Özet

This study was undertaken to investigate the effects of certain factors on birth weight and survival rate, utilizing the records of 8399 Holstein calves maintained at the Ceylanpinar State Farm in southeastern Anatolia. The data were collected from the calf barn sheets, including birth weight, pedigree details, and calf fate. The survival rate was scored as 1 (alive) or 0 (died) in accordance with the records.
