“…Lowering the caecal content pH by inulin has also been shown in other studies (Józefiak et al, 2008). Because FOS is not hydrolysed by enzymes in the small intestine of monogastrics, it reaches the colon intact.…”

This study was conducted to evaluate the effectiveness of inulin on the intestinal microflora, gut morphology, and performance of broiler chickens. After sex identification, 168 male Ross 308 broilers were randomly allotted to 3 treatment groups with 4 replicates and fed for 42 days. Experimental treatments including 0%, 0.5%, or 1% inulin were used. The experimental diets were formulated based on maize-soyabean meal. The results showed that livability and body weight gain were better for broilers fed diets supplemented with inulin, but livability did not vary significantly among groups and the control. Live body weight on d 42 was significantly increased when the diets were supplemented with 1% inulin. Feed intake and feed conversion ratio were not affected in birds fed diets with supplements in comparison with the control group. Inulin inclusion had no effect on Bifidobacteria, Lactobacilli and E. coli counts in ileal contents, but significantly increased Bifidobacteria counts and decreased E. coli counts in caecal contents. With the exception of significantly increased villus height in the ileum, the morphological measurements of the duodenum, jejunum, and ileum showed no response to dietary levels of inulin as compared with the control diet.In conclusion, the results from the current study suggest that feeding inulin may have a beneficial effect on intestinal microflora and morphology, and on the performance of broiler chickens.

“…We found, however, that this effect was apparent only for the 42-day period of feeding with 32 g · kg -1 WPC (1.88 g · kg -1 lactose). Similarly, Józefiak et al (2008) observed that the addition of 2 g · kg -1 lactose to the basal diet significantly decreased caecal pH in the sixth week of a chicken's life. The significant response to the WPC level providing 1.88 g · kg -1 lactose in terms of reduced pH of digesta from the whole small intestinal tract is most likely associated with fermentation in the ileum.…”

“…Inconsistent effects of adding different prebiotic carbohydrates, including lactose, on the upper intestinal tract pH, and bacterial populations, have been noted in poultry, however. Some previous reports demonstrated that ileum pH in chickens was not significantly affected by either low (0.2%) or high (4.5%) dietary lactose levels, with lower LAB counts (Józefiak et al, 2008) or with no effect on the counts of Escherichia coli, enterococci and lactobacilli (McReynolds et al, 2007). In contrast, Samli et al (2007) claimed that treatment with dried whey, in an amount equivalent to 28 g · kg -1 lactose, significantly increases the total number of LAB in the ileum of chickens.…”

“…Conflicting data exist, however, about the effects of dietary lactose on chicken growth performance. Recently, Józefiak et al (2008) demonstrated that 2 g · kg -1 diet of purified lactose significantly decreased the body weight gain of broilers grown to market age. In contrast, Douglas et al (2003) found that addition of 20 or 40 g lactose (pure form) resulted in numerical increases in weight gain of young chickens (1-20 days of age), whereas only the level of 60 g · kg -1 decreased their growth and feed efficiency, but caused more loose (watery) excreta.…”

ABSTRACT. The aim of this study was to investigate the effect of two levels of whey protein concentrate (WPC, 80.35% protein, 5.86% lactose) added to diets and duration of these treatments on growth and slaughter value, haematological parameters involved in immune processes, oxidative status of liver and breast muscle, and selected indices of gut function of broilers. A total of 560 Ross 308 broilers were randomly allocated into 7 groups with 10 replicates of 8 chickens per replicate. The experiment lasted 42 days and was divided into 3 successive feeding phases. The control group was fed basal diets consisted of maize, wheat and soyabean meal (C group). The other 6 groups received, for 7, 21 and 42 days basal diets with 8 or 32 g · kg -1 WPC added at the expense of soyabean meal (WL and WH groups, respectively). On day 42 group WH had a higher lymphocyte percentage (P < 0.05) compared to the control. The long-term (42 days) feeding with higher level of WPC significantly decreased the heterophile/lymphocyte ratio (P < 0.05 vs C). The number of erythrocytes on day 42 and the whole blood glucose on day 21 were significantly increased in WH birds than in controls. The concentration of serum total protein on both WPC levels was greater (P < 0.05) on day 21 compared with the C group. The reduction (P < 0.05) in liver thiobarbituric acid reactive substances (TBARS) and a tendency towards lower TBARS level in breast meat were observed in birds WH when fed for 42 days. Only higher dietary WPC amount provided for 42 days reduced the caecal and small intestinal pH values (P < 0.05 vs C). The ileal digestibility of crude protein was higher (P < 0.01) in birds fed with 32 g WPC during the first 21 days of life, compared to the C and WL treatments. The factorial ANOVA showed that on days 7, 21 and 42 the final body weight gain (BGW) and feed conversion ratio in broilers WL and WH were significantly better than in the C ones. Assessment of orthogonal contrasts revealed significantly higher (P < 0.05) final BWG in the WH broilers, compared to the WL dietary treatment; such effect was not observed in earlier feeding stages. Generally, carcass yield on both WPC dietary levels, and breast muscle percentage on WH treatment, were higher (P < 0.01 and P < 0.05, respectively) compare to the C group. In conclusion, WPC added to a conventional diets for growing chickens exerts a growth-promoting action and at a dose of 32 g · kg -1 may induce desirable changes in bird's health and the intestinal tract metabolism.

“…The third tested prebiotic, beta-glucan is well established in aquaculture, and treatment with 1% to 2% w/w feed allowed for significant improvement in FCR and increased BW in marine species (Kuhlwein et al, 2014). In poultry, addition of 0.025% modified beta-glucan did not improve broiler performance apart from increased BWG in starter period of rearing (Jozefiak et al, 2008). Whereas, the inclusion of laminarin and fucoidan beta-glucans as prebiotics improved growth parameters in weaned pigs .…”

In the post-antibiotics era, prebiotics are proposed as alternatives to antibiotic growth promoters in poultry production. The goal of this study was to compare in ovo method of prebiotic delivery with in-water supplementation and with both methods combined ( in ovo + in-water) in broiler chickens. Two trials were conducted. Trial 1 was carried out to optimize the doses of two prebiotics, DN (DiNovo ® , extract of beta-glucans) and BI (Bi 2 tos, trans-galactooligosaccharides), for in ovo delivery. The estimated parameters were hatchability and bacteriological status of the newly hatched chicks. Prebiotics were dissolved in 0.2 ml of physiological saline, at the doses: 0.18, 0.88, 3.5 and 7.0 mg/embryo; control group (C) was injected in ovo with 0.2 ml of physiological saline. Trial 2 was conducted to evaluate effects of different prebiotics (DN, BI and raffinose family oligosaccharides (RFO)) delivered in ovo, in-water and in a combined way ( in ovo + in-water) on broiler chickens performance. The results of the Trial 1 indicated that the optimal dose of DN and BI prebiotics delivered in ovo, that did not reduce chicks' hatchability, was 0.88 mg/embryo (DN) and 3.5 mg/embryo (BI). Both prebiotics numerically increased number of lactobacilli and bifidobacteria in chicken feces ( P > 0.05). In Trial 2, all prebiotics (DN, BI and RFO) significantly increased BW gain compared with the C group ( P < 0.05), especially during the first 21 days of life. However, feed intake and feed conversion ratio were increased upon prebiotics delivery irrespective of method used. Injection of prebiotics in ovo combined with in-water supplementation did not express synergistic effects on broilers performance compared with in ovo injection only. Taken together, those results confirm that single in ovo prebiotics injection into the chicken embryo can successfully replace prolonged in-water supplementation post hatching.
