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 Dietary supplementation with chitosan oligosaccharide affects serum lipids and nutrient digestibility in broilers(South African Journal Of Animal Sciences, 2020) Tufan, T.; Arslan, C.This research was conducted to determine the effects of supplementation of chitosan oligosaccharide (COS) on the growth performance, blood parameters, carcass traits, fatty acid composition of breast meat, and apparent nutrient digestibility in broiler chickens. A total of 375 one-day-old Ross 308 male chicks were allocated to a control diet (T1) or diets supplemented with 50 ppm (T2) and 100 ppm (T3) of COS. There were five replicates of 25 chicks for each treatment. All the experimental birds were fed a starter (days 1 - 4), grower (days 15 - 28), and finisher diet (days 29 - 42). No differences were detected among treatments for live weight, gain, feed intake or feed conversion, except that feed intake was depressed in T3 during the grower period. Serum total protein and albumin levels did not differ among the treatments. Serum total cholesterol, low density lipoproteins (LDL), very low density lipoproteins (VLDL) and triglyceride concentrations were reduced significantly by supplementation with COS, whereas the high density lipoprotein (HDL) concentration was significantly lower only for T2 relative to T1. The dressing percentage was significantly higher for T2 and T3 than for T1. Fatty acid composition of the breast meat was unaffected by the treatments. The digestibility of the diet and some of its constituents was affected in a graduated manner by the addition of COS. Thus, supplementation of broiler diets with COS improved carcass yield and had a hypolipidemic effect in improving the serum lipid profile.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 The effect of ?-carotene and vitamin E on metabolic profiles in nutritionally flushed sheep(South African Journal Of Animal Sciences, 2022) Irmak, M.; Kayri, V.; Tufan, T.; Coskun, D.; Ozcan, C.; celik, O. Y.; Denli, M.This study aimed to investigate the effects of 6-carotene and vitamin E on serum biochemistry, body condition score, and the number of offspring in sheep during the flushing period. To this purpose, forty Romanov sheep 45 (& PLUSMN;1 kg) body weight and 3 years of age were allocated into one of four experimental treatments with 10 replicates for 6 weeks: the control (only flushing), and three treatment groups injected intramuscularly with 1, 2, and 4 ml 6-carotene + vitamin E in the third week of flushing, respectively. The 4-ml treatment of 6-carotene + vitamin E evidently increased the follicle-stimulating hormone level. The 2-ml treatment of 6-carotene + vitamin E increased the triglyceride concentration in the serum. Body condition score, offspring number, and biochemical parameters (cholesterol, phosphorus, calcium, magnesium, aspartate aminotransferase, beta hydroxyl butyric acid, total protein, and glucose) were not affected by any levels of 6-carotene + vitamin E administration. These findings indicate the positive role of 6-carotene + vitamin E administration on pregnancy rate and some blood parameters during flushing.
