A fleece histogram summarizes measurements from a submitted sample, commonly including fiber diameter, variation, and the distribution of coarser fibers at that point in the animal's life.

A focused breeding program
Selection centers on measurable fleece traits
Colusa Riverside Alpacas raises Huacayas in Lincoln, in the foothills northeast of Sacramento. The ranch concentrates on white and light breeding stock, combining visual evaluation with fleece measurements and genetic information as it plans pairings and considers animals for sale.
Its emphasis is more specific than that of a general visitor farm. Within the collection of California alpaca farms, Colusa Riverside is particularly relevant to breeders comparing the documented fiber potential of alpacas, including males, females, offspring, and extended family lines.
Three forms of evidence
No single number describes a breeding animal
An Expected Progeny Difference estimates how an animal may influence specific traits in its offspring relative to a larger evaluated population. Accuracy and the trait being measured both matter.
Pedigree, offspring, age, reproductive history, show results, conformation, health, and repeat fleece testing add context that one year's measurement cannot supply on its own.
White Huacaya genetics
The ranch follows fiber traits across generations
Colusa Riverside describes a long-term program built through selective breeding and the purchase of animals that complement its goals. White fleece allows fiber structure and uniformity to be assessed without color variation becoming the central feature of the program.
Current herd information highlights traits such as fineness, density, staple length, uniformity, and the ability to retain desirable fleece characteristics with age. The ranch publishes supporting records for selected animals so prospective buyers can examine the basis for a breeding claim rather than relying only on a short description.
Breeding males
Herdsire pages may include ownership status, stud availability, offspring, show records, histograms, EPDs, and supporting documents.
Female lines
Proven and unproven females are considered through their own measurements as well as ancestry, prior offspring, breeding status, and planned pairings.
Current livestock listings
Animals can fill different roles
Listings change as animals are bred, retained, sold, leased, or moved into another category. Confirm the current status and supporting records directly with the ranch.
01
Foundation females
Open and bred females may be offered for buyers developing a breeding herd. Their value depends on the complete animal, not simply coat color or one favorable statistic.
02
Herdsires and breedings
Selected males may be available through a full or partial ownership sale, lease, or outside breeding. Each arrangement has different rights, responsibilities, and veterinary requirements.
03
Fiber and companion alpacas
Not every alpaca needs a breeding role. Fiber or companion placements can provide suitable herd mates while allowing fleece to remain a useful annual product.
Stay on the property
Ranch lodging is a separate experience
The farm's website includes information about overnight accommodations near the alpacas. Lodging availability, animal access, house rules, and booking terms should be reviewed through Colusa Riverside's own page before making plans. This profile does not link directly to a third-party rental platform.
Fiber in finished form
The ranch store has featured alpaca rugs
Product listings show handwoven alpaca area rugs in natural and mixed colors. Individual pieces may be one of a kind, previously sold, or unavailable, so the current store should be checked rather than assuming a pictured rug remains in stock.
Independent Alpaca Farms guides
Put fleece measurements and color in context
These educational guides are published by Alpaca Farms. They are independent of Colusa Riverside Alpacas and do not evaluate its animals, genetics, EPD results, histograms, sale terms, or products.

Use individual listings for current decisions
Visit the official website for available alpacas, ownership and breeding arrangements, pedigrees, fleece data, EPD documents, product inventory, ranch-stay information, and direct inquiries.
Profile information was reviewed against Colusa Riverside Alpacas' official website and current industry listing in September 2026. Animals, ownership shares, breedings, EPD results, fleece records, prices, products, and lodging arrangements can change; confirm current details directly with the ranch.
