Abstract

The article presents data on the studied dynamics of live weight of plant-type lambs of the Kyzylkumtupe from birth to 4 months of age compared to black colored lambs. The data summarized in the table show that there are certain differences in terms of live weight between colors. Moreover, higher rates, although they are statistically unreliable, are observed in black lambs at birth. Such differences in lambs of a semi circular curlicue type are 0.05 kilograms, ribbed type 0.08 kilograms, flat type 0.11 kilograms, over grown type 0.17 kilograms, and a weighted average of 0.09 kilograms. The same trend is observed at 4 months of age. Moreover, higher rates, although they are statistically unreliable, are observed in black lambs at birth. Such differences in lambs of a semi circular curlicue type are 0.05 kilograms, ribbed type 0.08 kilograms, flat type 0.11 kilograms, over grown type 0.17 kilograms, and a weighted average of 0.09 kilograms. The same trend is observed at 4 months of age. However, it should be noted that the slightly low live weight of sura lambs does not say that they are to some extent under developed. The performance of these lambs may well provide them with a sufficiently high vitality and productivity.
