KONYA MERİNOSLARINDA ÖNEMLİ BAZI DÖLVERİMİ ÖZELLİKLERİNİN FENOTİPİK VE GENETİK PARAMETRELERİ VE BU ÖZELLİKLERİN SELEKSİYONLA ISLAHI ÜZERİNDE ARAŞTIRMALAR
Öz
Summary: Fertility records, obtained over 6 years (1965-1971), from a Konya Merino floek of about 500 breeding cwes, have been analized to study the possibilities of improvement through selection in thenumber of lambs bom per ewe mated (TKDK) number
oflamos weaned per ewe mated (TKSK), number oflambs bom per ewe lambed (DKDK)
and number of lambs weaned per per ewe lambed (DKSK). For this purpose, repeatabilities have been cstimated with intra-class correlation method, and heritabilities with
paternal half-si b correlation method. The effects of year and ewe's age on the above traits
were also examined by estimating their magnitudes with the leastsquares procedure. All
available rocords wcre used for studying the environmental effects, while repeatability analyses were performed considering only the records of ewes which had records in two or more
years. For the heritability analyscs, records obtained in the first two performance years
(at 2 and 3 years of age) were empIoyed
