“…Bolduan et al (1988) reported no effect of FoA supplementation on N-retention and OM and CP (both ileal and faecal) digestibilities (Table 2). However, Eckel et al (1992) reported that FoA supplementation increased the apparent faecal digestibilities of CP and GE by up to 4.4 and 2.5%, respectively (Table 2).…”

Supplementation of diets for weanling pigs with organic acids (e.g. citric, formic, fumaric and propionic acid) has been shown, in many cases, to increase average daily weight gain (ADG, range 4 to 27%) and gain to feed ratio (G/F, range 3 to 15%) and reduce the incidence of diarrhea. However, organic acid supplementation may not always improve ADG or G/F. Potential reasons for inconsistent results are briefly discussed. The growth promoting effects of organic acids may be attributed to increased nutrient and energy retention and digestibility (up to 4%), alteration of bacterial populations and metabolites in the gastrointestinal tract and(or) an effect on metabolism. More research on the physiological, microbial and biochemical effects of supplementing diets for weanling pigs with organic acids is necessary to provide better understanding of their mode of action.

“…For formic acid there is some evidence in the literature that it decreases pH and the population density of coliform bacteria in the gastrointestinal tract. Bolduan et al (1988) and Jensen (unpublished) have shown that formic acid reduces the pH in the stomach. Furthermore, Bolduan et al (1988), Kirchgessner et al (1992) and Jensen (unpublished) found that formic acid decreases the population of coliform bacteria in the stomach and small intestine of weaned piglets.…”

“…Similarly, the effect of propionic acid on the gastrointestinal ecosystem is also inconsistent. Cole et al (1968) reported that propionic acid reduced the population of coliform bacteria in the small intestine and Bolduan et al (1988) reported that it decreased the population of coliform bacteria in the stomach. However, Mathew et al (1991) and Sutton et al (1991) did not observe any effect of supplementation with propionic acid on coliform bacteria in the gut of weaned piglets.…”

The diverse collection of microorganisms colonising the healthy gastrointestinal tract of pigs, referred to as the microbiota, plays an essential role not only for the well-being of the animal, but also for animal nutrition and performance and for the quality of animal products. A number of naturally-occurring and artificial factors has been shown to affect the composition and activity of the microbiota in the gastrointestinal tract of pigs, these include: diet composition, growth promoting antibiotics, copper, use of probiotics, specific carbohydrates, organic acids and fermented feed.It is generally accepted that the microbiota in the small intestine competes with the host animal for easily digestible nutrients and at the same time produces toxic compounds. A pronounced microbial fermentation occurs in the stomach and small intestine in young piglets. Results have shown that approximately equal amounts of organic acids were produced in the three compartments: stomach, small intestine and large intestine. Further, experiments have shown that as much as 6% of the net energy in the pig diet could be lost due to microbial fermentation in the stomach and small intestine. On the other hand it has been shown that on a normal Danish pig diet, 16.4% of the total energy supply for the pig is achived from microbial fermentation in the large intestine. However, the microbiota in the gastrointestinal tract is unstable the first week after weaning and it takes 2 to 3 weeks after weaning before the fermentation capacity of the microbiota in the hindgut has developed.Use of growth promoting antibiotics in the feed is widespread in pig production. However, the use of the antibiotics avoparcin and virginiamycin as growth promoters in animal feed has been associated with an increase in resistance of bacteria to therapeutic agents and a fear that this could reduce the ability to treat diseased humans. This has caused an increased awareness of the use of antibiotics and a general wish to reduce the use of antibiotic growth promoters.Probiotics, organic acids and specific carbohydrates (yeast cell walls) are often suggested as alternatives to the use of antibiotic growth promoters. However, due to their relative high prices and the variability and unpredictability of their effect, the use of these products is financially questionable in practical pig production. One way to solve this problem may be the use of fermented liquid feed. Fermented liquid feed is characterised by a high number of lactic acid bacteria, high number of yeast and high concentration of lactic acid, and several investigations has shown fermented liquid 46 FEED ADDITIVES AND MICROBIAL ECOLOGY IN GUT feed to improve growth performance in pigs and to established a prophylactic barrier against gastrointestinal disorders. In general there is no doubt that the effect of feed additives are greatest in young animals where they have been found to improve growth performance and to reduce scouring and neonatal mortality. The present paper review our current state ...

R. 1995. The effect of formic acid and buffering capacity on the ileal digestibilities of amino acids and bacterial populations and metabolites in the small intestine of weanling pigs fld semipurified fish meal diets. Can. J. Anim. Sci. 75: 615423. An experiment was carried out to examine the effects of supplementa:tion of formic acid to semipurified diets containing fish meal for weanling pigs with low and high buffering capacity on nutrient digestion and bacterial populations and metabolites in the small intestine. Twelve barrows, weaned at 2l d, were fitted with a simple T-cannula at the distil ileum. The BW of the pigs at weaning and at the conclusion of the experiment were.7.8 and 13.8 kg, respectively. The pigs were fed four corn starch-based fish meal diets according to a two-period change-over design' The diets were fbrmulated to contain lSVo CP. For two of the diets, referred to as NCaP, fish meal was the calcium and phosphorus source. For the remaining two diets, referred to as HCaP, the levels of calcium and phosphorus were doubled (compared with the NCap diets) by the addition of calcium carbonate and dicalcium phosphate. The diets were supplemented with (+NCaP and +HCaP) or wit|out (-NCaP and -HCaP) l7o (wt|wt) formic acid. The buffering capacity of the HCaP diets increased (P < 0.05) when the levels of calcium and phosphorus were doubled. The pH of the diets were; 6.25, 4.46,6.13 and 4.59 for the -NCaP' +NCaP, -HCaP and +HCaP diets, respectively. Supplementation of formic acid to diets with low and high buffering capacity did not affect (P > 0.05) the apparent ileal digestibilities of AA. The pH, ammonia and VFA concenfiations, bacterial populations in ileal digesta and the inciderrce of diarrhea were also not affected (P > 0.05). Therefore, the supplementation of l7o (wt/wt) formic acid to corn starch-based fish meal diets with low and high buffering capacity for weanling pigs (7.8-13.8 kg) does not affect nutrient digestibilities and bacterial populations in the small intestine.
