Male and female Karakul sheeps were weighted from birth to the seventeenth month of age, at intervais of thirty days. At birth, the average weight was 5.00 kg, with a stan- dard deviation of 0.55 kg. No significant differences were observed between males and females, through-out the 18 weightings. Under the experimental conditions, the growth curve can be represented by:
^Y = 4.346 + 0.4184 X - 0.00323 X² + 0,00000984 X³ - 0,94725 E^-08 X⁴
where:
^Y= estimated weight
X = weight in days.
