Skeletal muscle development in avian embryos depends on the activation, proliferation, differentiation, and fusion of embryonic myoblasts. These processes as well as early embryonic development are mainly regulated by major growth factors such as IGF-I, IGF-II, TGF-b and FGFs. In order to determine their differential expression, total RNA was isolated from whole embryos on each of the embryonal days (E) 0 to 6, from the thoracic/abdominal half of the embryo at E 7 and E 8, and from pectoralis muscle tissues at E 9 to E 20. Growth factor cDNAs were synthesized by reverse-transcription polymerase chain reaction (RT-PCR). All growth …

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.

The Effects Of Electrical Stimulation On The Sensory And Textural Quality Properties Of Mutton Carcasses, Mete Yanar, Hasan Yeti̇m
Turkish Journal of Veterinary & Animal Sciences
The objective of this research was to investigate the influence of electrical stimulation (ES) on the sensory and textural quality characteristics of mutton carcasses from elderly ewes. For this purpose, 14 ovine carcasses from 3-5-year-old ewes were subjected to ES with 350 V, and the effects of ES on the organoleptic and instron textural parameters were evaluated. The ES significantly (P < 0.01) improved the panel tenderness scores of the Longissimus dorsi (LD) muscle. Some of the Instron Warner Bratzler Shear parameters such as peak force and initial yield force values of the LD muscle were also highly significantly (P < 0.01) affected by ES, while the Semimembranosus (SM) muscle was not affected. Hardness and peak force 2 values of LD obtained from the Instron compression test were also significantly (P < 0.05) affected by ES. However, Instron compression parameters of SM muscles were not significantly influenced by ES treatment. The results revealed that the ES could considerably improve the tenderness of the LD from mutton carcasses. In conclusion, the application of ES to mutton carcasses from elderly ewes could be beneficial for the meat industry by increasing the merchandising value and quality of this sort of carcass.

Detection Of Listeria Monocytogenes In Faeces From Chickens, Sheep And Cattle In Elazığ Province, Hakan Kalender
Detection Of Listeria Monocytogenes In Faeces From Chickens, Sheep And Cattle In Elazığ Province, Hakan Kalender
Turkish Journal of Veterinary & Animal Sciences
Faecal samples collected from 206 chickens, 170 sheep and 130 cattle were investigated for the presence of Listeria monocytogenes in animals slaughtered at local abattoirs in Elazığ. The prevalance of L. monocytogenes was 4.36% in chickens, 0.58% in sheep and 1.53% in cattle. Of the 12 L. monocytogenes isolates, seven (58.33%) and five (41.66%) belonged to serotypes 1 and 4, respectively. Other species isolated were L. innocua, L. welshimeri, L. seeligeri, L. murrayi and L. grayi. These results indicate that animal faeces could be a source of contamination of carcasses with L. monocytogenes and may lead to foodborne listeriosis.

Behaviour And Biological Control Of Bacteriocin-Producing Leuconostocs Associated With Spoilage Of Vacuum-Packaged Sucuk, Özlem Osmanağaoğlu
Behaviour And Biological Control Of Bacteriocin-Producing Leuconostocs Associated With Spoilage Of Vacuum-Packaged Sucuk, Özlem Osmanağaoğlu
Turkish Journal of Veterinary & Animal Sciences
Non-motile, Gram-positive and catalase-negative anaerobic Leuconostoc sp. were found to be involved in the spoilage of vacuum-packaged refrigerated sucuk samples. The spoilage was associated with an accumulation of large quantities of foul-smelling gas and purge in the bag and loss of colour and texture in the meat. Many of these isolates produce bacteriocins, to which the predominant Gram-positive bacteria normally found in these products are sensitive. As the leuconostocs grew at low temperatures and produced bacteriocins, they inhibited the growth of associated sensitive bacteria. Attempts to inoculate purge from spoiled samples into fresh meat, vacuum packaging and refrigeration storage facilitated …

Glycobiology Current Molecular Biology, Sabi̇re Karaçali
Turkish Journal of Veterinary & Animal Sciences
Carbohydrate chemistry evolved into carbohydrate biochemistry and gradually into the biology of carbohydrates, or glycobiology, at the end of the last century. Glycobiology is the new research area of modern molecular biology, and it investigates the structure, biosynthesis and biological functions of glycans. The numbers, linkage types (\alpha or \beta), positions, binding points and functional group differences of monosaccharides create microheterogeneity. Thus, numerous glycoforms with precise structural differences occur. Each glycoform as a distinct biological ligand has a different function. Studies in glycobiology have concentrated on determining molecular structures and glycosylation mechanisms, investigating biological control mechanisms and the phenotypic characteristics …

Turkish Journal of Veterinary & Animal Sciences
In this study some blood parameters and the effects of age, sex, housing system and pregnancy of Tuj sheep that have been bred in the Kars region of Turkey were researched and compared. The various blood parameters including the amount of haemoglobin, haematocrit value, erythrocyte and leukocyte count, and the differential percentage of white blood cells were determined from blood taken intravenously. The haemoglobin and erythrocyte values were found to be significantly (p < 0.05) higher in 5-7-month-old Tuj sheep grazing in an open field than in 2-3-month-old male Tuj sheep feeding in a closed system. The erythrocyte count was found to be higher in 2-3-month-old female Tuj sheep in comparison to males. The haemoglobin, leukocyte and haematocrit values were also higher in this group of animals, though this was not statistically significant. The erythrocyte, leukocyte, haemoglobin, haematocrit values and differential percentage of white blood cells were not different in 5-7-month-old male and female Tuj sheep grazing in an open area. The erythrocyte number decreased after parturition in respect to the oestrus and pregnancy period. This decrease was statistically significant. The erythrocyte values were 10.2 x 10^6 /mm^3 before oestrus, 9.5 x 10^6 /mm3 during pregnancy and 8.2 x 10^6 /mm^3 after parturition. The haemoglobin value decreased significantly (p < 0.05) during pregnancy. The leukocyte number was found to be less during pregnancy in comparison to other periods; it was 7.7 ± 1.9 x 10^3 /mm^3 during pregnancy, 9.3 ± 1.9 x 10^3 /mm^3 before oestrus, and 9.7 ± 2.5 x 10^3 /mm^3 after parturation. The lymphocyte percentage increased significantly (p < 0.05) during the pregnancy period.

The aim of this study was to examine the effects of cadmium on oxytocin-induced myometrium contractions in rats, cows and cats in vitro. The frequency was 12.20 ± 1.2, 11.25 ± 2.7 and 10.70 ± 2.5/10 min, respectively, after 0.01 mM oxytocin induced with myometrial samples in rats, cows and cats. The peak amplitude was 3.84 ± 0.50, 3.44 ± 0.65 and 3.35 ± 0.45 g, respectively, after oxytocin induction. The frequency and peak amplitude decreased after the addition of 0.01 mM cadmium chloride (CdCl_2). The frequency was 1.2 ± 0.4 (p < 0.001), 2.5 ± 0.5 (p < 0.001) and 2.0 ± 0.6(p < 0.001), respectively, and the peak amplitude was 0.7 ± 0.3 (p < 0.001), 1.2 ± 0.2 (p < 0.001) and 0.8 ± 0.4 g (p < 0.001), respectively, in rat, cow and cat myometrium. Finally, the myometrium contractions were completely inhibited in the three species. In conclusion, the effects of cadmium may inhibit both calcium channels and the intracellular-induced mechanism.

In our study, malondialdehyde, antioxidant vitamins, antioxidant substances and some hematologic-biochemical parameter levels in nephrotoxicosis were investigated. Six dogs were used in the study. Blood samples taken before the experiment were used as the control. Blood samples were taken on days 2, 5, 7 and 10 during the experiment. During analysis, we found that the statistical changes were not significant in the retinol and Vitamin C levels of the experiment group when compared to those of the control group. \beta-carotene (P < 0.05) and Vitamin E (P < 0.001) levels were significantly decreased. Increases in the levels of malondialdehyde, seruloplasmin and urine \gamma-glutamyl transferase (GGT) enzyme were P < 0.001, while decreases in the amounts of glutathione were P < 0.001. We also found that changes in erythrocyte and hemotocrit levels were not significant. On the other hand, increases in the levels of leucocyte (P < 0.01), creatinin and blood urea nitrogen (BUN) P < 0.001 were significant. In conclusion, oxidative damage can occur in cells in nephrotoxicosis, the use of antioxidants could be of benefit during treatment with chemotherapeutics.

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 …

This study examined 936 Ross-308 sex-separated broilers (468 males and 468 females) at 22 days of age. The chicks were fed with standard broiler starter diet for the first 21 days. Isonitrogenic grower diets (3045 versus 3222 kcal/kg M.E.) were offered to broilers housed in sex-separated and mixed-sex pens from days 22 to 43 during the experimental period. The final body weight of sex-separated chicks (1739.91 g) was greater than that of mixed-sex chicks (1714.81 g) at 43 days of age (P < 0.05). Neither growing method nor diet energy level had a significant effect on the body weight (except at 43 days of age) or body weight gain of broilers. However, effects of sex was significant (P < 0.01) on the body weight and body weight gain of broilers throughout the trial period. Sex-separated males were heavier than mixed-sex males at 36 and 43 days of age (P < 0.05). However, the diet energy level and growing method had no significant effect on feed consumption or the feed conversion rate (P > 0.05). Broilers consumed a high energy diet had a higher carcass yield and breast rate (%), but diet …
The Presence Of Mallophaga Species On Wild Partridge In The Elazığ District, Nursel Aksin
The Presence Of Mallophaga Species On Wild Partridge In The Elazığ District, Nursel Aksin
Turkish Journal of Veterinary & Animal Sciences
The purpose of this study was to determine the presence of Mallophaga species on wild partridges in the Elazığ region. We inspected 68 partridges for Mallophaga species between November and January from 1996 to 2000. At least one species of Mallophaga was found on 48 partridges. Three species of Mallophaga were found on infested partridges. These species, were Goniodes dispar (Burmeister, 1838), Goniocotes pusillus (Nitzch in Giebel, 1866) and Menacanthus lyali (Rodriguez Caabeiro et al.,1983). These three Mallophaga species have not been reported before in Turkey.
