Fine Structure Of The Chloride Cell In The Gill Epithelium Of Brachydaniorerio(Cyprinidae, Teleostei), Sema Isisağ, Hatice Karakişi
Fine Structure Of The Chloride Cell In The Gill Epithelium Of Brachydaniorerio(Cyprinidae, Teleostei), Sema Isisağ, Hatice Karakişi
Turkish Journal of Veterinary & Animal Sciences
The main ultrastructural properties of the gill epithelium of the zebrafish, Brachydanio rerio are investigated. The pavement cells are distinguished with their microvilli, infolding protrusions and construction of an intercellular channel system, while the chloride cells sited in filamental and especially respiratory lamellar epithelia are characterized by a high number of well developed, large mitochondria and an expansive, membranous tubular system. The close relationship observed between these cell types indicates that, at least ultrastructurally, chloride cells are communicated with the external milieu via the channel system of the pavement cells.

Effects Of Selection For High Body Weight And Age Of Hen Onegg Characteristics In Japanese Quail (Coturnix Coturnix Japonica), Özge Altan, İsmail Oğuz, Yavuz Akbaş
Turkish Journal of Veterinary & Animal Sciences
The present study was conductud on qualis ( Coturnix coturnix japonica) to evaluate the effects of line and age of bird on egg characteristics. Total ninety Japanese quail from unselected (C) and selected (S) for high 4-week body weight for five generations were used. All birds were weighed individually at 10, 14 and 18-week of age and egg characteristics were obtained on all eggs collected during these weeks. The results showed that egg weight was increased by selection for high 4-week body weight and egg weight differences between the lines was due to increases in yolk and albumen weight of …

Fertilisation rate on average was 73.7% of total fencundity. 84.6% of the fertilised eggs was eyed and 96.0% of those eyed was hatched. Larvae reached free swimming stage after 23 days and survival rate was 98.9% of those hatched larvae. Larvae reached a mean weight of 305±56 mg at 40th …
The Mathematical Basis Of Inverse\Chi^2 And Inverse-Wishart Distribution Used In Animalbreeding Applications, M. Ziya Firat, Yüksel Bek
The Mathematical Basis Of Inverse\Chi^2 And Inverse-Wishart Distribution Used In Animalbreeding Applications, M. Ziya Firat, Yüksel Bek
Turkish Journal of Veterinary & Animal Sciences
The chi-square and Wishart distributions play an important role in animal breeding applications, especially in the estima-tion of variance components using Bayesian methods. These two distributions are so related that one can easily be derived from the other. In other words, the chi-square distribution is a particular case of the Wishart distribution or the Wishart distribution is a mul-tivariate generalization of the chi-square distribution. This article provides a simple mathematical basis of the above-mentioned dis-tributions; it shows how one is derived from the other and in what from they are used in animal breeding applications.

Estimation Of Individual Feed Consumption Of Fattening Lambs On Group Feeding, Ensar Başpinar, M. Muhip Özkan, Şafak Polatsü, İ. Yaman Yurtman, İ. Zafer Arik
Turkish Journal of Veterinary & Animal Sciences
The aim of the this study was to develop a model to estimate the individual feed consumption of fattening lambs which were fed in groups adlibitum. The individual feed consumption and live weight data obtained from the 3 previous works weresed. The feed consumption of 76 lambs in 41 different fattening periods were estimated by using the developed model and individual consumption values and group averages were compared with the estimated values. The model estimated the individual feed intake better than group averages in 33 of 41 calculations.

Hibernation And Body Weight In Dormice, Glis Glis Orientalis(Nehring, 1903) (Rodentia: Gliridae), Maintained Underuncontrolled Conditions, Ercüment Çolak, Nuri Yi̇ği̇t, Mustafa Sözen, Şakir Özkurt
Turkish Journal of Zoology
Hibernation pattern and changes in the body weight of juvenile and adult dormice, Glis glis orientalis, kept in uncontrolled conditions were investigated. It was determined that G.g.orientalis entered hibernation on October 28 when its body weight was 180 g and the ambient temperature was below 18 ºC, which seems to be the critical temperature for entering hibernation. Although body weight has an important role in entering hibernation at the beginning of the hibernation season, dormice hibernated as the hibernation season progressed regardless of their body weight. Adult dormice arose from hibernation during the period of May 13 to June 6. …

Early Development Of Barbel ( Barbus Barbus L.) Larvae, Metin Çalta
Turkish Journal of Zoology
In this study, the early development of barbel ( Barbus barbus L.) larvae has been determined by measuring their wet weight, dry weight, whole body mineral content (Ca, Mg, Na and K), skeletal development and gill development. It has been observed that wet weight, whole body mineral contents, the number of lamellae per filament of gill and the number of calcified vertebrae of larvae during early development stage increased by age, whereas dry weight decreased. The increase of whole body magnesium content has been very low compared with that of other minerals. In addition, a possitive relationship between whole body …

Physiological Energetics Of Buccinum Undatuml. (Gastropoda) Off Douglas,Isle Of Man (The Irish Sea), Ahmet E. Kideyş
Turkish Journal of Zoology
Physiological energetics of the common whelk ( Buccinum undatum) were studied in a population off Douglas, Isle of Man and an energy budget was constructed for the period February 1989 to January 1990. The components of the energy budget (in kJ m -2 year -1 ) for the population can be summarized thus: consumption (C)=753; growth production (P g )=34; reproductive production (P r )=4; mucus production=218; respiration (R)=96; ammonia excretion (U)=8; and faecal production (F)=393. Assimilation efficiency was 47.7%. P/B (annual production/biomass) was calculated as 1.40 representing an intermediate life span for this species.

Comparative Efficacy Of Bromadiolone, Cholecalciferol And Zinc Phosphideagainst Short -Tailed Mole Rat Nesokia Indica In Captivity, Amjad Pervez, Syed M. Ahmad, S. Waqar, A. Rizvi
Turkish Journal of Zoology
We conducted no-choice and paired choice feeding trials with individually caged Nesokia indica to evaluate the efficacy of Bromadiolone, Cholecalciferol and Zinc phosphide baits. Under no-choice test (1 day and 3 day) male rats consumed less bromadiolone bait. However, sex-wise difference was observed non-significant. Under choice feeding test, difference between bromadiolone bait intake and sex was observed non-significant. Under cholecalciferol bait, treated bait was consumed more than plain bait. Among the baits tested, cholecalciferol appeared promising for controlling short-tailed mole rat, Nesokia indica.

Turkish Journal of Zoology
Concentrations of cadmium, lead, copper, chromium and nickel were determined in the gill, liver and muscle of Cyprinus carpio, Barbus capito and Chondrostoma regium caught at 5 stations on the Seyhan river system. Heavy metal concentrations in the tissues tended to vary significantly among stations, and one station thought to be contaminated by hospital effluents showed particularly high metal concentration. Liver and gill tissues showed higher metal concentrations than muscle tissue. The ranges of mean metal concentrations (µg/g d.w.) were as follows: the range of cadmium concentration was 1.26-6.10, 0.96-4.72 and 0.51- 1.67, that of lead was 9.41-44.75, 5.22-37.15 and …
