The number of records used for milk yield in the statistical analysis is 1457. Therepeatability related to the milk yield characteristics was estimated to be between 0,005 and 0,244. Because of thefact that the repeatability was estimated to be low; it is believed that it might be useful to make the selection basedon the mean of two or more records. Estimating the repeatability; the Minimum Quadratic Unbiased Estimationmethod is most likely to give reliable results for the calving period, dry period and lactation period that meets ther>2Sr condition while REML and ML methods are most likely to give the most reliable results for lactation milkyield and MQUE, VA, REML and ML methods are most likely to give the best results for the adjusted milk yield(2x350 Max.).eninfo:eu-repo/semantics/openAccessZiraat MühendisliğiArticle10.13002/jafag44528417532760935
