title: [Genetic characteristics of the 1st Soviet miniswine, Minisibs (miniature Siberian swine). I. The breeding of Minisibs and their morphophysiological properties].
abstract: The first form of laboratory mini-pigs "Minisibs" (miniature siberian swine) in USSR is the result of the distant hybridization and of the system of complex crosses between domestic and wild pigs of European and Asiatic origin (Sweden Landrace, Black Vietnamese, Sus scrofa ferus, Sus scrofa nigripes). "Minisibs" have a very small size, their live weight at birth is 517.16 +/- 6.48 g, at the age of two months--4.72 +/- 0.13 kg, at the age of 6 months when sexual maturity is achieved--19.02 +/- 0.89 kg and at the age of 12 months when they are adult males--29.75 +/- 2.98, females--35.35 +/- 0.01 kg. More than 88% of "Minisibs" are white, they have calm behaviour, are omnivorous, tolerant to a wide range of ecological conditions. "Minisibs" have a set of immunogenetical and cytogenetical features, in which they differ from other known miniature pigs. One of these features is the chromosome polymorphism: "Minisibs" have a 2n = 38, 37 and 36 karyotypes. "Minisibs" are very similar to a man in morphological and physiological parameters of many organs, and in the course of various pathological processes. For these reasons, mini-pigs "Minisibs" can be efficiently used as the best adequate model in the large scope of medical and biological programmes.
