Abstract :
An experiment based on males from 20 llama and 40 alpaca reared in Peru evaluated the carcass characteristics from animals
slaughtered at 25 months of age, at a final body weight of 46.1 kg for alpaca and 63.2 kg for llama. Warm carcass weight was
significantly higher in llama carcasses compared with alpaca, while dressing percentage was higher in alpacas. In the llama
carcasses, leg, thorax and chops were heavier compared with the same cuts taken from the alpaca carcasses (P < 0.05). In
contrast, the shoulder and neck were proportionately heavier in the alpaca compared with the llama carcasses. Full digestive tract
was the heaviest component found in the carcasses. In the llama carcasses, both full digestive tract and digestive content were
significantly heavier than in the alpaca carcasses. Significant differences were observed in the proportion of muscle and bone
in the shoulder and in the leg of the llama and alpaca carcasses. Llama and alpaca slaughtered at similar age showed different
carcass characteristics; considering the results of this study, llama can be more easily bred as animal for meat production.
