The milk constituents of Dasyurus viverrinus, a carnivorous marsupial, exhibited major quantitative and qualitative changes during the course of lactation. The milk produced in the early stages of lactation was dilute, about 13-16% (w/w) solids before 3 weeks with carbohydrate representing the major fraction. In the latter stages of lactation the milk was concentrated, around 30% solids, and lipid was the predominant fraction. Palmitic acid was the major fatty acid present in early-stage milk but oleic acid became predominant in milk after 10 weeks post-partum. The changes in milk composition in D. viverrinus were similar to those described for the milks of herbivorous marsupials which therefore suggests that this pattern may be uniform throughout the Marsupialia.
袋鼬属的肉食性有袋动物——帚尾袋鼬的乳汁成分在哺乳期会出现主要的定量和定性变化。哺乳期早期分泌的乳汁较为稀薄，在3周龄前，其固体成分约为13%-16%（重量/重量），其中碳水化合物占主要部分。在哺乳期后期，乳汁变得浓稠，固体成分约为30%，脂质成为主要成分。棕榈酸是早期乳汁中的主要脂肪酸，但产后10周后，油酸在乳汁中占主导地位。帚尾袋鼬乳汁成分的变化与食草有袋动物乳汁的变化相似，因此表明这种模式在有袋类动物中可能是一致的。
