Introduction to the Characteristics of the Danish Red-Eyed White Mink Breed
The Danish Red-Eyed White Mink was introduced from Denmark in 1998. It has a relatively large body size and brightly colored fur, giving it high economic value. Domestic mink breeding stock and product quality are poor. Apart from the direct cause of breeding stock varieties, this is also related to the lack of scientific feeding techniques. Common problems in domestic mink farming include insufficient feed input, incomplete nutritional supply, poor breeding environments (such as no sheds, no small dens, unsanitary feed environments, etc.), and poor pelt-removal techniques. Mink farmers must improve the above shortcomings and produce high-quality fur

What is the Jilin white raccoon dog? An introduction to the breed characteristics of the raccoon dog
The Institute of Special Animal and Plant Sciences of the Chinese Academy of Agricultural Sciences used the mutant white gene found in the wild coat color (common color type) and, after 16 years of research, finally succeeded in breeding our existing new color type white raccoon dog, the Jilin white raccoon dog. In terms of phenotype, the new color type white raccoon dog has two forms: one retains the wild-type coat color only around the eye rims, ear edges, nose tip, claws and tail tip, while the guard hairs and underfur on all other parts of the body are pure white; the other has pure white guard hairs and underfur on all parts of the body. The two white raccoon dogs are the same as the wild-type raccoon dog in body shape, appearance, habits, reproductive capacity and so on; they are docile in temperament, prone to obesity and relatively heavy in body weight.

Detailed introduction to the new oyster mushroom variety Nongke No. 5
The new oyster mushroom strain, Nongke No. 5, was bred by the Chinese Academy of Sciences. The Wuhe Edible Fungi Research Institute of Anhui Province introduced it for demonstration cultivation in August 1998. Through 3 years of multi-site comparative trials, it showed extraordinary superior traits. This mushroom has thick flesh, a short stalk, a round and regular cap, smooth and glossy, with a very strong fresh appearance, delicate and delicious flesh, extremely tolerant of CO2, and a soft yet firm fruiting body. It thus overcomes the drawback of conventional varieties being easily broken during long-distance transport. When the outside temperature drops below 15°C, the cap is even blacker than black wood ear, making it a typical black food at present.
