哺乳是哺乳动物母亲产后最大的能量消耗，母亲承受哺乳费用的能力受其身体状况的影响。与条件差的母亲所生的婴儿相比，条件好的母亲所生的婴儿体重更重，生长更快，存活的可能性更大。这些影响可能部分通过母亲在哺乳期间产生的乳汁的数量和质量来介导。然而，我们对产妇状况、乳汁成分、产奶量和婴儿结局之间的关系知之甚少。在这里，我们提出了第一个系统的调查的幅度，来源和后果的个别变化，牛奶的旧世界猴。恒河猴产生稀释的牛奶典型的灵长类目，但有很大的差异，母亲之间的组成和数量的牛奶，他们产生的，因此在牛奶的能量提供给婴儿。相对产奶量值（MYV），即母婴分离3.5-4小时后乳房排空获得的牛奶克数，随着产妇产次的增加而增加，并与婴儿体重正相关。乳总能量（GE）和MYV在哺乳期随着婴儿年龄的增长而增加。然而，这是一种权衡; GE增加较多的母亲的MYV增加较小，而她们的婴儿生长较慢。这些结果从一个喂养良好的圈养人口表明，母亲之间的差异可以有重要的影响，母乳合成和婴儿的结果。
Lactation represents the greatest postnatal energetic expenditure for mammalian mothers, and a mother's ability to sustain the costs of lactation is influenced by her physical condition. Mothers in good condition may produce infants who weigh more, grow faster, and are more likely to survive than the infants of mothers in poor condition. These effects may be partially mediated through the quantity and quality of milk that mothers produce during lactation. However, we know relatively little about the relationships between maternal condition, milk composition, milk yield, and infant outcomes. Here, we present the first systematic investigation of the magnitude, sources, and consequences of individual variation in milk for an Old World monkey. Rhesus macaques produce dilute milk typical of the primate order, but there was substantial variation among mothers in the composition and amount of milk they produced and thus in the milk energy available to infants. Relative milk yield value (MYV), the grams of milk obtained by mammary evacuation after 3.5–4 h of maternal-infant separation, increased with maternal parity and was positively associated with infant weight. Both milk gross energy (GE) and MYV increased during lactation as infants aged. There was, however, a trade-off; those mothers with greater increases in GE had smaller increases in MYV, and their infants grew more slowly. These results from a well-fed captive population demonstrate that differences between mothers can have important implications for milk synthesis and infant outcome.
