OZONLU, REÇİNELİ, KLORLU, SELESTİT TAŞLI VE DOĞAL KAYNAK SULARININ BILDIRCINLARDA PERFORMANS, OKSİDATİF STRES VE KARKAS PARAMETRELERİ ÜZERİNE ETKİLERİ SEREN, Burak ÖZET Bu çalışma, Ozonlu (Hazır ticari pet su), Reçineli (100 g çam çırası/4,5 l şehir şebeke suyu), Klorlu (Şehir şebeke suyu), Selestit Taşlı (200 g/4,5 l şehir şebeke suyu) ve Doğal Kaynak Suları (Kadın-Çocuk Hastanesi civarındaki Karlıova Çeşmesi, Bingöl, Türkiye) gibi 5 çeşit suyun bıldırcınlarda performans, oksidatif stres ve karkas parametrelerine etkilerini tespit etmek amacıyla yapıldı. Denemede 150 adet dişi-erkek karışık 3 günlük bıldırcınlar kullanıldı ve her bir su grubunda 30 adet olmak üzere 10 kuş bulunan 3 alt gruba ayrıldı. Deneme 7 hafta sürdürüldü. Deneme boyunca hayvanlara protein oranı %26,14 ve ME 3069 kcal/kg olan tek bir yem ve beş farklı su çeşidi ad libitum olarak verildi. Denemede kullanılan su tiplerinin analizlerinde pH, Ca, Mg, Cl, Elektriksel İletgenlik ve Total Bakteri bakımından istatistiksel farklılıklar gözlendi. Canlı ağırlık, günlük canlı ağırlık artışı ve yem tüketimi Doğal Kaynak Suyu içen bıldırcınlarda en yüksek, Reçineli Su Grubu’nda ise en düşük bulundu (P<0,001). Doğal Kaynak Suyu’ndan sonra diğer gruplara göre Reçineli Su en fazla içildi (P<0,001). En düşük serum MDA düzeyi Doğal Kaynak Suyu içenlerde 1,54 μM/l ve en yüksek MDA düzeyi Reçineli suyu içen grupta 4,27 μM/l olarak saptanmıştır (P<0,001). Serum SOD ve CAT değerleri en yüksek Ozonlu Suyu içenlerde gözlenmiş ve sırasıyla 45,15 U/l ve 60,40 kU/l olarak kaydedilmiştir. Denemede su çeşitlerinin kesim ağırlığı, karkas ağırlık ve karkas randımanına bir etkisinin olmadığı belirlenmiştir (P>0,05). Sonuç olarak su çeşitlerinin önemli etkilerinin olduğu, şebeke sularına reçine katmanın suyun dezenfeksiyonu ve yumuşatılmasında önemli bir katkı yapmadığı, sudaki çözünmüş madde miktarının (TDS) canlı ağırlık, GCAA, yem tüketimi, su içimini, YYO ve oksidatif stres biyomarkerlerini olumlu yönde etkilediği, Reçineli Su hariç 4 su tipi için sıralamanın; 1-Doğal Kaynak Suyu, 2-Ozonlu Su, 3-Selestit Taşlı Su ve 4-Şebeke Suyu olduğu belirlenmiştir.; ABSTRACT This study was conducted to aim the effects of 5 types waters with Ozonated (available commercial pet water), Resinous (100 g pine kindling/4.5 l city water), Chlorotic (city water), Celestite Stone (200 g/4.5 l city water) and Natural Spring (Karliova Fountain, Around of The Hospital of Women-Children Bingol, Turkey) on performance, oxidative stress and carcass parameters in Japanese quails. A total of 150 three days old mixed female-male quails were divided into 3 subgroups of 10 birds, including 30 birds in each water group. The experiment was continued for 7 weeks. The experimental diet of one type (CP 26.14% and ME 3069 kcal/kg) and five different water types were given ad libitum for animals during in the trial. The analysis of water types used in the experiment were observed statistical differences on pH, Ca, Mg, Cl, Electrical Conductivity and Total Bacteria. Live weight, daily live weight gain and feed intake were the highest in the drinking group of Natural Spring Water, while the lowest was found at Resinous Water group (P<0.001). More less drinking group of Resinous Water than Natural Spring Water were drank maximum compared to other groups (P<0.001). The lowest level of serum MDA of drinkers Natural Spring Water was determined 1.54 μM/l, and the highest MDA levels drinkers of Resinous Water was 4.27 μM/l (P<0.001). Serum SOD and CAT highest values were recorded in drinkers of Ozonated Water as 45.15 U/l and 60.40 kU/l respectively. Types of water varieties of trial were determined no effects on slaughter weight, carcass weight and carcass yield (P>0.05). As a result, the effects of types of water was important, and the resin into water was no profitable for disinfection and softness of city water, and the amount of total dissolved solids (TDS) of water were the positive effect on live weight, ADG, feed consumption, water intake, FCR and oxidative stress biomarkers, and except Resinous Water, the ranking were determined for four water types; 1-Natural Spring Water, 2-Ozonated Water, 3-Celestite Stone Water and 4- Chlorotic Water.

Comparison of fattening performance, carcass characteristics, and egg quality characteristics of Japanese quails with different feather colors Söğüt, Bünyamin; Şengül, Turgay; Şengül, Ahmet Yusuf; Taysı, Mehmet Reşit; İnci, Hakan The objective of this study was to compare fattening performance, carcass traits, and egg quality of Japanese quails with different feather colors (white, dark brown, golden, and wild-type). In the study, 360 one-day-old quail chicks with 4 different feather colors were used as animal material. Quails were fed ad libitum for 42 days to determine fattening performance and carcass traits. To determine egg traits, 48 hens from each group, in a total of 192, were selected and caged according to feather color. Eggs were collected for four consecutive weeks and egg quality characteristics were measured. Different feather colors had a significant effect on live weight, feed intake, feed conversion ratio, and carcass characteristics. Significant differences between the groups were detected for egg weight, specific gravity, shape index, shell weight, albumen weight, yolk weight, albumen index, and yolk index. Japanese quails with all four feather colors can be reared depending on the choice. However, due to lower feed conversion ratio, white-feathered quails may be preferred for meat production purposes. Color variations should be considered when selecting quails.

Effects of beak trimming, stocking density and sex on carcass yield, carcass components, plasma glucose and triglyceride levels in large white Turkeys Şengül, Turgay; İnci, Hakan; Şengül, Ahmet Yusuf; Söğüt, Bünyamin; Kiraz, Selahattin This study was conducted to determine the effects of beak trimming, stocking density (D) and sex (S) on live weight (LW), carcass yield and its component, and plasma glucose (PG) and triglyceride levels in Large White 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 m2/bird. (D) × sex (S) interaction had an effect on both CP and thigh weights (p< 0.05). Significantly D×S was observed in LW, CP and PG. The weight of carcass and its some components were higher in male. S×D interaction had an effect on plasma glucose level (p<0.05). Triglyceride level was affected (p<0.05) by sex. Significant relationships were found between percentage of thighs (r=0.447, p<0.01) and percentage of breast (r=0.400, p< 0.01). According to this study, it can be said that trimming is useful with density of 0.25 m2/bird in turkey fattening.

Tavuklarda yaşa göre canlı ağırlığın interpolasyon yöntemiyle tahmini Şengül, Turgay; İnci, Hakan; Çelik, Şenol; Söğüt, Bünyamin; Şengül, Ahmet Yusuf Bu çalışmada 10 haftalık yaştaki tavukların yaşlara göre canlı ağırlık tahmini Newton interpolasyonu ile belirlenmiştir. Araştırmada, günlük yaşta 99 tavuk civcivi kullanılmıştır. Hayvanlar 10 hafta boyunca beslenmiş ve 7. günden 70. güne kadar olmak üzere 10 adet eşit aralıklı noktada fonksiyon değerleri için 9. dereceden bir interpolasyon polinomu elde edilmiştir. Elde edilen interpolasyon polinomu ile 7-70 gün arası tavuklarda canlı ağırlık tahmini yapılmıştır. Belirlenen canlı ağırlıklara göre tavuklarda günlük canlı ağırlık artışı saptanmıştır. Tavuklarda 70 güne kadar ortalama canlı ağırlık artışı 46.13 gram bulunmuştur. Tavuklarda canlı ağırlığın 31 günde 1 kg?ın üzerinde, 48 günde 2 kg?ın üzerinde ve 67 günde 3 kg?ın üzerinde olacağı tahmin edilmiştir. İnterpolasyon sonuçlarına göre, günlük canlı ağırlık artışı en yüksek yaklaşık 99 gram ile yedinci haftada, en düşük ise yaklaşık 12 gram ile onuncu haftada tespit edilmiştir.
