Milk samples were obtained at regular intervals throughout lactation from tammar wallabies (M. eugenii). Total solids represented only 12% (w/w) of the milk at the commencement of lactation and gradually increased to about 40% at 36 weeks. Milk proteins represented 4% (w/w) of whole milk during the first 18 weeks of lactation, followed by a rapid increase(More)
1. Milk samples were obtained at various stages of lactation from 16 captive eastern quolls. 2. The mean milk carbohydrate concentration was 7.4% (w/v; total hexose) at 8 weeks post partum, decreasing to 5.2% at 17 weeks and to less than 2% at the end of lactation. 3. The predominant monosaccharide constituent of the carbohydrates was galactose, followed by(More)
Structural characterizations of marsupial milk oligosaccharides have been performed in four species to date: the tammar wallaby (Macropus eugenii), the red kangaroo (Macropus rufus), the koala (Phascolarctos cinereus) and the common brushtail possum (Trichosurus vulpecula). To clarify the homology and heterogeneity of milk oligosaccharides among marsupials,(More)
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(More)
Milk samples were obtained at regular intervals throughout lactation from northern brown bandicoots, Isoodon macrourus, in captivity. Total concentration of milk solids was initially 7% (w/w) and increased linearly to 45% (w/w) by 55 days. Carbohydrate, lipid and protein concentrations increased from about 2% (w/w) to about 7-8% (w/w) at 30 days. Thereafter(More)
1. Milk samples were collected throughout lactation from 10 captive red-necked wallabies. 2. The milk solids content increased throughout lactation and was accompanied by major changes in the relative proportions of protein, lipid and carbohydrate. 3. The carbohydrate fraction consisted of oligosaccharides in the first half of lactation but changed(More)
Blood samples were collected throughout lactation from eight D. viverrinus, and the concentrations of prolactin in the plasma determined by an heterologous, double-antibody radioimmunoassay. For the first 45-50 days of lactation concentrations fluctuated between 2 and 80 ng/ml but were generally less than 60 ng/ml. They then increased sharply to over 120(More)
Milk oligosaccharides were separated from the carbohydrate fraction of milk of the tiger quoll a species of marsupial that is closely related to the eastern quoll, Dasyurus viverrinus. They were characterized by 1H – nuclear magnetic resonance spectroscopy and matrix – assisted laser desorption/ionization time-of-flight mass spectrometry. The following(More)
