“…Other genera promoted in the birds with higher PU were Bacillus and Leuconostoc (Figure 1). Bacillus is considered as a probiotic in chickens; may improve bird performance [37]; exerts different enzymatic activities like amylase, xylanase, and pectinase [38]; and phosphatase activity can be expected from this genus, as previously reported in soils [39,40].…”

In this study, we aimed to investigate the ileum digesta of a large cohort of Japanese quail fed the same diet, with similar environmental conditions. We also address how P utilization (PU), Ca utilization (CaU), and bird performance (feed intake (FI), feed conversion (FC), and body weight gain (BWG)) modify intestinal microbiota of male and female quail. Despite the great number of samples analyzed (760), a core microbiome was composed of five bacteria. The Unc. Lactobacillus, Unc. Clostridaceae 1, Clostridium sensu stricto, Escherichia coli, and Streptococcus alactolyticus were detected in all samples and contributed to more than 70% of the total community. Depending on the bird predisposition for PU, CaU, FI, BWG, and FC, those species were present in higher or lower abundances. There was a significant gender effect on the ileal microbial community. While females had higher abundances of Lactobacillus, males were more colonized by Streptococcus alactolyticus. The entire cohort was highly colonized by Escherichia coli (8%–15%), an enteropathogenic bacteria. It remains unclear, if microbiota composition followed the mechanisms that caused different PU, CaU, FI, FC, and BWG or if the change in microbiota composition and function caused the differences in PU, CaU, and performance traits.

“…Such decrement might be due to action mode of bioactive additives inclusion which having a potential energy-sparing effect of ME containing diets as reported by Harrington et al (2015). Along the same line, Lee et al (2014) and Hmani et al (2017) reported that feed intake was statistically decreased with using B. subtilis in chicks diet compared with those unsupplemented. Also, Selim et al (2018) showed that enzymes supplementation (xylanase or Pectase or both of them) to broiler diets resulted in significant decrease in the amount of feed intake.…”

The experiment was performed to evaluate the impact of feeding different dietary programs having different levels of metabolizable energy (ME) during starter period and those of finisher ones which were less than that of the commercial standard (3150 kcal/kg) by 50, 100 and 150 kcal/kg with or without Bacillus amyloliquefaciens and energy enzymes on broilers productive performance and carcass characteristics. A total of 7300 Cobb 500 unsexed one day-old chicks were used. All chicks were fed pre-starter diet contained 23% crude protein (CP) and 2950 kcal ME /kg during the phase of (1-7) days. Afterward, experimental groups consist of 18 feeding programs where each program consists of two phases. During starter phase (8 -17) days, birds fed experimental diets contained constant level of CP (22%) with either of three ME levels (2950, 3000 or 3050 kcal/kg), whereas through the finisher phase (18 -35 days), birds received diets of constant level of CP (21%) with either of the three graded ME levels being 3100, 3050 or 3000 kcal/kg with or without studied additives for each. Results showed that the best live body weight, body weight gain and feed conversion ratio (FCR) were observed in dietary program included starter diet of 3050 kcal ME/kg and finisher one of 3100 kcal ME/kg with additives inclusion compared with the worst FCR of dietary program included starter diet of 2950 kcal ME/kg and finisher one of 3000 kcal ME/kg without additives. Carcass and abdominal fat weights were significantly improved (P≤0.05) by either feed programs with additives compared with those un-supplemented. Furthermore, and no significant effects on dressed and carcass cut weight were observed among dietary treatments. It can be concluded that, feeding dietary program included starter diet of 3050 kcal ME/kg with 22% CP and finisher one of 21% CP and 3100 kcal ME/kg (50 kcal/kg less than recommended) with bioactive additives had a beneficial effect on broiler productive performance and carcass yields.

“…Moreover, coarse particles increased the relative abundance of Ruminoclostridium1 , Lachnospira and Ruminococcus1 , and numerically increased families like Lactobacillaceae and Bacillaceae, suggesting a greater relative abundance of butyric, propionic, and acetic producers [ 41 , 42 , 43 ]. Some of these bacteria are related to a better performance in broilers [ 44 , 45 ]. Thus, it seems that an improvement in the development of proximal GIT due to feeding coarser particle pelleted diets promoted positive changes in the intestinal microbiome, with significant increases in nutrient digestibility and VFA production.…”

The objective of this study was to investigate the effects of particle size and xylanase supplementation in corn-based pellet diets on the performance and digestive traits in young broilers. A total of 512 male Ross 308 broilers were used in a 21-day study. The treatments were designed in a 4 × 2 factorial arrangement with four levels of geometric mean diameter (Dgw) of corn (540, 660, 1390, and 1700 µm), and two levels of xylanase (0 or 16,000 BXU/kg diet). Feeding coarse corn diets (1390 and 1700 µm Dgw) and xylanase supplementation showed an inferior coefficient of variation of body weight. Higher gizzard weight, microbiome alpha-diversity, and clustered separately beta-diversity (p < 0.05) were observed in birds fed coarse diets. The addition of xylanase promoted changes in relative bacteria abundance, increasing Lachnospiraceae, Defluviitaleaceae, Bacteroidaceae, Bacillaceae, Eggerthellaceae, and Streptococcaceae families in the 1700 µm group, and Christensenellaceae and Lachnospiraceae families in the 540 µm Dgw group. In conclusion, xylanase supplementation and particle size of corn interact in the intestinal environment, showing changes in microbial composition. Coarse diets and xylanase supplementation showed improved body weight homogeneity, which might be related to a better gut development and microbiota modulation.
