REPRODUCTIVE EFFICIENCY OF CAPTIVE CHINESE- AND INDIAN-DERIVED RHESUS FEMALES

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心赠款提供。次级项目的主要支助 子项目的主要研究者可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 表示子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 介绍：研究了303名中国血统和360名印度血统女性跨越3代的生殖记录（n = 2，913）。 第1、2和3代分别包括339、251和73只雌性。方法：采用最小二乘统计分析比较中国和印度女性的生殖性状。所有模型包括起源、代、起源×代和代内母兽出生年份。婴儿性别，出生顺序和婴儿存活状况被纳入特定性状的模型中。结果/讨论：中国女性首次生育年龄大于印度女性（5.0 <$0.06 vs 4.3 <$0.08岁; P 0.05）。 这些结果表明，母系起源在恒河猴雌性的一些生殖性状中起作用。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Introduction: Reproductive records (n = 2,913) from 303 Chinese-origin and 360 Indian-derived females spanning 3 generations were studied. Generations 1, 2, and 3 included 339, 251, and 73 females, respectively. Methods: Least-squares statistical analyses were used to compare Chinese and Indian females for reproductive traits. All models included origin, generation, origin x generation and dam birth year within generation. Infant gender, birth order, and infant survival status were included in models for particular traits. Results/Discussion: Chinese females were older at first reproduction than Indian females (5.0 ¿ 0.06 vs 4.3 ¿ 0.08 years; P0.05). These results demonstrate that maternal origin plays a role in some reproductive traits of rhesus macaque females.
