  Ülker, U.; Kızıl, S.; Bayraktar, B.; Alçığır, M.E.; Kul, O.; Kaya, H.; Ürüşan, H.; Aydemir, Ş.; Kotan, G.C.; Önel, A.U.

  Background: The aim of this study is to examine the microbiological, clinical, physiological and pathological findings of natural polymicrobial infection developing in a wistar rat colony under long-term observation. Methods: In this study, 70 male Wistar albino rats, 3 years old, raised by conventional methods and housed in a cage environment were used. Thirteen rats with clinical symptoms such as torticollis and rotation were sacrificed for microbiological and histopathological examination after 14 days. For microbiological examination, the rapid diagnostic kit BBL Crystal system was used to identify bacterial agents in tissue and stool samples and the traditional culture method was used for isolation. Result: As a result of microbiological analysis, the rarely isolated Staphylococcus capitis (S. capitis) was isolated. Different Staphylococcus spp. It has been determined that the species can cause suppurative meningoencephalitis as well as septicemia in the brains of experimental animals., it is thought that polymicrobial infection will be useful for the identification of bacterial agents and infection prevention and treatment strategies.

  Progranulin (PGRN) is a multifunctional protein that is critical in the retention of embryos in the endometrium of the uterus and the protection of cervical tissue during fetal growth. In case of PGRN release and dysfunction, cervical tissue may remodel (regeneration) and lead to the risk of abortion. Serum PGRN level in sheep and its variation according to different physiological periods and its relationship with some biochemical parameters are unknown. In this study, the relationship between early lactation, early and late pregnancy serum PGRN levels and some biochemical parameters in Akkaraman sheep was investigated for the first time. In the literature search, no similar studies were found on the relationship between early lactation, early and late pregnancy serum PGRN levels and some biochemical parameters in Akkaraman sheep. The research was carried out on 90 Akkaraman sheep reared in the same herd under the same care and feeding conditions. In the study, Akkaraman ewe were divided into 3 groups as early lactation, early pregnancy and late pregnancy. 1st group is early lactation period ewe (first 60 days of lactation), (n = 30), 2nd group is in the first period of pregnancy (on the 0-90th day of the first pregnancy (n = 30)), 3rd group is in the late pregnancy of pregnancy (100-150 days of pregnancy (n = 30)) was created. Blood samples from vena jugularis were taken before morning feeding from the animals that formed the study groups. PGRN levels in serum were determined by ELISA method. In addition, glucose, calcium (Ca), magnesium (Mg), phosphorus (P), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), very low density lipoprotein (VLDL) levels were analyzed in biochemistry autoanalyzer. As a result of the study, lactation and early pregnancy and late pregnancy mean serum PGRN levels were determined as 1.93, 1.78, 1.33 ng mL-1, respectively. The serum PGRN, glucose, Ca, Mg, P, TC, TG, LDL, HDL and VLDL levels of sheep with late pregnancy, early lactation and early pregnancy periods, which constitute the study groups, were found to be statistically significant (P<0.05). Our results have shown that due to the physiological role of PRGN in keeping the embryo in the endometrium of the uterine and in preserving the cervical tissue during fetal growth, there may be a useful parameter in the pursuit of the pregnancy process.

  EFFECTS OF MENTHA PULEGIUM EXTRACT AND VITAMIN E SUPPLEMENTATION ON LAYING HENS PERFORMANCE, EGG QUALITY, ANTIOXIDANT ENZYME ACTIVITY IN SERUM

  Bolukbasi, Saziye Canan; Urusan, Hilal; Erhan, Muhammet Kuddusi

  The aim of this study was to investigate the effects of the supplementation of Mentha pulegium extract (MPE) and vitamin E on performance, egg quality and antioxidant enzyme activities of laying hens. The experiment study was conducted with 120 40 weeks old laying hens (Lohman LSL). Hens were given five dietary treatments of which each was repeated six times on 4 birds. Hens in the experiment groups were given 50 mg / kg MPE, 100 mg / kg MPE, 50 mg / kg vitamin E, 100 mg/kg vitamin E and the hens in control group were fed on basal diet. MPE and vitamin E supplementation did not make any change on feed consumption and egg weight but improved feed conversion ratio. Addition of 100 mg / kg MPE and vitamin E significantly increased the egg production. No significant difference were found between control and experimental groups in terms of shell thickness, yellowness, shape index and ratio of albumen, yolk and egg shell. However, MPE and vitamin E supplementation improved the shell breaking strength and Hough Unit. Dietary supplementation of MPE and vitamin E did not change AST, ALT, TG, cholesterol, HDL, LDL and glucose level in serum. Serum MDA value was decreased by MPE and vitamin E addition. Serum MDA levels were reduced by addition of MPE and vitamin E, but there was no difference in SOD activity among the groups. The addition of 50 and 100 mg / kg vitamin E significantly reduced the GSH-Px activity. As a result, 100 mg / kg MPE supplementation can be recommended as an alternative to antibiotic feed additives.

  The effect of apple cider vinegar and mushroom stalk supplementation on laying hens

  Karaalp, Musa; Aksakal, Vecihi; Sarikaya, Sevim Beyza Ozturk; Urusan, Hilal; Bayram, Bahri; Zulkadir, Ayhan

  The aim of this trial was to study the effects of consuming water with apple cider vinegar (ACV) and feed including mushroom (Agaricus bisporus) stalk (MS) on performance and certain egg characteristics. The hens were separated into four treatment groups (with 4 replicates and 6 hens per replicate). The experimental groups were control (not consumed ACV and MS), ACV (3 ml/l drinking water), MS (20 g/kg feed) and ACV+MS (combination). At the end of the experiment, among the performance criteria tested, body weight, feed intake, egg production and weight of eggs, and feed efficiency were not affected by the treatments (P>0.05). Treatments had no effect on physical external and internal egg characteristics. The amount of yolk malondialdehyde of the ACV and MS groups was lower than the control group (P<0.05) in stored eggs (28 d) (P<0.05).

  Effect of cold-press carrot seed oil on the performance, carcass characteristics, and shelf life of broiler chickens

  Ürüşan, H.; Erhan, M.K.; Bölükbaşı, S.C.

  Present study aims to assess the effects of cold-press carrot seed oil (CSO) on performance, gut microflora, some serum biochemical parameters, meat color and meat shelf life of broiler chickens by experimenting with young broiler chicks. Accordingly, hundred fifty day-old Ross PM 308 broiler chicks were randomly given three different dietary treatments supplemented with 0 (control), 100mL/kg or 200 mL/kg (CSO). Five replicates of 10 birds each. It was observed that the supplementation of CSO led to an increase in weight gain, hot carcass and carcass yield on day 42. Addition of CSO supplement in the basal diet had no effect on serumbiochemical parameters. The number of lactic acid bacteria was higher in the group of chicks fed on the diet supplemented with 200 ml/kg CSO than in the other groups. Compared to the control group, dietary CSO supplement reduced the MDA values in leg muscles. L* (lightness) and b* (yellowness) values of the breast muscles increased in the chicks fed with 200 ml/kg CSO. Dietary 100 ml/kg CSO supplementation decreased a* (redness) values of the breast and leg muscles.In conclusion, supplementation of CSO had resulted in positive changes on weight gain,carcas yield, lactic acid bacteria count and breast tissue shelf life. As a result, this study suggests that cold-press carrot seed oil can be used as a dietary source of natural antioxidant for broilers.
