Development Of An Enzyme Immunoassay For The Determination Of Ovine Growth Hormone In Plasma, Behi̇ç Serpek, Seyfullah Hali̇loğlu
Development Of An Enzyme Immunoassay For The Determination Of Ovine Growth Hormone In Plasma, Behi̇ç Serpek, Seyfullah Hali̇loğlu
Turkish Journal of Veterinary & Animal Sciences
A competitive enzyme immunoassay for the determination of ovine growth hormone (oGH) was developed. The assay is based on (anti-rabbit IgG) goat IgG-coated microtitreplates, anti-oGH from rabbits, biotinyl-oGH and streptavidin-horseradish peroxidase. The assay is done directly with 40 ml of plasma and the calibration graph (90% relative binding at 0.38 ± 0.02 ng ml -1 and 50% relative binding at 3.80 ± 0.18 ng ml -1 ) is prepared in plasma without measurable endogenous oGH. Recovery in different plasma samples with added oGH amounted to 96.78 - 100.03 %, and all variabilities were < 10.44. The assay shows no significant binding of oFSH, oLH, oTSH and oPRL. The assay detects high and low plasma oGH levels within the physiological variation as well as changes in plasma oGH after stimulation with growth hormone releasing factor. Hence, it offers a reliable alternative radioimmunoassay. However, a reference method providing evidence of the identity of exogenous oGH will be required for proving illegal treatment with oGH and for forensic purposes.

Sensory Evaluation And Determination Of Some Physical And Chemical Characteristics Of Shrimp During Gold Storage, Candan Varlik, Taçnur Baygar, Özkan Özden, Nuray Erkan, Sühendan Mol
Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to determine the quality changes in shrimp stored at 4°C. In the study, whole shrimp samples were placed into straphore plates and stored in a refrigerator (+4°C). Each plate contained 250g samples. Every day the samples were analyzed for sensory properties, Total Volatile Basic Nitrogen (TVB-N) content, Trimethylamine Nitrogene (TMA-N) content, pH value and moisture content. According to findings of sensory, physical and chemical analyses the samples were found to be of "good quality" at day 0, "good quality," at day 1 and "spoiled" after 2 days.

Turkish Journal of Veterinary & Animal Sciences
This study was carried out in order to examine the effects of ProstaglandinF2a on uterine muscles in laying hens. 12 young, 18 adult and 10 old laying hens, in three groups (total 40) were used. Six different doses of PGF2a were injected into uterine tissue samples obtained from three groups using an isolated-organ bath. The response of the uterine muscles to PGF2a was recorded. For each dose the result was assessed as latent and amplitude values within each group and among the groups. In the young group, there were no significant responses in latent period or amplitude against various doses …

A Morphological Investigation Of The Postnatal Development Of The Syrinx In The Quail, Güner Bayram, Nari̇n Li̇man
Turkish Journal of Veterinary & Animal Sciences
The morphological and structural development of the syrinx was studied with a light microscope in 100 female and male Japanese quails from 1 to 60 days old and adults. The quails had a tracheobronchial syrinx since it was based on both tracheal and bronchial elements. Two tracheal syringeal cartilages were attached at both ends to the pessulus in the tympanum. In this species the tympanum had a slightly increased diameter. The pessulus was a wedge-shaped cartilage, its blade lying dorsoventrally so that it divided the airway vertically. The pessulus examined histologically at 35 and 42 days post-hatching showed marked and …

The calves used in the study were weaned at 5, 7 and 9 weeks of age, and the weights obtained at 6, 9, 12, 15 and 18 months of age were not significantly affected by the age of weaning. The weight gains determined between 6 and 18 months of ages with 3-month intervals were also not significantly affected by the different ages of weaning. The various ages of weaning did not result in a significant …

Cost Of Mastitis In Scottish Dairy Herds With Low And High Subclinical Mastitis Problems, Cengi̇z Yalçin
Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to estimate the cost of mastitis and the contribution of each cost component of mastitis to the total mastitis induced cost in herds with low and high levels of subclinical mastitis under Scottish field conditions. It was estimated that mastitis cost £140 per cow/year to the average Scottish dairy farmer in 1996. However, this figure was as low as £69 per cow/year in herds with lower levels of subclinical mastitis, and as high as £228 cow/year in herds with high sub- clinical mastitis. The magnitude and proportion of the cost components in the total …

The present study was carried out to determine the diurnal feeding patterns of broiler chickens given a choice between ascorbic acid (AA) supplemented and unsupplemented feeds under heated or unheated conditions. Broiler chickens were offered supplemented (with 200 mg AA/kg feed) and unsupplemented feeds, and the feeding behaviour for each feed was monitored by continuous recording of the weight of the feed container for 4 days under unheated (UH) and the next 4 days under heated (H) conditions. The weight and timing of each meal was used to calculate cumulative feed intake, AA intake, number of meals, mean meal size …

The Monthly Variations In The Blood Glucose Level Of Capoeta Capoeta Capoeta (G.Ldenstaedt, 1772) Living In Aras River, Seyi̇t Aydin, Ayhan Yildirim, Orhan Erdoğan
Turkish Journal of Veterinary & Animal Sciences
In this study, the monthly variation in the blood glucose level of Capoeta capoeta capoeta caught from Aras between August 1995 and June 1996 was determined. The average blood glucose level was determined to be 112.04±5.19 mg/dl in males and 106.32±9.68 mg/dl in females and 110.06±4.19 mg/dl in the population. The blood glucose level was highest (141.07±13.67 mg/dl) in April, and lowest (69.14±9.75 mg/dl) in September. It was deter- mined that the level of blood glucose was related to temperature and reproduction.

Lessepsian Fishes Spreading Along The Coasts Of The Mediterranean And The Southern Aegean Sea Of Turkey, Hati̇ce Torcu, Savaş Mater
Turkish Journal of Zoology
The taxonomy and biological characters of 22 Lessepsian fishes living on the coasts of the Eastern Mediterranean and Aegean Sea were examined and 8 species were determined to have commercial importance. Of these, Upeneus moluccensis and Saurida undosquamis have become economic fishes of the Eastern Mediterranean trawl fisheries, having significant stocks. The species previously misidentified as Upeneus asymmetricus was determined to be Upeneus pori. It has been pointed out that new species can be added to the recorded ones by the consequent influx of Red Sea biota into the Levant.

A Preliminary Study On The Reproduction Of The Rabbitfish (Siganus Rivulatus (Forsskal, 1775)) In The Northeastern Mediterranean, Hacer Yeldan, Dursun Avşar
Turkish Journal of Zoology
This study was carried out to identify some aspects of the reproductive cycle of the rabbitfish ( Siganus rivulatus) inhabiting the northeastern Mediterranean. For this reason, monthly sampling was conducted between February 1995 and June 1996, and a total of 473 specimens were used. By using the monthly changes in the values of the gonadosomatic index (GSI) and Condition Factor (K), it was found that their reproduction takes place during July and August. The mean diameter of ripe gonadal eggs was 0.44 mm; and mean fecundity and its standard deviation was found to be 434761±181006. Fecundity-total length, fecundity-total weight and …

Turkish Journal of Zoology
Toxicity of neem extract in comparison with DDVP (Dichlorvos) was determined against the housefly ( Musca domestica L). Neem leaf extract was applied at 5, 10, 20, 40 and 80 microgram/fly and DDVP was treated in 0.1, 0.2, 0.4, 0.8 and 1.6 microgram/fly doses. Lethal dose values were calculated with probit analysis and LD 50 and LD 90 values were found to be 8.4 and 169.8 ug/fly of neem extract respectively, whereas, values of 0.44 and 3.58 ug/fly of DDVP were found for LD 50 and LD 90 against house flies.
