Comparison of Normal and Pse Turkey Breast Meat for Chemical Composition, Ph, Color, Myoglobin, and Drip Loss
(Revista Brasileira Zootecnia Brazilian Journal Animal Sci, 2016) Celen, Mehmet Fatih; Sogut, Bunyamin; Zorba, Omer; Demirulus, Husrev; Tekeli, Ahmet
The objective of this investigation was to determine the differences between normal and PSE (pale, soft, exudative) turkey breast meat in terms of chemical composition, pH, color, myoglobin, and drip loss. Pale and normal skinless, boneless turkey breast fillets were taken from a poultry slaughterhouse in Van/Turkey at about 2-3 h postmortem. Spectrocolorimetry (CIE L*a*b*), pH, protein, ash, dry matter, lipid, myoglobin, and drip loss were measured in normal and pale color turkey breast muscle. The normal breast meat had significantly lower L*, a*, and b* values in comparison with the pale breast meat. Myoglobin concentration and pH were significantly higher in the normal breast meat compared with that of the pale breast meat. Protein content was found to be significantly lower for the pale group compared with the normal group. No significant difference was found in ash, dry matter, and total lipid content between normal and pale breast meat. Drip loss was significantly affected by breast meat color groups at days 1, 2, 3, and 4 postmortem. Pale, soft, exudative turkey breast meat can lead to differences in the chemical composition and shelf life of the product.

(Taylor & Francis Ltd, 2008) Cetin, Mehmet; Yurtseven, Sabri; Sengul, Turgay; Sogut, Bunyamin
This study was conducted to evaluate the effect of different doses of black seed extract on fattening performance, some blood parameters, oxidative stress and DNA damage of partridges. Chicks were divided in four groups: I group (control) received 0.1% flavomycin, treatment groups II, III and IV received 2.5, 5 and 7.5 ml/kg black seed extract, respectively. Feed consumption was reduced linearly by increasing doses of black seed extract in 0 to 12 weeks of age (P<0.01). Mortality rates of the treatment groups were lower than control group (P<0.05). Alkaline phosphate levels (ALP) was affected by black seed extract (P<0.05). The results also showed that black seed extract decreased DNA damage linearly and significantly (P<0.01).

(Medwell online, 2009) Kalpak, Osman; Sogut, Bunyamin
This study was conducted to investigate effect of feed restriction (80 and 70% of ad libitum consumption) on growth performance of Japanese quail. To achieve this goal, I day old 363 Japanese quail were divided into 3 groups, randomly; The 1st, 2nd and 3rd groups were control, 20% feed restricted and 30% feed restricted, respectively. All chicks were weighed by 0,01 g sensitivity; leg banded by tape and reared on 5 cm deep wood shavings. They were provided ad libitum access to a commercial starter breeder diet containing 28% CP with 2800 kcal ME kg(-1) for 14 days and provided commercial finisher breeder diet containing 24% CP with 3000 kcal ME kg(-1) for 28 days. Feed restriction was started at the end of 14 days after hatching and lasted 2 weeks. During the trail control group had ad libitum access to the feed but 2nd and 3rd group had 80 and 70% of control group. Birds were weighed individually every week and supplied water for ad libitum consumption until end of the trail. Analysis of variance was carried out on the data using the General Linear Model procedure of base SAS software. T-test was used to compare differences among the treatments. At the end of 14 days after hatching, average body weights of group 1, 2 and 3 were 60.50 +/- 1.17, 62.12 +/- 1.18 and 61.93 +/- 1.20 g (p>0.05) for males and 62.80 +/- 1.10, 61.32 +/- 1.07 and 63.2 +/- 1.18 g (p>0.05) for females, respectively. Feed restriction had negative effect on quail growing at the end of 4th week after hatching, which was last week of feed restriction practice. At this week, average body weights for group 1, 2 and 3 were 134.36 +/- 2.18, 125.34 +/- 2.19 and 124.85 +/- 2.18 g (p<0.01) for males and 135.00 +/- 2.25, 124.17 +/- 2.29 and 130.76 +/- 2.49 g (p<0.01) for females, respectively. At the end of trial, average body weights of group 1, 2 and 3 were 164.18 +/- 2.89,166.74 +/- 2.91 and 162.17 +/- 2.97 g for males and 184.92 +/- 2.92, 182.47 +/- 2.85 and 186.39 +/- 3.12 g for females (p>0.05), respectively. As it was seen, body weights of feed restricted quail were significantly lower than control group during trail. Two weeks after feed restriction ended, however, body weights were no longer different. As a result, the effects of feed restriction during growing period for quail in this study were similar to those observed in chickens. These data indicate that by 30% feed restriction can be practiced for 2 weeks during growing period of quail.
The Effects of Diet Supplemented With the Black Cumin (Nigella Sativa L.) Upon Immune Potential and Antioxidant Marker Enzymes and Lipid Peroxidation in Broiler Chicks
(Medwell online, 2008) Sogut, Bunyamin; Celik, Ismail; Tuluce, Yasin
This study was carried out to investigate whether Nigella saliva (NS) could decrease the lipid peroxidation [Malondialdehyde = MDA], increase the anti-oxidant defence system [Reduced Glutathione (GSH), Catalase (CAT) and Glutathione-S-Tranferase (GST)] and also posses the immunopttential [Adenosine Deaminase (ADA) and Myeloperoxidase (MPO)]. Totally, 100 Ross 308 birds, I day old, were used. Chicks were divided into 4 experimental groups, (control, 3, 5 and 7% containing Nigella saliva) each containing 25 broiler chicks. While, the control group received normal broiler fattening feed, the treatments groups were fed with the feed containing 3, 5 and 7% grinded Nigella saliva seed and all groups fed and watered ad libitum for 6 weeks during experiment. At the end of the 6 weeks experiment, liver samples were taken to measure MDA, GSH, CAT, GST, ADA and MPO. While, treatment with N. saliva decreased the liver MDA content, increased the activities of CAT, GST, ADA and MPO significantly, but increased the level of GSH lightly in comparison to control. It was concluded that N. saliva might be used to potent of antioxidant and immune system and also prevent liver from oxidative stress resulting lipidperoxidation.
The Effects of Varying Dietary Na/K Ratio and Electrolyte Balance of Diets on Growth, Blood Gases, Hematological Variables, Ionized Calcium and Carcass Traits in Broiler Chickens
(Kafkas Univ, veteriner Fakultesi dergisi, 2011) Nursoy, Huseyin; Sogut, Bunyamin; Tasal, Turkan; Aldemir, Resit; Kaplan, Oktay; Altacli, Selcuk
The effects of 12 different diets which regulated 0.1-0.7 mol Na/K ratio and 176-422 mEq/kg Dietary Electrolyte Balance, DEB, (Na+K-Cl) were investigated on growth, blood gases, hematological variables, biochemical parameters and carcass traits in broiler chickens. Two-day old Ross-308 male chicks (n=180) having individual thirty replicates for 6 groups were used and the study lasted 42 days in the experiment. The S group diet was based on corn and soybean meal and 0.25% salt. This group diet was accomplished by adding 1-0.5% NH4Cl as A1 and A2 of anionic groups and 0.5-1-1.5% NaHCO3 as C1, C2 and C3 of cationic groups in starter and grower phases, respectively. Increasing Na/K and DEB of the diets had no effect on live weight, body weight gain and feed per gain in 0-42 days (P>0.05). Blood pH quantitatively increased in S, C1 and C2 groups (P<0.05). A1, A2 and S groups of pO(2) levels were higher than those of cationic groups (P<0.05), (R-2=0.59). The values of HCO3-, HCO3std, TCO2, BEecf, Be(b), Hct and THbc were lower anionic groups than cationic groups (P<0.05), (R-2=0.63-0.82). SO2c level was the lowest in C1 group (P<0.05). Anion gaps of the broilers were calculated as 7.97-20.84 mEq/l. Ionized calcium was quantitatively the highest in A1 group. Hot carcass and abdominal fat were not affected by the experimental diets with varying Na/K and DEB (P>0.05). Based on the results of this study, anionic diet such as A1 or 0.1 of Na/K ratio and 212 mEq/kg of DEB could be fed for broilers in case of insufficient Ca. In normal case, it is concluded that C1 and C2 of diets or 0.3-0.5 of Na/K ratios and 259-344 mEq/kg of DEB were appropriate for broilers.
