The aim of this research was to determine some non‐infectious factors (sex of calf, calf birth weight, calving season and dam parity and dam body condition score at dry and calving) that can under control by breeders affecting calf health status (CHS) in neonatal period. A total of 517 calves (from delivery of calf until 28 days) and their dams (at dry and calving) were assessed according to study criteria. Relationship between CHS and dam parity (DP), body condition score at calving (BCS_C), body condition score at dry (BCS_D), sex of calf (SC), calf birth weight (CBW), and calving season (CS) was examined and connection between CHS and BCS_D, CS, and CBW was found important. Also, influences of DP, SC BCS_C, and BCS_D on CBW were examined and while effects of DP and SC on CBW were found important, effects of others were not. These results show that relation between CHS and CBW, CS, and BCS_D is important and CHS is higher in female calves or calves born to multiparous dams. As a conclusion, it can be said that planning the herd management practices according to these results will be beneficial for the healthier completion of the neonatal period.

奶牛群非感染因素与新生犊牛健康状况的关系

本研究的目的是确定一些非感染性因素（小牛性别、小牛出生体重、产犊季节和母胎胎次以及干产和产犊时的母体状况评分），这些因素可以由饲养员控制，影响小牛健康状况 (CHS)在新生儿期。根据研究标准评估了总共 517 头小牛（从小牛分娩到 28 天）和它们的母牛（在干燥和产犊时）。CHS 与母胎胎次 (DP)、产犊体况评分 (BCS _C )、干胎体况评分 (BCS _D )、犊牛性别 (SC)、犊牛出生体重 (CBW) 和产犊季节 (CS) 之间的关系检查并发现 CHS 和 BCS _D、CS 和 CBW 之间的联系很重要。此外，DP、SC BCS _C和 BCS _D的影响对 CBW 的影响进行了检查，虽然发现 DP 和 SC 对 CBW 的影响很重要，但其他因素的影响并不重要。这些结果表明，CHS 与 CBW、CS 和 BCS _D之间的关系很重要，并且 CHS 在雌性小牛或多胎母牛所生的小牛中较高。总之，可以说根据这些结果规划畜群管理实践将有利于新生儿期更健康地结束。
