The impacts of breeder age (32 and 55 weeks), egg storage time (2-12 days), setter ventilation program (control-test) on incubation and post-hatch performance of broilers were investigated in this study. Young (Y) and old (O) breeders' hatching eggs were incubated in two different setters operated by two different ventilation programs as control (C) and test (T). Incubation took place after a short (S) and long (L) time of storage in this study. According to the trial design, eight treatment groups were as YSC, YST, YLC, YLT, OSC, OST, OLC and OLT. In total 9600 eggs and 6400 chicks were used. Early stage embryonic mortality (ED) rates were lower and accordingly hatchability of fertile eggs (HF) were higher (p<0.05) in YS than the other treatment groups. In contrast, incubation performance in eggs hatched in C and T programs were found to be similar. However, interaction between treatments were significant (p<0.05) and ED and HF were significantly (p<0.05) improved at OC. Liveability in growing period was affected (p<0.05) by breeder age but it wasn't affected by storage time and incubation program. Higher post-hatch performance was achieved in chicks of OST but differences between groups weren't significant except for chick weights in comparison by breeder age. However, interactions between treatments were significant (p<0.05) and reached the highest post-hatch performance in YST (p<0.05). In conclusion, the long time storage of old breeders' eggs improved incubation and posthatch performance when they were incubated at test program.

The study was carried out to evaluate the effects of early feeding on development of turkey poults. A total of 414 day-old Nicholas turkey pouts were obtained from a hatchery of an integration in Bolu province for the two experiments. The poults are divided into two groups, which are the poults fed with starter diet and the fasted (control) group of birds in each experiment. Experiments were held in summer and in winter periods respectively. The effects of early feeding on the transportation boxes to the live weight is observed at 1, 2, 4, 6. weeks of life and liveability of the poults are controlled daily. Corresponding to the data obtained in this research, we concluded that poults allowed to access early feeding had better (P˂0.05) live weights during the first week of their lives. But this advantage ended in the second week and didn't show up again during the 6 weeks' time (P˃0.05). The mortality was observed to be higher in fasted groups. Feed consumption of the groups also seemed not to be affected by the application.

Abstract:In this review, features and new trends on Turkish poultry industry are evaluated. Turkish poultry industry has rapidly developed in last years in especially broiler meat and egg production. As a result of these developments, The Turkish poultry sector is recognized as an industry. The industry has advantages such as modern facilities and production methods, thanks to international standards and international markets in close proximity, making it able to compete with the whole world. However, industry has some problems such as the high costs of the production and dependence on external inputs for raw materials in feed and breeders. Fortunately, Turkey is an interesting country that can adapt very quickly to emergencies. Turkish poultry industry is trying to adapt to new and difficult conditions and often succeeded. The policies being followed by the elimination of dependence in foreign, measures taken to reduce costs and the growth of the industry are supported in an increasingly manner to increase production and consumption. Thus, it is aimed that the Turkish poultry industry became much more useful industry on reduction in unemployment and finding a solution to the immigration problem by healthier, faster and planned development.

Et tipi tavukların seleksiyonu öncelikle büyüme hızına ve vücut kompozisyonunun geliştirilmesine odaklanmıştır. Büyüme ve üreme ile ilgili özellikler arasındaki negatif ilişki ıslah ve yetiştiricilik uygulamalarını zorlaştırmaktadır. Tavuk ıslahıyla ilgili çalışmalar yaklaşık 150 yıllık bir geçmişe dayanıyor olmasına karşın üretimdeki verim artışları son 75 yıllık dönemde sağlanabilmiştir. Damızlık hayvanlar seçilirken; iskelet yapısı, vücut konformasyonu ve kondisyonu, morbidite vb. fenotipik özellikler dikkate alınmaktadır. Yıllar içinde etlik ebeveyn düzeyinde kuluçkalık yumurta sayısı, yumurta ağırlığı ve kuluçka randımanı açısından ilerleme kaydedilmiştir. Et tipi tavuklar için, 20. yüzyılın ilk çeyreğinde kesim yaşına kadar günlük canlı ağırlık artışı ortalama 8 g ve yemden yararlanma oranı 5,0 iken 21. yüzyılın başında bu özellikler için sırasıyla 66 g ve 1,7 değerlerine ulaşmıştır. Etlik piliç üretiminde kullanılan genotiplerin canlı ağırlığındaki ve yemden yararlanma oranındaki iyileşmede etkili asıl faktör genetik çalışmalardır. Bu gelişmelerin yanında, etlik piliçlerin bağışıklık sistemi, iskelet sistemi bozuklukları, yaşama gücü ve damızlıklardaki üreme ile ilgili bazı olumsuzluklar ortaya çıkan sorunlardır. Evolution of Broilers and Broiler Breeders A R T I C L E I N F O A B S T R A C T Review ArticleReceived 11 December 2017 Accepted 27 December 2017Selection of meat-type chickens is primarily focused on growth rate and body composition improvement. The negative relationship between growth and reproduction related characteristics makes rearing and breeding applications difficult. Although the studies on chicken breeding have more than 150 years of history, the speed-up have been derived only in last 75 years. While selection breeding birds based on their phenotype for such traits as skeletal integrity, body conformation, condition, morbidity etc. Over the years, progress has been made in terms of number of hatching eggs, egg weight and hatchability at the parent stocks. For the meat-type chickens, the average body weight gain was 8 g per day and feed conversion rate was 5.0 until the age of slaughter in the first quarter of the 20th century, whereas at the beginning of the 21th century, these characteristics reached 66 g and 1.7, respectively. Improvement in body weight and the feed conversion ratio of the genotypes which have been used for broiler production is because of the development in genetics. Besides these developments, some problems have surfaced regarding immune function, skeletal disorders, liability, and in the breeder level reproductive troubles.

Dünya'da gıda eşit dağılmamaktadır. Gelişmiş ülkelerin sağlıkla ilgili sorunu obezite iken, diğer ülkeler açlık ve buna bağlı hastalıklarla karşı karşıyadır. Dünya nüfusunun 2050 yılına kadar 1/3 oranında artacağının bekleniyor olması hayvansal protein üretiminin de artırılmasını zorunlu kılıyor olacaktır. Türkiye'de kişi başına toplam et tüketimi 35 kg, kanatlı eti ise 22 kg'ı aşmıştır ve yumurta tüketimi 200 adet iken yaklaşık 230 lt süt tüketimi bildirilmektedir. Günlük hayvansal protein tüketimimiz 35 g civarındadır ve iletişim çağına ayak uydurabilmek bakımından 45-50 g seviyesine çıkarılması önerilmektedir. Dünyada en yüksek artış kanatlı et sektöründe ve bunu takiben yumurta tavukçuluğu sektöründe görülmektedir, bu artış ülkemiz için dünya ortalaması üzerinde iken kırmızı et üretiminde dünya ortalamasının gerisinde kalınmıştır. Görsel, yazılı ve sosyal medyada bilimsel dayanağı olmayan haberlerin oluşturduğu bilgi kirliliği tüketicilerin olumsuz yönde etkilenmesine sebep olmaktadır. Özellikle gençler başta olmak üzere tüm bireyler, biyolojik değeri yüksek olan yumurta, süt ve et ürünlerini doğal ihtiyaçları düzeyinde tüketebilmelidir. Organik ve free-range sistemlerden elde edilen ürünlere talep eden tüketiciler rahatlıkla ulaşabilmelidir. Ancak hangi sistemde üretilmiş olursa olsun, ürünlerin güvenilir kaynaklardan geldiğinden, üretim tarihi ve sağlıklı bir şekilde elde edildiğinden emin olunmalıdır. Bu derlemede, zihin ve beden gücü yüksek nesiller yetiştirilmesi bakımından son derece önemli olan hayvansal protein kaynaklarından yeterince faydalanılması için artan insan nüfusunu beslemede kanatlı üretiminin etkinliğinden bahsedilmektedir. Efficiency of Poultry Production in terms of Quality and Balanced Nutrition A R T I C L E I N F O A B S T R A C T Review ArticleReceived 04 December 2017 Accepted 27 December 2017In the World, food isn't equally distributed. While the health problems of developed countries are obesity, other counties are facing hunger and related diseases. The expectation that the wold population will increase by 1/3 until 2050 will make it necessary to increase animal protein production. It was noted that, in Turkey, per person, red meat consumption is 35 kg, poultry meat is more than 22 kg, while egg consumption number is 200, milk is 230 litres. Our daily protein expenditure is about 35 kg and it is recommended that it should be between 45-50 kgs to suit up the communication age. The highest development rate belongs to white meat industry and breeding chicken industry follows. While this development rate is over the World average in our country, the rate of red meat is lower than the World average. The Information pollution, which is produced by social media and media, is causing consumers to be affected negatively. All population especially the young population should consumption egg, milk, meat and their productions which are very rich for their biological values as their natural need levels. Consumers demanding products obtained from organic and free-range systems should be able...
