Marsupials, such as the tammar wallaby (Macropus eugenii), have adopted a reproductive strategy that is very different to eutherians. Both the rate of production and the composition of milk changes progressively during the lactation cycle to meet the nutritional demands of an altricial young. The tammar therefore provides a valuable model to study changes in milk composition, and in particular the genes that code for proteins secreted in the milk, to more accurately assess the role of gene products regulating either development of the young or mammary function.
有袋类动物，如短尾矮袋鼠（Macropus eugenii），采用了一种与有胎盘类动物截然不同的繁殖策略。在泌乳周期中，乳汁的分泌速度和成分都会逐渐变化，以满足早产幼崽的营养需求。因此，短尾矮袋鼠为研究乳汁成分的变化，尤其是编码乳汁中分泌蛋白的基因，提供了一个有价值的模型，以便更准确地评估基因产物在调节幼崽发育或乳腺功能方面的作用。
