By having an idea of the value of this level of antibiotic, however, you can make a more accurate comparison of this feed with another. When purchasing additives in complete supplements or complete mixed feed, also have some idea of the value of other ingredients, particularly vitamins and minerals. Using average research results, producers can calculate approximate dollar advantages using antibiotics as growth promoters shown in this example of pigs 15 to 57 pounds. Summary Feed additives are effective and economical in improving performance and increasing profit in swine production. Antibiotic additives are recommended, particularly for creep, starter and growing rations.
Research indicates a response to antibiotics through the entire feeding.
Lower levels can be used in finishing rations to reduce cost. Research on antibiotic value in sow rations has not been conclusive. Antibiotics are particularly effective when sanitation is below normal and stress is above normal. Use only approved additives at levels recommended. Calculate actual antibiotic levels on an as-fed basis and compare cost.
