From Sunset chins
Brevicuadata Chinchillas were brought into the US and have been mixed into herds several times in the 60's, 70's and 80's. They most often created sterile F1 hybrids but like any cross some were fertile and continued on. The photos are of known pure Brevi.
The traits we see passed in modern herds today;
-Much thicker and denser skeletal structure, wider body and thick short tail.
-Slower production rate of 1-2 babies once or twice a year.
-Extremely long production lifespan (15-20 years)
-Immense size with age, maturing at 5-6 and over 1,000g *not fat*
-Poor Lactation, only able to raise one or two at a time.
-Cycle less frequently than animals with less influence
-In production herds; longer gestation times, regularly go to 115+ days to litter.
Like any genes you can focus on one and mix/match over generations so there is quite a variety.
In the wild they have their own preserve; https://peakvisor.com/park/reserva-provincial-alto-andina-de-la-chinchilla.html and this information comes from the breeding program that was established there.
Gestation: 128 days
Size: 550-850g wild caught, up to 1000g observed in captive non-pregnant animals.
Tail is roughly 1/3 the body length with only 20 vertebre.
Vs. Lanigera
Gestation: 111 days
Size: 300-400g in the wild, up to 650g captive.
Tail: 3/4 to length of body with 23 vertebre
In modern herds can produce and feed 3-4 litters per year totaling 9-12 babies.
