Alpaca liveweight variations and fiber production in Mediterranean range of Chile

Alpaca liveweight variations and fiber production in Mediterranean range of Chile

Journal of range management 51(5): 509-513

A study of liveweight changes of alpaca adult males, females, and their progeny, was conducted through 3 seasons under continuous grazing on natural grasslands on the Mediterranean range of the Chilean Central Zone. Liveweight changes were positive and highest in spring (100 to 200 g day-1), moderate during winter (50 to 100 g day-1), and negative only at the end of summer and in fall (-110 to -150 g day-1). Weight gains of new born alpacas were greatest (110 to 150 g day-1) in the first 90 days after birth and then decreased slightly, reaching values of 75 g day-1 at 8.5 months old. Weight gains stabilized at 10 to 20 g day-1 at 3-years of age. The average annual fibre production was 1.57 and 236 kg in females and males, respectively; staple length varied between 8 and 10 cm.
