Abstract

Divergence analysis of performance of Karakul and its crosses and development of Indian Karakul.

Abstract

Data on 2446 lambs were analysed. For Karakul purebreds and crossbreds with 75% Karakul and 25% Malpura, Sonadi or Marwari breeding (Indian Karakul, IK), birth weight averaged 3.49 and 3.35 kg respectively (P<0.01), weaning weight 12.95 and 13.65 kg and greasy fleece weight (2nd clip) 577 and 526 g (both P<0.05). The percentage of jacket-type pelts was 58.43 and 47.71 and that of sheep with black coat colour 98.77 and 95.06, pelt weight averaged 174.3 and 160.3 g, and lamb mortality from 16 to 90 days of age was 14.35 and 7.54%. There were no differences between the 2 breed types in pelt length or width, body weight at 6 or 12 months or mortality from 0 to 15 or from 91 to 180 days. For IK lambs, the h2 of birth weight, weaning weight, body weight at 12 months, pelt type score, pelt colour, pelt width and pelt weight were 0.53, 0.31, 0.31, 0.04, 0.12, 0.47 and 0.05 respectively, and the heritability of greasy fleece weight in the 1st and 2nd clip was 0.28 and 0.21.
