“…However, it is not known whether these changes can either positively or negatively interact with the final digestion and/or absorption by the gut in birds given a xylanase-supplemented diet. In piglets, xylanase did not significantly affect the activities of BBM maltase and lactase (Li et al, 2004;Sileikiene et al, 2006) but increased the activity of γ-glutamyl transpeptidase in the jejunum mucosa (Li et al, 2004). In the present study, xylanase tended to increase the sucrase activity.…”

To study the working mechanisms for non-starch polysaccharidases to improve the growth performance of broiler chickens, a 21-day feeding trial was conducted. Two dietary treatments were included: 1) wheat diet (the control); 2) wheat+xylanase diet (xylanase, Allzyme PT, Alltech, Kentucky, USA). There were 8 replicates with 8 birds each for each treatment and the experimental diets were given to birds from hatch. Feed intake and body weight were measured on days 7 and 21. At the same ages, samples were taken for the determination of selected groups of luminal and mucosa-associated bacteria, mucosal morphology, brush-border membrane (BBM) bound enzyme activity and ileal nutrient digestibility. The xylanase supplement increased (p<0.05) body weight gain (BWG) and improved feed conversion ratio (FCR) at the end of the experiment but protein and starch digestibilities were not affected (p>0.05) by xylanase. Up to day 7, xylanase increased the counts of C. perfringens in the ileum and total anaerobic bacteria (TAB) in the caeca (p<0.05, p=0.07, respectively). By day 21, the counts of ileal lactobacilli (p<0.05) and TAB (p=0.07) were lower in birds given the xylanase-supplemented diet than in those on the control diet. No significant differences were observed in the counts of mucosaassociated lactobacilli and coliforms between xylanase treatment and the control at both ages. Villus height at the jejunum was not affected (p>0.05) by the supplement but crypt depth at the same site was reduced at day 7. Also, xylanase tended to increase the concentration of BBM protein (p = 0.09) and the specific activity of sucrase (p = 0.07) at day 21.

“…Digesta samples for the measurement of SCFA and lactic acid were pooled for each animal and period prior to analyses. For the measurement of enzyme activities, ileal digesta were collected 6 h post‐prandially (13:30 h on day 6), which is within the time range proposed for digesta collection for enzymatic measurements in ileal digesta of pigs (Ivan and Farrell, 1976, Sileikiene et al., 2006). Upon collection, the samples were immediately centrifuged (14 200 g ; 3 °C; 20 min), and the supernatants were collected into plastic tubes and stored at −80 °C.…”

In previous studies, dietary nucleotides have been shown to improve performance in single-stomached animals by promoting the renewal of small intestine epithelial cells and by influencing the activity and composition of the microbial community in the digestive tract. The present experiment was carried out with 12 barrows weaned at the age of 18 days and fitted with a simple T-cannula at the distal ileum. To determine short-term effects of dietary yeast nucleotides, the piglets received a grain-soybean meal-based basal diet with or without supplementation of 1 g/kg of a dried yeast product containing free nucleotides. Dietary supplementation with yeast did not affect bacterial numbers in the ileum as well as ileal concentrations of individual short-chain fatty acids (SCFA), total SCFA and total lactic acid (p > 0.05). Moreover, there was no effect of supplemental yeast nucleotides on ileal α-amylase, leucine amino peptidase, maltase and lactase activities (p > 0.05), as well as on ileal dry matter, crude protein and crude fibre digestibilities (p > 0.05). In conclusion, short-term supplementation with dietary yeast nucleotides did not affect microbial metabolite concentrations, bacterial numbers and enzyme activities in the ileal digesta as well as ileal nutrient digestibilities of newly weaned pigs.

“…However, ALP and LAP activity were indicated to be elevated following SYN inclusion within the digesta; whilst activity within their predominant site, the mucosa, appeared slightly reduced. Few reports exist but xylanase and phospholipase have been demonstrated to have no effect upon ileal LAP activity in pigs (Sileikiene et al, 2006).…”
