Effect of Free Fange Production System on Slower-Growing Broiler Carcass Characteristics and Meat Quality

WOS: 000311195800018The experiment was conducted to study the effect of deep litter system, free-range with fixed housing system and free-range with portable housing system in wheat stubble on carcass characteristics and meat quality of slow-growing broiler chickens. The number of 270 slow-growing Hubbard Isa Red-JA chicks was used in experiment. Number of 12 slow-growing broilers from each production system and totally 36 slow-growing broilers was selected for detection of carcass and meat quality characteristics. Results showed that production system has a significant effect on carcass yield, leg and wing ratios (P0.05). Production system was also not effected in terms of pH, color, protein content, fat, ash, dry matter and water holding capacity of breast meat (P>0.05), but has a significant effect in terms of polyunsaturated fatty acids of breast meat (P0.05). Free-range with fixed housing system has an advantage than other systems in terms of nutrient content, polyunsaturated fatty acids and monounsaturated fatty acid miristoleik acit of breast meat

Effects of egg shell color and storage duration on the external and internal egg quality traits of ATAK-S layer hybrids

WOS: 000388876100015The present study was conducted to investigate the effects of storage duration and egg shell color on external and internal egg quality traits. Eggs were obtained from 29-week--old ATAK-S layer hybrids reared in a traditional cage system. Storage durations were set as 0, 7, 14, 21 and 28 days. Shell color was classified as dark (59.00-67.99); moderate (68.00-70.99) and light (71.00-79.99) using the Delta E values of the eggs. The storage duration significantly affected the egg weight (P <= 0.01), specific gravity (P <= 0.01), breaking strength (P <= 0.01), shell thickness (P <= 0.01), shell weight (P <= 0.01), surface area (P <= 0.01), albumen index (P <= 0.01), yolk index (P <= 0.01), Haugh unit (P <= 0.01), yolk color (P <= 0.05) and albumen pH (P <= 0.01). The egg shell color significantly affected the specific gravity (P <= 0.01), breaking strength (P <= 0.01), shell thickness (P <= 0.01), shell weight (P <= 0.01), albumen pH (P <= 0.05) and albumen blood-meat spots (P <= 0.05). The current findings revealed that the eggs should be transported to consumers as soon as possible, and further studies should be performed to darken egg shell colors. It was concluded that newly laid dark colored eggs had the best quality.Gaziosmanpasa University Scientific Research Projects Department in Turkey [2009/65]This project (Project no: 2009/65) was supported by the Gaziosmanpasa University Scientific Research Projects Department in Turkey

Comparison of the Growth Performance and Carcass Characteristics of Two Slow-Growing Broiler Genotypes Fed Diets Supplemented with Dry Oregano (Origanum vulgare L.) or Lemon Balm (Melissa officinalis L.) Leaves under the Organic System

WOS: 000328083200008This study was conducted to determine the growth performance and carcass characteristics of two slow-growing broiler genotypes (Hubbard S757 and Hubbard Grey Barred JA) fed diets supplemented with dry oregano (Origanum vulgare L. or lemon balm leaves (Melissa officinalis L.) as growth promoter source under an organic housing system. In this study 240 chicks (mixed-sex) were allocated randomly into 4 experimental groups according to a 2 x 2 factorial arrangement for 2 broiler genotypes and 2 diets. The effects of dry herb leaves and genotype x herb leaves interaction on studied parameters were not significant at all weeks of age (P>0.05), except neck (%). Body weight, body weight gain, feed efficiency, carcass weight and yield, leg weight and yield, breast weight and yield, back weight and yield, edible giblets weight and yield of Hubbard S757 genotype were higher (P<0.05) than those of Hubbard Grey Barred JA genotype. The female breast (P<0.01) and edible giblets yield (P<0.05) were superior to those of males. These results show that herb leaves used as a growth promoter source under organic housing system did not affect the studied parameters and that in terms of these parameters, and subsequent Hubbard S757 genotype were superior to Hubbard Grey Barred JA genotype.Cumhuriyet University [ENF-003]This study was supported by the Research Fund of Cumhuriyet University (Project No: ENF-003

Effect of Different Housing Systems on Production and Blood Profile of Slow-Growing Broilers

WOS: 000354410800011Present study was conducted to investigate the effects of deep litter system, free-range with fixed housing system and free-range with portable housing system in wheat stubble on performance, internal organ weights, blood parameters and tonic immobility of slow-growing broilers. A total of 270 Hubbard Isa Red-JA chicks were used in experiments. The experiment lasted for 61 days. Results showed that the body weight on 21(st), 28(th), 35(th) and 42(th) days of birds from free-range with portable housing system was significantly lower than of those kept in deep litter and free range with fixed housing system. The viability of broilers in free-range with portable housing system was lower than broilers in free-range with fixed housing and deep litter system in the days of 14-42 and 14-61, while there were not any differences between housing systems in days of 43-61. Housing systems had no significant effect on feed conversion ratio and internal organ weight. There were no significant differences in tonic immobility durations of housing systems and some blood parameters, except hematocrit values. In conclusion, the body weight in free-range with portable housing system was significantly lower until 42nd day of the experiment, but this difference was disappeared during the rest of rearing period. It could be concluded that rural producer can be involved in broiler production after wheat harvesting.Commission Gaziosmanpasa University Scientific Research Projects [2010/75]This project was supported by the Commission Gaziosmanpasa University Scientific Research Projects (Project No: 2010/75

The welfare of slow growing broiler genotypes reared in organic system

WOS: 000368569700009This study study was conducted to compare welfare indicators and some serum biochemical parameters of two different slow-growing genotypes (Hubbard S757; S757 and Hubbard Grey Barred JA; GB-JA) under organic housing system. A total of 240 day-old chicks were allocated randomly into 2 experimental group with 6 replicates and 20 chicks was reared in each replicate. The tonic immobility was a significant difference between genotypes and sex at 10 and 14 weeks, respectively (P 0.05) in genotypes and sex. The effect of sex was significant for width of tarsometatarsus at the joint with tibiotarsus; males had greater fluctuating and relativite asymmetry than females (P < 0.05). There were positively correlations between fluctuating and relative asimetry values of the third phalanx of the mid toe length and the fourth phalanx of the outer toe length from specific feet trait measurements. Serum cholesterol and uric acid had significant differences between genotypes (P < 0.01). Cholesterol levels was significantly (P < 0.01) higher in male than in female slow-growing broiler. It is concluded that slow-growing genotypes and sex had no effect on measures of welfare, such as the fluctuating asymmetry, relativite asymmetry, tonic immobility and rectal temperatures.Research Fund of Cumhuriyet University [ENF-003]This study was supported by the Research Fund of Cumhuriyet University (Project No: ENF-003), which was approved by the local Ethical Committee of Cumhuriyet University for Experimental Animals

EFFECT OF DISTANCE FROM THE ROADWAY ON HEAVY METAL CONTENT AND EGG QUALITY OF VILLAGE LAYING HEN'S EGG ALONG ROADSIDES OF TOKAT-TURHAL, TURKEY

WOS: 000323211700020In this study, the heavy metal contents and egg quality characteristics of chicken eggs was studied. The eggs have been collected at distances of 0-100 (Distance A), 100-200 (Distance B) and 200-300 m (Distance C) away from the edge of Tokat-Turhal road. The distance from roadway had no significant effect on egg Cu and Mn contents (P>0.05), although a significant effect on egg Cd and Pb content (P 0.05). Eggs obtained from distance A and B had significantly higher weight than obtained from distance C (P<0.05). Egg obtained from distance B had significantly lower egg shell colour scales than those of the other distances (P<0.01). And, egg yolk colour was showed a significant variation among the distances away from the roadway, and the highest yolk colour value was detected in distance B (P<0.05). Depending on obtained results, it can be concluded that the egg heavy metal concentrations exceeded background levels for hen eggs. Therefore, consumers should be aware of the possible health risks related by the use of these eggs which has obtained from side of road

Comparison of Growth Curves by Growth Models in Slow-Growing Chicken Genotypes Raised the Organic System

WOS: 000335984300010Two hundred and forty slow-growing chickens consisting of equal numbers of Hubbard S757 (S757) and Hubbard Grey Barred JA (GB-JA) strains were utilized for the investigation in organics system and were used to estimate growth curve in Gompertz and Logistic model. The asymptotic weights for GB-JA and S757 genotype female; male in the Gompertz model were estimated 3725.34 g; 6109.60 g and 4876.10 g; 6496.47 g and same parameter were found in Logistic model 2133.33 g; 2906.35 g and 2790.37 g; 3635.00 g respectively. The Gompertz model was higher estimate than Logistic model for the asymptotic weights parameter. The instantaneous growth rate for GB-JA and S757 genotype female; male in the Gompertz model were estimated 0.1424; 0.1288 and 0.1525; 0.1495 and same parameter values were found in Logistic model 0.3753; 0.3734 and 0.3873; 0.3949 respectively. Significant difference was observed for the instantaneous growth rate parameter between GB-JA and S757 genotypes in each of models. According to the results of goodness of fit in Gompertz and Logistic growth curve models, the coefficient of determination (R-2) and adjusted coefficient of determination (adj. R-2) were detected above 0.996 in boot models for two genotype broilers. The highest value of R-2 and adj. R-2 were obtained from the Logistic model in GB-JA. The two models were all fitted the growth curves of slow-growing chicken genotypes in organic system very well, and the fitting degrees R-2 were all above 0.998; for the two models; however Logistic model was the best (0.999%). c 2014 Friends Science PublishersCumhuriyet University [ENF-003]This study was supported by the Research Fund of Cumhuriyet University (Project No: ENF-003)

Identification of Epileptic EEG Signals Using Convolutional Neural Networks

Epilepsy is one of the chronic neurological disorders that is characterized by a sudden burst of excess electricity in the brain. This abnormality appears as a seizure, the detection of which is an important research topic. An important tool used to study brain activity features, neurological disorders and particularly epileptic seizures, is known as electroencephalography (EEG). The visual inspection of epileptic abnormalities in EEG signals by neurologists is time-consuming. Different scientific approaches have been used to accurately detect epileptic seizures from EEG signals, and most of those approaches have obtained good performance. In this study, deep learning based on convolutional neural networks (CNN) was considered to increase the performance of the identification system of epileptic seizures. We applied a cross-validation technique in the design phase of the system. For efficiency, comparative results between other machine-learning approaches and deep CNNs have been obtained. The experiments were performed using standard datasets. The results obtained indicate the efficiency of using CNN in the detection of epilepsy

Comparison of Growth Curves of Broiler under Different Stocking Densities by Gompertz Model

WOS: 000321751900019The knowledge of the growth curve in poultry science is very useful for describing growth kinetics and setting commercial management procedures. The objective of this research was to fit the Gompertz growth curve from hatching weights to 42 d-old weights of broilers in 3 stocking density groups. A total of 284 Ross 308 broilers randomly divided into 3 stocking density groups (9, 13 and 17 birds/m(2)) in this experiment. All birds were weighted weekly. The asymptotic weight (A) of broiler chickens for 9, 13 and 17 bird/m(2) stocking density groups were 4198.46, 3807.45 and 3999.92 g, respectively (P<0.05). The growth rates (K) of broiler chickens for 9, 13 and 17 bird/m(2) stocking density groups were 0.055, 0.058 and 0.052, respectively (P<0.01). The coefficient of determination for all stocking density groups were 0.998, 0.997 and 0.996, respectively (P<0.05). Moreover, the mean square error (MSE) value was lowest for 9 bird/m(2) group (P<0.05). The current study suggested that stocking density of 9 bird/m(2) was better for the broiler growth of the different stocking densities on the base of mature live weight (A), coefficient of determination (R-2) and mean square error (MSE)

THE EFFECT OF DRY CAPER (Capparis spinosa) FRUIT ON EGG PRODUCTION AND QUALITY CHARACTERISTICS OF LAYING HENS

WOS: 000334022300028This study was conducted to determine the effect of increasing dietary inclusion of dry Caper (Capparis spinosa) fruit (DCF) on egg production and quality characteristics of laying hens between 20 and 32 weeks of age. Four groups of commercial hens (ATAK-S) were fed with diets containing 0, 5, 10 and 15 g DCF/kg. The results showed that final body weight, feed intake, shape index (SI) and morning hen-day egg yield were influenced by dietary supplementation of DCF (P0.05) during the entire experiment. The lightness (L*) and redness (a*) values for egg shell color were similar (P>0.05) in the DCL supplemented groups as compared to the control group. The yellowness (b*), Hue angle (H), chroma (C*) and Delta E* values were lower (P<0.05) in 15 g DFC/kg group when compared with the control. Trolox equivalent antioxidant capacity (TEAC), ferric reducing antioxidant power (FRAP) and total phenolics amount of DCF were 43.75 +/- 0.680 mmol trolox/kg, 60.03 +/- 3.710 mmol TEAC/kg and 3.16 +/- 0.060 g gallic acid equivalents (GAE)/kg, respectively. Based on the results from the current study, the dietary supplementation with dry DCF had adverse effects on productivity performance traits and egg quality
