Beta agonists are growth hormones used in cattle and swine production. When animals consume feed, they partition the extra energy into fat cells and when cattle and swine are given beta agonists, they partition the extra energy into muscle instead of fat. Beta agonists are a bronchodilator medicine that opens the airways by relaxing the muscles around the airways that may tighten during an asthma attack or in chronic obstructive pulmonary disease. Beta-agonists promote heavier, leaner carcasses, providing less expensive meat and healthier choices. The side effects of beta agonists include anxiety, tremor, palpitations or fast heart rate, and low blood potassium.
Screening tests for growth hormones are essential to prevent hormone residues transferring through to the food chain, Biorex Food Diagnostics deliver ELISA based kits for testing a range of growth promoters for various sample types.
