I don’t know what alpaca meat tastes like, but if it’s anything like goat meat, and if rearing costs are similar, you could attempt to sell it as an upscale goat meat substitute to ethnic communities in surrounding states. West Indians, South Asians, Africans and many Muslim communities are partial to goat meat - and therefore, perhaps close substitutes - although for Muslim communities, you might need halal (similar to kosher) certification from some local Muslim religious figure.
Not a bad idea and we, (the Industry), have looked at it. Unfortunately biology comes into play there. The Average Alpaca weighs between 135 and 180 pounds. They live for around twenty years and get to maturity in three years. The average Gestation time is eleven and half months to a full year. There is one Cria, (baby), at a time. So herd growth is necessarily slow.
Goats on the other hand can have two birthings a year usually of twins and the grow quickly to maturity. A four to one advantage when producing meat animals or herd growth.
As a type of livestock that has been bred for a specific purpose over 5,000 years, (so I am told), they are admirably suited for producing fiber, (hair, fleece, what-have-you), that is of a quality that is simply amazing for it’s softness, strength, warmth and generally all the good qualities that humans look for in fiber to make into clothes. That means that to make them a meat animal would be to the detriment of their fleece because you want to fatten them up and put on the poundage, which all leads to degraded Fiber production.
