Following a small survey of milk constituents in 5 lactating alpacas in south-eastern Australia, it was revealed that the average milk fat content was 4.4%, the average milk protein content was 4.2% and the average milk sugar (lactose) content was 5.8%. Constituents in alpaca milk can vary depending on age of dam, number of days post-partum, nutrition and genetics. Accordingly, alpacas and llamas exhibit small ranges for milk fat (2.7-4.9%), milk protein (3.4-4.5%) and milk sugar (lactose; 5.6-7.4%) in the scientific literature.
