Abstract

Ozet Bu arastirma farkli yerlesim sikliginda yetistirilen BUT Big 6 genotipindeki erkek hindi hibritlerinin besi performansi, yasama gucu ve karkas kalitesi Ozelliklerinin arastirilmasi amaciyla yurutulmustur. Yerlesim sikliginin performans uzerine etkilerini incelemek amaciyla iki deneme grubu olusturulmustur. Grup 1 ve IT ye m 2 taban alani icin sirasiyla 3 ve 4 erkek hindi yerlestirilmistir. Toplam olarak Grup I'de 3900. Grup H'de 3000 erkek hindi civcivi kullanilmistir. 124 gun suren besi sonundaki canli agirlik Grup 1 icin 15.34 kg. Grup II icin 14.41 kg olarak saptanmistir. Yerlesim sikliginin canli agirlik uzerine etkisi 8 haftalik yasa kadar onemsiz, besinin 9-18. haftalari arasinda ise Grup I'deki hindilerin lehine onemli bulunmustur (P<0.05). Toplam yem tuketimi ve yemden yararlanma orani sirasiyla Grup I icin 40-45 kg ve 2.64; Grup II icin 37.22 kg ve 2.58 olarak elde edilmistir. Grup 1 ve II icin yasama gucu sirasiyla %94.3 ve %86.3 olarak belirlenmistir. Yerlesim sikliginin yasama gucu uzerine etkisi besinin ilk 96 gununde onemsiz. 105. gunden sonra ise onemli bulunmustur. Grup I ve Grup II icin sicak karkas agirligi sirasiyla 11958.3 g ve 11154.7 g. sicak karkas randimani ise %77.55 ve %77.10 olarak saplanmistir.

In order to determine the effect of stocking density on performance, two experimental groups were designed. The floor space allowances were 3 toms/m 2 in Group 1 and 4 toms/nr in Group II. In total, 3900 toms in Group I and 3000 toms in Group II were used. Final weight at 124 days of age were 15.34 kg for Group I and 14.41 kg for Group II. The effect of stocking density on live weight was not significant for the first 8 weeks. However, it was significant between 9 and 18 weeks of age. and Group I had higher live weight than Group II (P<0.05). Total feed consumptions and conversion ratios were 40.45 kg and 2.64 for Group I and 37.22 kg and 2.58 for Group II. Survival rates of Group I and II were 94.3% and 86.3%, respectively. The effect of stocking density on survival rate was not significant from 0 to 96 days of growth, but it was significant after 105 days of age. The hot carcass weights were 11958.3 g and 11154.7 g. hot dressing percentages were 77.55 % and 77.10% for Group I and II, respectively. Key Words: Turkey, Stocking density, Growth, Survivability, Carcass quality
