Stud owner Lance Trigg said it was the third time since 2003 Nambi had marked Australian Alpaca Week with open farm days.

He said they did it to open people's minds to another avenue of livestock production.

"They're so good on the environment because they don't compact the earth as much as sheep," he said. 

"Their fleece is very much wanted - the Peruvians call it the fibre of the gods." 

Mr Trigg said the open days provided information about fleece quality and animal husbandry, as well as children's activities.

Nambi Alpacas joined forces with Haven Alpacas for the open days.

"It's something very worthwhile, with alpaca numbers growing across Australia," he said.

"It's an avenue for people to open up and realise that beyond a pretty face, they have uses in the fleece. We also have a big team we lease out for protecting lambing ewes."

Mr Trigg said he had a team of about 80 animals available for lease.

"Instead of buying them, farmers can lease them for the lambing down period," he said.

"They bring them in about two weeks prior to the ewes lambing down, and then keep them there until the tailing is done. 

"They find generally there's a greater increase in live lamb to market ratio."

Mr Trigg said although modest numbers attended the first of the two days on Saturday, he hoped less competition from other events would bring more people through the gate at the weekend.

He said the open farm day would kick off at 80 Horsham-Lubeck Road, Riverside from 10am Saturday.
