The milk of the fur‐seal, Arctocephalus tropicatis gazella; in particular the composition of the aqueous phase

摘要: Milk and plasma samples from the Southern fur-seal (Arctocephalus tropicalis gazella), collected animals shot between 0 26 days post-partum, have been analysed. The aqueous phase of milk (ultracentrifugate) was hyperosmotic to by about 35 m-osmol/kg water but contained no lactose. osmolality could be accounted for ionic content, which sodium potassium (in approximately equal amounts) were main cations. fat content very high (approximately 40%), except in early lactation (0 1 day post-partum). concentrations chloride, calcium, magnesium, phosphate citrate are given. Major differences composition that other mammals pointed out, discussed relation conservation, energy supply, prolonged storage this snecies.
