Tekce, E.; Çınar, K.; Bayraktar, B.; Takma, Ç.; Gül, M.
This study investigated the effects of an essential oil mixture (EOM; Eucalyptus globulus labill, Tymus vulgaris, Cymbopogon nardus, and Syzgium aromaticum) added to drinking water on temperature-stressed broilers. 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.

The purpose of this study was to examine the effect of adding an essential fatty acid mixture (EOM; Eucalyptus globulus Labill, thymus vulgaris, Cymbopogon nardus, and Syzygium aromaticum) to the drinking water in the heat stress broilers on the adipokine (Apelin, BDNF) response, the histopathologic changes in liver and intestines, and some biochemical parameters. This study lasted for a total of 42days, including the physical exercise period (7days) and the fattening period (35days). A total of 400 Ross 308 male broilers (1-d-old) were randomly divided into 8 groups (50 animals per group), each of which was exposed to various conditions of temperature (C: 22°C and SC: 36°C) and treatment dose (C, 250, 500 and 750mL/1000 L). Each group was divided into 5 subgroups, each comprising 10 animals. In the stress-free groups, whereas the Apelin level linearly decreased, the BDNF level linearly increased. In histopathology, the liver tissue was found to be normal in all groups whereas the duodenum villi length was found to increase in the group of 750mL/1000 L. No statistically significant difference was found between the stressed groups and the non-stressed groups in terms of VLDL, Glucose, Total bilirubin, ALT, and TG (p >.05). While Apelin level increased in the stressed groups, the BDNF level increased in the group of 250mL/1000 L. In the histopathological examination, a small amount of coagulation necrosis was detected in hepatocyte, a diffuse hydropic degeneration was observed in hepatocytes, and finally a dilatation and hyperaemia were seen in sinusoid in the groups of EOM-500mL/1000 L and EOM-750 m/1000 L compared to the control group. Whereas there was no difference between the group of EOM-250mL/1000 L and the control group in terms of duodenum villa length, there was a significant decrease in other groups (p <.00). In conclusion, this study showed that adding 250mL/1000 L of EOM to the drinking water had a positive effect on the serum levels of Apelin and p-BDNF in the groups exposed to stress (p <.05).HIGHLIGHTS Heat stress results in serious annual economic losses in the poultry industry. Essential oil fatty mix acids have positive effects on poultry health. Apelin and BDNF may be a protective factor against deleterious consequences of chronic exposition to heat stress.

Cardiac troponin (cTnI) and erythrocyte distribution width (RDW) have been used as specific markers for the evaluation of cardiac arrhythmias and myocardial diseases. In this experimental study, we aimed to determine the dose-dependent administration of an Essential OilMixture (EOM) (Eucalyptus globulusLabill, Thymus vulgaris, Cymbopogon nardus, and Syzygiumaromaticum) on the serum erythrocyte indices and myocardial damage. We used 400 male, oneday-old, Ross-308 chicks. Each group ((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) was further divided into eight groups with 50 animals. Each group of 50 chicks was further subdivided into five groups with 10 animals in each compartment. The results showed that the WBC, RBC, HGB, HCT, RDWSD, RDW-CV, and Lymphocyte decreased in groups without exposure to temperature stress (22ºC) compared to the 22ºC control group; whereas, CnTnI, MCHC, NEUT, and IG (p<0.05) increased compared to the control group. In groups exposed to temperature stress (36ºC), the WBC, HGB, HCT, RDW-SD, and Lymphocyte decreased compared to the control group, but MCH, MCHC, NEUT, and IG increased compared to the control. However, cTnI, CK, creatinine, RBC, and RDW had no effect on CD, MONO, EO, and BASO (p<0.05). EOM mixture had no effect on hematological and biochemical parameters.

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.

Tekce, E.; Gül, M.
The biochemical and hematological blood values of broilers fed under heat stress and that were administered Origanum syriacum (OS) essential oil were investigated in this study. In total, 400 male broilers (Ross-308; age, 1 day) were used for the period of 42-days of the study. The experiment included ten groups (n = 50/group; each group divided into five sub-groups): normal heat, 22°C: basal feed (BF)-positive control group (PC), BF + 100 ppm OS; BF + 300 ppm OS; BF + 600 ppm OS). Heat stress, 36°C: BF-positive control group (PC), BF + 100 ppm SOS; BF + 300 ppm OS; and BF + 600 ppm OS). Biochemical and hematological parameters were measured in blood collected into EDTA tubes. Total bilirubin, cholesterol, low-density cholesterol, Na+, Ca2+, and Mg2+ increased, whereas alanine aminotransferase, aspartate aminotransferase, creatine kinase (CK), CK-MB, urea, uric acid, Cl–, and K+ decreased (p<0.05); however, no changes were detected in the other hematological values.
