“…The BWG results from this study are in agreement with the previous studies from Lan et al [ 33 ] Aluwong et al [ 34 ] Shahir et al [ 35 ], which demonstrated in chickens, both probiotics and prebiotics help to increase weight gain and reduce feed conversion ratio. Enhancement in growth performance and feed efficiency of broiler chickens which fed probiotics [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ] is a culmination of probiotic action like maintaining of beneficial microbial population [ 45 ], improving feed intake, digestion, [ 46 , 47 , 48 ] and altering bacterial metabolism [ 49 , 50 , 51 ].…”

Effects of Lactobacillus reuteri and Streptomyces coelicolor on Growth Performance of Broiler Chickens

There are well documented complications associated with the continuous use of antibiotics in the poultry industry. Over the past few decades, probiotics have emerged as viable alternatives to antibiotics; however, most of these candidate probiotic microorganisms have not been fully evaluated for their effectiveness as potential probiotics for poultry. Recent evaluation of a metagenome of broiler chickens in our laboratory revealed a prevalence of Lactobacillus reuteri (L. reuteri) and Actinobacteria class of bacteria in their gastrointestinal tract. In this study Lactobacillus reuteri and Streptomyces coelicolor (S. coelicolor) were selected as probiotic bacteria, encapsulated, and added into broiler feed at a concentration of 100 mg/kg of feed. In an 8-week study, 240 one day-old chicks were randomly assigned to four dietary treatments. Three dietary treatments contained two probiotic bacteria in three different proportions (L. reuteri and S. coelicolor individually at 100 ppm, and mixture of L. reuteri and S. coelicolor at 50 ppm each). The fourth treatment had no probiotic bacteria and it functioned as the control diet. L. reuteri and S. coelicolor were added to the feed by using wheat middlings as a carrier at a concentration of 100 ppm (100 mg/kg). Chickens fed diets containing L. reuteri and S. coelicolor mixture showed 2% improvement in body weight gain, 7% decrease in feed consumption, and 6–7% decrease in feed conversion ratios. This research suggests that L. reuteri and S. coelicolor have the potential to constitute probiotics in chickens combined or separately, depending on the desired selection of performance index.

“…Higher antibody titer against IBD might be the result of regulation of immunity by cytokines, which were secreted by immune cells by the stimulation of probiotics microbes ( Lammers et al., 2003 ). Shahir et al. (2014) who found that probiotic (5 × 10 10 colony forming units (cfu) gram S. cerevisiae ) improve the antibody responses to ND of broiler chickens.…”

Dietary effect of probiotics and prebiotics on broiler performance, carcass, and immunity

et al. 2020

This experiment was carried out to evaluate the effects of dietary addition of probiotics (Protexin) and prebiotics (active MOS, mannan oligosaccharides) on growth performance, carcasses, and antibody titer in broilers. A total number of 360-day-old Ross broiler chicks were randomly divided into 9 groups in a 3 × 3 factorial arrangement. Nine broiler starter (0–21 d) and finisher (21–35 d) diets were formulated by using 3 levels of probiotics (0, 1, and 2 g/kg of feed) and 3 levels of MOS (0, 1, and 1.5 g/kg of feed) and were randomly allotted to 9 groups. Feed intake was not affected by interaction of treatments during all phases ( P > 0.05). Feed intake was improved due to the main effect of probiotic ( P = 0.0001) or MOS ( P = 0.005). No interaction ( P > 0.05) was observed for weight gain in the starter, finisher, and overall phases. While, during the starter and finisher phases, weight gain was increased by probiotics ( P = 0.028 or 0.04, respectively). Dietary supplementation of MOS improved weight gain ( P = 0.01) and feed conversion ratio ( FCR ) ( P = 0.03) during the overall period, but during starter and finisher periods, weight gain and FCR were not affected by prebiotics. Apart from dressing percentage, no interaction or individual effect of probiotics and prebiotics was observed for carcass, breast, thigh, heart, liver, and gizzard weight. Antibody titer for infectious bursal disease ( IBD ) was improved ( P = 0.026) by the interaction effect between probiotics and prebiotics, when compared with the control group. Antibody titer against Newcastle disease ( ND ) was not affected by probiotics or prebiotics or their interactions ( P > 0.05). It could be concluded that supplementation of prebiotics or probiotics can improve the growth performance of broilers. It may also be helpful in improving the antibody titer against IBD in broilers fed antibiotic-free diets.

“…Not in agreement with our results, Yalçinkaya et al (2012) and Yalçin et al (2014) showed that serum AST and ALT were not affected by dietary supplementation of diets with mannanoligosaccharides that derived from the cell wall of yeast, and by dietary supplementation of yeast cell wall respectively. Houshmand et al (2012) found that mannanoligosaccharides were not able to influence the antibody response to Newcastle disease vaccination; moreover, Shahir et al (2014) have not found an effect of mannanoligosaccharides also on the antibody response to influenza vaccination. Sugiharto (2014) reviewed that prebiotics can enhance the immune response of chicken, but the mechanism of improving of the immune response by AO is not clear.…”

This study investigated the effect of different levels and consumption periods of Aspergillus oryzae meal on performance, carcass characteristics, blood variables, and immunity of broiler chickens. A total of 270 (male and female) Ross 308 chicks were randomly assigned to 9 treatment groups. Two levels (2 g/kg diet and 4 g/kg diet as-fed) of Aspergillus oryzae meal (AO) and 4 consumption periods of AO (starter, grower, finisher, and entire period) in a 2 × 4 factorial arrangement were used. Compared with control, AO used during the entire rearing period increased weight gain, reduced relative weight of abdominal fat, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) serum levels, and increased antibody titers against influenza and Newcastle disease vaccination and sheep red blood cells injection. Few differences in the variables considered were found if AO was added to broiler diets only during specific consumption periods, and between the two supplementation levels of AO. In conclusion, the addition of AO to the broiler diet can have beneficial effects in terms of performance, carcass composition, and health, but these positive effects were mainly reached adding AO for the entire rearing period.
