“…This hypocholesterolemic and hypolipidemic effects resulted in consequent lower CRR, AC and AIP in broiler chicken. The hypocholeterolemic and hypolipidemic effects of prebiotics and probiotics have been reported earlier with higher HDL cholesterol (Yang et al 2019). The cardio-protective indices like CRR, AC and AIP recorded in this work may also be attributed to the enhanced absorption of micro and macronutrients, including antioxidants, which reduce…”

Significance and Impact of the Study: The use of antibiotic growth promoters in animal production and their consequent carry-over through meat and eggs as well emergence of antibiotic resistance and environmental pollution have become a global public health concern. However, to maintain the productivity and gut health of poultry alternatives to antibiotics is needed. This study establishes that a combination of Bifidobacterium bifidum and mannan-oligosaccharides is a superior alternative to antibiotics in poultry production which not only improves the growth and efficiency but also establishes a favourable gut microbial composition, body antioxidant defence system and lipid profile with better health indices in chicken.

“…It was proved that the usage of 0.05% B. subtilis culture in the diet had the greatest effect on the egg physical characteristics and the yolk weight, shell weight, Haugh unit and color all increased (P < 0.05) [41]. Similar results were obtained by [42]. However, in our study, except for the eggshell strength, yolk color, albumen height and Haugh unit in the second determination, there was no signi cant change in other indicators.…”

Background The excessive use of antibiotics in livestock feed industry caused inevitable side effect of microbial resistance. Beside this residual antibiotics in animal derived food stuff imposed serious health problems for humans. So this study aimed to investigate the potential use of Bacillus velezensis to substitute antibiotics for poultry production. A total of 468, 49-week-old Hy-Line Brown chickens, were randomly divided into four groups as control group (regular diet), experiment group I (0.1% B. veleznesis), experiment group II (0.2% B. veleznesis), and antibiotic group (50 mg/kg flavomycin), with three replicates per group and trial period consisted on 42 days.Results The results showed that, compared with control group, the average egg production rate and daily feed intake of experimental groups I and II increased significantly (P < 0.05), while the average egg weight was increased in experimental group II as compared to I. (P < 0.01). The feed conversion ratio was decreased (P > 0.05) in group II. Egg quality parameters such as yolk weight of the experiment group II was increased, but that of the antibiotic group and experiment group I was decreased, neither significant (P > 0.05). Moreover, the eggshell strength, yolk color, albumen height and Haugh unit were significantly increased (P < 0.05). Compared with the control group, probiotic groups can increase the progesterone and motilin (P > 0.05) but decrease the secretin and cholecystokinin in the blood plasma (P > 0.05).Conclusion This study suggested that B. velezensis can substitute in-feed-antibiotics and improved most of the study parameters significantly. Which suggested that B. velezensis has potential future application value to replace the feed antibiotics.

Similar results were obtained by [41]. However, in our study, at the second determination level, except for the eggshell strength, yolk color, albumen height, and haugh unit, there was no significant change in other indicators.…”
