Turkish Journal of Veterinary & Animal Sciences

Rainbow trout Oncorhynchus mykiss with an initial mean weight of 174 g (1+ year old) were fed on 3 different commercial diets (1 extruded pellet and 2 steam pellet) in the same environmental conditions until their first spawning. Changes in growth performance (weight gain, condition factor, specific growth rate and feed conversion rate), gonadosomatic index (GSI), hepatosomatic index (HSI) and body composition (protein, lipid, ash and dry matter) were investigated. The mean weight gain and condition factor for fish fed the extruded diet was significantly greater than for those fed the steam pellet diets (P < 0.05 ). There were no significant differences in specific growth rate, mean length increments and feed conversion rate among the groups, although the feed conversion rate for the extruded diet was slightly lower than the others. The HSI of the group fed an extruded diet was significantly greater than those of the others ( P < 0.05 ). The GSI values of female and male fish at the end of the study (October) did not differ significantly among the groups. Similarly, diet had no significant effects on the muscle composition of the trial fish, except that the muscle lipid of the group fed the extruded diet was significantly higher than those of the other groups (P < 0.05).

The Use Of Novobiocin And Cefixime-Tellurite In Broth, And Of Cefixime-Tellurite, Salicin, Rhamnose And Mug In Agar Medium For The Detection Of Escherichia Coli O157:H7 In Ground Beef, Murat Gülmez, Ethem Baz, Abamüslüm Güven Jan 2004

The Use Of Novobiocin And Cefixime-Tellurite In Broth, And Of Cefixime-Tellurite, Salicin, Rhamnose And Mug In Agar Medium For The Detection Of Escherichia Coli O157:H7 In Ground Beef, Murat Gülmez, Ethem Baz, Abamüslüm Güven

Turkish Journal of Veterinary & Animal Sciences

We aimed to improve the selectivity of lauryl tryptose (LST) broth and HC (hemorrhagic colitis Escherichia coli strains) agar for the detection of E. coli O157:H7 in frozen ground beef samples. The selectivity of LST broth was superior to that of LST containing novobiocin (20 mg/l) (LST + n), but LST containing novobiocin, cefixime (0.05 mg/l) and tellurite (2.5 mg/l) (LST + nct) was found to be unsuitable as an enrichment medium. The sorbitol positive strains were significantly more resistant to novobiocin than were the sorbitol negative strains (P < 0.05). As a result, the enrichment of ground beef samples in a selective broth without antibiotics such as LST, and then spread plating a subsequent amount from this original enrichment culture and the first three 10-fold serial dilutions onto a rhamnose and sorbitol based selective medium such as cefixime-tellurite HC medium (CTR-HC) was found to be recommendable as a routine cultural method. Transferring the metallic sheen property of eosin methylene blue (EMB) agar to CTR-HC agar can represent an alternative to the available media, and this will shorten the analysis time by 1 day.
