EVALUATION OF KARAKUL LAMB BY PHENOTYPE IN CASE OF A LARGE NUMBER OF BREEDING TRAITS
Methods for assessing krimmer lamb productivity, constitutional and reproductive characteristics used in Karakul sheep breeding have been studied. It has been established that there are several dozens of krimmer breeds, except karakul, as well as crossbreeds with them, from which karakul is also obtained in the world. Sheep selection of these breeds differs significantly from selection of other breeds by the fact that decisions on animal production purpose are made as soon as this animal is born. The selection is carried out according to a large number of characteristics, mainly parameters of krimmer lamb skin quality. Such techniques are numerous and have certain differences in different breeds and different countries, however, there are also common properties. Most of the selection parameters are determined subjectively, and the only decision is made - whether to leave the lamb for breeding or to remove the krimmer. Obviously, a method is needed which includes all the selected traits and it would be expressed in one complex parameter. In the course of this study, a new, suitable for automation method for increasing the objectivity of phenotype assessing of Karakul sheep by a complex of traits was designed and described. Specifically, a special card is proposed and shown in the appendix, which facilitates the collection of individual data from a newborn lamb and their processing using spreadsheet application. From our own observations and production experience, the practicability of obtaining marketable milk from krimmer sheep, free from suckling lambs, is shown. Folk traditions of improving sheep milk yield that exist in sheep-breeding countries are described. Examples of successful use of Romanov sheep on karakul ewes and creation of multiparous karakul on their basis are shown.
