“…The ability of synbiotics to improve the broiler performance is assumed to be induced by their influence on the sustenance of beneficial microbiota in the intestine, improving the digestion pathway and modifying the bacterial‐related metabolism (Awad et al, ). Also, synbiotic‐supplement maintains the populations of undesirable or possible pathogens at relatively depressed counts in the intestinal tract (Abdel‐Raheem, Abd‐Allah, & Hassanein, ). Moreover, the synbiotic dietary‐supplements increased the villus height and the proportion of villus height to crypt depth in the ileum (Ahmed, Hasan, Asaduzzaman, & Khatun, ).…”

The objective of the current research was to explore the possible impacts of dietary supplementation with synbiotic and/or organic acids (OA) on the performance traits, carcass yields and muscle amino acid and fatty acid (FA) profiles of broilers. Randomly, a total of 160 day‐old chicks (Ross 308) were assigned into four equal groups (40 birds each), with each group subdivided into eight replicates (five birds/pen). The control group (CON) fed the basal diet with no supplements, while diets of the treated groups were supplemented with OA (Sodium butyrate 40%; 1 g/kg), synbiotic (comprised Bacillus subtilis, Saccharomyces cerivisiae, Streptococcus faecium, Mannan‐Oligosaccharides and β‐Glucan; 1 g/kg) and equal mix of OA and synbiotic (2 g/kg). Broilers fed the diets supplemented with synbiotic or synbiotic plus OA produced a significantly higher feed utilization efficiency (p = 0.021) and carcass yields (p = 0.038) than the CON and OA‐supplemented groups. The group fed the diet supplemented with the synbiotic showed lowered serum cholesterol (p = 0.049), triglycerides (p = 0.001) and very low density lipoprotein (p = 0.032) when compared with the CON group. Regarding the polyunsaturated FA (PUFA) of breast muscles, synbiotic‐supplemented birds had significantly lower n‐6:n‐3 ratio (p = 0.047), however, a greater hypocholesterolaemic to hypercholesterolaemic FA (H/H) ratio was reported when compared with the CON group (p = 0.002). Among the essential amino acids, the contents of leucine and methionine in the breast (p = 0.032 and 0.007 respectively) and thigh (p = 0.023 and 0.003 respectively) muscles were greater in the synbiotic‐supplemented birds compared with the CON group. In conclusion, the synbiotic‐supplemented diet improved the PUFA:SFA, n‐6:n‐3 and H/H ratios by altering the FA composition of broiler muscles, which are important with regards to human health.

“…These findings are in line with the results of Samanya & Yamauchi (2002), who reported that B. subtilis led to an increase in villus height in the small intestine. Abdel-Raheem et al (2012) and Sen et al (2012) reported that dietary supplementations of B. subtilis increased villus length in comparison with the dietary control. In a later study, B. subtilis was found to increase the length and surface area of villi when compared with the positive control group under challenge by C. perfringens (Jayaraman et al, 2013).…”

The present study aimed at evaluating the effects of probiotics, prebiotics and their combination on intestinal histological changes in broiler chickens challenged with Clostridium perfringens. Two hundred and forty newly hatched male broilers (Ross 308) were equally distributed into six treatments: negative control group: unsupplemented unchallenged birds; positive control group: unsupplemented challenged birds; neoxyval-fed group: 0.5 g/kg diet (antibiotic) challenged birds; GalliPro-fed group: 0.6 g/kg diet (probiotic), challenged birds; TechnoMos-fed group: 0.75 g/kg diet (prebiotic), challenged birds; and synbiotic-fed group: birds challenged by C. Perfringens (4 x 10 8 CFU /mL). At 35 days old, samples from the ileum and jejunum were collected for histological measurements (height, width and villus surface area), and histopathological changes were assessed. The results showed that the length and surface area of villi in the ileum and jejunum were lower in the positive control, whereas length and surface area of villi in the ileum and jejunum of all feed additive treatments were higher, compared with the positive control and antibiotics. Necrotic enteritis (NE) development was evident in the positive control group. Signs of necrosis of the mucosal membranes, haemorrhage and fibrosis with depletions of gut associated lymph follicle (GALF) in submucosal layer were very clear. Pathological changes improved in all feed additives, except for the antibiotics. These results indicated that alternatives to antibiotics could be used to improve the length and surface area of a villus and the health of the animal by suppressing C. perfringens.

“…Contrary to our finding, Jung [110] and Erdogan [111] reported that the diet supplemented with synbiotic had no effect on feed intake, body weight, feed conversion efficiency and weight gain, of broilers. The final body weight, feed conversion efciency, weight gain were significantly higher in synbiotic supplemented broilers compared with the control group [97]. Body weight gain was increased significantly in birds' supplemented synbiotic compared with control and probiotic treated group [112].…”

Further, synbiotic reduced Escherichia coli and total coliform populations in the intestines of broiler chickens.…”

According to the increasing of human population in the world, it reached about seven billion people and it continuously increased. In this background, the food source in both animal and plant origin must be increased accordingly. For these we must use and add some feed additives such as antibiotic, probiotic, prebiotic, postbiotic and synbiotic for the animal feed to increase production (meat, egg, milk and fish) and improve health. In early cases, probiotic as mono or mixed beneficial live microorganism was used as feed additive that plays a significant role in several health conditions and performances. In another way, the scientists use some ingredients indigestible with carbohydrates origin, especially oligosaccharides as a source of energy for beneficial microorganisms in the body which were called prebiotic, and it is indigestible fermented food substrates that stimulate the growth, composition and activity of microorganisms in gastrointestinal and improve host. Most of the scientists urged to use all the above in such way that have more benefits in animal health and performance which were therefore called synbiotic, that was a combination between probiotic and prebiotic which beneficially had significant effects on the host by improving the survival and implantation of live microbial dietary supplements in the gastrointestinal tract, and thus improving animal health and performance. So, it was proposed that the synbiotic in this research increased beneficial microorganisms in the gastrointestinal tract and improved intestinal architect, and then promoted intestine environment. Consequently, it can improve blood indices, and especially decrease bad cholesterol (Low-density lipoprotein), decrease harmful microorganisms and toxins. However, it can also improve ingredient product, increase mineral absorption and nutrient. In conclusion, it can improve animal health and performance.
