There were considerably interspecies, individual, lactation and age related variabilities in the concentration of spermidine and spermine in cow's and sow's milk. Concentration of spermidine was similar in cow's and sow's milk, whereas spermine level was higher in sow's milk. The level of spermine was higher than spermidine throughout the lactation in sow's milk, whereas spermine in cow's milk was secreted only at the beginning of lactation (collostrum and milk of the first month of lactation). The peak of spermidine and spermine concentration occurred in the collostrum and milk between the 1st and 3rd week of lactation in cow and sow, respectively. There was a significant positive relationship between milk yield and spermidine secretion in cow as well as between the number of piglets and milk spermidine concentration in sow.
奶牛和母猪乳汁中精胺和亚精胺的浓度存在显著的种间、个体、泌乳期和年龄相关差异。奶牛和母猪乳汁中亚精胺的浓度相似，而母猪乳汁中精胺的水平更高。在母猪整个泌乳期，精胺水平高于亚精胺，而奶牛乳汁中的精胺仅在泌乳初期（初乳和泌乳第一个月的乳汁）分泌。奶牛和母猪乳汁中亚精胺和精胺浓度的峰值分别出现在泌乳第1至3周的初乳和乳汁中。奶牛的产奶量与亚精胺分泌之间以及母猪的仔猪数量与乳汁中亚精胺浓度之间存在显著的正相关关系。
