A 4% rise in the rate of first births to older teens, ages 15 to 19, is also playing a role. And the sheer size of the baby boomlet generation, now entering the child-bearing years, may be skewing new mothers' mean age lower.
年龄在15岁-19岁的年轻女性中初产率上升了4%，这也起到了一定的作用。80后和90后女性现在都进入了生育年龄，这可能将女性的平均初产年龄拉低。

Nine multiparous and 12 primiparous cows were fed diets containing an anionic salt supplement and moderate Ca (0.99%) or high Ca (1.50%) concentrations for 21 d prepartum to determine the effects of dietary Ca concentration on serum and urine electrolytes and on postpartum intake and milk yield.
通过产前21天连续给予9只经产和12只初产的奶牛喂食含有阴离子盐补充剂和中等浓度（0.99%）或高浓度（1.50%）钙的饲粮来检测饲粮中钙的浓度对血清中和尿中电解质的影响以及对产后采食量和牛奶产量的影响。

Results］ In the one-way analysis, the risk factors of breast cancer are history of benign breast diseases, high body mass index, early age at menarche, family history of carcinoma, late age at primiparity, high frequency of abortion, a large age at last parturition, and swell or pain in breast during menstruating.
结果］ 单因素分析，达到统计学显著性水平的危险因素有乳腺良性疾病史、BMI指数高、初潮年龄早、肿瘤家族史、初产年龄大、流产次数多、未产年龄大和行经时乳房涨痛。哺乳和饮用井水是保护因素。

The experiment was conducted to study the effects of digestible energy and true digestible lysine on performance, composition of gestation tissue and hormone levels of primiparous sows during early gestation (mating-on day 84 of gestation), and to find out optimal requirement for energy and Lys content of primiparous sows during early gestation.
本试验旨在研究日粮消化能和真可消化赖氨酸含量对初产母猪妊娠前期（配种～妊娠第84天）生产性能、妊娠物组成和血液激素水平的影响，得出初产母猪妊娠前期能量和赖氨酸的适宜需要量。

This experiment was designed to investigated the effect of energy and lysine content of thediet on maternal body gain, total number born, litter weight, serum biochemical indexes and hormone level, by means of saturation-D best regression design, so as to improve the reproductive performance of primiparous sow and offer theoretical basis for feeding during gestation.
本试验旨在研究日粮消化能(DE，Digestible Energy)和真可消化赖氨酸(TDLys，True Digestible Lysine)含量对初产母猪不同妊娠阶段母体增重、胎儿数、窝重、血液生化指标和激素水平等的影响，为提高初产母猪的繁殖性能以及在妊娠期进行合理饲喂提供理论依据。
