“…Probiotics are a live microbial feed additive that beneficially affects the host animal by improving its intestinal bacterial balance (Fuller, 1989). Chickens fed dietary probiotics showed improved body weight gain (Torres-Rodriguez et al, 2005), reduced mortality (Vicente et al, 2007) and enhanced feed conversion, ultimately resulting in an increase of broiler production (Willis et al, 2007). Also, in this study, the SPB group showed a 2% higher body weight gain than the control.…”

Problem statement:As the intestinal function is intimately affected by fed diets, many kinds of natural substances and probiotics have been supplemented to broilers to raise poultry productivity due to activating intestinal function. Besides, the intestinal histology is clearly altered by intestinal functions. The aim of this study was to investigate whether Sugar Cane Extract (SCE) and commercial probiotic (SPB), either alone or in combination, could improve growth performance and how intestinal histological alterations would be observed in these birds. Approach: A total of 64, 7-dold male broiler chicks were randomly assigned to 4 treatment groups, consisting of 4 replicates of 4 birds each. Commercial mash starter and finisher diets were supplemented with 0.05% SCE, 0.4% SPB, or a mixture of 0.05% SCE and 0.4% SPB (SCE + SPB). Results: Body weight gain was better in all the experimental groups than the control. The greatest improvement was observed in the SCE + SPB group. Most values of villus height, villus area, cell area and cell mitosis in all intestinal segments were higher (p<0.05) in the experimental groups than in the control group. Most epithelial cells on the villus apical surface of the experimental groups were composed of protuberant cells. In addition, cell clusters composed of these cells were observed in the duodenum of the SCE + SPB group and in the jejunum of the SCE group. In the ileum, the SCE + SPB group had the most protuberant cells. Conclusion:The present results of enhanced light microscopic parameters and protuberant epithelial cells in SCE and SPB groups suggest that the intestinal villi and epithelial cells might be hypertrophied by SCE and SPB. The fact that a synergistic effect was observed with regard to growth performance and intestinal histology in the SCE + SPB group suggests that SCE is a good supplement to probiotics.

“…They concluded that under conditions of good hygiene, dietary supplementation with symbiotic had no beneficial consequences on quail performance. In contrast to our results, Torres-Rodriguez et al (2005) reported that dietary inclusion of a prebiotic (Fermacto) did not improve the weight gain of broilers fed with normal levels of dietary protein from 1 to 21 days of age, while it had beneficial effects on body weight gain of birds fed with LPD. Angel et al (2005) reported that feeding with diets containing medium and low levels of dietary nutrients (protein, calcium and available phosphorus) impaired broilers performance.…”

“…Angel et al (2005) found that broilers fed diets containing lower levels of nutrients (protein, calcium and available phosphorus) had poorer performance than the control group, but supplementation of those diets with probiotic, improved nutrients retention and thus prevented their negative effects. In another study, it was shown that supplementation with a prebiotic, improved the performance of broilers fed with LPD (Torres-Rodriguez et al, 2005). Considering the beneficial influences of probiotics and prebiotics on protein utilization and, the more efficiency of feed additives under suboptimal nutrition conditions (Torres-Rodriguez et al, 2005), it is expected that dietary inclusion of these additives reduce the negative effects of LPD.…”

KeywordsBroiler, low protein diet, prebiotic, probiotic.Submitted: June/2016 Approved: November/2016 ABStRACt A total of 360 one-day-old Cobb 500 chicks were randomly distributed in a completely randomized design according to a 3×2 factorial arrangement, consisting of three levels of dietary crude protein (100, 90 and 85% of NRCrecommended levels) and a feed additive (with or without feed additive). A blend of a commercial probiotic and a prebiotic were used as feed additives. Each treatment had four replicates of 15 birds each. Prebiotic and probiotic were added to the starter (days 1 to 21) and finisher (days 22 to 42) diets according to the manufacturer´s recommendations. The findings indicated that significant differences were not observed between 100 and 90% NRC for broiler performance (body weight, body weight gain, feed intake and feed conversion ratio) throughout the experiment, while the birds fed the diets containing 85% NRC had poorer performance than those fed 100% (p<0.05). Feed additives had no significant effect on broilers performance. There was no significant interaction between protein level and feed additive for performance. Dietary inclusion of feed additives had no significant effect on cecal lactobacillus and Escherichia coli counts at 21 days of age, while, at 42 days of age, feed additive increased lactobacillus and decreased the counts of Escherichia coli (p< 0.05). In conclusion, according to the findings of the current experiment, dietary crude protein could be reduced by 10%, without negative effect on broiler performance. Supplementation with feed additives had no significant effect on broiler performance, but beneficially influenced cecal bacteria counts at 42 days of age.

“…Dietary carvacrol reduced BWG, while FCR improved as compared to control or thymol fed birds. The result of other studies using prebiotics indicated improved BWG and FCR in broiler chickens (Rodriguez et al, 2005;Khaksar et al, 2008). Mean feed GTTs (minutes) were not influenced by fermacto and licorice extract concentration (P >0.05) at d 16 and 42, though the GTT of feed in diets containing the licorice extract was higher than in the control diets (P <0.054).…”

Six hundred Ross 308 male broiler chickens were used to study the effect of licorice extract and the prebiotic, fermacto, on performance, blood metabolites and gastro-intestinal transit time (GTT) of feed in the birds. The birds were fed according to a three phase feeding programme on a starter, grower and finisher diet during the ages of 1 -14 day, 15 -35 days and 35 -49 days of age, respectively. The basic diets during each phase contained either 100 or 95% of recommended digestible amino acid (RDAA) concentrations. The two basic starter diets were divided into five treatment diets: No supplement (control); and supplemented with 2.0 g fermacto/kg; and 2.0 (high); 1.0 (medium) and 0.5 (low) g licorice extract/kg diet. In the grower diets half the levels of these supplements were included, while the two finisher diets were fed without containing any of the experimental supplements. There was not a significant difference in body weight, feed intake and feed conversion ratio between the birds fed the control and the diets supplemented with the prebiotic or the different levels of licorice. However, birds receiving diets containing licorice extract had lighter abdominal fat pads compared to those fed the prebiotic or control diets. Blood cholesterol concentrations decreased significantly in birds receiving the high level of licorice in their starter and grower diets as compared to the control. The GTT of feed in the birds fed diets containing the prebiotic or licorice extract did not differ from that of the birds in the control. A 5% reduction in dietary RDAA concentration caused an increase in feed conversion ratio of chickens on the starter and grower diets and for the total duration of the experiment. ________________________________________________________________________________
