Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to isolate Edwardsiella ictaluri from diseased rainbow trout obtained from a commercial farm in the Ankara region, Turkey. Growth of the microorganism after 36 h of incubation was higher and purer at 28 ºC than at 37 ºC on all the organs (liver, spleen, kidney) of the 10 fish examined. Three groups, each consisting of 3 fish were used for experimental infection. All the fish in Group I, which received a pure culture suspension, died after treatment. There were no clinical symptoms of the disease or deaths in Group II treated with 1/50 concentration …

Turkish Journal of Veterinary & Animal Sciences
This study aimed to investigate whether the preovulatory LH surge mechanism is involved in sheep-to-sheep interaction for oestrous synchronisation. For that purpose, anoestrous ewes were inserted with intravaginal progestagen sponges for 13 days to induce ovulation. Upon sponge withdrawal, they were introduced either to 4 rams (n = 6, ram group), or to 4 ewes which were in follicular period (n = 6, follicular group), or 4 ewes which were in the luteal period (n = 6, luteal group) or else they were kept alone (n = 6, control group). The ewes were weighed and their body conditions were scored …

Turkish Journal of Veterinary & Animal Sciences
Inhibitory effects of some antibiotics on glucose 6-phosphate dehydrogenase from the erythrocytes of rainbow trout (Oncorhynchus mykiss Walbaum, 1792) were investigated. For this purpose, initially erythrocyte glucose 6-phosphate dehydrogenase was purified 1271.19-fold in a yield of 70.40% by using ammonium sulfate precipitation and 2',5'-ADP Sepharose 4B affinity gel. A constant temperature (+4 ºC) was maintained during the purification process. Enzyme activity was determined with the Beutler method by using a spectrophotometer at 340 nm. This method was utilized for all kinetic studies. Thiamphenicol, amikacin, gentamicin, and netilmicin were used as antibiotics. All the antibiotics exhibited inhibitory effects on the enzyme. …

Turkish Journal of Veterinary & Animal Sciences
The shelf life of fishballs prepared using raw and boiled fish was examined during cold storage (+4 ºC ± 1). Sensory, physical (loss of weight), chemical (TVB-N, TMA-N) and microbiological analyses (aerobic mesophilic bacteria, total psychrophilic bacteria) of fishballs made from raw and boiled anchovies and stored under cold storage conditions were carried out every 3 days. All analyses were carried out with two repetitions. The shelf life of fishballs was 9 days at +4 ºC ± 1 according to the results of the sensory, physical, chemical and microbiological analyses.

The Effects Of Urea And Molasses Addition Into Corn Harvested At Early-Milk Stage On Silage Quality And Digestible Dry Matter Yield, Ni̇hat Denek, Suphi̇ Deni̇z
The Effects Of Urea And Molasses Addition Into Corn Harvested At Early-Milk Stage On Silage Quality And Digestible Dry Matter Yield, Ni̇hat Denek, Suphi̇ Deni̇z
Turkish Journal of Veterinary & Animal Sciences
The objective of this study was to evaluate the effects of the addition of 0.5% urea or 0.5% urea plus 4% (w/w) molasses into corn varieties (Rx-947, 33-94, Frassino, and Arifiye) harvested at the early-milk stage on silage quality, in vitro digestibility and digestible dry matter (DM) yield. The addition of urea into silage increased the CP content (P < 0,05). The neutral detergent fiber and acid detergent fiber contents of the control silages were 69.40 and 38.68 for Rx-947, 69.34 and 38.69 for 33-94, 62.67 and 34.93 for Frassino, and 64.35 and 37.04 for Arifiye (P < 0,05). The addition of urea or urea plus molasses into silage increased the silage pH in all varieties, except for Rx-947 (P < 0,05). The lactic, acetic, propionic and butyric acid contents of the silage samples were between 23.2 and 153.3, 7.8 and 23.4, 0.6 and 1.6, and 0.0 and 0.54 g/kg DM, respectively. The addition of urea or urea and molasses into Rx-947 and Frassino varieties and the addition of urea only into the 33-94 variety increased silage lactic acid levels. The addition of urea and molasses into Rx-947, Frassino and Arifiye varieties also increased silage acetic acid levels (P < 0,05). There was a significant difference only between the Frassino and Arifiye varieties on this parameter (P < 0,05). The addition of urea only into silage decreased DM digestibility; the addition of molasses with urea, however, eliminated this negative effect of urea on digestibilit in all varieties, except for Frassino (P < 0,05). Digestible DM yields of untreated silage were 863.68, 1142.43, 1044.43, and 1075.07 kg/decare (10 decares = 1 hectare) for Rx-947, 33-94, Frassino and Arifiye, respectively (P < 0,05). The digestible DM yield of untreated Rx-947 silage was significantly lower than those of the others (P < 0,05). It can be concluded that corn varieties harvested at the early-milk stage (20% DM) can be ensiled, and that urea and molasses can be used as silage additive to increase CP and energy content of silages.

Turkish Journal of Veterinary & Animal Sciences
Chromosome numbers and structures were investigated in (Tinca tinca L., 1758) of the family Cyprinidae. A solution of 1 ml/100 g of 0.1% colchicine was injected intramuscularly. Four hours later the fish were killed and the kidney and gills were removed and cytogenetic methods were applied. Metaphase chromosomes of the cells in these tissues were investigated numerically and morphologically. It was determined that the fish have 2n = 48 diploid chromosomes made up of 6 pairs of metacentric, 8 pairs of subtelocentric and 10 pairs of acrocentric. The average haploid chromosome length was 2.191 µ. The chromosomes were named and …

Turkish Journal of Veterinary & Animal Sciences
Two fish species, Rutilus rutilus and Coregenus sp., were processed using 4 techniques, and the effects of the processing were investigated on the bactarial flora of fish products, which is a crucially important criterion with regard to fish spoilage. A total of 85 fish were processed using smoked, fried, marinated and salad techniques. The microbiological features of these processed fish products were examined. For this purpose, the total number of aerobic bacteria and numbers of Enterobacter, Pseudomonas, Staphylococcus, Lactobacillus, Enterococcus and Bacillus, which are called "normal flora", and fungi that are known to influence the spoilage of fish were determined. …

Thirty-four Streptococcus thermophilus strains were isolated from yogurt samples obtained from various villages in different regions of Turkey. These strains were examined for their antibiotic resistance patterns and plasmid carriage. The susceptibility of the isolates to 8 antibiotics (vancomycin, tetracycline, chloramphenicol, erythromycin, cephalothin, ampicillin-sulbactam, gentamicin and penicillin G) was determined by the disk diffusion method. Most strains of S. thermophilus were resistant to gentamicin (79%) and penicillin G (64%) and susceptible to chloramphenicol (94%) and tetracycline (88%). In plasmid DNA analyses, it was determined that 7 strains did not contain any plasmid DNA, while other strains included plasmid DNA ranging …

The objective of this study was to investigate ruminal fluid and whole blood oxidant-antioxidant status in normal and fauna-free small ruminants. Forty male Ramlıç lambs, a local breed in the Afyon area, with an average body weight of 32-36 kg and approximately 210 days old were used. The lambs were divided equally into 4 groups (faunated (F), defaunated (D), faunated + urea (FU) and defaunated + urea (DU)). Malondialdehyde (MDA) and glutathione (GSH) concentrations in the ruminal fluid and blood were measured. In comparison with the controls, all parameters were significantly higher in the fauna-free animals. The ruminal fluid MDA …
