Straw nutria

Having tamed one such animal as nutria and started to plant it for industrial purposes, a person eventually realized that it is possible not only to grow and breed a swamp beaver (also called nutria), but also to conduct selective experiments with it. After all, as a result of the latter, nutrias are obtained with pelts of various shades and colors, and such fur is much appreciated much higher than the standard brown-brown fur

In total, about 20 new breeds of black, white, golden, silver, beige, cream, brown and other colors were removed during the experiments

One of the species is straw nutria. In addition to color, it has one more important difference from other “products of breeders’ activity”. The vast majority of color nutria are bred for fur. A straw nutria is needed only to derive new varieties of rocks. It does not make fur coats, hats, or collars. She is not even allowed to eat meat. It serves exclusively as a genetic material for breeders in the process of creating colored rocks

Thus, for example, by crossing the straw nutria with black in 1968, the employees of the Severinsky ZV have obtained a pastel rock of nutria, which is quite popular today. You can recall other examples

The very “slab”, as it is affectionately called amateur livestock breeders and professional breeders, is the result of the cleavage that occurs in the process of breeding standard nutrients

The color of the straw of the straw nutria is yellow-brown with light brown and brown hues. The younger the animal, the lighter it is. With age, the yellowish-brown color becomes darker, brighter and more expressive

According to the constitution and many other parameters, straw nutria almost does not differ from its standard products. She has the same body structure of 45-60 cm in length and the same tail, occupying almost half of the total length (about 30-40 centimeters). The incisors of young healthy individuals are orange, and in young animals and elderly animals they are almost white. The eyes are also brown, and the vibrissae are white. The nose is the same color as the nutria that live in the natural environment

Not inferior to straw nutria standard and in fertility. Usually the female brings 4-5 calves per litter. The number of litters a year ranges from two to three. Puppies are born sighted, viable, from the first minutes of life they can move independently and like to do it, grow and develop rapidly. Within ten days after birth, they drink mother’s milk, and then switch to solid, mainly vegetable fodder

Straw nutria, like their relatives of the standard breed, swim well and can be underwater long enough (up to five minutes). They are afraid of too much heat and strong frost, preferring an average air temperature (15-20 degrees Celsius)

In fact, their only difference is the color of the fur coat. Which did not appeal to the consumers of fur and prepared the straw nutria for an intermediate role in the chain of breeding achievements

In the pure form of straw the nutria is not bred. And although the “Severinsky” zhirosovkhoz has long been absent, the livestock breeders of other enterprises of the country and just amateurs use this recessive kind of colored nutria for breeding new, interesting breeds. Today we can say thanks to “straw”, for example, for “pastel”. And there are still a lot of varied variations ahead!
