The Determination Of The Shelf Life And Some Nutritional Components Of Gilthead Seabream (Sparus Aurata L., 1758) After Cold And Hot Smoking, Şengül Bi̇lgi̇n, Mustafa Ünlüsayin, Levent İzci̇, Ali̇ Günlü
Turkish Journal of Veterinary & Animal Sciences
This study aimed to determine the shelf life, as well as chemical and microbiological quality of gilthead seabream (Sparus aurata L., 1758) prepared by 2 different methods of smoking (hot smoking and cold smoking). The effects of hot and cold smoking on the chemical composition and microbial load of gilthead seabream, as well as organoleptic analysis of the smoked product were investigated. Significant (P < 0.05) differences were found in the chemical composition of fresh and smoked seabream. The panelists liked the hot smoked fish more than the cold smoked fish, according to sensory analysis results. Changes in pH, thiobarbituric acid (TBA), and total volatile basic nitrogen (TVB-N) values were significant (P < 0.05) during storage at 4 °C. Microbiological analysis results demonstrated that the smoking techniques reduced the microbial content of the fish, whereas microbial content increased during storage. The smoking methods tested had a small effect on the level of vitamin D_3 in gilthead seabream.

Seasonal Variation Of Vitamin A And Beta-Carotene Levels In Ghezel Sheep, Gholamreza Afshari, A. Hasanpour, H. Haghpanah, Bahram Amoughli-Tabrizi
Turkish Journal of Veterinary & Animal Sciences
The present study was conducted to investigate the variations in blood serum and hepatic levels of vitamin A and b-carotene in Ghezel sheep throughout the year. From 1000 sheep aged 1-5 years, blood and liver samples were collected before and after slaughter. The levels of vitamin A and \beta-carotene in both samples were determined spectrophotometrically. The results showed significant differences between summer and winter values (P < 0.05), but no differences were found between the sexes (P > 0.05). There were significant correlations between the vitamin A levels in serum and the liver (P < 0.05). Due to low levels of vitamin A and \beta -carotene in Ghezel sheep during the winter, supplementary feeding of vitamin A is recommended during this season.
Apparent Nutrient Digestibility Of Balanced Diets With Soy Bean Extract Or Meat And Bone Meal In The Nile Tilapia (Oreochromis Niloticus L.) Infected With Vibrio Anguillarum, Kenan Engi̇n, Ferbal Özkan
Apparent Nutrient Digestibility Of Balanced Diets With Soy Bean Extract Or Meat And Bone Meal In The Nile Tilapia (Oreochromis Niloticus L.) Infected With Vibrio Anguillarum, Kenan Engi̇n, Ferbal Özkan
Turkish Journal of Veterinary & Animal Sciences
Nile tilapia, Oreochromis niloticus L., infected with Vibrio anguillarum or not infected were fed balanced diets containing vegetal (solvent extracted soy bean meal (SBM)) or animal (meat and bone meal (MBM)) protein sources in order to demonstrate the apparent nutrient and energy digestibility. Regardless of protein sources in the diets, feed intake was lower in the infected group. Apparent nutrient (AD_{DM} and AD_{CP}) and energy digestibility (AD_{kJ}) values of Nile tilapia fed the SBM diet were significantly better (P < 0.05) than those fed the CONT and MBM diets and changed little between the measurement days in both groups (non-infected and infected). Although no visible symptoms associated with vibriosis were evident on either the skin or internal organs, the significantly lower (P < 0.05) AD_{DM}, AD_{CP}, and AD_{kJ} values obtained between day 1 and 10 (specifically on days 3 and 10) in the infected group fed the CONT and MBM diets might have implicated the pathogenicity of the bacteria. Further research concentrating on higher amounts of solvent extracted soy bean and meat and bone meal, different environmental conditions and doses of infection with V. anguillarum and immune response parameters including physiological and cellular stress responses is needed in order to identify the overall apparent nutrient digestibility of plant and animal protein sources in Nile tilapia infected with V. anguillarum.

A total of 554 cattle from the Cappadocia region were divided into 5 different groups according to vaccination and were examined for Theileria annulata by microscope and indirect fluorescence antibody test (IFAT). The sampled cattle were checked for tick infestation. The prevalence of T. annulata was 60.5% by microscopic examination and 67.5% by IFAT. According to the microscopic examination, the prevalence of T. annulata was significantly (P < 0.001) higher in the unvaccinated group. The seropositivity according to IFAT was significantly (P < 0.001) lower in the unvaccinated group. The morbidity was significantly (P < 0.001) higher in the unvaccinated, semi-grazed, pure breed, and >2 years age groups. The mortality was significantly higher in the unvaccinated (P < 0.001), semi-grazed (P < 0.05), pure breed (P < 0.05), and female (P < 0.001) groups. A total of 1585 tick specimens belonging to the genera Hyalomma, Rhipicephalus, Dermacentor, Boophilus, and Ornithodorus were detected in 21.48% of examined cattle. The developing forms of T. annulata were determined in the H. anatolicum anatolicum ticks microscopically. Out of 554 cattle, 156 (27.61%) were diagnosed with acute tropical theileriosis. Out of these 156 cattle, 86 (56.21%) died due to the disease.

Effects Of Age, Sex, Feather Colour, Body Measurements, And Body Weight On Down And Feather Yield In Native Turkish Geese, Mustafa Saatci
Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to calculate the feather and down production by native Turkish geese and to investigate the effects on these traits. In total 145 native Turkish geese were used in the experiment. The birds were divided into 4 groups according to their feather colour at 10 and 12 weeks of ages. They were individually weighed and measured with the help of wing tags. Geese at 10 weeks had heavier feathers than those at 12 weeks, while geese at 12 weeks produced more down (P < 0.01). As detected in down weight, the older group has a greater amount of total feathers than the younger group (P < 0.001). Male geese produced significantly heavier feathers and down than females (P < 0.05). While black geese produced the heaviest feathers, yellow geese produced the heaviest down (P < 0.05). White geese generated the lightest weights of the products. The strongest correlation was found between total feather yield and chest girth (0.75). Reasonable correlations were detected between liveweight and other traits (0.36-0.62). This is not a widely studied subject in Turkey; therefore, the data obtained can be used for the identification of native Turkish geese.
