The aim of this study was to determine several obstetric and neonatal parameters in the Maine Coon breed. The birth data of Maine Coon breeding population were collected of 52 litters from different households using a questionnaire. Significant relationships between various outcomes and the relevant predictors were assessed by multiple linear regression or logistic regression, as appropriate. The overall mean gestation length was 65.5±1.32 days. Larger litter size was associated with shorter gestation lengths (p⟨0.01). Mean litter size was 5.3±2.3 kittens. The weight of kittens born alive (overall mean 119.6±18.4 g) increased with prolonged gestation lengths (p⟨0.01) and decreased with larger litter sizes (p⟨0.01). In the analyzed group of kittens, 12.5% were stillborn. The expulsion intervals varied widely. The duration of the first stage of labour was less than 2h in 82.9% of the cats. The interval between the birth of the first and the last kitten was less than 6h in 99.3% of the cats, and it exceeded 6 h in only 2 cats. The present results can be used to develop references values and reliable assistance protocol for assessing the parturition in the Maine Coon to protect the queen and reduce perinatal losses.
本研究的目的是确定缅因猫品种的几个产科和新生儿参数。通过问卷调查收集了来自不同家庭的52窝缅因猫繁殖群体的出生数据。根据情况，通过多元线性回归或逻辑回归评估各种结果与相关预测因素之间的显著关系。总体平均妊娠期为65.5±1.32天。窝仔数较多与妊娠期较短相关（p＜0.01）。平均窝仔数为5.3±2.3只小猫。存活出生小猫的体重（总体平均119.6±18.4克）随着妊娠期延长而增加（p＜0.01），并随着窝仔数增加而减少（p＜0.01）。在分析的小猫组中，12.5%为死产。排出间隔差异很大。82.9%的猫第一产程持续时间少于2小时。99.3%的猫第一只和最后一只小猫出生之间的间隔少于6小时，只有2只猫超过6小时。目前的结果可用于制定参考值和可靠的辅助方案，以评估缅因猫的分娩情况，保护母猫并减少围产期损失。
