Effects of Flunixin Meglumine on Oxidant and Antioxidant System after Disbudding with Caustic Paste in Calves

Background: Disbudding is often practiced in modern farm because of the reasons for the safekeeping of the animal, other animals lessen the risk of injury and less aggressive behavior. Without regard to the method of disbudding leads to disruption behavioral changes, cardiac and endocrine responses related pain of animals. Sedation, local anesthesia and analgesia are performed studies in order to eliminate of cardiac, endocrine, behavioral response which is caused by pain associated with disbudding. In this study, it was aimed to determine the effect on the oxidant and antioxidant system in the calves of disbudding by using the caustic paste with and without painkiller.Materials, Methods & Results: The animal material of the study was created 24 Simmentals calves in different sexes on average 2 weeks (± 2 days) and 50 kg (± 15 kg) live weight. The cases were randomly divided into 2 groups of 12 calves in each group. In the group I (analgesia group); caustic paste+painkiller (2.2 mg-1 flunixin meglumine intravenous, IV) and group II (non-analgesia group); as disbudding applied with caustic pasta application only were divided into 2 groups. In the I group, 15th min before the application, flunixin meglumine at a dose of 2.2 mg-1 was administered IV and the horn blunting was performed by caustic paste method. Blood samples were taken at 15, 30 and 60th min after completion of horn blunting and physiological findings were recorded. In group II, the horns of the calves were disbudding with the same technique (but no analgesia aplication). Blood samples were taken at 15, 30 and 60th min after completion of horn blunting and physiological findings were record. Cortisol, glucose, total oxidant capacity (TOC) and total antioxidant capacity (TAC), 8-hydroxy-2’-deoxyguanosine (8-OHdG), glutathione (GSH), superoxide dismutase (SOD) enzymes measurements (ELISA) were performed in both groups. TOC and TAC tests were used to determine the oxidative stress index in the obtained serum, 8-OHdG measurement which is the most sensitive and most frequent oxidative DNA damage indicator for determination of oxidative damage; GSH, SOD enzymes were analyzed by ELISA using commercial kit for the evaluation of antioxidant potential. For evaluation of pain in animals, cortisol (ELISA) and glucose level in serum were measured with ELISA by using commercial kit. In the group without flunixin meglumine, cortisol was increased significantly from the 15th min (P < 0.05), but there was no increase in the 30 and 60th min in painkiller administered group. Glucose levels were higher in the group not using painkillers than those used at 15th (P < 0.001) and 30, 60th min (P < 0.05). TOC (P < 0.001) and 8-OHdG (P < 0.05) values were significantly higher in the group without painkiller while TAC, GSH and SOD levels (P < 0.05) were significantly decreased.Discussion: It has been observed that sedation (such as xylazine) and local anesthesia (such as lidocaine) use removed pain-induced stress in the disbudding with caustic paste in calves. However, in order to remove the endocrine response, it is necessary to combine the anesthesia protocol with the analgesic (such as flunixin meglumine) combination. According to our results concluded that the painkiller given before the disbudding process was supporting the antioxidant system, reducing the level of cortisol and oxidative stress

Antimicrobial and Antioxidant Effects of Some Turkish Fodder Plants Belongs to Fabaceae Family (Vicia villosa, Trifolium ochroleucum and Onobrychis altissima)

In this study, the antimicrobial and antioxidant activities of Vicia villosa, Trifolium ochroleucum and Onobrychis altissima samples were investigated. For this purpose, plant extracts were tested against 3 fungus, 4 Gr(-) and 3 Gr(+) bacteria; additionally the glutathione (GSH) level and total phenolic content were measered spectrophtometrically and total antioxidant capacity (TAC) was done by ELISA method. According to results methanolic extracts of Vicia villosa, Trifolium ochroleucum and Onobrychis altissima exhibited no antimicrobial activities against test microorganisms. Trifolium ochroleucum extract has the highest levels for GSH and TAC (462.06 +/- 25.89 mmol/L, 30.35 +/- 0.003 mg GAE/g dw respectively). Vicia villosa extract is showed the highest antioxidant capacity (4.416 +/- 0.107 mM)

Effect of Seed Powder of a Herbal Legume Fenugreek (Trigonella foenum-graceum L.) on Growth Performance, Body Components, Digestive Parts, and Blood Parameters of Broiler Chicks

WOS: 000328301100018The aim of this study was to investigate the effects of dietary Trigonella foenum-graceum L. seed powder (TFGSP) on growth performance, blood glucose, protein and lipid profile of broilers (Ross-308). One hundred ninety two, 1-d old mixed sex broiler chicks were allocated to 5 dietary treatments in which 0, 5, 10, 20 and 40 g TFGSP doses per kg commercial broiler diet were added for a period of 42 days. The results showed that body weight and the breast weight decreased after TFGSP treatment compared to control (P<0.05). Feed intake decreased after 5 g TFGSP treatment while 40 g TFGSP treatment decreased feed efficiency and leg weight compared to control (P<0.01). There was no significant difference in weights of digestive system parts, except duodenum weight and lipid oxidation between control and treatment groups. A 20 g TFGSP treatment enhanced blood glucose level (P<0.01), but decreased triglyceride level (P<0.01) compared to control. At 40 g TFGSP the blood cholesterol decreased (P<0.05) but LDL level increased compared to control (P<0.01). In conclusion, TFGSP addition to broiler diet decreased appetite and, consequently, reduced growth performance, more likely, attributting to the enhanced blood glucose level.Research Funding Committee of Mustafa Kemal UniversityMustafa Kemal University [07B0303]We are grateful to Research Funding Committee of Mustafa Kemal University for supporting the Project # 07B0303
