The aim of the study was to identify quails which have different body weight for some production traits such as egg production, egg characteristics, daily feed consumption and feed conversion ratio (FCR). The selection was based on body weight in Japanese quail over two generations using 150 quails (120 female and 30 male). These groups consisted of Low Body Weight (LBW), High Body Weight (HBW) and control. Average body weights for females at the end of five weeks were 182.3±0.5, 159.5±0.34, and 141.7±0.55 for LBW, HBW and control groups respectively. There were significant differences between females and males in body weight across the generations. Significant differences were observed for total egg production and egg width for Group X Generation's interactions. Also, statistically significant differences were found for egg quality parameters such as yolk index, yolk height, yolk diameter, albumin length, and albumin width among generations. As a result, body weight is a very important factor in selection studies and it also increases the efficiency of the selection program with other selection features.

This study aims to examine the effects of environmental enrichment (EE) practices on some physiological and behavioral parameters of broiler chicks. A total of 280 one-day old Ross 308 mixed-sex broiler chicks with an average initial body weight of 44.5±0.37 g were used in a 42-d trial. Broiler chicks were randomly allocated to 20 pens composed of 14 birds in 1x1.4m sized floor area. Each of the EE treatment consisted of 5 replicate pens (70 chickens per treatment). The treatments were 1) control; 2) perch for EE; 3) ball for EE; 4) mirror for EE; and 5) dust for EE. Final body weights, tonic immobility test results, and rectal temperatures were recorded. Spleen, liver, and bursa fabricius weights were measured. The blood biochemistry of birds was analyzed at the end of the experiment. Besides, gait score test was applied on the 42 nd day of experiment. Body weight gain, lymphoid organ weights and rectal temperature values of broilers were not affected by EE treatments on the 21 st and 42 nd days of the study. At the end of the study, WBC values, tonic immobility values and gait scores of the control groups were found higher than those of the EE groups. HCT and PLT values of the ball groups were found lower than the other groups, concluding that EE improved the welfare of birds.

This study was conducted to develop long-term storage methods for turkey semen using different extenders. During the study, the massage method was used twice a week to collect the semen from five turkeys, a total of 44 times. The collected fresh semen's average ejaculate quantity, sperm concentration, motility and vitality values were determined as 0.22±0.01 ml, 3.5±0.17 x10 9 sp/ml, 77.0±1.44% and 86.2±0.95 % respectively. In this study, glucose (G) including 5% Dimethyl sulphoxide (DMSO) cryoprotective, tris-glucose (TG), lactated Ringer's (LR), and lactated Ringer's glucose (LRG) extenders were used. The Turkey semen was combined and divided into four equal parts, and subsequently diluted at a ratio of 1:3 and equilibrated at +4°C for 90 minutes. Following equilibration, the samples were frozen in liquid nitrogen vapor to -80°C for five minutes, and stored at -196°C in liquid nitrogen. After freezing and thawing, the highest motility value was obtained from the G extender (43.3% ±1.62%) followed by LRG (24.6±1.53%), LR (12.6±0.92%) and TG (12.2±0.66%).The vitality values were recorded as 55.8±1.89%, 23.8±1.58%, 21.5±1.10% and 36.5±1.59% respectively. The motility and vitality values were significantly (p<0.01) more for the glucose extender than those for other extenders. Therefore, it was concluded that glucose extender is better option for the long-term storage of Turkey semen.

-This study compared the growth curve models for the live weight and body length of Japanese quail raised under lights of various colors. The Brody, Gompertz, and von Bertalanffy growth models were used to investigate the effect of different colored lights on Japanese quail growth over a period of six weeks (1-42 days). Four lights of different colors, comprising yellow, red, blue, and white, were used in the study. According to the different light colors, the mean and standard error for the live weight and body length on day 42 were calculated as 196.09 and 3.87 g and 29.48 and 0.192 cm, respectively. Furthermore, while the differences in live weight according to the color of the light being used were statistically significant on days 14, 21, and 28, there were significant differences in body length on days 7, 28, 35, and 42, depending on the color of the light used. The highest values of R 2 for body length and live weight were 0.9935 and 0.9988; the lowest sum of square error values for body length and live weight were 9.6588 and 10.6623 according to the Gompertz model. Test results did not reveal autocorrelation among serial data except for those grown under red colored lights.

The aim of this study is to investigate the behaviors of and monitor the changes on behaviors of Japanese quails reared in different stocking density, through using different objects, (small red balls, bunch of rope, mirrors and beads) providing environmental enrichment (EE) in the cages of quails. Six hundred of 1 day old Japanese quail chicks (mixed sex) were used in this study. Birds were reared in battery cages with four floors, each of which has two separations. The quails were placed in cage dimension in the quantities of 10 quails (lower density: LD) and of 20 quails (higher density: HD) per separation. Our hypothesis was that EE would improve the welfare of quails. The birds were observed in their cages naturally in accordance with one-zero sampling, and home cage avoidance test was performed for these birds. While the applications have significant effect on feeding and relaxation behaviors (P<0.05 levels) in LD environment, the effect of comfort, social and other behaviors was realized at P<0.01 levels in the same environment. However in HD environment, only rest behavior was affected significantly in P<0.05 level, the other properties were affected in P<0.01 levels. The live weights weren't affected from EE (for LD, P=0.134 and for HD P=0.216). It was determined in the result of this study that the objects hung in the quail cages had potential effect to improve the welfare of quails.

This study was carried out to investigate the behavioural responses of white and bronze turkeys to tonic immobility (TI), gait score (GS) and open field (OF) tests in a free-range system. 144 female turkeys (72 white and 72 bronze) were studied for 23 weeks. They were 32 weeks old. The stocking density was 2 birds/m 2 indoors and 0.66 birds/m 2 outdoors. Both bird genotypes were fed on a diet containing 16% crude protein and 11.7 ME MJ/kg. The birds were weighed in the 32nd, 35th, 48th and 55th week. The turkeys' behaviour was determined by TI, GS and OF tests. Behavioural parameters were established for each applied test. Although the mortality rates of white and bronze turkeys during the study were 6% and 3%, respectively, the white turkeys showed better results in the TI and OF tests suggesting that are more native breed than bronze ones. The results indicate that bronze turkeys are more suited for use in free-range systems than white turkeys with respect to GS and the consequent mortality rates in latter ones.

Bu çalışmanın amacı, Türkiye genelinde bazı illerde, bal başta olmak ve arı ürünleri tüketimini etkileyen faktörler ile arı ürünlerinin tüketim alışkanlık ve farkındalık düzeylerini değerlendirmektir. Çalışmanın ana materyalini, 2014 yılı içerisinde Batman, Bursa, Diyarbakır, Erzincan, Kayseri, Kırşehir, Mersin, Muğla, Muş, Ordu ve Samsun illerinden tesadüfî olarak seçilen 1112 kişiye yapılmış olan anket çalışmasından elde edilen orijinal veriler oluşturmuştur. Çalışmadaki veriler iki kısımda incelenmeye alınmıştır. İlk kısım ankete katılanların bal tüketim alışkanlık ve farkındalıklarını içerirken, ikinci kısımda bireylerin polen, propolis, arı sütü ve arı zehiri gibi arı ürünlerinin kullanım tercihleri incelenmiştir. Her bir kısım için arı ürünleri üzerinde çalışılan değişkenlere ait verilere çok değişkenli lojistik regresyon modeli uygulanmıştır. Araştırma sonuçlarına göre, tüketicilerin %39,6'sı aylık olarak 0-500 gram arasında bal tükettiği tespit edilmiştir. Tüketicilerin %51,2' si balı genel olarak tanıdığı arıcılardan, %41'i ise market ve pazardan aldıklarını belirtmişlerdir. Televizyonda yapılan reklamları inandırıcı bulanların oranı %5,9 olarak belirlenmiştir. Bal kullananların %45,8' i balın kalitesini anlayabildiğini ifade etmişlerdir. Marka olmasına dikkat edenlerin oranı %52,7 olarak belirlenmiştir. Tüketicilerin yaşı, balı nereden aldığı, balda marka tercihi ve bal reklamlarını inandırıcı bulma durumları 0,05'e göre, eğitim seviyesi, aylık gelir, bal tipi tercihi ve bal reklamından etkilenme durumları ise 0,01'e göre önemli bulunmuştur. Tüketicilerin propolis, polen, arı zehri ve arı sütü hakkında bilgi düzeyleri oranları sırasıyla %28,2; %22,9; %56,8 ve %23,3 olarak belirlenmiştir. Sonuç olarak çalışma, tüketicilerin arı ürünlerinin faydaları konusunda nispeten bilgili olmalarına rağmen, bu ürünlere karşı ciddi anlamda güven sorunlarının olduğunu da göstermektedir.
