Abstract This study was intended to assess the effect of graded replacements of corn gluten meal with Brewer’s yeast (Saccharomyces cerevisiae), with and without Bacillus megaterium supplementation, on performance, carcass characteristics, and the gut broilers microflora composition. A total of 720 mixed sex one-day-old broiler chicks (Ross 308) were randomly assigned to six dietary treatment groups (6 replicates each) in a 3 × 2 factorial arrangement, including 3 levels of Brewer’s yeast (BY; 0, 25, and 50%, to replace corn gluten meal; CGM) in the presence (+) or absence (−) of B. megaterium used as probiotic (Pro). The results showed that broilers fed diets containing BY up to 25% had comparable body weight (BWG), feed intake (FI), and feed conversion ratio (FCR) to the birds fed only CGM, over the entire feeding period (days 1–35). Conversely, higher levels of BY (50% replacing CGM) registered the lowest BWG values (P < 0.001) and impaired FCR (P < 0.010), but without effects on FI. The BY diets did not significantly affect the main broiler’s carcass traits. The diets with Pro did not involve modifications on carcass and organs size, but a tendency to increase the gizzard weight (P = 0.094) and to decrease SIL (P = 0.076) was observed. Pro addition also, reduced the cecal pH (P = 0.040) and diminish the total coliforms (P < 0.010), Clostridium spp. (P < 0.0001), and E. coli (P < 0.0001) count, whereas LAB, Bacillus spp., and Enterococcus spp. bacteria were increased (P = 0.022; P < 0.0001, and P < 0.0001, respectively).

Removal Of Metal Ions

The performance of the brewer’s yeast Saccharomyces cerevisiae to remove metal ions from four batch systems, namely Zn(II), Zn(II)-Sr(II)-Cu(II), Zn(II)-Ni(II)-Cu(II), and Zn(II)-Sr(II)-Cu(II)-Ba(II), and one real effluent was evaluated. Yeast biosorption capacity under different pH, temperature, initial zinc concentration, and contact time was investigated. The optimal pH for removal of metal ions present in the analyzed solution (Zn, Cu, Ni, Sr, and Ba) varied from 3.0 to 6.0. The biosorption process for zinc ions in all systems obeys Langmuir adsorption isotherm, and, in some cases, the Freundlich model was applicable as well. The kinetics of metal ions biosorption was described by pseudo-first-order, pseudo-second-order, and Elovich models. Thermodynamic calculations showed that metal biosorption was a spontaneous process. The two-stage sequential scheme of zinc ions removal from real effluent by the addition of different dosages of new sorbent allowed us to achieve a high efficiency of Zn(II) ions removal from the effluent. FTIR revealed that OH, C=C, C=O, C–H, C–N, and NH groups were the main biosorption sites for metal ions.

The aim of this study was to determine the effects of in ovo injection of Saccharomyces cerevisiae (SC) to fertile Ross 308 broiler eggs or dietary supplementation on growth performance, internal organ development, gut histomorphology and cecum microbiota during 14 d of growing period. This study was designed as 2×2 factorial experimental design. Fertile 92 Ross 308 eggs were injected with SC solution 0.2ml at 18d of hatch and 90 eggs non-injected as control, afterward dietary SC supplementation was applied during the 14 d to broiler diet. In this study, 160 broiler chicks were used in four treatment groups at 10 replicate for each treatment group and 4 chicks for each replicates. Treatment groups were A) in ovo SC injection + dietary SC supplementation, B) in ovo SC injection + basal diet, C) no injection + dietary SC supplementation, D) no injection + basal diet as control. Live weight, feed consumption, feed conversion ratio and gut histomorphology, caecum microbiota, internal organ weight were recorded at 14 days of age. Live weight gain increased in C group than in the D group. Feed consumption, feed conversion ratio and internal organ weights were not affected by the treatments. Villi length and villi width increased in A group among the other treatment groups in jejunum, villi length increased in A and C groups among the other groups in ileum. Villi length/villi width ratio increased in A group than in the D group in ileum, was not different in jejunum. LAB counts in caecum were higher in A group than those of C and D groups, but was not different from B group. Enterobactericaea count was lower in A and B group than in the D group, was not different from C group. To conclude, results showed that dietary Saccharomyces cerevisiae supplementation increased broiler growth at 14 day by increasing villi development and improving gut health.

Bread Production

The waste brewer's yeast S. cerevisiae (activated and non-activated) was compared with the commercial baker's yeast regarding the volume of developed gas in dough, volume and freshness stability of produced bread. The activation of waste brewer's yeast resulted in the increased volume of developed gas in dough by 100% compared to non-activated brewer's yeast, and the obtained bread is of more stable freshness compared to bread produced with baker's yeast. The activation of BY affects positively the quality of produced bread regarding bread volume. The volume of developed gas in dough prepared with the use of non-activated BY was not sufficient, therefore, it should not be used as fermentation agent, but only as an additive in bread production process for bread freshness preservation. Intense mixing of dough results in more compressible crumb 48 hrs after baking compared to high-speed mixing.

An experiment was conducted in the poultry rearing unit of Sahjalal Animal Nutrition Field Laboratory, Bangladesh Agricultural University, Mymensingh for a period of 30 days by using 108 one week aged straight run Starbro broiler chicks to find out the effect of vitamin E and selenium as feed supplement for the performance of broiler. Chicks were distributed into 4 dietary treatment groups each having three replications (R1, R2, R3) and each replication contains 9 chicks. Dietary treatment groups were T0 (Control i.e. without supplemental vitamin E and Selenium), T1 (Control + 50 mg vitamin E 0.11 mg selenium per kg diet), T2 (Control + 100 mg vitamin and 0.22 mg Selenium per kg diet and T3 (Control + 150 mg vitamin E and 0.33 mg Selenium per kg diet). At end of the feeding trail the body weight of birds were 1238.28, 1231.85, 1272.59, and 1218.33 gm/bird in treatment groups T0, T1, T2 and T3 respectively which differ significantly (p<0.05) where highest body weight observed in T2 group . Body weight gain was highest in T2 (control+100mg vitamin E and 0.22 mg Selenium per kg diet) and lowest in T0 (control). Total Feed consumption during the experimental period was 2480.30, 2523.80, 2564.56 and 2555.39 g for T0, T1, T2 and T3 respectively. At 2nd and 3rd week of age, weekly feed conversion ratio were significantly (p<0.05) higher in T2 group than the other groups including control. Meat yield parameter of broilers showed significant (P<0.05) differences in dressing weight, breast weight and shank weight. Based on the above findings, the result suggest that supplementation of Vitamin E 100 mg and 0.22 mg Selenium per kg diet from ‘‘Lolyvit-ES’’ as a source of Vitamin E and Selenium may be used in broiler rations.Asian J.
