The effects of naked neck (Na) gene and sex on the apparent ileal Nitrogen and amino acids digestibility in Growing Meat Type Chicken

Year 2015, Volume: 12 Issue: 2, 23 - 27, 01.10.2015

Abstract

This experiment was conducted to investigate the effects of naked neck gen (Na) and sex (male and female) on the ileal nitrogen and amino acids digestibilties. Chicks were assigned to 4 treatment pens, 2 gene types (homozygous NaNa and heterozygous Nana, naked neck) and 2 sexes, containing 18 chicks each. Chicks in all treatments were fed the same diet. Results showed significant effect of the sex on the final live weight. Therefore, the male birds were 11.6% more heavily than females. On the other hand, neither the sex nor the gene showed significant effect on the gut length and organ weights (gizzard and liver). In addition, there were no significant effects of gene or sex on the ileal nitrogen and amino acids digestibilities, but the male birds had a numerically higher nitrogen and amino acid ileal digestibility compared with female birds and There were negligible differences in amino acid digestibility for birds with Nana gene compare with NaNa gene. However, more researches are required to confirm these results.

Etlik piliçlerde çıplak boyun geni ve cinsiyetin ileal azot ve amino asit sindirilebilirliği üzerine etkileri

Year 2015, Volume: 12 Issue: 2, 23 - 27, 01.10.2015

Abstract

Bu çalışma çıplak boyun geni (Nacked Neck-Na) ve cinsiyetin (erkek ve dişi) ileal azot ve amino asit sindirilebilirliği üzerine etkilerini araştırmak üzere yürütülmüştür. Bu amaçla civcivler, her birinde 18 adet civciv bulunan, 2 gen (homozigot NaNa ve heterozigot Nana) ve iki cinsiyet grubu olmak üzere toplam 4 deneme grubuna ayrılmıştır. Bütün deneme gruplarında hayvanlar aynı rasyon ile beslenmişlerdir. Cinsiyetin, final canlı ağırlığı önemli derecede etkilediği görülmüştür. Bu bağlamda erkek piliçlerin canlı ağırlığı dişilerden % 11.6 daha yüksek bulunmuştur. Diğer taraftan ne cinsiyetin ve ne de genin bağırsak uzunluğu ve organ ağırlıkları (taşlık ve karaciğer) üzerinde herhangi bir etkisi görülmemiştir. İleal azot ve amino asit sindirilebilirliğinin erkeklerde dişilere göre yalnızca rakamsal olarak yüksek olması dışında, gen ve cinsiyetin azot ve amino asit sindirilebilirlikleri üzerinde önemli bir etkisi olmamıştır. Nana geni ile NaNa geni karşılaştırıldığında amino asit sindirilebilirliğindeki farklılık önemsiz bulunmuştur. Bununla birlikte, daha fazla araştırma yapılarak bu sonuçların desteklenmesi gerekmektedir
