The aim of the present study was to determine the influence of Cellgevity® on milt quality of Catfish, Clarias gariepinus extended in lactated ringers during chilled storage. Pooled milt from three bloodstocks were divided into three groups (T1, T2 andT3) each in triplicate. Milt were extended in lactated ringers and supplemented with Cellgevity® at 0mg (T1), 125mg (T2) and 250mg (T3). Milt were evaluated at days-0 (before storage) and days-1, 2, 3, 4 and 5 of chilled storage. Percentage mean spermatozoa motility was significantly (P < 0.001) lower in T2 and T3 than T1 from day-0 to 4. Percentage mean spermatozoa concentrationwas significantly (P < 0.01) lower in T2 than T1 from day-0 and significantly (P < 0.001) lower in T2 and T3 than T1 until day-3.Percentage mean live spermatozoa was significantly (P < 0.05) lower in T3 than T1 from day-0 and significantly (P < 0.001) lower in T2 and T3 than T1 until day-3. Percentage mean total abnormal sperm cells were lower in T2 and T3 than T1 from day-0 to 4 although significant (P< 0.05) only at day-0 and day-2.It was concluded that Cellgevity® (125 and 250 mg) resulted in a declined percentage mean spermatozoa motility, concentration, viability and total abnormalities. Hence, should not be supplemented in milt of catfish, Clarias gariepinus extended in lactated ringers in chilled storage.
