This invention relates to the production of liquid synbiotics which are microbial-based health-providing supplements that contains probiotics and prebiotics in a synergistic blend for the avian and monogastric digestive systems, which include those of poultry and swine, respectively. The invention is novel in the Philippine setting because there are no synbiotics yet in the market that I have come across to date. The common product sold presently are probiotics that cater to gamefowls and not to a wide coverage, with good testimonials, for the monogastric digestive systems. It has been a common practice for many decades in the livestock industry to use sub-therapeutic doses of antibiotics in food-animal feeds and drinking water not only for the purpose of preventing animals from contracting diseases but also to improve their growth and breeding performances. Several studies however have shown that using antibiotics other than its intended purpose (i.e., to treat illnesses), have detrimental or bad effects in the long run on the health and safety of consumers and the environment. Instead of "preventing" illnesses, antibiotic-resistant bacteria have emerged and there are concerns that they are continuously increasing over time. There are already efforts to develop alternatives to AGPs(i.e, Antimicrobial Growth Promotants) and one of them is to use synbiotics.
