Çalışmada, basit tesadüfî örnekleme yöntemiyle seçilen köylerde 2017-2018 yılları arasında köy tavukçuluğu yapan toplam 8 ilçede belirlenen 47 köyde işletme sahipleri ile yüz yüze yapılan anketlerden elde edilen veriler analiz edilmiştir. Araştırma bulgularına göre; işletme sahiplerinin aylık gelirleri ortalaması 663,52 TL olduğu, ailede yaşayan birey sayısının ortalama 11.8 kişi olduğu sonucu belirlenmiştir. İşletmelerin tamamında kanatlı yetiştiriciliği yapıldığı ve kanatlı hayvan sayısının ortalama 82 adet olduğu tespit edilmiştir. Ekonomik getiriden dolayı köy tavukçuluğu yapan yetiştirici oranı %5.7 olarak saptanmıştır. Kanatlı hayvan sayısının ilçeler itibariyle değiştiği ve ortalamalar arasındaki farkların istatistiki olarak önemli olduğu belirlenmiştir (P<0.05). İşletmelerin tamamında hastalık görüldüğü ve tavuklara aşı yapılarak hastalıklara karşı önlem alındığı tespit edilmiştir. Köy tavukçuluğu yetiştiriciliği yapmayan yetiştiricilerin (%3) tamamının hastalıklardan dolayı köy tavukçuluğu yetiştiriciliğinden vazgeçtikleri sonucu saptanmıştır. Yetiştiricilerin %61'i hastalıkları, %23'ü desteklemeleri, %11'i yem maliyetini ve %5'i ise pazarlamayı sorun olarak gördüklerini belirtmişlerdir. Sonuç olarak; köy tavukçuluğunu ekonomik getirisinden dolayı yapmayı hedefleyen dinamik ve eğitimli bir üretici kitlesinin ilgili kurum ve kuruluşlarca teşvik edilmesi tavukçuluğun gelişmesine ivme kazandıracaktır. Özellikle hastalıklar, destek ve teşvikler, yem maliyeti ve pazarlama konularında yetiştiricilerin sorunlarının çözümü için gerekli strateji ve politikaların geliştirilmesi gereklidir.

Two hundred eighty-eight chicks (Ross 308) randomly distributed into eight groups with three replicates in each treatment. First group was fed the basal diet, without any plant supplement, as control group, while the 2 nd and 3 rd groups were fed the same diet with thyme (5 and 10 g/kg, respectively), the 4 th and 5 th groups were fed diets with Adiantum (3 and 5 g/kg, respectively) and the 6 th and 7 th groups were fed diets supplemented with rosemary at 5 and 10 g/kg, respectively, the combination of plants (7.5 g/kg of thyme and 7.5 g/kg of rosemary and 4 g/kg of adiantum) added to the basal diet of group 8 th. The active compounds of the three plants were analyzed by Gas Chromatography/Mass Spectrometry. Live body weight was measured at weekly intervals. At the end of the experiment, the following traits were measured: carcass traits, internal organ, lymphoid organs and meat color. The obtained results summarized as follows: Fourteen, Fifteen and Twenty-one compounds were identified in the Thyme, Adiantum and Rosemary samples, respectively, and the major compounds were carvacrol (60.77%), gamma-terpinene (41.23%) and α-Pinene (51.87%), respectively. Overall, there is a significant effect of medicinal plants on live body weight in both genders, in which the male chicks in the 4 th group and female chicks in 7 th group had significantly higher live body weight. Regarding male chickens, T2, T3 and T8 groups have significantly higher carcass yield, also each of dressing percentage, breast, legs and wings were higher in T3 group. Furthermore, neck and back weight was higher in T3 group in both genders. It can be concluded that the supplementation of medicinal plants to broiler´s diet had a beneficial effect on most of broiler performance, particularly in male chickens that fed T3 group (Thyme 5g/kg).

To achieve this goal, a total of 600 0-day-old quail chicks were used. The birds were divided into 5 groups with 3 replicates. The 1 st , 2 nd , 3 rd , 4 th and 5 th groups received 0, 5, 10, 15 and 20% lentil byproduct, respectively. All the diets were prepared as isonitrogenous and isocaloric. As a result of this study, the highest live body weights of quails as Laudadio mixed gender were observed in the 3 rd (195.5 g) and 5 th (195.3 g) groups at the end of the study, however the differences between the control and treatment groups were not significant (p>0.05). Similar results were observed in the carcass traits, as well. The best feed conversion ratio (FCR) was noted in both the 2 nd and 3 rd groups as 3.04 and it was significantly (p<0.05) different than in the control and other treatment groups. The least feed intake (FI) was observed in the 2 nd group. The highest and the lowest egg yield percentages were in the 3 rd (90.78 %) and 5 th (66.57 %) groups, and differences were significant (p<0.01). Linear increments were observed in the yolk color when LP increased in the diet. As a result, it could be concluded that lentil by product could be added into quail diets up to 15% with no negative effect on live body weight (BW) and carcass traits and to get better yolk color.

To accomplish this goal, a total of 210 day old big-6 turkey chicks were used. The birds were divided into 7 seven groups with 3 replicates. The 1 st , 2 nd , 3 rd , 4 th , 5 th , 6 th and 7 th groups received 0, 5, 10, 15, 20, 25 and 30 % lentil by product, respectively. All the diets were made as izonitrojenic and izocaloric. The highest live body weights of males and females were observed in the control group at the end of the 15 th week, which was the time of slaughtering of females, however the differences between the control and the 2 nd , 3 rd and 4 th groups were not significant (p>0.05). The same differences continued for males at the end of the 17 th wk of age, which was the time of slaughtering of males. Similar results were observed in carcass traits, as well. The best FCR was noted in the control group and it was significantly (p<0.05) different than in the treatment groups. The lowest and highest feed intake was observed in the 7 th and 3 rd groups. No significant differences were observed between control and all treatment groups. As a result, it could be said that lentil by product could be added into turkey diets up to 15% with no negative effect on live body weight and carcass traits because there was no significant differences between control and treatment groups (5, 10,15 % LP).

Two hundred sixteen chicks were divided into four groups: control (no antibiotic or thyme extracts (I), fl avomycin (II), thyme oil extract (III) and thyme water extract (IV). Groups II and III received 1 g/kg fl avomycin as an antibiotic and 2.5 ml/kg thyme oil extract, respectively. Birds in group IV received 100 ml/l of thyme water extract in their drinking water. There were no signifi cant differences in liveweight between the treatment groups, but feed intake differed (P<0.01) at 0-5 weeks of age. Results showed that thyme extracts decreased feed consumption during the experiment. Similarly, the survival rate differed signifi cantly (P<0.01) between groups; the lowest was in antibiotic group. The levels of plasma cholesterol, triglyceride, high density lipoprotein, very low density lipoprotein and alkaline phosphates were similar in the four treatments. The highest rate of total oxidant status and total antioxidant response were found in group III, the lowest rate of DNA damage in the thyme oil (III) and thyme water extracts (IV) groups. It was concluded that supplementing thyme extract products in the diet of quails at the doses studied does not lead to a negative effect on the growth performance of the birds. Supplemented antibiotic caused an elevation in the oxidative stress index and in DNA damage.

To achieve this goal, the live weight of male and female turkeys (Large White) reared for 0-18 weeks were used. Logistic, Gompertz, Von Bertalanffy, and Gauss were used to determine the best model for the turkeys. In comparison of the models, values of Coefficient of Determination (R 2), Mean Squares of Error (MSE) and Model Efficiency (ME) were used. In Von Bertalanffy model, the coefficient of determinations for males and females were found as 0.9974 and 0.99915 in intensive system and 0.9794 and 0.9804 in Free-Range system, respectively. As a result of this study, because the highest R 2 and the lowest MSE were observed in Von Bertalanffy model, it was the best among the models to identify growth curve of the turkeys.

To accomplish this aims, totally 288 d old large white turkey chicks (144 in each sex) were used. Beaks of 77 male and female poults were trimmed when 8 d old with an electrical beak trimmer. The birds were fed by commercial turkey rasion. Experiment was designed as 2 × 2 × 2 factorial arrangement with 3 replications in each group. Beak trimming and stocking density did not affect live weight, carcass composition and its components. The higher LW and carcass weight observed in trimmed groups. As expected, male birds are heavier than female, and carcass percentage (CP) would be adverse. However, in this study, CP of male was higher in trimmed, in 0.25 m(2)/bird. (D) × sex (S) interaction had an effect on both CP and thigh weights (p<0.05). Significantly D × ...

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.

Two hundred eighty-eight chicks (Ross 308) randomly distributed into eight groups with three replicates in each treatment. First group was fed the basal diet, without any plant supplement, as control group, while the 2 nd and 3 rd groups were fed the same diet with thyme (5 and 10 g/kg, respectively), the 4 th and 5 th groups were fed diets with Adiantum (3 and 5 g/kg, respectively) and the 6 th and 7 th groups were fed diets supplemented with rosemary at 5 and 10 g/kg, respectively, the combination of plants (7.5 g/kg of thyme and 7.5 g/kg of rosemary and 4 g/kg of adiantum) added to the basal diet of group 8 th. The active compounds of the three plants were analyzed by Gas Chromatography/Mass Spectrometry. Live body weight was measured at weekly intervals. At the end of the experiment, the following traits were measured: carcass traits, internal organ, lymphoid organs and meat color. The obtained results summarized as follows: Fourteen, Fifteen and Twenty-one compounds were identified in the Thyme, Adiantum and Rosemary samples, respectively, and the major compounds were carvacrol (60.77%), gamma-terpinene (41.23%) and α-Pinene (51.87%), respectively. Overall, there is a significant effect of medicinal plants on live body weight in both genders, in which the male chicks in the 4 th group and female chicks in 7 th group had significantly higher live body weight. Regarding male chickens, T2, T3 and T8 groups have significantly higher carcass yield, also each of dressing percentage, breast, legs and wings were higher in T3 group. Furthermore, neck and back weight was higher in T3 group in both genders. It can be concluded that the supplementation of medicinal plants to broiler´s diet had a beneficial effect on most of broiler performance, particularly in male chickens that fed T3 group (Thyme 5g/kg).

Almost every kind of the fish can accumulate Hg. Hg-induced peculiarities of cellular malfunction could be used as adequate biomarker to estimate the contamination risk in polluted aquatic ecosystems. The brain cells are high susceptible to the Hg compounds cytotoxicity. Various Hg species have different harmful effects on both structure and function of the brain cells. Neurotoxicity of inorganic Hg remains discussable and studied restrictedly. In this study, we have studied the role of RPA1 and p53 proteins in brain cell response to sublehtal (25% LD50 and 50% LD50) doses of inorganic Hg in rainbow trout (Oncorhynchus mykiss). LD50 value of Hg chloride in presented study was determined as 551 µg/L relate to 96 hours exposure. Two sublethal doses were used in the exposure rainbow trout at 2 and 7 days. The treatment with Hg chloride induced in fish brain dose-dependent increase in ROS level as well as t...

To achieve this goal, a total of 600 0-day-old quail chicks were used. The birds were divided into 5 groups with 3 replicates. The 1 st , 2 nd , 3 rd , 4 th and 5 th groups received 0, 5, 10, 15 and 20% lentil byproduct, respectively. All the diets were prepared as isonitrogenous and isocaloric. As a result of this study, the highest live body weights of quails as Laudadio mixed gender were observed in the 3 rd (195.5 g) and 5 th (195.3 g) groups at the end of the study, however the differences between the control and treatment groups were not significant (p>0.05). Similar results were observed in the carcass traits, as well. The best feed conversion ratio (FCR) was noted in both the 2 nd and 3 rd groups as 3.04 and it was significantly (p<0.05) different than in the control and other treatment groups. The least feed intake (FI) was observed in the 2 nd group. The highest and the lowest egg yield percentages were in the 3 rd (90.78 %) and 5 th (66.57 %) groups, and differences were significant (p<0.01). Linear increments were observed in the yolk color when LP increased in the diet. As a result, it could be concluded that lentil by product could be added into quail diets up to 15% with no negative effect on live body weight (BW) and carcass traits and to get better yolk color.

To accomplish this goal, a total of 210 day old big-6 turkey chicks were used. The birds were divided into 7 seven groups with 3 replicates. The 1 st , 2 nd , 3 rd , 4 th , 5 th , 6 th and 7 th groups received 0, 5, 10, 15, 20, 25 and 30 % lentil by product, respectively. All the diets were made as izonitrojenic and izocaloric. The highest live body weights of males and females were observed in the control group at the end of the 15 th week, which was the time of slaughtering of females, however the differences between the control and the 2 nd , 3 rd and 4 th groups were not significant (p>0.05). The same differences continued for males at the end of the 17 th wk of age, which was the time of slaughtering of males. Similar results were observed in carcass traits, as well. The best FCR was noted in the control group and it was significantly (p<0.05) different than in the treatment groups. The lowest and highest feed intake was observed in the 7 th and 3 rd groups. No significant differences were observed between control and all treatment groups. As a result, it could be said that lentil by product could be added into turkey diets up to 15% with no negative effect on live body weight and carcass traits because there was no significant differences between control and treatment groups (5, 10,15 % LP).

Two hundred sixteen chicks were divided into four groups: control (no antibiotic or thyme extracts (I), fl avomycin (II), thyme oil extract (III) and thyme water extract (IV). Groups II and III received 1 g/kg fl avomycin as an antibiotic and 2.5 ml/kg thyme oil extract, respectively. Birds in group IV received 100 ml/l of thyme water extract in their drinking water. There were no signifi cant differences in liveweight between the treatment groups, but feed intake differed (P<0.01) at 0-5 weeks of age. Results showed that thyme extracts decreased feed consumption during the experiment. Similarly, the survival rate differed signifi cantly (P<0.01) between groups; the lowest was in antibiotic group. The levels of plasma cholesterol, triglyceride, high density lipoprotein, very low density lipoprotein and alkaline phosphates were similar in the four treatments. The highest rate of total oxidant status and total antioxidant response were found in group III, the lowest rate of DNA damage in the thyme oil (III) and thyme water extracts (IV) groups. It was concluded that supplementing thyme extract products in the diet of quails at the doses studied does not lead to a negative effect on the growth performance of the birds. Supplemented antibiotic caused an elevation in the oxidative stress index and in DNA damage.

To achieve this goal, the live weight of male and female turkeys (Large White) reared for 0-18 weeks were used. Logistic, Gompertz, Von Bertalanffy, and Gauss were used to determine the best model for the turkeys. In comparison of the models, values of Coefficient of Determination (R 2), Mean Squares of Error (MSE) and Model Efficiency (ME) were used. In Von Bertalanffy model, the coefficient of determinations for males and females were found as 0.9974 and 0.99915 in intensive system and 0.9794 and 0.9804 in Free-Range system, respectively. As a result of this study, because the highest R 2 and the lowest MSE were observed in Von Bertalanffy model, it was the best among the models to identify growth curve of the turkeys.

To accomplish this aims, totally 288 d old large white turkey chicks (144 in each sex) were used. Beaks of 77 male and female poults were trimmed when 8 d old with an electrical beak trimmer. The birds were fed by commercial turkey rasion. Experiment was designed as 2 × 2 × 2 factorial arrangement with 3 replications in each group. Beak trimming and stocking density did not affect live weight, carcass composition and its components. The higher LW and carcass weight observed in trimmed groups. As expected, male birds are heavier than female, and carcass percentage (CP) would be adverse. However, in this study, CP of male was higher in trimmed, in 0.25 m(2)/bird. (D) × sex (S) interaction had an effect on both CP and thigh weights (p<0.05). Significantly D × ...

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.
