    Investigation of the effects of Pine and Chestnut Honey on wound healing
    (Ankara Üniversitesi Veteriner Fakültesi, 2022) Sevin, Sedat; Veteriner; Veteriner Fakültesi
    This study aimed to investigate the effect of creams containing pine and chestnut honey on wound healing in rats. The animals were divided into the following four groups: a control group (A), a group treated with only basic cream ingredients (B), a group treated with pine honey cream (C), and a group treated with chestnut honey cream (D). Full-thickness skin wounds were created on the back of each rat (14 per group) with a 10-mm diameter punch instrument. In each group, skin samples were taken from seven rats on day 7 and from the remaining seven rats on day 14. The effects of the creams on wound healing were assessed by histopathological examination and hydroxyproline assays. The histopathological examination showed that chronic inflammation significantly decreased in group D compared to the control group (P<0.05). Furthermore, the levels of granulation tissue and granulation tissue/fibroblast maturation in skin samples taken on day 14 were also significantly lower in group D compared to the control group (P<0.05). It was observed that the neovascularization values of skin samples taken on day 7 were lower in group D than in the control group (P<0.05). Also, the difference in hydroxyproline levels between groups B and D was statistically significant (P<0.05). The results showed that the cream containing chestnut honey had a positive effect on wound healing.

    Rumen fermentation characteristics of rams fed supplemental boric acid and humic acid diets
    (Ankara Üniversitesi Veteriner Fakültesi, 2002) Sızmaz, Özge; Veteriner; Veteriner Fakültesi
    The aim of the study is to investigate the effects of humic acid and boric acid as feed additives on rumen fermentation parameters in rams. For this purpose, 3 yearling rams were used in this experiment. Rams in each treatment; a control with no supplements (C), 180 ppm boric acid (B) and 5 ml/kg humic acid (H) with 65:35 forage to concentrate ratio. Each experimental period lasted 14 days, with 12 first days of diet adaptation. Totally, the experimental period lasted 42 days. In both time periods (0 and 3h after feeding), there were no significant differences (P>0.05) on rumen pH, ammonia, protozoa count, estimated methane production and volatile fatty acid composition. However, butyric acid concentration tended to be higher in experimental groups (P=0.08) compared with control. As a result of this study, these feed additives did not modify the rumen milieu and showed no negative effect in rams.

    Use of essential oil mixture to improve antioxidant capacity and concentrations of cecum short-chain fatty acids in Turkish domestic geese (Anser anser)
    (Ankara Üniversitesi Veteriner Fakültesi, 2022) Yıldız, Gültekin; Veteriner Hekimliği; Veteriner Fakültesi
    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.
