Alpacas are browsers rather than grazers. They thrive on a high fibre/low protein diet. They do well on native grasses. They like hay and silage. Supplementary feeding of grains, legumes and/or alpaca nuts are enjoyed by feeding mums or any animals needing to increase their body score.
The alpaca is a modified ruminant with a 3 compartment stomach. It converts grass and hay to energy very efficiently, eating less than other farm animals.
Fresh drinking water must be available at all times. In summer an alpaca may drink up to 4 litres per day.
