d 22–d 42) phases. Results: Broilers supplemented with LMOA and HMOA enhanced (p < 0.05) the final body weight and average daily gain in the grower and overall phases. An improved (p < 0.05) feed conversion ratio in the grower and overall phases was observed in broilers supplemented with LMOA. The breast and thigh muscles pH24h were higher (p < 0.05) in broilers fed with HMOA and the redness in thigh meat was also improved (p < 0.05). Additionally, supplementing LMOA increased (p < 0.05) the saturated fatty acids, unsaturated fatty acids and the ratio of polyunsaturated fatty acids to saturated fatty acids in breast meat. A positive effect occurred (p < 0.05) on jejunal villus height and ileal crypt depth in 21 d broilers supplemented with HMOA. Conclusion: Our findings indicated that dietary supplementation of MOA could improve the growth performance, meat quality, and fatty acids profile, as well as intestinal morphology. Furthermore, diets supplemented with mixed organic acids at 3000 mg/kg may be more desirable, considering the overall experimental results in broilers.

“…The previous study has demonstrated that dietary supplemented with mixed organic acid could improve performance ( 14 ), immune function ( 5 , 15 ), intestinal morphology as well as intestinal microbiota ( 10 , 16 ). Also, numerous scholars have illustrated the mechanism of MOA and summarized the benefits of MOA in livestock and poultry ( 4 , 17 ), especially in weaning pigs ( 7 , 8 ).…”

The purpose of this study was to explore the effect of dietary supplementation with mixed organic acids on intestinal health, enzyme activity, and antioxidative characteristics in broilers. A total of 192 1-day-old chicks were evenly allocated to three experimental groups with eight replicates, a basal diet with 0 (Control), 3,000 mg/kg (LMOA), 6,000 mg/kg (HMOA) mixed organic acid. The tissue and serum samples were gathered on 21 and 42 d of the experiment. An increased (P < 0.05) concentration of IgA, D-lactate (D-LA), and interleukin-10 (IL-10) in the serum of broilers diets with HMOA was observed. The levels of total antioxidant capacity (T-AOC) and catalase activity (CAT) in serum were enhanced (P < 0.05) with dietary and mixed organic acid, respectively, and increased (P < 0.05) content of superoxide dismutase (SOD) and CAT in the duodenum of broilers diets with LMOA was noticed. Also, LMOA decreased (P < 0.05) the pH value of the duodenum and enhanced (P < 0.05) the amylase activity of the pancreas, the tight junction protein (mainly Claudin-1, Claudin-2, and ZO-1) in the duodenum of broilers fed with mixed organic acid were promoted (P < 0.05), and the LMOA group performed better in the small intestine. In cecum microbiota, LMOA and HMOA modulated the structure of microbiota and mainly reduced the relative abundance of Escherichia coli. In brief, dietary supplemented mixed organic acid improved the health status of broilers by promoting the immune function, enhancing the antioxidative characteristics and tight junction proteins expression as well as cecum microbiota. However, LMOA groups may be a better fit considering the comprehensive effects of experiments and economic costs.

“…The use of OA salts (with sodium, potassium, or calcium) is the first solution, because it provides OAs in a solid form with a better smell [ 20 , 66 ]. Microencapsulation is another solution [ 67 , 68 ], because the undegradable film that envelopes the OA particles allows a more effective release of these substances. Thus, the beneficial action is promoted along the entire gut tract.…”

“…Similarly, diet palatability, weight gain or feed efficiency were not compromised, despite the tannin’s astringent action [ 67 ]. Instead, a blend of glycerol monolaurate (monoglyceride of lauric acid), curcumin and cinnamaldehyde (polyphenol compounds) was evaluated as feed additive for broiler diet, substituting conventional growth promoters [ 68 ]. Specially during the starter diet period, the authors found that the tested levels of inclusion (276 mg of curcuminoids/kg, 156 mg cinnamaldehyde/kg, 297 mg glycerol-monolaurate/kg) exerted a toxic effect on the animal, resulting in a growth reduction.…”

Polyphenols and Organic Acids as Alternatives to Antimicrobials in Poultry Rearing: A Review

et al. 2021

For decades antibiotics have been used in poultry rearing to support high levels of production. Nevertheless, several problems have arisen because of the misuse of antibiotics (i.e., antibiotic resistance, residues in animal products, environmental pollution). Thus, the European Union (EU) as well as the European Food Safety Authority (EFSA) promote action plans to diminish the use of antibiotics in animal production. Alternatives to antibiotics have been studied. Polyphenols (PPs) or organic acids (OAs) seem to be two accredited solutions. Phenolic compounds, such as phenols, flavonoids, and tannins exert their antimicrobial effect with specific mechanisms. In contrast, short chain fatty acids (SCFAs) and medium chain fatty acids (MCFAs), the OAs mainly used as antibiotics alternative, act on the pathogens depending on the pKa value. This review aims to collect the literature reporting the effects of these substances applied as antimicrobial molecules or growth promoter in poultry feeding (both for broilers and laying hens). Organic acids and PPs can be used individually or in blends, exploiting the properties of each component. Collected data highlighted that further research needs to focus on OAs in laying hens’ feeding and also determine the right combination in blends with PPs.
