With increasing pressures to reduce or eliminate the use of antimicrobials for growth promotion purposes in production animals, there is a growing need to better understand the effects elicited by these agents in order to identify alternative approaches that might be used to maintain animal health. Antibiotic usage at subtherapeutic levels is postulated to confer a number of modulations in the microbes within the gut that ultimately result in growth promotion and reduced occurrence of disease. This study examined the effects of the coccidiostat monensin and the growth promoters virginiamycin and tylosin on the broiler chicken cecal microbiome and metagenome. Using a longitudinal design, cecal contents of commercial chickens were extracted and examined using 16S rRNA and total DNA shotgun metagenomic pyrosequencing. A number of genus-level enrichments and depletions were observed in response to monensin alone, or monensin in combination with virginiamycin or tylosin. Of note, monensin effects included depletions of Roseburia, Lactobacillus and Enterococcus, and enrichments in Coprococcus and Anaerofilum. The most notable effect observed in the monensin/virginiamycin and monensin/tylosin treatments, but not in the monensin-alone treatments, was enrichments in Escherichia coli. Analysis of the metagenomic dataset identified enrichments in transport system genes, type I fimbrial genes, and type IV conjugative secretion system genes. No significant differences were observed with regard to antimicrobial resistance gene counts. Overall, this study provides a more comprehensive glimpse of the chicken cecum microbial community, the modulations of this community in response to growth promoters, and targets for future efforts to mimic these effects using alternative approaches.

“…Numerous reports in pigs indicated that supplemental NSPases increased intestinal SCFA and this was associated with increased abundance and activity of specific bacteria communities such lactobacilli (96 -98) . In chickens, abundance of Enterobactreacea was reduced in caeca when birds were offered cereal-based diets with supplemental NSPases (99,100) . Furthermore, Choct et al (45,101) linked increased concentration of SCFA in the caecum of chickens fed diets with supplemental xylanase to increased flow of xylo-oligomers into the caecum.…”

The role of added feed enzymes in promoting gut health in swine and poultry

2013

The value of added feed enzymes (FE) in promoting growth and efficiency of nutrient utilisation is well recognised in single-stomached animal production. However, the effects of FE on the microbiome of the gastrointestinal tract (GIT) are largely unrecognised. A critical role in host nutrition, health, performance and quality of the products produced is played by the intestinal microbiota. FE can make an impact on GIT microbial ecology by reducing undigested substrates and anti-nutritive factors and producing oligosaccharides in situ from dietary NSP with potential prebiotic effects. Investigations with molecular microbiology techniques have demonstrated FE-mediated responses on energy utilisation in broiler chickens that were associated with certain clusters of GIT bacteria. Furthermore, investigations using specific enteric pathogen challenge models have demonstrated the efficacy of FE in modulating gut health. Because FE probably change the substrate characteristics along the GIT, subsequent microbiota responses will vary according to the populations present at the time of administration and their reaction to such changes. Therefore, the microbiota responses to FE administration, rather than being absolute, are a continuum or a population of responses. However, recognition that FE can make an impact on the gut microbiota and thus gut health will probably stimulate development of FE capable of modulating gut microbiota to the benefit of host health under specific production conditions. The present review brings to light opportunities and challenges for the role of major FE (carbohydrases and phytase) on the gut health of poultry and swine species with a specific focus on the impact on GIT microbiota.

“…These problems have been demonstrated to be attributable to the presence of non-starch polysaccharide (NSP) particularly ß-glucan (Abdulilah, 1995;Gracia, Latorre, Garcia, Lazaro, & Mateos, 2003;Józefiak et al, 2010). Inclusion of ß-glucans in the poultry diets create a viscous environment within the intestinal lumen, which can interfere with the activity of intestinal enzymes in the gastrointestinal tract and result in lower growth rate, poor feed utilization (Salarmoini, Campbell, Rossnagel, & Raboy, 2008), and higher sticky droppings (Sharifi, Barin, Yaghobfar, & Shariatmadari, 2007).…”

ABSTRACT. In this study, we have evaluated the effect of three multi-enzymes nutrient matrix values and compared the results with that fed barley and the corn diets without enzyme. In entire period, addition of all enzymes to the barley-based diet significantly (p < 0.05) increased feed intake (FI) and the highest intake was for birds that fed enzyme A (p < 0.05). Overall, from 0 to 42 days, average daily gain (ADG) was significantly (p < 0.05) increased by enzyme and birds fed enzyme A had the highest body weight (p < 0.05). Generally, from 0 to 42 d of age, feed conversion ratio (FCR) was significantly (p < 0.05) improved when enzyme added to barley-based diet, but there were no significant differences among diets containing enzymes A and C and the corn-based diet. The carcass weight, and the relative weight of the abdominal fat were significantly increased by enzyme, while small intestine and cecum decreased with enzyme addition (p < 0.05). Enzyme significantly decreased jejunal viscosity at Day 23 (p < 0.05), whereas pH of jejunal digesta was not changed (p > 0.05). Litter moisture and water to feed ratio at 15, 25, and 33 days of age significantly decreased by addition of all enzymes (p < 0.05). In conclusion, considering nutrient matrix values for all used enzymes improved performance of broilers and can be used in formulating diets commercial broiler diets based on barley.Keywords: carbohydrase, broiler, performance, nutrient matrix value.Efeito do uso de valores de tabela para enzimas degradadoras de PNA sobre o desempenho, ingestão de água, umidade da cama e viscosidade da digesta jejunal de frangos de corte alimentados com dieta à base de cevada RESUMO. Este estudo avaliou o efeito de três valores da matriz para nutriente multi-enzimático e comparou os resultados com os obtidos com dietas baseadas em cevada e milho sem enzima. Em todo o período, a adição de todas as enzimas à dieta à base de cevada aumentou significativamente (p < 0,05) a ingestão de ração, sendo a maior ingestão observada nas aves alimentadas com a enzima A (p < 0,05). No geral, de 0 a 42 dias, o ganho médio diário foi significativamente aumentado (p < 0,05) pelo uso de enzimas e as aves alimentadas com a enzima A apresentaram o maior peso corporal (p < 0,05). De modo geral, de 0 a 42 dias de idade, o índice de conversão alimentar foi significativamente maior (p < 0,05) com a adição de enzima à dieta a base de cevada, mas sem diferenças significativas entre as dietas contendo enzimas A e C e à dieta a base de milho. O peso da carcaça e o peso relativo da gordura abdominal foram significativamente aumentados pela enzima, enquanto o intestino delgado e o ceco diminuíram com a adição de enzima (p < 0,05). A adição de enzima reduziu significativamente a viscosidade do jejuno no dia 23 (p < 0,05), ao passo que o pH da digesta jejunal não foi alterado (p > 0,05). A umidade da cama e a razão água: ração aos 15, 25 e 33 dias de idade foram significativamente reduzidos pela adição de todas as enzimas (p < 0,05). Em conclusão, considerando os v...
