Live Therapeutics

Throughout a bird’s life, challenges occur that can disrupt the normal function in the intestinal tract. These challenges can include protozoal, bacterial, viral infections, and environmental stresses that can damage the delicate cells that line the intestines—disrupting the normal balance of flora that aid in digestion, processing of nutrients, and immune responses.

The intestinal tract of the bird is a complex system designed to take nutrients in the form of poultry feed and efficiently convert it to growth. The poultry industry is based on this simple concept of feed conversion—how efficiently broilers accomplish this task of reaching their growth potential. With the current shift in production strategies toward using little to no antibiotics, alternative products to replace antibiotics that promote a healthy intestinal balance are needed. A wide variety of these products are found on the market including various prebiotics, yeast extracts, phytochemicals, or essential acids. 

Probiotics in feed have been around for many years within the poultry industry, to support feed conversion and improve weight gain. A different type of probiotic has been developed which increases the average daily weight gain, improves food conversion ratio, and improves food safety from bacterial pathogens.1 These factors have a positive impact on the poultry industry while providing safe and healthy poultry for human consumption by reducing the pathogen load of Salmonella.

Complementing our leading poultry vaccines, Live Therapeutics includes probiotics to help you raise a healthy and cost-effective flock.

Probiotics and Live Therapeutics

A successful probiotic must have characteristics such as resistance to the acidic environment of the stomach and the bile salts of the small intestine and also the capacity to adhere to and colonize the intestine.3
