Marma B.B.and Yunchis V.V. (1968). A contribution to biology of the Snow-leopard (Panthera uncia uncia) (by observations in captivity) (Vol. XLVII, issue 11.).
Abstract: The methods to obtain the progeny of the snow leopard (Panthera uncia uncia) in captivity were being elaborated in the zoological garden of Kaunas, Lithuanian SSR. The blood characteristics for snow leopards is given and compared to that for African lions and Sumatrian tigers. A series of internal, external and clinical indices is established. The rat lasts for 5-7 day, the duration of pregnancy equals 98 days. The duration of lactation varies from 3 to 4 months. Sexual maturity is attained on the 3rd-4th year. From 1960 to 1967 in zoological garden of the world about 29 snow leopards were born, 14 of them in the Kaunas zoological garden.

Abstract: Reintroduction and captive breeding are often touted as panaceas for extinction in the wild. The populace at large, educated insuch matters by the mass media, places great faith in such wildlife technology. Furthermore, the wildlife professionals who develope recovery and managemnt plans for endangered species often include a section on reintroduction and sometimes advocate captive breeding as a source of colonizing stock.
