Forty-four (44) birds (about 50 weeks old) male and female inbred naked necked and frizzle feathered chickens were crossed to generate F1 crossbred chicken that were used to evaluate the performance and heterosis effects. Data taken on 180 chicks (97 NN and 83 FF) day-old chick weight (BWT0), body weight (BWT), daily average feed intake (AFI), feed conversion ratio (FCR), brooding and rearing mortalities, linear body measurements (LBM): body length, wing length, keel length, shank length and breast width were used to estimate heterosis and performance of F1 progenies. Results of the experiment showed positive heterosis with significant differences among the F1 progenies over their parents in body weight, average feed intake and feed conversion ratio. The reciprocal cross (i.e. frizzle feather rooster x naked neck hen) showed a significant improvement in their performances genetically, explaining that better results are achieved through crossbreeding of these indigenous breeds. With reference to their body linear parameters, the reciprocal cross of naked neck and frizzle feathered chickens developed higher body length, whereas the main crosses performed better in their wing length, keel length, shank length and body width respectively, mainly after 8 weeks suggesting that earlier performance was attributable to maternal influences.

Yaklaşık 50 haftalık yaşta, 44 adet erkek ve dişi kan yakınlığı olan çıplak boyun ve kıvrık tüylü (frezzled feathered) tavukların F1 melezlemesi yapılarak performans ve heterozis etkileri incelenmiştir. F1 döllerinin performans ve heterozis özelliklerini saptamak için 1 günlük yaştaki 180 adet (97 çıplak boyun ve 83 kıvrık tüylü) civcive ait başlangıç canlı ağırlığı (BW0), canlı ağırlık (BW) ortalama günlük yem tüketimi (AFI), yem dönüşüm oranı (FCR), kuluçka ve yetiştirme döneminde ölüm oranları, linear vücut ölçüleri (LBM): vücut uzunluğu, kanat uzunluğu, göğüs kemiği uzunluğu, bacak uzunluğu ve göğüs genişliği ölçümleri değerlendirildi. Deneme sonuçları F1 melezleri arasında vücut ağırlığı, ortalama yem tüketimi ve yem dönüşüm oranı bakımından önemli derecede pozitif heterozis olduğunu göstermiştir. Karşılıklı çaprazlama (kıvrık tüylü horoz x çıplak boyun tavuk) ile genetik performansta önemli iyileşmenin görülmesi, bu yerli ırkların melezlemesiyle daha iyi sonuçların elde edileceğini açıklamaktadır. Vücut linear parametreleri referans alınarak çıplak boyun ve kıvrık tüylü tavukların karşılıklı çaprazlamaları ile, daha önceki haftalardaki performans anasal etkilere atfedilerek, özellikle 8 haftadan sonra daha yüksek vücut uzunluğu, bacak uzunluğu ve vücut genişliğine sahip piliçler geliştirildi
