Evaluation of oxytetracycline hydrochloride (OTC) on non‐specific immunity, enzymatic profiles and tissue level retention in Labeo rohita (Hamilton, 1822) after administration through feed
ABSTRACT The present study was conducted to assess the effect of oxytetracycline hydrochloride (OTC) in rohu, Labeo rohita, with graded doses viz., 80 (1×), 240 (3×), 400 (5×) and 800 (10×) mg kg−1 fish biomass day−1 respectively through feed. Four hundred and fifty healthy rohu juveniles (20 ± 0.12...

Zusammenfassung: | ABSTRACT
The present study was conducted to assess the effect of oxytetracycline hydrochloride (OTC) in rohu, Labeo rohita, with graded doses viz., 80 (1×), 240 (3×), 400 (5×) and 800 (10×) mg kg−1 fish biomass day−1 respectively through feed. Four hundred and fifty healthy rohu juveniles (20 ± 0.12 g) were fed for 30 days followed by 10 days of withdrawal period. Each 10 days intervals, five fish were randomly sampled for blood, serum and tissue for estimation of growth, non‐specific immune parameters, enzymatic activities and retention of OTC in muscle tissue. The results showed that there was no significant difference (p > .05) on growth in the treated fish compared with the control. Respiratory burst activity, myeloperoxidase activity, bacterial haemagglutination and haemolysis activities were enhanced significantly (p |
