Using phytase prevents the build-up of phosphorus in the environment. Increase the animal's ability to digest the feed. Grains such as barley and oats contain sticky carbohydrates that make the cereals hard to digest. Beta-glucanase reduces this stickiness, allowing pigs and poultry to properly digest their feed. Microorganisms are naturally present in the digestive systems of animals.
Some microbes aid digestion, others can potentially cause disease.
Through biotechnology, scientists are trying to ensure animals have the healthiest possible digestive system. Prebiotics is the use of feed compounds to promote the growth of helpful bacteria in the intestine. Both prebiotics and probiotics reduce the strength of disease-causing bacteria. Hormones are chemicals secreted by the animal's glands. These chemicals act as switches, which start body processes.
