Summary. The article presents the results of studies on the dynamics of live weight and down productivity of goats of Orenburg breed and crossbreeds with the Don breed. The aim of work was to obtain new experimental data on the indicators of down productivity improving goats of Orenburg breed. For the study, 3 groups of goats with 20 heads in each were formed: group I – purebred grey, II – purebred white, group III – crossbred of the 1st generation white Don×Orenburg white. Control rearing lasted from birth to 30 months of age. It was established that grey and white goats of Orenburg breed have an advantage in live weight during all periods of growth over cross-breed peers of group III. Peers of group II at all stages of live weight control are characterized by an intermediate severity of trait.

According to fleece and true length of down, goats of group III are superior to peers of groups II and I, but have a coarser down, which is in group I by 3.20 µm (P≤0.001), and in group II by 1.8 µm (P≤0,05) thinner than that of peers of group III.

Key words: grey goats, white goats, Orenburg breed, live weight, fineness, length, fleece, downy goat breeding.
