“…This could be better explained as a synergistic effect due to the combination of formic and lactic rather than an individual effect especially when lactic acid is concerned. In line with these findings, Partanen et al (2002) found that formic acid-sorbate blend had superior growth than that of formic acid addition in growing-finishing pigs. The improvement of growth performance might be related with the reduction of microbial populations in the stomach and small intestine when the acid mixture was added to the weaned pig diets.…”

요 약본 연구는 다양한 유기산제들의 급여가 이유자돈의 성장과 영양소 소화율에 미치는 영향을 비교하기 위하여 2번 의 사양실험을 수행하였다. 실험 1과 실험 2에서는 각각 이유자돈 180두 (4처리, 3반복, 15두/반복)를 공시하였다. 실 험 1은 기초사료에 formic acid, ammonium-formate, lactic acid 그리고 acid mixture를 각각 0.5%씩 첨가하여 총 5주간 사양실험을 실시하였으며, 실험 2는 formic acid, ammonium-formate, lactic acid 그리고 acid mixture를 각각 0.3%씩 첨 가하여 총 6주간 사양실험을 실시하였다. Acid mixture는 formic acid와 lactic acid가 50:50의 비율로 혼합된 제제를 사용하였다. 외관상 회장아미노산 소화율을 측정하기 위하여 각 처리별 3두, 총 12두를 공시하여 T-cannula를 회장 말단부에 부착시킨 후 적응기간을 거쳐 회장내용물을 채취하였다. 사양성적은 유기산 종류에 따른 개선 효과는 없 는 것으로 나타났으나 (실험 1), acid mixture 급여구에서 증체량이 lactic acid 급여구보다 높은 것으로 나타났다 (실험 2). 외관상 회장 아미노산 소화율은 lactic acid 급여구보다 acid mixture 급여구에서 개선되는 것으로 나타났다 (실험 1과 2). 실험 1과 2의 결과를 종합하였을 때 acid mixture (formic acid + lactic acid) 급여는 이유자돈의 사양성적과 외관상 회장 아미노산 소화율을 개선시키는 것으로 판단된다.

“…Limestone, sodium bicarbonate and trace-mineral premix exhibited very high buffering capacities compared with those of the single feedstuffs and attapulgite exhibited a high buffering capacity compared with the single feedstuffs while dicalcium phosphate showed lower buffering capacity. These findings suggest that the buffering capacity of poultry diets could be readily manipulated by varying the type and proportion of the inorganic mineral sources (Partanen et al, 2002). Such an approach might deserve further investigation as it could be a low-cost alternative to reduce the buffering capacity of feeds (Giannenas et al, 2014a;2014b).…”

Two experiments were conducted to study the effects of a blend of oregano essential oil (OEO) (as a source of natural antibacterial growth-promoting substances) and attapulgite (as a source of toxin-binder and as an antidiarrhoeal agent) on growth performance, intestinal microbiota, and intestinal morphometry in broiler chickens (Ross-308). In the first trial, the control group was fed a basal diet without antibiotic growth promoters, and the experimental group was fed the basal diet supplemented with 5% OEO (OEO) (Ecodiar ® powder at 150 g/tn) and 80% attapulgite 80% (Ultrafed ® at 6 kg/tn) blend. In the second trial, the experimental group was given the basal diet supplemented with 5% OEO (Ecodiar ® powder at 300 g/tn) and 80% attapulgite (Ultrafed ® at 3 kg/tn) blend. Intestinal microbiota was enumerated by conventional techniques with selective agar media at the end of the trial at both ileum and caecum, and intestinal morphology was assessed in the duodenum, jejunum and ileum. Results showed that in the first trial, despite the positive impact on daily gain and feed-to-gain ratio, growth performance was not affected by the blend with OEO and attapulgite. Furthermore, no effect was found on intestinal morphometry. However, the counts of lactic acid bacteria were increased significantly, and coliforms were decreased in caecal contents. In the second trial, a positive impact was noticed on daily gain and feed-to-gain ratio by the high OEO and low attapulgite blend. Dietary supplementation of OEO and attapulgite increased ileal villus height and lactic acid bacteria significantly and reduced coliforms in ileal and caecal contents compared with the control group. In conclusion, the combination of OEO at 15 mg/kg and attapulgite at 2.4 g/kg exerted a positive effect on growth performance, ileal villus height and intestinal microbiota of broilers. ______________________________________________________________________________________

“…The growth efficiency of market pigs was significantly increased by the addition of formic acid and this effect was further enhanced by the combination of formic acid with potassium sorbate (Partanen et al, 2002). Research implies an improved apparent ileal digestibility of protein and amino acids (Mroz et al, 1997) and an improved absorption of minerals (Jongbloed and Jongbloed, 1996).…”

Analysis of the effect of dietary protected organic acid blend on lactating sows and their piglets

-The objective of the present study was to evaluate the effects of blends of dietary protected organic acid supplementation on growth performance, nutrient digestibility, blood profiles, faecal microflora, and gas emission on sows and piglets with emphasis on their modes of action to improve pig performance. A total of 12 sows with an average initial body weight (BW) of 252.40±11.7 kg were used in this trial. Growth performance, blood profiles, and nutrient digestibility of sows and piglets fed protected organic acid were evaluated. The dietary treatments included a basal diet (CON); CON + 0.1% protected organic acid; and CON + 0.2% protected organic acid. The BW and back fat of sows was checked four days prior to farrowing and at the weaning day to calculate BW loss and back fat loss during that period. Inclusion of 0.2% protected organic acid provided a greater digestibility than CON diets throughout the experimental period in lactating sows. Dietary supplementation with 0.2% protected organic acid led to a higher white blood cell and lymphocyte concentration than CON treatment in sucking piglets. Immunoglobulin G concentration observed was greater in protected organic acid groups in lactating sow and sucking piglets. Increased faecal Lactobacillus counts with decreased E. coli concentrations were observed with the diets of protected organic acid fed to lactating sows. The E. coli counts were decreased in weaning piglets. The faecal H 2 S contents were decreased in 0.2% protected organic acid diets during farrowing on day 1. Dietary supplementation with protected organic acid blends beneficially affects the nutrient digestibility, ileal noxious gas (NH 3 and H 2 S) emission, as well as intestinal microbial balance in lactating sows.
