Item Investigation of the effects of Pine and Chestnut Honey on wound healing(Ankara Üniversitesi Veteriner Fakültesi, 2022) Sevin, Sedat; Veteriner; Veteriner FakültesiThis 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.Item Rumen fermentation characteristics of rams fed supplemental boric acid and humic acid diets(Ankara Üniversitesi Veteriner Fakültesi, 2002) Sızmaz, Özge; Veteriner; Veteriner FakültesiThe 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.
