Effect Of Low Birthweight On Serum Thyroid Hormones, Glucose, Urea And Blood Ph In Newborn Lambs, Tufan Keçeci̇ Jan 2003

Effect Of Low Birthweight On Serum Thyroid Hormones, Glucose, Urea And Blood Ph In Newborn Lambs, Tufan Keçeci̇

Turkish Journal of Veterinary & Animal Sciences

In this study, serum thyroid hormone, glucose and urea levels as well as blood pH values were compared between six control (birthweight ? 2.5 kg) and seven experimental Merino lambs (birthweight < 2.5 kg, hypotrophic) at 2, 4, 8 and 24 h postpartum. Serum levels of total thyroxin (T_4), free thyroxin (FT_4), total triiodothyronine (T_3; with exception of 24 h postpartum), free triiodothyronine (FT_3; with the exception of 4, 8 and 24 h postpartum) and glucose were lower in hypotrophic lambs compared to the controls. However, the serum urea levels of hypotrophic animals were higher than those of the controls. On the other hand, serum T_3, FT_3 and FT_4 levels determined at 4 and 8 h were higher than those at 2 and 24 h postpartum in both groups. A similar case was also observed in the serum T_4 levels of hypotrophic lambs. In addition, the serum glucose levels of hypotrophic lambs were higher and the blood pH values of both groups were lower at 2 h postpartum. In conclusion, It was observed that low birthweight affected neonatal thyroid function, serum glucose and urea levels in lambs.

Optimisation Of Uv Treatment Duration To Induce Haploid Androgenesis In The Nile Tilapia (Oreochromis Niloticus L.), İsmi̇han Karayücel, Sedat Karayücel Jan 2003

Optimisation Of Uv Treatment Duration To Induce Haploid Androgenesis In The Nile Tilapia (Oreochromis Niloticus L.), İsmi̇han Karayücel, Sedat Karayücel

Turkish Journal of Veterinary & Animal Sciences

The optimum UV duration times of eggs were examined in order to develop a simple and safe method for inducing androgenetic development in the Nile tilapia, Oreochromis niloticus. The yield of androgenetic haploid O. niloticus to the pigmentation stage was 18.53 ± 5.3% (relative to controls) with an optimal UV irradiation dose of 540 Jm^{-2} (at 150 µWcm^{-2 }) for 6 min. Most embryos developing after fertilisation with normal spermatozoa showed abnormal morphology and a haploid number of chromosomes (n = 22). The success of oocyte denucleation was also assessed by using the recessive "blond" skin pigmentation character.

Estimation Of Breeding Values For Dairy Cattle Using Test-Day Milk Yields, İbrahi̇m Kaya, Yavuz Akbaş, Can Uzmay

Turkish Journal of Veterinary & Animal Sciences

The objectives of this study were to estimate genetic parameters and breeding values for test-day (TD) and 305-day milk yields, and to compare the results from TD and 305-day analyses. The data comprised 10,822 TD records from 1103 first lactations of Holstein cows from state farms in the western part of Turkey. Additive genetic, residual and permanent environmental variances, heritabilities and breeding values for 305-day and TD milk yields were estimated by the REML method using animal models. The heritability estimate (0.11) of TD milk yields was lower than the corresponding estimate (0.25) for 305-day milk yields. The product-moment correlations …

Immunohistochemical Detection Of Heparin-Binding Lectin In The Development Of The Bovine Thymus, Kami̇l Seyrek, Ayşegül Bi̇ldi̇k Jan 2003

Immunohistochemical Detection Of Heparin-Binding Lectin In The Development Of The Bovine Thymus, Kami̇l Seyrek, Ayşegül Bi̇ldi̇k

Turkish Journal of Veterinary & Animal Sciences

Heparin is a heterogeneous mixture of highly charged glycosaminoglycans that can exert a variety of biological and biochemical effects. Increasing attention is being paid to its role in cellular processes such as angiogenesis, cellular attachment, growth modulation and smooth muscle cell proliferation. The characterisation of cellular receptors for heparin-binding proteins is a rational step in the quest to elucidate the biochemical basis of specific binding and heparin-mediated responses. We studied the distribution of heparin-binding lectin at the optical level during bovine thymus development on sections of fixed tissue using antibodies raised against this lectin. The presence of ligands accessible to …

Turkish Journal of Veterinary & Animal Sciences

Sixteen dogs with suspected colitis and ulcerative colitis were examined by clinical, radiographic, laboratory and electrocardiographic means from a diagnostic perspective. In the history and clinical examination, mild diarrheic feces mixed with uncoagulated blood and mucus were determined in all dogs. Tenesmus after defecation, mild weight loss and anemia were common observations. Abdominal palpation revealed a palpable thickened large intestine. Biochemical analyses of blood serums showed that potassium levels were increased, and sodium and total protein levels were decreased. A contrast radiographic examination showed that colon walls were thickened; stenosis, dilatation and shortening of the colons had occurred; and the …

Milk Yield Characteristics Of Karakaş Sheep, Orhan Karaca, Nurhan Akyüz, Seval Andi̇ç, Tufan Altin

Turkish Journal of Veterinary & Animal Sciences

Milk yield and composition were determined in a total of 85 Karakaş ewes (Akkaraman breed). The data were collected from Yüzüncü Yıl University, Agriculture Faculty's Practice Farm and a rural farm near the University. Lactation length, average daily milk yield and total milk yield were 155.9 ± 4.3 days, 529.6 ± 31.6 ml and 84.7 ± 5.1 l, respectively. Milk fat, total solid and mineral percentages were 7.09 ± 0.25%, 19.75 ± 0.66% and 0.93 ± 0.03%, respectively. The differences between farms were significant (P < 0.05 and P < 0.01) for lactation length, average daily milk yield, total milk yield and milk fat percentage. The milk yields of ewes reared in rural farms were lower. In addition, the correlations between a number of characteristics were significant (P < 0.05 and P < 0.01).

Turkish Journal of Veterinary & Animal Sciences

The effect of L-carnitine supplement on the growth performance of Nile tilapia (Oreochromis niloticus) fingerlings was investigated. One group was fed normal commercial grow-out feed (the control group) while the other group was given feed containing 500 mg kg^{-1} L-carnitine. The addition of carnitine (the second group) had a positive effect on growth (7.9% higher than the control group). According to the final results, the carnitine-supplemented group had greater final weights (151.86 ± 27.19 g) than those of the control group (141.80 ± 24.83 g) (P < 0.05). This enhancement in growth was not due to a better feed conversion ratio (1.16 ± 0.31 vs. 1.20 ± 0.28) (P > 0.05). At the end of the feeding period of 90 days, 9.67% less feed …

Effect Of Using Urtica Dioica L. On The Quality Of Turkish Sucuk (Turkish Style Dry Sausage), Muhammet İrfan Aksu

Turkish Journal of Veterinary & Animal Sciences

Urtica dioica L. has become a very important plant, with beneficial effects on human health all over the world. In this study, the possibility of using U. dioica L. as an ingredient in Turkish sucuk was investigated. Turkish sucuk with U. dioica L. was evaluated in terms of its chemical, physical, and sensory attributes. The results showed that the level of U. dioica L. (0%, 1%, 3% and 5%) and ripening period (0, 3, 7, 10 and 14 days) had a significant effect on the moisture, pH, residual nitrite, L* and +a* values of sucuk (p < 0.01). +b* values were affected more by the ripening period (p < 0.01) than by the level of U. dioica L. (p < 0.05). Sensory evaluations showed that the addition of U. dioica L. to sucuk (cooked and uncooked) effected the sensory attributes compared with the control sucuk.

This study aimed to examine the effects of different packaging methods on some quality criteria of marinated fish. The heads and bones of the fish studied were removed and the fish were filleted. Then they were placed in brine for marination. After that, the samples were divided into two groups, packaged in jars with vegetable oil or vacuum packed in polyethylene bags and then stored at +4 ±1 °C. Sensory, pH and total volatile basic nitrogene (TVB-N) analyses were performed every 15 days during storage. At the end of 120 days marinated fish (anchovy, horse mackerel, chub mackerel and sardine) …

In this study, the egg production and hatchability characteristics of pheasants (Phasianus colchicus) mated in cages and as a free flock in closed pens were investigated. For this purpose 6 males and 30 females in a ratio of 1 male to 5 females were mated in cages and 4 males and 20 females were mated as a free flock in closed pens. The egg production (%), damaged egg rate, mortality rate, fertility, hatchability and hatchability of fertile eggs were determined as 32.84 and 19.38%, 28.63 and 36.34%, 26.67 and 30.00%, 61.09 and 47.27%, 49.55 and 29.46% and 54.36 and 41.54%, …
