Apelin level in the blood serum samples obtained from the jugular vein of the sheeps was determined using ELISA method. As a result of the analyses, it was determined that the level of apelin was statistically different between the races; between lactating sheep and pregnant sheep; and sheep and rams. There was no difference between the BCS groups (p > 0.05). Race and sex interaction as well as race, sex and BCS triple interaction effects were found significant (p < 0.05). It was observed that the sheep belonging to the White Karaman–Kangal race were 18 times more likely to be infected with the virus. A decrease in apelin level was observed in the sheep with infection, and it was found that the risk of infection was 0.37 times higher in rams than in lactating sheep (p < 0.05).

Retinohipotalamikpineal eksen yoluyla düzenlenen sirkadiyen ritmin düzenleme merkezi anterior hipotalamustaki SCN (suprakiazmatik çekirdek) ve orta beyindeki pineal bez’dir. Sirkadiyen ritimde, vücut ısısı, uyku uyanıklık döngüsü, melatonin, kortizol hormonu önemli göstergeleri olarak gösterilmektedir. Vücutta hormonların büyük çoğunluğu sirkadyen ritimle düzenlenmektedir. Vücutta kan basıncı, immün sistem aktivitesi, kan koagülasyonunu ve gastrik ve renal fonksiyonları etkilemektedir. Melatonin, bilinen en güçlü antioksidan moleküllerden birisidir. Fizyolojik melatonin ritmi, otonom sinir sisteminin düzeni, kan basıncı, kan şekeri regülasyonu, sirkadiyen gen ekspresyonu üzerinde önemli fizyolojik rolü bulunmaktadır. Sirkadiyen ritmin bozulması başta kanser olmak üzere birçok hastalığın ortaya çıkmasına yol açması nedeniyle sirkadiyen ritim fizyolojisi ve düzenlenmesine yönelik çalışmalar önemli bir konu haline gelmiştir. Bu kapsamda, sirkadiyen ritim fizyolojisi ve fizyolojik melatonin ritminin konularının incelenmesi hedeflenmiştir

On day 7 of the trial, the animals were assigned to 8 groups [Control temperature (CT): control (C, without LRE supplementation), LRE-200, LRE-400 and LRE-600 and HS: control (HSC), SLRE-200, SLRE-400 and SLRE-600], each composed of 56 animals of equal body weight. Each group was divided into 4 subgroups withg 14 animals per compartment. During the experiments, the temperature applied to the CT-groups C, LRE-200, LRE-400 and LRE-600 was 25°C and to the HS-groups HSC, SLRE-200, SLRE-400 and SLRE-600 was 37°C. At the end of the study (days 21 and 42), a dose-dependent decrease in citrulline, chemerin, adiponectin, and thyroid hormones and a dose-dependent increase in the visfatin hormone level (p < 0.01) due to LRE supplementation were observed in the HS and CT groups compared to its control. In conclusion, the present study showed that dietary supplementation with 600 mg/kg of LRE affected serum chemerin, adiponectin, T3, T4, TSH and visfatin levels in Japanese quail raised under heat stress (p < 0.001)

For the experiments, 448 one-day old quails were used. Seven days of training (physical exercise) and a 35-day fattening period were applied. on day 7 of the trial, 8 groups [4 under control temperature of 25 degrees C (CT): control (C), LRE-200, LRE-400 and LRE-600 and 4 under HS: control (HSC), SLRE-200, SLRE-400 and SLRE-600] were formed, each group consisting of four replicates with 14 quail each. At the end of this study, the CT group fed 400 mg/kg LRE showed the best performance results, whereas no effect was found for groups under HS in comparison to the control group (HSC). Samples taken on the 21st and 42nd day revealed that addition of probiotics in the CT and HS groups induced no effect on weight of the internal organs (p > 0.05). Analysis of meat quality on the 21st day showed that LRE caused an increase in pH in both the HS and CT groups. Further, 400-mg/kg LRE supplementation induced an increase in thiobarbituric acid reactive substances (TBARS) in the group under HS. in the CT groups on day 42 no effect of LRE was found on colour parameters or on the TBARS value, except for a decrease in the pH value in the LRE supplemented groups compared with the control. in HS groups a decrease in the L* value and an increase in the TBARS value was found compared to CT groups (p < 0.05), but there was no effect on other colour parameters or pH value. in conclusion, in the present study supplementation of different doses of LRE E81 to quail diets had no effect on performance, internal organ weight or meat quality under HS.scientific research projects commission of Bayburt University, Bayburt, Turkey [2018/02-69001-02]This study was funded and supported by the scientific research projects commission of Bayburt University, Bayburt, Turkey (Project code: 2018/02-69001-02). the authors declare that they have no conflict of interest

Cattle provide β-Carotene by eating grass and feeds since they cannot synthesize. β-carotene deficiency causes many metabolic disorders in animals. The aim of this study was to determine the effects of season, age, lactation and dry period on β-Carotene level at Local Black Cattle whIch are only breed In AnatolIa. This study was carrIed out in native cattle race (Local Black) that breds in our country, 80 of which belong to the protection flocks that are grown in the northern parts of Central Anatolia.

The birds were divided into two groups, one of which was exposed to heat stress (HS). Within each group, four subgroups, each including 64 birds, were created for the three treatment doses (200, 400 or 600 mg/kg) of LRE and the control. The experiment was started with day-old birds, kept at a temperature of 25 °C or 37 °C. After a 7-day adjustment period, the LRE supplementation lasted for 35 days. The levels of different adipokines, including visfatin (VF), adiponectin (ADP), chemerin (CHEM), as well as the concentration of plasma citrulline (CIT) and the levels of thyroid hormones (T3 and T4) and thyroid-stimulating hormone (TSH) in the blood were measured at 21 and 42 days of age. A significant correlation (P < 0.01) was found between LRE supplementation and the decrease in serum VF, ADP, CIT, T3 and ...

The performance parameters (body weight, average daily weight, feed intake, and feed conversion ratio), meat quality, and thiobarbituric acid-reactive substances (TBARS) were evaluated. In a 42-d study, 400 Ross-308 male chickens (1-d-old) were randomly assigned to 8 different groups (n = 50), each containing 4 subgroups (n = 8) (22°C Control (C), C + 250 mL/1,000 L, C + 500 mL/1,000 L, C + 750 mL/1,000 L), 36°C (stress control (SC), SC + 250 mL/1,000 L, SC + 500 mL/1,000 L, SC + 750 mL/1,000 L). Adding 750 mL/1,000 L at 22°C and 250 mL/1,000 L at 36°C was more beneficial to the fattening performance parameters than those in the control group. EOM reduced liver weight but increased abdominal fat in the SEOM-250 groups but did not affect other organ weights. EOM had no effect on the TBARS or the b* color parameter while it augmented the a* and L* coordinates of meat color.
