In canines and mustelides total vitamin A was 10-50 times higher compared to other species due to a high amount of retinyl esters (40-99% of total vitamin A) in blood plasma. The dominant vitamin A ester was in most species retinyl stearate. 2. In Ursidae, Procyonidae, Viveridae and Felidae, total vitamin A was much lower. When present, however, retinyl esters also represented 10-65% of total vitamin A in plasma. 3. Only retinol was detected in plasma of the family, Hyaenidae, and the suborder, Pinnipedia. 4. In maned wolf cubs it was found that retinol, retinyl esters and alpha-tocopherol increased with the age of the animals, reaching values comparable to adult animals at the age of 5 months.

在犬科动物和鼬科动物中，由于血浆中视黄酯含量很高（占总维生素A的40%-99%），总维生素A比其他物种高10-50倍。在大多数物种中，主要的维生素A酯是硬脂酸视黄酯。2. 在熊科、浣熊科、灵猫科和猫科动物中，总维生素A含量要低得多。然而，当视黄酯存在时，它在血浆中也占总维生素A的10%-65%。3. 在鬣狗科和鳍足亚目动物的血浆中只检测到视黄醇。4. 在鬃狼幼崽中发现，视黄醇、视黄酯和α-生育酚随动物年龄增长而增加，在5个月大时达到与成年动物相当的值。
