“…Some studies have shown limited or no benefit in terms of growth or carcass yield of supplying flavomycin (e.g. Haque et al 2010). In contrast to this study, including the same probiotic as used in the current study has been found to reduce growth rates (e.g.…”

Routine use of the antibiotic flavomycin in broiler production may lead to resistance, and alternative growth promoters are used to enhance performance. Two hundred day-old male Ross 308 broiler chicks were allocated to five dietary supplements included from d 1-42: flavomycin, three possible alternatives, a probiotic, prebiotic and a synbiotic, as well as a control treatment. There were four replicate cages of 10 birds each in each treatment. Compared with the control and antibiotics treatments, the probiotic, prebiotic and synbiotic treatments increased (p = 0.001) weight gain (64, 66, 73, 70 and 74 g/d, respectively). The synbiotic treatment reduced (p = 0.004) the feed conversion ratio, compared with the control and antibiotic treatments (1.70, 1.84, 1.83, respectively). Compared with the control and antibiotic treatments, the birds fed the synbiotic treatment had greater relative gizzard (+47%) and spleen weights (+115%), and lighter kidneys (-47%). The birds fed the symbiotic treatment also had thinner walls of the caudal gut segments. The prebiotic had the most beneficial effect on cecal microbiota, stimulating aerobic and lactic acid producing bacteria and reducing Escherichia coli bacteria. Enterococci were increased in the antibiotic treatment. We conclude that there were significant performance and health benefits of using prebiotics, probiotics and synbiotics for broilers, rather than antibiotics.

The effects of Flavomycin, Bacillus licheniformis and Enramycin on broiler performance, nutrient digestibility, gut morphology and the intestinal microflora were studied in a 42-d experiment. A total of 288, one-day-old, male, Arbor Acres broilers were randomly assigned to 1 of 4 dietary treatments with 12 pens per treatment and 6 birds per pen. The treatments were comprised of a control diet without supplementation, a diet supplemented with 5 ppm Flavomycin, a diet supplemented with the combination of 5 ppm Flavomycin and 1.35×10 9 CFU/kg Bacillus licheniformis, as well as a diet supplemented with 5 ppm Enramycin. The average daily gain (ADG) and feed conversion ratio (FCR) of birds fed the diet with Flavomycin combined with Bacillus licheniformis and the Enramycin diet were improved (P＜0.05) compared with the control diet. The digestibility of dry matter, energy, and calcium for birds fed the combination of Flavomycin and Bacillus licheniformis and the Enramycin diet were also enhanced compared with the control diet. All additives improved the villus height and crypt depth in the duodenum, jejunum and ileum on d 21. In addition, reduced numbers of cecal E. coli (P＜0.01) were found in birds fed all three supplemented diets on d 42. In conclusion, supplementation with Flavomycin and Bacillus licheniformis in combination or Enramycin would appear to be superior to supplementation with Flavomycin alone. All three supplemented diets were superior to the control.

“…Regardless of the inclusion levels of citric acid, half of the acid-supplemented groups reported significant increase in body weight gain (Chowdhury et al ., 2009;Haque et al ., 2010;Nourmohammadi et al ., 2010;Salgado-Tránsito et al ., 2011). However, only two experiments reported significant improvements in feed intake (Haque et al ., 2010;Nourmohammadi et al ., 2010) and feed efficiency (Chowdhury et al ., 2009;Salgado-Tránsito et al ., 2011). It is postulated that excessive amounts of dietary citric acid inclusion may compromise performance because two experiments using 60 g/kg citric acid in diets reported significant decreases in body weight gain.…”

SummaryThe objective was to summarize and describe the possible mode of action of dietary organic acids and their effects on growth performance of broiler chickens. Previous experiments have suggested that dietary organic acids decrease pH in diets and subsequently reduce pH in the proximal and distal intestine, increase nutrient utilization, and inhibit pathogenic bacterial growth in the gastrointestinal tract (GIT). The degree of pH reduction is usually greater in the upper part of the GIT (crop, proventriculus, and gizzard) than in the lower part of the GIT (duodenum, jejunum, ileum, and cecum). Bactericidal effects of dietary organic acids have been observed for pathogenic bacteria and even for beneficial bacteria to some extent. However, few significant results regarding bacterial modulation in the GIT have been reported. Dietary organic acids can improve dry matter and protein utilization in some experiments, but the extent of improvement in nutrient utilization is smaller than has been anticipated. Growth performance is likely improved, but results have been inconsistent due to variations in sources and inclusion levels of dietary organic acids. Differences in other dietary components and experimental environments among previous experiments likely contribute to the variable results. This review suggests that the effects of dietary organic acids on broiler chickens are not fully understood. Further experiments are required to reliably demonstrate the mode of action of dietary organic acids and their growth-promoting effects on broiler chickens. Keywords: acidifiers, gastrointestinal pH, growth performance, microbial population, nutrient utilization. ResumenEl objetivo fue resumir y describir el posible modo de acción de los ácidos orgánicos en la dieta y sus efectos sobre el crecimiento de los pollos de engorde. Experimentos previos sugieren que los ácidos orgánicos dietarios disminuyen el pH de la dieta y posteriormente reducen el pH en el intestino proximal y distal, aumentan la utilización de los nutrientes, e inhiben el crecimiento de bacterias patógenas en el tracto gastrointestinal (GIT). El grado de reducción del pH es generalmente mayor en la parte superior (buche, proventrículo y molleja) que en la parte inferior del GIT (duodeno, yeyuno, íleon y ciego). Se han observado efectos bactericidas de los ácidos orgánicos sobre bacterias patógenas e incluso sobre bacterias beneficiosas en cierta medida. Sin embargo, se han reportado algunos resultados significativos con respecto a la modulación bacteriana en el GIT. Los ácidos orgánicos en la dieta pueden mejorar la utilización de la materia seca y la proteína en algunos experimentos, pero el grado de mejora en la utilización de los nutrientes es más bajo que lo esperado. El crecimiento probablemente mejora, pero los resultados han sido inconsistentes debido a las variaciones en las fuentes y a los niveles de inclusión de los ácidos orgánicos en la dieta. Las diferencias en otros componentes de la dieta y entornos experimentales entre los ensayos anterio...
