Effects of spray dried yeast (Saccharomyces cerevisiae) on growth performance and carcass characteristics, gut health, cecal microbiota profile and apparent ileal digestibility of protein, amino acids and energy in broilers

Abstract

The aim of present study was to determine the effects of supplementation of either synbiotic or probiotic on growth performance and carcass characteristics, gut health, cecal microbiota prolife and apparent ileal digestibility of protein, amino acids, and energy in broilers. Two hundred and forty-day-old straight-run broilers (Ross 308) were allotted randomly to 1 of 5 dietary treatments including basal diet (control), supplemented with either synbiotic (Nutromax P) or probiotic (Actera), each at 0.5 and 1 g/kg of the diet for 5 weeks. The overall findings of the study indicated better (p < 0.05) growth performance of broilers by synbiotic supplementation (1 g/kg) compared with those fed probiotic (1 g/kg) supplemented and control diets. The broilers consuming diet supplemented with 1 g/kg synbiotic has an increased carcass yield in comparison with those fed control diet. The findings of gut health indicated significantly increased villus height and goblet cells, by synbiotic supplementation (1 g/kg), compared with control diet in broilers. The broilers fed 1 g/kg synbiotic supplemented diets had 18% increased protein, 9 to 31% higher amino acid, and 34% better energy digestibility, whereas 8.4% decreased protein digestibility in broilers fed probiotic (1 g/kg) supplemented compared with control diet in broilers. The broilers fed synbiotic (1 g/kg) supplemented diets had increased cecal Lactobacillus and decreased Salmonella, E. coli, and Clostridium count compared with those fed control diet. In conclusion, synbiotic supplementation (1 g/kg) resulted in improved production performance, balanced cecal microbial composition, and better digestibility of nutrients in broilers compared with those fed control and diets supplemented with probiotics.

Effects of Saccharomyces cerevisiae hydrolysate on growth performance, immunity function, and intestinal health in broilers

“…However, it is not clear how SCH leads to the improvement of growth performance and modulates the body health in broilers. One hypothesis for the mechanism of action of SCH could be related to an improved intestinal resistance to external injuries or a possible role in the modulation of intestinal microbiota ( Khalid et al, 2021 ).…”

Combination of Gembili Tuber and Lactobacillus plantarum on the Performance, Carcass, Hematological Parameters, and Gut Microflora of Broiler Chickens

“…Synbiotics supplementation on the diet of broiler chicken were able to enhance the total of LAB and reduce the total of coliforms in the ileum and cecum (Setyaningrum et al, 2019). Khalid et al (2021), supplementation of probiotics and synbiotics significantly improved the amount of LAB and reduced the number of pathogenic bacteria. It was due to the colonization of pathogenic bacteria in the intestine can be inhibited.…”

The modulatory effect of encapsulated bioactives and probiotics on gut microbiota: improving health status through functional food

“…31 75 Supplementing the diet with probiotics will lead to an increase in the counts of probiotic microorganisms in the gut microbiota, as shown by several studies. [67][68][69][70][71] However, it is important to note that probiotics alone cannot modulate the production of microbial metabolites. 78 This finding led to the development of synbiotics, which are a mixture of probiotics and prebiotics whose synergic effect can benefit the gut microbiota, i.e.…”
