Gene
Protective PRNP variants make classical scrapie much less likely, but not impossible. Each goat has two copies of the gene; VGL reports two positions on it (codons 146 and 222).
Each copy shows its own effect, so both can be seen together.
DNA studies support S146, D146 and K222 as protective PRNP variants. A protective copy makes classical scrapie much less likely; it is not scrapie-proof. US rules still treat exposed goats as susceptible.
VGL reports codons 146 and 222 separately. Read a double heterozygote such as N/S, Q/K assuming the two protective variants are on different copies. If both were on one copy, only half the kids would receive a protective copy. Keep the lab's wording. Any other codon combination doesn't match known haplotypes; check the report. The "no tested variant" haplotype is N146/Q222; it can still carry variants such as M142, Q211 or H154 that this model does not represent. Only S146, D146 and K222 are treated as protective here. Record a report with no protective variant as absent (No protective PRNP variant), keeping VGL codons 146/222 as its test scope. In a US study of 6,029 goats, resistant codon 146 genotypes occurred in Boer 47.0%, Nubian 38.6%, LaMancha 35.8%, Nigerian Dwarf 0.7% and Pygmy 0.6%. K222 occurred in Toggenburg 22.0% and Oberhasli 23.1%. These sample frequencies do not predict an untested goat.

Guides and articles for Scrapie Resistance (PRNP) goat owners.
A goat itself usually costs somewhere between $150 and $800, and where a given animal lands in that range depends almost entirely on what it is for. A pet wether (a castrated male) is the cheapest, often $150 to $350, because he has no breeding or dairy value. A grade dairy doe or a commercial […]
Feed goats a diet built on forage and browse, with good hay as the year-round backbone, and add grain only when a specific animal actually needs it. Goats are ruminants, so their whole digestive system is designed to ferment long-stem fiber, not to run on concentrates. Get the forage right, keep clean water and loose […]
The goat gestation period is about 150 days (145 to 155). Use our kidding date chart, Boer, Pygmy and Nigerian Dwarf notes, and free calculator.
A doe shared a paddock with a buck, but nobody saw the service. That is useful information, provided the record says exposure rather than inventing an exact mating date. The same distinction matters when two bucks were present or a later veterinary estimate changes your planning window. Creatures lets you record breeding events and track […]
A goat that is fed well, wormed sensibly, and never culled will usually live into its low-to-mid teens. Washington State University Extension teaches 10 to 15 years as the average for the species, and the captive-longevity record compiled in the AnAge database puts the verified maximum at 20.8 years, held by one female, with a […]
Set up a farm tour by defining the visit before opening the calendar: who it suits, what guests will do, how many people you can host, what the price covers, and how arrival works. Creatures can turn that plan into dated bookable sessions. The bookable-offering guide shows where to create the draft and finish its […]
