PHYTOBIOTICS AS AN ALTERNATIVE FEED ADDITIVE
2023
C. Valli | R. Kavitha
The identification and development of new and effective alternatives to antibiotics that do not hinder productivity assumes paramount importance in the context of antimicrobial resistance and food safety. In recent years, phytobiotics have been used as natural growth promoters in ruminants, poultry and swine, to improve growth and health. A wide variety of herbs, spices and essential oils have been used individually or as blends in poultry for their potential application as alternative growth promoters. In nursery and growing pigs supplemented with phytobiotics, intestinal pathogens were inhibited and beneficial microbial population that contributes to improving digestion and absorption of nutrients were increased resulting in increased weight gain and decrease in diarrheal syndrome. The inclusion of essential oils in the diet of finishing pigs, improved the productive yield and carcass characteristics. It also reduced the incidence of therapeutic treatment and mortality. Natural plant products have the potential to improve rumen fermentation, reduce loss of feed energy, improve animal health and productivity, increase animal lifetime performance, and reduce greenhouse gases production in ruminants. Phytobiotics with wide range of activities, is projected as a feed additive for higher market growth compared to other alternatives to antibiotics in the feed industry.
