Poultry Nutrition

Intestinal dysfunction of farm animals, such as intestinal inflammation and altered gut microbiota, is the critical problem affecting animal welfare, performance and farm profitability. China has prohibited the use of antibiotics to improve feed efficiency and growth performance for farm animals, including poultry, in 2020. With the advantages of maintaining gut homeostasis, enhancing digestion, and absorption and modulating gut microbiota, organic acids are regarded as promising antibiotic alternatives. Butyric and citric acids as presentative organic acids positively impact growth performance, welfare, and intestinal health of livestock mainly by reducing pathogenic bacteria and maintaining the gastrointestinal tract (GIT) pH. This review summarizes the discovery of butyric acid (BA), citric acid (CA) and their salt forms, molecular structure and properties, metabolism, biological functions and their applications in poultry nutrition. The research findings about BA, CA and their salts on rats, pigs and humans are also briefly reviewed. Therefore, this review will fill the knowledge gaps of the scientific community and may be of great interest for poultry nutritionists, researchers and feed manufacturers about these two weak organic acids and their effects on intestinal health and gut microbiota community, with the hope of providing safe, healthy and nutrient-rich poultry products to consumers.

Beneficial Effects

Intensive research has been directed to the potential of Natural Growth Promoters (NGPs) to replace antibiotics. Phytogenics and organic acids (OA) have been shown to be effective in reducing the incidence of gastrointestinal disorders, thereby improving growth performance in pigs (Steiner, 2006). The addition of OA to nonruminant diets is supposed to have beneficial effects on feed safety since OA have a detrimental impact on moulds and other feed contaminants. Moreover, due to a decrease in gastric pH, acidification of the diets creates favourable conditions for nutrient digestibility, especially in young piglets (Radcliffe et al., 1998). Dietary supplementation with essential oils originating from aromatic plants may directly affect the intestinal microflora, both in quantitative and qualitative terms. As shown under in vitro (Helander et al., 1998) and in vivo conditions (Kroismayr et al., 2005), oregano essential oils have strong antimicrobial properties. Finally, it has been confirmed that addition of fructooligosaccharides (FOS) to diets for nonruminants may stabilize the gut microflora by selectively supporting the growth of beneficial bacteria (Macfarlane et al., 2006). Depending on individual farm conditions, a well-adjusted combination of different strategies is supposed to maximize the efficacy of NGPs in antibiotic-free feeding systems. The aim of the trial was to investigate the effects of phytogenics and OA alone and in combination in comparison with a commercial diet containing no additives.

Targeted Release

An experiment was performed to evaluate the effect of four different microencapsulated blends of organic acids (OA) and nature-identical aromatic compounds (AC) on growth performance and gut health of broilers challenged with a recycled NE litter. A total of 600 one-day-old male Ross 308 broilers were randomly assigned to five treatments consisting of a basal diet (as negative control) supplemented with each of the tested microencapsulated blends: OA1 (malic and fumaric acid) + AC; 2.5 g/kg; OA2 (calcium butyrate+fumaric acid) + AC; 1.7 g/kg; MCFA (capric-caprylic; caproic and lauric acid) + AC; 2 g/kg; and MCFA + OA3 (calcium butyrate+fumaric and citric acid) + AC; 1.5 g/kg. The AC used was the same for all treatments; including cinnamaldehyde, carvacrol, and thymol (8:1:1), as major compounds. Three tested blends enhanced growth performance by improving intestinal histomorphology (p < 0.001). The tested blends enhanced the abundance of some beneficial families such as Ruminococcaceae and Lachnospiraceae; while reducing that of harmful ones such as Enterobacteriaceae and Helicobacteraceae. A further dose-response experiment showed that 0.5 g/kg of the blend 2 and 2 g/kg of the blend 4 improved growth performance and intestinal histomorphology of chickens on d 42 and decreased fecal Enterobacteriaceae and C. perfringens counts. Similar effects to the previous experiment were observed for cecum microbiota.
