In this study, we aimed to determine the effect of probiotic supplementation of Lactobacillus reuteri E81 (LRE; 200, 400, 600 mg/kg) to the diets of Japanese quail (Coturnix coturnix japonica) reared under heat stress (HS) on serum adipokine (visfatin, adiponectin and chemerin), intestinal (citrulline) and thyroid hormone levels. 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).

In the present study, the effects of Lactobacillus reuteri E81 (LRE) supplemented at different doses (200, 400 and 600 mg/kg) into the diets on performance, meat quality and internal organ weights of Japanese quail (Coturnixcoturnix japonica) were investigated under heat stress (HS) conditions (37°C). 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°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.

This study aimed to investigate the effects that including different levels of oregano essential oil (Origanum syriacum L.) (200, 400, and 600 mg/kg) in the diets of laying hens had on performance, egg quality, and intestinal morphology, as well as egg malondialdehyde (MDA) levels, blood lipid peroxidation, and oxidative stress parameters. The study used a total of 120 Lohmann white laying hens aged 20 to 22 weeks. The experiment comprised the following three treatment groups, based on the dosages of oregano essential oil: 200 mg/kg (A), 400 mg/kg (B), 600 mg/kg (C); and a control group (K) that did not use oregano essential oil. Each group included 30 hens and each was divided into six subgroups with five hens each. In this study, feed intake and egg weight were significantly higher in the treatment groups than in the control group (P=0.046; P< 0.001). There was no difference among the groups in terms of eggshell strength, egg shape index, eggshell thickness, albumin index, or yolk index. However, there was a significant difference in eggshell weight, yolk color and Haugh unit in the experimental groups (P=0.015; P=0.031; P=0.042). The MDA levels in the yolk were lowest in group A (P< 0.05). In all groups with the exception of group A, yolk and serum MDA levels increased while superoxide dismutase, glutathione peroxidase, and catalase decreased as the doses of oregano essential oil increased (P< 0.001; P< 0.001; P< 0.01; P< 0.001). There was no significant serum glutathione level. In the histological analysis of the intestine, the villus height was higher in group C than in the control group (P=0.010). Based on these results, we concluded that 200 mg/kg was the most effective dose of oregano essential oil for improving performance, egg quality, and intestinal morphology while reducing oxidative stress in laying hens.
