Abstract

Genetic, environmental and phenotypic correlations between different periods of live weights in Rabbits were estimated. Number of sires and dams which were not relationship each other 21 and 42, respectively for each set groubs in this study. Number of first set groub were 271, 278, 278 and 285, number of second set groubs were 284, 293, 289 and 298 respectively half-sibs live weights were analyzed for 0, 7, 15, 30, 45, 60 and 90th. days. Genetic correlations of each set groubs were estimated as positive highly. The correlations between birth and seventh day was estimated as the highest but other correlations were decreased gradualy. Phenotypic correlations, between all of periods were positive and exception of weaning weight, other correlations were from 0.8 to 0.9. The environmental correlations of all of periods were negative generally. Because of phenotypic correlations degree were positivs and high. It was satisfied to be not necessary to get criter of consequent periods.

Özet

Beyaz Yeni Zelanda Tavşanlarında çeşitli çağlarındaki ağırlıklarına ait genetik, çevresel ve fenotipik korrelasyonlar tahmin edilmeye çalışılmıştır. Araştırmada kullanılan baba sayısı her set grubu için 21 ve ana sayısı da 42'dir. Gerek analar gerekse babalar birbirlerine akraba değildir. Birinci set grubunda 271, 278, 278, 285 ikinci set grubunda 284, 293, 289 ve 298 baba-bir üvey kardeşin 0., 7., 15., 30., 45., 60., 75 ve 90'ıncı gün kayıtları analize tabi tutulmuştur. Elde edilen tahminler cetveller halinde verilmiştir. Her set grubundaki genetik korrelasyonlar pozitif ve yüksek değerde tahmin edilmiş olup doğumla 7. gün arasında en yüksek, daha sonraları giderek azalmaktadır. Fenotipik karrelasyonlar tüm dönemler arasında pozitif ve yüksek olmakla birlikte sütten kesim sonrası çağlar arasındaki korrelasyonlar (0.8-0.9) arasındadır. Çağlar arasındaki çevresel korrelasyonlar ise genellikle negatif olarak tahmin edilmiştir. Fenotipik korrelasyonların yüksek seviyelerde pozitif olması nedeniyle birbirine yakın çağlardaki iki ayrı ölçüyü almanın gereksiz olduğu kanısına varılmıştır.
