There has been much discussion in the alpaca world about blue-eyed white alpacas. Some breeders believe that blue eyed white alpacas should not be allowed to reproduce, others feel that at least the female blue eyed white alpacas should be allowed to breed but that they should be bred to solid dark alpacas to reduce the risk of reproducing another blue-eyed white alpaca, and other breeders do not perceive blue-eyed alpacas as a problem and use them in their breeding program.
If you search for “blue eyed white alpaca” on the Internet your search terms will guide you to a few articles written on blue-eyed white alpacas. One of the concerns with blue-eyed white alpacas is that they may be deaf, certainly it seems that some are but not all blue-eyed white alpacas are deaf.
One question I have is how much of the light blue or white pigmentation needs to be present in an alpaca’s eye to determine that a white-coated alpaca is a blue-eyed white?
We have two boys on our farm that have lighter coloring in the iris of their eye in addition to the darker coloring of the iris (I did discover during my research for this entry that the term for an iris that has greater than one color between and/or within each eye is called heterochromia). One of the boys has a white fleece although it is more of a creamy white than a true white; he has a little under 25% of his iris as blue or white. The other boy has white/light streaks over less than 10% of his eyes surface, his fleece is beige. Both boys are out of the same dam but have different sires.
The dam of these two boys has a white fleece and very dark eyes; she has produced crias before ranging from medium fawn to white.
I would love to figure out what the genetic possibilities are for this dam in regards to fleece color and eye color. After she produced the first boy with light blue in his eyes, we did some research and decided that we should breed her to a dark fleeced alpaca with dark eyes. We did that and ended up with a beige alpaca with a little white/light blue in his eyes.
So where do we go next with this girl if we wish to avoid the lighter coloring in her crias eyes? I wanted to breed her to a fawn male to see what would the result would be but when we tried that breeding combination she repeatedly rejected that male, so we ended up breeding her to a different male who is white, but is out of a fawn dam.
I think while we are waiting for this girl to have her cria I will get in touch the authors of articles on blue-eyed white alpacas and seek their opinion on the best choice of herdsire for my girl. I will also be asking if my two boys are really considered blue-eyed whites. If I get a reply I will let you know what they say.
