Raising healthy chickens is important to us, and we recognize that consumers want to better understand how their food is raised. Chicken is America’s favorite protein for a reason. For decades, the chicken industry has evolved its products to meet ever-changing consumer needs and preferences. Protecting our animals’ health and wellbeing is where we start. Without healthy chickens our members would not be in business. The use of antibiotics is one of many important tools in the treatment of human and animal disease. Preserving their effectiveness, both in humans and animals, is a responsibility we take seriously and work continuously with animal health companies, our farmers and our veterinarians to determine when an antibiotic is really needed.
We believe that providing a sustainable food supply will depend on our offering choices and a balanced approach to animal wellbeing. The amazing variety of chicken products today allows people to choose products that take into account many factors, including taste preference, personal values, affordability and chickens raised without antibiotics. We understand that consumers have questions and concerns about how and why antibiotics are used to treat and prevent disease in livestock and poultry. We hope this information will help to answer those questions and address some of those concerns.
Tetracyclines generally act as bacteriostatic antibiotics. Broad spectrum antibiotics with activity against Gram-positive and Gram-negative bacteria. Resistance is widespread. The tetracyclines are a closely related group of antibiotics with comparable pharmacological properties but different pharmacokinetic characteristics. Tetracyclines inhibit bacterial protein synthesis. Their site of action is the bacerial ribosome – 30 S subunit, thereby preventing binding to those ribosomes of aminoacyl transfer-RNA. Active transport of the drug into the bacterial cell must occur in order for the drug to be effective. Doxycycline enters the cell by passive diffusion.
Uses/benefits of Tetracycline For Chickens
Doxycycline is a second generation tetracycline mainly active against Gram-positive and Gram-negative aerobic and anaerobic bacteria. Doxycycline has low affinity for calcium and is relatively more stable in aqueous solution. It has a high relative liposolubility which readily compensates for the high protein binding. Doxycycline has several advanteges over other tetracycline analogues:
1. Absorption is almost complete 2. Tissue penetration is good 3. Elimination is slower
