The Relationship Between The Stages Of The Sexual Cycle, The Pregnancy And Postpartum Periods And Vaginal Flora In Kangal Breed Bitches, Murat Findik, Ni̇l Maral, Oktay Keski̇n, Hakan Kalender, Jale Erdeğer, Seli̇m Aslan
Turkish Journal of Veterinary & Animal Sciences
This study was performed on females of the Kangal Breed (Turkish Anatolian Shepherd Dog) with the aim of determining the relationship between the stages of the sexual cycle and vaginal flora. The stages of the cycle in Kangal bitches (n= 16) were determined by performing vaginoscopic, vaginal cytologic and ultrasonographic checks at regular intervals and examining vaginal swab samples bacteriologically. The swab samples were inoculated onto 7% sheep blood agar and incubated for 18-24 h at 37 ºC and total counts of the resulting colonies were evaluated. In addition, inoculations were made onto 7% sheep blood agar, PPLO agar, Columbia …

Turkish Journal of Veterinary & Animal Sciences
We investigated the effect of hypothyroidism caused by thyroidectomy on the sexual cycle and pregnancy rates in rats. Twenty female rats were divided into two groups. The thyroid glands were totally extirpated in the first group (n = 10). An operation was performed but the thyroid glands were not extirpated in the second group (n = 10). In both groups, the differences in vaginal cytology were examined daily with vaginal irrigation, for 1 month starting 3 days after the operation. Preparations from the vaginal irrigation were stained with Giemsa. A male rat was placed in the cage containing the female …

Short Communication: Relationship Between Body Growth And Mammary Development In Dairy Heifers, L F. Silva, M J. Vandehaar, Brian K. Whitlock, R P. Radcliff, H A. Tucker
Brian K Whitlock, PhD, DVM, DACT
Our objective was to determine if prepubertal rate of body weight (BW) gain, independent of diet, was related to mammary development of dairy heifers. Data from two studies recently conducted at Michigan State University were used to identify factors, within a dietary treatment group, that would account for variation in first lactation milk production or amount of mammary parenchymal DNA at the time of puberty. Factors analyzed for variation in milk production during first lactation were: postpartum BW, prepubertal BW gain, gestational BW gain, postpartum BW gain, body condition score (BCS) at breeding, and BCS at calving. Factors analyzed for …

Serum Adenosine Deaminase Levels In Different Periods Of Pregnancy In Ewes, Muhammet Alan, Zahi̇t Tevfi̇k Ağaoğlu, Ahmet Uyar, Nuri̇ Altuğ
Serum Adenosine Deaminase Levels In Different Periods Of Pregnancy In Ewes, Muhammet Alan, Zahi̇t Tevfi̇k Ağaoğlu, Ahmet Uyar, Nuri̇ Altuğ
Turkish Journal of Veterinary & Animal Sciences
The levels of adenosine deaminase in different periods of pregnancy and after parturition were investigated in 13 ewes. Blood samples were collected on the day of mating and on days 10, 21, 35, 75, 104, 144 of pregnancy and on day 10 after parturition. Sera were harvested from these samples and adenosine deaminase levels were assayed as IU/L. Adenosine deaminase levels were high on the day of mating and after parturition but decreased during pregnancy. The lowest level was assayed just before parturition. Levels at the sampling times were 8.91, 8.30, 5.50, 3.96, 3.80, 2.18, 1.67 and 10.51 IU/L, respectively. …
Light And Electron Microscopic Examination Of The Single Kidney Of Unilateral Nephrectomized Rats During Pregnancy, H. Hamdi̇ Çeli̇k, Mustafa F. Sargon
Light And Electron Microscopic Examination Of The Single Kidney Of Unilateral Nephrectomized Rats During Pregnancy, H. Hamdi̇ Çeli̇k, Mustafa F. Sargon
Turkish Journal of Veterinary & Animal Sciences
The light microscopic and ultrastructural changes observed in the single kidney of pregnant rats were detected during mid-term pregnancy and after parturition and the results were compared with those of the pure nephrectomized group. The experimental studies were performed on 24 female virgin rats and all of them were subjected to unilateral nephrectomy. No pathology was observed in the light microscopic examination of the kidneys of the groups. In the transmission electron microscopic examination, in the pure nephrectomized group, cell swellings were present in the endothelial cells of the interlobular arteries and arterioles. Additionally, a mild cell swelling was seen …

The Relationship Between Ascorbic Acid, Oestradiol 17 \Beta And Progesterone In Plasma And Ovaries In Pregnant Holstein Cows, Seyfullah Hali̇loğlu, Behi̇ç Serpek, Nuri̇ Başpinar, Hüseyi̇n Erdem, Zafer Bulut
Turkish Journal of Veterinary & Animal Sciences
This study was performed to determine the relationship between the corpus luteum weight/diameter, follicular diameter and the levels of vitamin C, progesterone and oestradiol 17-\beta of the plasma, corpus luteum and follicular fluid of pregnant Holstein cows in a slaughterhouse. Progesterone and oestradiol 17-\beta concentrations were determined by the microtitration plate EIA method. Vitamin C levels were determined by spectrophotometer. Although there was a positive correlation between follicular fluid oestradiol 17-\beta levels and the follicle diameter in the follicular fluid, in contrast to oestradiol 17-\beta levels, small follicles have higher progesterone content than large follicles. This negative correlation was due …

Long-Term Administration Of Alcohol In Rats: Effects On Glucagon And Insulin Levels In Sera During Pre-Pregnancy, Pregnancy And Lactation Periods, Bi̇rsen Zeybek, Gülhan Türkmen
Turkish Journal of Veterinary & Animal Sciences
The effects of long-term administration of ethyl alcohol on insulin and glucagon hormone levels during pregnancy and lactation periods of rats were investigated. Female wistar albinos, 200±20 g, were used in this study. The control group consisted of 15 rats, and the experimental group consist of 25 ethyl-alcohol-addicted rats. While 0.9% saline (with sucrose) was to the control group, a 5 g kg perday dose of 20% ethyl alcohol was given to the experimental group. Blood samples were taken five times, during the pre-pregnancy (1), pregnancy (3), lactation (1) periods. Insulin and glucagon levels of sera were measured by RIA …

Erythrocyte, Saliva And Serum Arginase Activity With Serum Urea And Estrogen Levels Inakkaraman And Ivesi Sheep In Pregnancy And Postpartum, Sema Temi̇zer Ozan, Sema Yaralioğlu Gürgöze, Tülay İleri̇ Büyükoğlu, İhsan Hali̇feoğlu
Turkish Journal of Veterinary & Animal Sciences
Arginase (L-arginine amidino hydrolase E.C. 3.5.3.1) is an enzyme catalyzing the last stage of the Krebs-Henseleit cycle and, thus, converting arginine into urea and ornithine. Arginase also plays a part in protein and polyamine synthesis and is affected by hormones in terms of metabolic status. In the present study, erythrocyte, saliva, and serum arginase activity together with serum urea and estrogen levels were examined in Akkaraman and Ivesi sheep in pregnancy and postpartum. Comparisons were then made between the species. In pregnancy the urea level in saliva increased. However, the urea level in serum decreased. No clear difference was observed …

In this study 57 cows at the puerperal stage (between 15-45 days) and at early pregnancy period (between 8-58 days) were subjected to clinical and Ultrasonography check at 10-day intervals. On the 8 th day of post insemination (p.ins.) areas of nidation ranging from 0,5-1,5 cm were established by means of US (n=53) and on 40 animals (70,2%) the development of these areas were followed until the 58th day of pregnancy. In the other 13 cows (22,8%), begining from early embriyonic featal deaths (18) days and late embriyonic featal deaths (28 days) were established ultrasonographycally. 4 animals (7,0%) that no …
