Abstract

Performance improvement in Hycole, Hyla and NZW rabbits was carried out through selection criteria for annual productivity index (IPa) and body weight at 63 days of age. Breeding of the first generation of broodstock (G1) produced 300 offspring which were selected based on the IPa value of the best 50% of the prospective broodstock and the body weight of 63 days of age which was 10% of the best male candidate. Selection criteria for body weight of 63 days in Hycole and NZW rabbits are still quite effective and can be continued because each of them still provides a fairly high coefficient of variation, 22.05% and 23.13% respectively in G2 selected rabbit. The decrease in body weight at the age of 63 days in Hycole G1 to G2 rabbits from 903.26 to 870.14 was thought to be due to changes in environmental conditions. The selection criteria for the annual productivity index in Hycole and NZW rabbits can still be done because the variation is still high, reaching 27.90% and 23.26%, respectively.
