“…Bacillus subtilis , as one of the three most common species of probiotic products used in the United States [ 37 , 45 ], has been widely used in functional feed supplements, such as in several dairy and non-dairy fermented foods, for improving human health and well-being [ 46 ]. Similarly, Bacillus subtilis has been used as a probiotic with multiple functions in poultry [ 141 ].…”

“…Generally, probiotics confer a health benefit to chickens due to their positive effects on microbiota composition (restoring microbial homeostasis), mucosal barrier integrity (reducing gut permeability), and immune response (reducing inflammation). Bacillus subtilis is one of the most common bacterial species used in commercial probiotic products for farm animal production [ 37 , 38 ], including in poultry [ 39 , 40 , 41 ].…”

Bacillus subtilis-Based Probiotic Improves Skeletal Health and Immunity in Broiler Chickens Exposed to Heat Stress

The elevation of ambient temperature beyond the thermoneutral zone leads to heat stress, which is a growing health and welfare issue for homeothermic animals aiming to maintain relatively constant reproducibility and survivability. Particularly, global warming over the past decades has resulted in more hot days with more intense, frequent, and long-lasting heat waves, resulting in a global surge in animals suffering from heat stress. Heat stress causes pathophysiological changes in animals, increasing stress sensitivity and immunosuppression, consequently leading to increased intestinal permeability (leaky gut) and related neuroinflammation. Probiotics, as well as prebiotics and synbiotics, have been used to prevent or reduce stress-induced negative effects on physiological and behavioral homeostasis in humans and various animals. The current data indicate dietary supplementation with a Bacillus subtilis-based probiotic has similar functions in poultry. This review highlights the recent findings on the effects of the probiotic Bacillus subtilis on skeletal health of broiler chickens exposed to heat stress. It provides insights to aid in the development of practical strategies for improving health and performance in poultry.

“…Most frequently used strains of Bifidobacterium include B. bifidum , B. breve , B. thermophilus and B. pseudolongum (Brashears et al , 2005). Even more extensive list in table form can be found in Joerger & Ganguly (2017). DFM preparations vary, with some containing a single strain of microorganisms and others containing multiple strains of bacteria (Brashears et al , 2005).…”

“…This broadly defined term includes a wide variety of organisms, including fungi, bacteria and cell fragments (Khan et al , 2016). The terms ‘direct‐fed microbial’ and ‘probiotic’ are often used interchangeably, even though they are not completely synonymous (McAllister et al , 2011; Joerger & Ganguly, 2017).…”

“…The mechanisms by which this is accomplished may include any or all of the following: effects on the immune system, interference with adhesion, competition for nutrients or production of inhibitory molecule. The CE with undefined cultures of porcine origin plus B. thetaiotaomicron was also tested on pigs (Joerger & Ganguly, 2017). The CE using defined cultures seems to be the method of choice as a preharvest intervention strategy against E. coli 0157:H7 in cattle (Swaggerty et al , 2018).…”

Safe, high-quality meat that is minimally processed, containing few added chemicals, is what is desired by the modern consumer. Biological approaches to meat safety appear more natural and, thus, are more readily acceptable. In this review, we examine biological approaches for meat safety and quality in the preharvest animal as well as during slaughter and in the post-harvest processing of the meat product. Biological components, including probiotics (Direct-Fed Microbials), vaccines, bacteriocins and lytic bacteriophage, are important components of a comprehensive approach to meat safety and quality.

We investigate recent advances in the Chemical Engineering aspects of food structuring agents and macronutrients: carbohydrates, proteins and lipids, and also the fate of food upon ingestion. Prebiotic effects on host-microbe interactions enable improved immune response and pathogen control. Formulation Engineering is an emerging area in the field of Chemical Engineering and requires detailed knowledge of the materials used, and the processes by which they are transformed / functionalised into products. Understanding 'comb-like' polymers and their interactions provide new structuring opportunities. Sustainable sourcing of alternative protein sources, natural lipid organelles and structuring of liquid oils are framed in a waste valorisation approach, utilising biotechnological approaches for new functionalities. Controlling natural and fabricated microstructures enable controlled digestion profiles. Author Comments:Apologies -I have now annotated the selected priority references. I have also attached a CORRECTED FINAL version of the manuscript
