Öğe Dietary fig seeds improve growth performance and antioxidant capacity of quail(South African Journal Of Animal Sciences, 2023) Tufan, T.; Bolacali, M.; Irak, K.; Arslan, C.; Ozcan, C.; Kaplan, O.; Irmak, M.The aim of this study was to determine the effect of the addition of fig seed (FS) as a feed additive in quail rations on growth performance, carcass parameters, and antioxidant status. A total of 2000 one day-old quail chicks were allocated to a control diet (C; n = 400) or diets supplemented with 0.25% (FS0.25; n = 400), 0.50% (FS0.50; n = 400), 0.75% (FS0.75; n = 400), and 1.00% (FS1.00; n = 400) FS. There were five replicates of 80 chicks for each treatment. At the end of the study, the highest body weights and average daily live weight gains were observed in the FS1.00 group, whereas the lowest BW was observed in the control group. There was no statistical difference between the groups in terms of feed consumption, but the feed conversion ratios of all experimental groups were higher than the control group. The addition of FS had a marked effect on slaughter, hot, and cold carcass weights; and leg, chest, and wing weights compared to the control. Addition of FS to the ration increased total protein and albumin levels, whereas it decreased total oxidant status and alkaline phosphatase. Glucose and uric acid values showed a variable trend. As a consequence, it was concluded that the addition of fig seed as a feed additive at 0.50-1.00% of quail rations could be beneficial based on growth performance, carcass characteristics, and blood parameters.Öğe Effects of gender and dietary date palm extract on performance, carcass traits, and antioxidant status of Japanese quail(South African Journal Of Animal Sciences, 2021) Bolacali, M.; Irak, K.; Tufan, T.; Kucuk, M.This research examined effects of gender and dietary inclusion of date palm extract (DPE) on growth, carcass characteristics, oxidative status and serum characteristics of Japanese quail. One thousand chicks were allocated to five replicates of treatment and gender groups composed of 20 chicks. The treatments were a basal diet and four groups augmented with 0.25%, 0.50%, 0.75%, and 1.00% DPE. The interaction of gender and treatment was significant for bodyweight (BW) at 42 days, average daily bodyweight gain (BWG), feed intake (FI), weights of most carcass components, and the serum profile. Females had better performance to 42 days than males (P<0.05). In addition, females had higher hot and cold carcass weights, breast percentage, liver percentage, intestine percentage, total protein, albumin, triglyceride (TRIG), total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress indexes (OSIs) (P<0.001). Males had higher percentages of hot carcass, cold carcass and heart, and their levels of cholesterol (CHOL), highdensity lipoprotein (HDL), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) values were greater than females (P<0.001). Birds fed 0.50% DPE grew faster, were more efficient, and had heavier live and carcass weights at 42 days than those fed the basal diet. However, treatment effects and their interaction with gender on growth, feed intake and the serum profile were unremarkable compared to the gender main effect. Dietary augmentation with 0.50% DPE might enhance the performance of quail between 14 and 42 days old.Öğe Investigation of the effects of live weight and sex on oxidative stress and antioxidant parameters in healthy geese - preliminary study(Eugen Ulmer Gmbh Co, 2023) Yavuz, E.; Irak, K.; Celik, O. Y.; Bolacali, M.; Ergiden, Y.; Tufan, T.; Gurgoze, S.This study was carried out to determine the effects of live weight and sex on oxidant respective antioxidant status in clinically healthy geese. The total antioxidant level (TAS), total oxidant level (TOS), oxidative stress index (OSI), ferric ion reducing agent antioxidant power (FRAP) and Glutathione (GSH) levels were measured in serum samples from a total of 41 geese (18 males and 23 females) at 9 months of age, bred under the conditions of local breeders. While it was determined that live weight and sex had an effect on TOS and FRAP parameters, but it did not affect TAS, OSI and GSH values in geese. A negative relationship between live weight gain and TOS levels was found. It was detected that FRAP levels were higher in female geese than in males (p < 0.05). It was concluded that the relationship between TOS level and live weight of healthy geese should be further investigated and that the FRAP level could be evaluated as an indicator of antioxidant power in healthy geese of different sexes.Öğe Investigation of the protective effect of chitosan against arsenic-induced nephrotoxicity and oxidative damage in rat kidney tissue(Polska Akad Nauk, Polish Acad Sciences, Univ Warmia & Mazury Olsztyn, 2024) Irak, K.; Celik, O. Y.; Bolacali, M.; Tufan, T.; Ozcan, C.; Yildirim, S.; Bolat, I.Arsenic is an important metalloid that can cause poisoning in humans and domestic animals. Exposure to arsenic causes cell damage, increasing the production of reactive oxygen species. Chitosan is a biopolymer obtained by deacetylation of chitin with antioxidant and metal ion chelating properties. In this study, the protective effect of chitosan on arsenic -induced nephrotoxicity and oxidative damage was investigated. 32 male Wistar-albino rats were divided into 4 groups of 8 rats each as control group (C), chitosan group (CS group), arsenic group (AS group), and arsenic+chitosan group (AS+CS group). The C group was given distilled water by oral gavage, the AS group was given 100 ppm/day Na-arsenite ad libitum with drinking water, the CS group was given 200 mg/kg/day chitosan dissolved in saline by oral gavage, the AS+CS group was given 100 ppm/day Na-arsenite ad libitum with drinking water and 200 mg/kg/day chitosan dissolved in saline by oral gavage for 30 days. At the end of the 30 -day experimental period, 90 mg/kg ketamine was administered intraperitoneally to all rats, and blood samples and kidney tissues were collected. Urea, uric acid, creatinine, P, Mg, K, Ca, Na, Cystatin C (CYS-C), Neutrophil Gelatinase Associated Lipocalin (NGAL) and Kidney Injury Molecule 1 (KIM -1) levels were measured in serum samples. Malondialdehyde (MDA), Glutathione (GSH), Catalase (CAT) and Superoxide dismutase (SOD) levels in the supernatant obtained from kidney tissue were analyzed by ELISA method. Compared with AS group, uric acid and creatinine levels of the AS+CS group were significantly decreased (p<0.001), urea, KIM -1, CYS-C, NGAL, and MDA levels were numerically decreased and CAT, GSH, and SOD levels were numerically increased (p>0.05). In conclusion, based on both biochemical and histopathological-immunohistochemical-immunofluorescence findings, it can be concluded that chitosan attenuates kidney injury and protects the kidney.Öğe Occurence and genotype distribution of Cryptosporidium spp., and Giardia duodenalis in sheep in Siirt, Turkey(Polska Akad Nauk, Polish Acad Sciences, Univ Warmia & Mazury Olsztyn, 2023) Celik, B. Aslan; Celik, O. Y.; Ayan, A.; Kilinc, O. Orunc; Akyildiz, G.; Irak, K.; Selcuk, M. A.Cryptosporidium spp., and Giardia duodenalis are intestinal protozoan parasites known to infect humans and various animals and cause diarrhea. This study aimed at determining the prevalence and genotype of Cryptosporidium spp. and Giardia duodenalis in sheep in different locations of Siirt province. The fecal material for this study was collected from 500 sheep in different locations of Siirt province, Turkey. Fecal samples obtained from sheep were examined for Cryptosporidium spp. by Kinyoun Acid Fast staining and the Nested PCR method. Microscopic and Nested PCR methods revealed a prevalence of 2.4% (12/500) and 3.6% (18/500), respectively. Sequence analysis revealed the presence of C. ryanae, C. andersoni, and zoonotic C. parvum. In terms of Giardia duodenalis, 8.4% (42/500) and 10.2% (51/500) prevalence was determined using Nativ-Lugol and Nested PCR methods, respectively. Using sequence analysis, zoonotic assemblages A and B as well as assemblages E and D were detected. As a result of this study, both the prevalence of Cryptosporidium spp. and Giardia duodenalis and the presence of species that appear to be host-specific, as well as those known to be zoonotic, were revealed. A large-scale study is needed to understand the impact of these agents on sheep farming and their consequences on human health.Öğe Oxidant/Antioxidant Status and Certain Trace Elements Relationship in Hair Goats Naturally Infected by Neospora caninum(Hellenic Veterinary Medical Soc, 2022) Celik, B. A.; Celik, O. Y.; Irak, K.; Bolacali, M.This study was performed to determine the prevalence of Neospora caninum in female hair goats raised in different locations of the Siirt province of Turkey, and to investigate the total antioxidant status (TAS), total oxidant status (TOS), Zinc (Zn), and Copper (Cu) levels of the infected goats. The animal material of the study consists of a total of 184 female hair goats that are between 1 to 6 years old with the random sampling method. Investigation of the N.caninum antibodies was then performed using a commercial ELISA kit. The results of the ELISA tests reveal that the prevalence of N. caninum in the province of Siirt was 10.33% (19/184) positive, 7.61% (14/184) suspected, and 82.07% (151/184) negative. According to the ELISA test results, 10 seropositive and 10 seronegative sera samples were used in the TAS, TOS, Zn, and Cu analysis. The TAS (p<0.01) and Zn (p<0.001) levels of goats positive with N. caninum were found to be lower compared to those of the seronegative goats, while their TOS and Cu levels were higher (p<0.05). This study was the first to determine the N.caninum prevalence in the goats raised in the province of Siirt. It was concluded that it would be beneficial to take precautionary measures, as well as further studies with larger scopes to be performed which should also involve dogs as the definitive host. Furthermore, the oxidative stress parameters (TAS, TOS) and certain trace elements (Zn, Cu) were found to be affected by Neosporosis, which should be useful in the diagnosis and treatment of the disease.Öğe Serum C-Reactive Protein, Erythrocyte Sedimentation Rate, and White Blood Cell Count in Romanov Sheep with Infectious Keratoconjunctivitis(Hellenic Veterinary Medical Soc, 2018) Akgul, G.; Akgul, M. B.; Irak, K.; Celik, O. Y.; Demirbilek, Kahya S.; Uzabaci, E.This study aimed to evaluate the use of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and white blood cell count (WBC) as markers of the severity of inflammation in the eyes of the Romanov breed sheep with infectious keratoconjunctivitis. A total of 10 Romanov breed sheep between the 1.5 and 2 years of age, including the ones carrying infectious keratoconjunctivitis (G1, n = 5) and healthy ones (G2, n = 5), which were housed under the same care and nutrition conditions were examined, in a sheep breeding enterprise within the boundaries of Siirt province. Staphylococcus aureus sp., Clostridium spp., and Penicillium spp. were detected based on the microscopic morphology of the colonies in swabs collected from the eyes of sick animals. Biochemical tests were performed relevant to the suspected agents while no growth was detected in the swabs of the control group. There was a statistically significant difference in serum CRP and WBC levels between the G1 and G2 groups (p<0.05). No statistically significant difference was found between the values of the other parameters tested. Higher levels of CRP and WBC were determined in sheep having infectious keratoconjunctivitis, are compared to those in healthy animals.
