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.
Effects of Adding Aluminum Sulfate To Different Litters on Selected Trace Elements and Vitamins Concentrations in Broiler
(Academic Journals, 2008) Celen, Mehmet Fatih; Kozat, Suleyman; Ekin, Suat; Yoruk, Brahim Hakki; Alki, Emine
The objective of this study was to determine the effects of adding aluminum sulfate to different litters on blood plasma concentrations of some principal microelements and some vitamins in broilers. In this experiment, 645 day old Ross 308 broiler chicks were randomly divided into 4 litter group (straw, sawdust, alum treated-straw and alum treated-sawdust). At the end of the experiment 10 birds (5 male + 5 female) from each of the groups were slaughtered by severing the jugular vein and sampled by taking the blood. Blood plasma concentrations of vitamin A (retinol), vitamin E ( -tocoferol), Co, Zn and Cu were determined. Body weight measured at 6 week of age. Blood plasma Zn, Cu concentrations did not differ significantly (P < 0.05) among treatments, but the broilers reared in the control straw group showed lower Co concentration. The vitamin A and E levels in the serum of the broilers in the straw and saw dust groups were slightly lower than the other groups. The body weight of female in the alum treated groups at the end of the experiment was significantly higher than control groups. The body weight of male in the alum treated-sawdust group at the end of the experiment was significantly higher than the other groups. It could be concluded that amending aluminum sulfate to different litters adversely affected blood plasma concentrations and body weight of broiler.
Effects of Alum Treatment of Two Litter Materials on Growth Performance of Broiler Chicken
(Academic Journals, 2009) Alkis, Emine; Celen, Mehmet Fatih
The objective of this study was to evaluate the effects of aluminum sulfate (alum) amendment to 2 litter materials on broiler growth performances. 645 newly born broiler chicks were randomly allocated into 4 litter groups (control straw, control sawdust, alum treated straw and alum treated sawdust). Feed and water were provided ad libitum throughout the 42 day experimental period. Chicks were placed in floor pens at a final stocking density of 12 bird/m(2). At the end of the experiment, live weights of control straw, control sawdust, alum treated straw and alum treated sawdust groups in females were 2173.46, 2183.43, 2365.74, 2383.27 g respectively and in males were 2566.69, 2503.43, 2578.68, 2675.46 g respectively. Alum provided benefits broiler weight gain when compared to the untreated control. FCR of control straw, control sawdust, alum treated straw and alum treated sawdust groups were 1.76, 1.72, 1.86 and 1.77 respectively. Livability of control straw, control sawdust, alum treated straw and alum treated sawdust groups in females were 88.59, 90.55, 83.97 and 88.13% respectively and in males 91.73, 96.51, 90.64 and 90.79% respectively. Livability (%) was not different (P > 0.05) among treatments. The weight of breast (g), neck (g), gizzard (g), heart (g), back (g) and fat (g) did not differ among groups. There were significantly different in live weight and weight of carcass (g) among groups. Thigh (g), wing (g), liver (g) were significantly different among groups and sexes (P < 0.05).
The Effects of Broiler Breeder Age and Extra Oxygen Addition Into Incubator at High Altitude (1700 M) on Hatching Results and Subsequent Performance in Broilers
(Medwell online, 2009) Celen, Mehmet Fatih; Yildirim, Iskender; Parlat, Sinan S.; Alkis, Emine
Breeder age and oxygen concentrations from 15-21 days of incubation were tested as factors determining on hatching and subsequent performances of broiler at high altitude. Eggs produced by breeders of 31 or 55 weeks of age. All eggs from 2 breeder ages were distributed randomly into 2 hatching cabinets, which were operated at different oxygen concentrations. The 1st cabinet was oxygenated at 25%, whereas, no oxygen added to the 2nd cabinet and called control group. Fertile hatchability was affected by the Oxygen supplementation and flock age interaction. The highest fertile hatchability was obtained when the breeders were 55 weeks of age with adding oxygen but not in breeders at 31 weeks of age. The fertile hatchability was decreased at 55 weeks of age in control group. The late embryo mortality was significantly depressed in embryos from breeders at 55 weeks of age when oxygen added. Chick weights of hatch, 1st and 3rd weeks among groups were not affected by interaction between Oxygen. supplementation and flock age. Feed conversion ratio and mortality were enhanced in chicks obtained from breeders 55 weeks of age when oxygen added. It is concluded that oxygen supplement to the incubators at high altitude improves the fertile hatchability, feed conversion ratio and decreases mortality of chicks obtained from breeder of 55 weeks of age.
