The purpose of this study was to investigate the effect of sodium bentonite supplementation on fattening performance and some blood parameters in Tuj lambs. In the study, 18 male lambs were divided into 3 groups. While the control group was fed with basal ration, the experimental groups were fed with sodium bentonite supplementation 1% and 2% dose in addition to the basal ration. On the 0th, 15th, and 30th days of the study, there was no statistically significant difference between groups in terms of mean live weights, live weight gain, daily live weight gain, daily feed consumption and feed conversion ratio (P>0.05). On the 45th day of the study, the difference between the groups in terms of live weight gain, daily live weight gain and feed conversion ratio were statistically found significant (P0.05).The use of sodium bentonite in Tuj breed lambs was statistically found significant in terms of malondialdehyde (MDA), superoxide dismutase (SOD) and catalase enzyme activities (CAT) (P <0.05). In conclusion, the use of sodium bentonite in Tuj lambs positively affected fattening performance. When the blood antioxidant parameters were examined, increase in SOD and CAT values was protective against oxidative damage in lambs used sodium bentonite. However, the increase in MDA value has doubted the safety sodium bentonite use in lambs.

The aim of this study is to investigate the effect of essential oil mixture supplemented in drinking water on antioxidant capacity and intestinal health in geese. One hundred eight chicks (which were 3 days old) were randomly allocated to 3 groups and each group was allocated to 6 subgroups. Research groups have been as follows: C (Control; without supplementation); E1 (0.4 ml/L essential oil mixture supplementation) and E2 (0.8 ml/L essential oil mixture supplementation). The duration of the experiment was 13 weeks. In the first 4 weeks of the trial, the animals were fed for the chick period. In the last 9 weeks of the trial, geese were fed in the pasture under the conditions of Kars province. In the 4th week and at the end of the experiment, GSH exhibited a linear response (P=0.008 and P=0.004, respectively). However, MDA, GSH, SOD, GPx, CAT, nitric oxide, ceruloplasmin, albumin, total protein and globulin were not affected. At the end of the experiment, acetic acid, butyric acid, isocaproic acid and total short-chain fatty acid concentrations were linearly affected with the gradued level of essential oil mixture. There were no significant differences in propionic acid, isobutyric acid, valeric acid, isovaleric acid, caproic acid and BCFA concentrations. In conclusion, water containing essential oil mixture in geese can be used to improve antioxidant capacity and intestinal health.
