Problems solved by technology

[0014] The above-mentioned technology discloses the breeding method of beaver species or nutria, but mainly provides a series of methods for the selection of nutria, feed mix, site construction, and disease prevention. There is no report involving the breeding method of fragrant beaver species, and currently The species of beaver or nutria in various places are not clear, some are imported from abroad, some are domestic species, and the origin of some species is unclear, and it is not clear whether it is a beaver species or a nutria species. Many individual farms have a single species and long-term breeding , The variety is easy to degenerate, the reason is not scientific breeding, let it be mechanically mixed, biologically mixed, genetic problems of the improved breed itself, and some also use excellent hybrids, but it is not scientific enough. In terms of feed configuration, it is not based on the characteristics of beavers. Preferably, the nutritional content is not suitable, so many individual beaver cultures do not develop
[0015] Furthermore, there is no report in the literature on how to conduct research aimed at increasing the size and quality of beaver sachets (scent glands) and to find out what beaver sachets utilize

Abstract

The invention relates to a breeding method of a scent-gland castor fiber variety. The breeding method comprises the following steps of 1, selecting a castor fiber which is large in size, strong in activity, thick and soft in fluff and robust in a cold region, and selecting a castor fiber domesticated in the south from a Mongolian subspecies and being high in reproductive rate, robust in size, longin tail, large in scent gland, rich in aroma and good in omnivorous fondness for hybridizing; and (2) adopting a pedigree breeding method, performing elimination breeding for a plurality of generations to obtain the scent-gland castor fiber variety which is large in size, good in omnivorous fondness , high in farrowing rate, large in scent gland, rich in fragrance and large and long in tail, performing epidemic prevention treatment, breeding in a zoo or a specific feeding farm, taking the tail as a medical suture line, extracting the scent gland as spice, and using fur.

Description

technical field [0001] The invention relates to the technical field of breeding methods for new animal varieties, in particular to a breeding method for a new beaver variety, the beaver. Background technique [0002] Beaver, Beaver family animal, scientific name: Latin scientific name: Castor fiber , is a family under the beaver suborder. There are only 1 genus and 2 species, one is distributed in North America and Europe, North America is mainly the United States and Canada, Europe is mainly distributed in the Russian Federation, Moldova, Portugal, Turkey, the United Kingdom and other countries; the other is distributed in Asia, mainly In my country's Xinjiang region and Mongolia, the beavers in my country's Xinjiang and Mongolia belong to the Mongolian subspecies of Eurasian beavers, with a narrow distribution and a small number. In China, they are only distributed in the Ulungu River and its upstream Qinggeli River, On both sides of the Burgen River and the Chagan Gol Riv...
