But after the suggested prohibition on using antibiotics, products such as probiotics are getting substantial importance in nutrition because of their non-resistant and non-residual possessions. Basic aim of the chapter is to highlight fruitful effects of Bacillus Subtilis as non-antibiotic gut modulator and growth promoter in broiler chickens. Probiotics are the living culture of microorganisms. They flourish in the gut of the host and fortify the growth of valuable commensals in the digestive tract by minimizing the destruction triggered by pathogens, boost up the immune system, supporting the integrity of the gut mucosa and maintain a stability and balance of normal microflora. Probiotics can be used as best substitute to conventional antimicrobial therapy. In addition, it has been observed that probiotics plays a role in growth enhancement by augmenting useful enzymes in the body and promote the growth of other normal commensals such as Lactobacillus and having effect on gut luminal pH. Probiotics are quite active against intestinal pathogens in several ways, viz. including improved immune elimination, competing for mucosal attachment, striving for crucial nutrients, or producing antimicrobial complexes contrary to numerous enteropathogens. It can be concluded that B. Subtilis has the ability to modulate gut and immune system histophysiology and histomorphology and can be used as safe antimicrobial candidate in poultry nutrition. Knowledge of such possessions of the B. Subtilis as probiotics and the mechanisms of action may enable the researchers to manipulate the use of such alternatives for better growth production, and safe and healthy poultry industry.","PeriodicalId":444585,"journal":{"name":"Advanced Studies in the 21st Century Animal Nutrition","volume":"4169 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127563750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phytoadditives are feed additives originated from plants or botanicals that are used in poultry nutrition. This chapter provides an overview about the potency of alternative additive from plants as a basis for exploring it as a phytoadditive for poultry. These substances are derived from herbs, spices, and other plants and their extracts. They are natural, less toxic, residue free and ideal feed additives for poultry when compared to synthetic antibiotics. There efficacy of phytogenic applications in poultry nutrition depends on several factors, such as composition and feed inclusion level of phytogenic preparations, bird genetics, and overall diet composition. Addition of 100 mg/kg feed essential oils consist of carvacrol, thymol and limonene in matrix encapsulation improved performance and apparent ideal digestibility of nutrients of broiler chickens. Besides enhancing performance, phytogenic also has antioxidant, the effects of which are associated with essential oils (EOs) and their components. Administration of eucalyptus and peppermint oil blends by oral (0.25 ml/L drinking water) and spray route (0.1 ml/20 ml water) reduced Newcastle disease infection in broilers. Phytoadditives have antimicrobial, antifungal, antiviral, antitoxigenic, antiparasitic and insecticidal properties. The benefits of using phytoadditives in poultry nutrition are increased feed intake, stimulation of digestion, increased growth performance, reduced incidence of disease, improved reproductive parameters, feed efficiency, profitability. Based on the latest scientific findings presented in this chapter, the following main conclusions have been drawn that phytomolecule and that bioactives have potential to be developed as an alternative additive for poultry, and that promote health.","PeriodicalId":444585,"journal":{"name":"Advanced Studies in the 21st Century Animal Nutrition","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126174592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
