Regional Impacts Of Alternative Price Policies For Turkey's Dairy Sector, Fahri̇ Yavuz, Si̇bel Tan, Carl R. Zulauf

Turkish Journal of Veterinary & Animal Sciences

Regional impacts of agricultural policies have emerged as a key concern in Turkey for both domestic reasons and because of Turkey's desire to join the European Union. This study uses a spatial equilibrium model to analyze the regional impacts of 2 alternative dairy support policies that are currently being considered: a price premium policy and a target price/deficiency payment policy. Both policies are found to exacerbate the post-1980 trend toward a greater share of milk produced in the more prosperous western regions of Turkey. Regional disparity in milk production increases more under the target price policy than under the price …

An Investigation Of Quality Changes In Anchovy (Engraulis Encrasicolus, L. 1758) Stored At Different Temperatures, Sevi̇m Köse, Mehmet Emi̇n Erdem

Turkish Journal of Veterinary & Animal Sciences

Quality changes in anchovy caught at different times during storage at ambient and refrigerated temperatures were investigated in 3 different batches. Sampling was carried out each day during storage. The results showed no significant differences among the anchovy batches except for bacteriological counts and trimethylamine (TMA) values at refrigerated temperatures. Storage time and temperature had a significant effect (P < 0.001, P < 0.05) on sensory, bacteriological and chemical values. Bacteriological counts and chemical values increased significantly (P < 0.05, P < 0.001) depending on time, while sensory results decreased (P < 0.05). According to sensory results, samples were acceptable for 1 day at ambient temperatures and for 2 days refrigerated. This study showed that refrigeration did not extend the shelf-life of fresh anchovies by more than a day compare to ambient temperature.

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. Use of salicine or 4-methylumbelliferyl-b-D glucuronide appears unnecessary in routine cultural techniques.

The Effect Of Gnrh Administration On Plasma Progesterone And Reproductive Performance In Ewes, Mehmet Aki̇f Çam, Mehmet Kuran, Erdoğan Selçuk

Turkish Journal of Veterinary & Animal Sciences

Two experiments were carried out to investigate the effect of GnRH administration at mating and on day 12 post-mating on the reproductive performance of Karayaka and Sakız x Karayaka (F_2) crossbred sheep. In the first experiment, ewes were allocated into a control group (K, n = 27), and groups administered 4 µg GnRH at mating (A, n = 27), on day 12 post-mating (AS, n = 30) and both at mating and on day 12 post-mating (AAS, n = 30). GnRH administration in the A and AS groups increased plasma progesterone concentrations (P < 0.01). The pregnancy rate at first mating in the AS group (86.7%) was higher than those in the ASS (66.7%), A (51.9%) and K (51.9%) groups (P < 0.01). There was no difference between the treatment groups in terms of litter sizes (1.31, 1.21, 1.21 and 1.20 for AS, K, A and ASS, respectively). In the second experiment, ewes were allocated into 2 groups, a control group (K, n = 70) and a group administered 4 µg GnRH on day 12 post-mating (AS, n = 73). The pregnancy rate at first mating was 71.4% and 80.8% (P > 0.05) and litter size was 1.24 and …
