INVESTIGATIONS ON THE DURATION OF ELIMINATION OF CERTAIN MEDICATIONS IN THE MILK OF COWS TREATED WITH MEDICATIONS

The highest frequency is on day 1 (after treatment) after which it gradually decreases. It should be noted that no antibiotic residues were detected in the collected milk samples prior to treatment. Antibiotic may of recently calved animals due intramammary treatments during dry period (chronic mastitis). If treatment less than 15 days until calving, detecting calving high. As noted, there two (10%) positive results, expiration waiting period, one treated and intramuscular fourth day, first period. somatic cell count sample from was 2850000 cells/ml 337000 animals. residue test influenced by components with mastitis. From analysis register, found intramuscularly cow received an overdose penicillin. This resulted a massive accumulation penicillin animal’s body resulting extension elimination more day.
