The research purpose was the comparative appreciation of different evaluation systems for fur skin
characters and features at Karakul lambs and methods of rams testing by the progeny fur skin
qualities, by emphasizing of those advantages and disadvantages. Research has been done on
breeding sheep from experimental farm of INZMV Maximovca, Anenii Noi district, and CAP
„Agrosargal” from Hânceúti district. As a result of research has been found, that, the category of
rams amelioration obtained as a result of the application of the terminological system of fur skin
characters and features assessment at lambs appreciation and of simple testing method by the
progeny fur skin, will not be afterwards confirmed, in proportion of 85%, when the decimal system
of scoring is applied in order to appreciate the characters and features of lamb fur skins and will be
used the biometric method of scoring, by testing the rams after the progeny fur skin qualities.
Moreover, some rams that were qualified as reducing (worsen), as a result of testing after the
progeny fur skin qualities by the simple method, have become ameliorator breeders, as a result of
their testing after the biometric scoring system of progeny fur skin qualities and, reverse, other
rams, which were qualified as enhancers in testing result by simple method, became reducers, as a
result of their testing by biometric scoring method. It was concluded, that only application of
terminological system assessment of Karakul lambs and of the simple method of rams testing after
the progeny fur skin qualities are not enough for an objective evaluation of breeders amelioration
category. The conclusions made as a the result of testing with simple method application are offen
unreliable and contradictory, The use of decimal scoring system at Karakul lambs assessment and
of biometric scoring method at testing rams after the progeny fur skin qualities, permits objective,
genotypic evaluation of breeders amelioration category by determining the certainty criterion of the
conclusions regarding amelioration degree of each ram apart. As a result of research was proposed
a classification of Karakul rams by the amelioration value in following categories: I degree
ameliorator – whose progeny exceeds by score ranking, the flock level with td ? 3.3 (B ? 0.999). II
degree ameliorator - whose progeny exceeds by score ranking, the flock level with td ? 2.6 – 3.2 (B
? 0.99). Ordinary ameliorator - whose progeny exceeds by score ranking, the flock level with td ?
2.0 – 2.5 (B ? 0.95). Relative ameliorator - whose progeny exceeds by score ranking, the flock level
with td ? 1.6 – 1.9 (B ? 0,90). Neutral – whose progeny doesn’t have a certain positive difference
comparing to flock level. Certain reducer – whose progeny surrenders by score ranking, the flock
level with td ? 1.6. Relative reducer - whose progeny surrenders by score ranking, the flock level up
to td <.1.6.
