Medicated feed. To feed medicated feed effectively, one must have sick birds and a definitive diagnosis. Then you or more likely your veterinarian can prescribe the appropriate medicated feed. FDA is moving in the direction of requiring all antibiotics be prescribed by a vet.
N Not all drugs are compatible with feed . For instance, heat labile drugs will be inactivated,especially if your feed is pelleted. In general, administering drugs in water is far more effective. Again, you must have a definitive diagnosis so as to administer the correct drug.
Second, do you plan to eat the birds or eggs they produce. If so, you must be sure the drug is cleared from the meat or eggs within the time frame you have in mind. This point is critical should you sell or donate the eggs or meat. Should anyone suffer an adverse reaction to drug residue in meat or eggs you have produced, you will probably face an enormous lawsuit.
Third, the poultry industry is moving away from growth-promoting antibiotics (medicated feed), organic meat and eggs are gaining in popularity (two companies now produce organic meat) and lastly, why incur un-necessary expenses?
