Farklı genotipten yumurtacı tavukların eşdeğer çevre koşullarında karşılaştırmalı verim özellikleri

Bu çalışma; Brown Nick, Isa Brown ve Tetra-SL yumurtacı hibritlerin eşdeğer çevre koşullarında büyüme ve üretim dönemi verim performanslarını incelemek amacıyla yapılmıştır. Her bir genotipten 1600 adet günlük civciv altlıkh yer sisteminde büyütüldükten sonra 16. haftada tavuk başına 45 cm2 alan düşen apartman sistemi kafeslere nakledilmiş ve 72 haftalık yaşa kadar verimler incelenmiştir. Brown Nick, Isa Brown ve Tetra-SL hibritlerin 18. hafta ağırlıktan sırasıyla 1481, 1517 ve 1514 g; büyüme (0-18. hafta) dönemi ölüm oranları %2.81, 1.75 ve 1.50 (P

Comparative production prameters of different layer genotypes in the same rearing condition

This study was carried out to investigate the growing and production parameters of Brown Nick, Isa Brown and Tetra SL hybrids in the same rearing conditions. 1600 chicks from each genotype were used and they reared on litter system till 16th week. After 16 week age they are moved battery cages where for each pullet has 45 cm2 field, and their production were examined till 72 week. The weight of Brown Nick, Isa Brown and Tetra SL genotypes in 18 weeks of age were found 1481, 1517 and 1514 g, respectively. The mortality rate in growing period of above groups were found 2.81, 1.75 and 1.50% (P
