title: Milk composition in the plains viscacha (Lagostomus maximus).
abstract: Milk samples were taken from 10 plains viscacha between 9 and 64 days post partum. Mean concentrations (+/- s.e.) were 17 +/- 1.1 mM-Na; 32 +/- 1.6 mM-K; 35 +/- 2.2 mM-Cl; 116 +/- 3.3 mM-lactose (total reducing sugar) (all in 8 samples); less than 10-220 mg citrate/l (range of 4 samples); 15.7 +/- 0.64 g total nitrogen/l (3 samples). The Na:K ratio was 1:1.95 +/- 0.17. It was estimated that the fat concentration was between 116 and 182 g/l.
