Abstract

Selection based on weaning weight in Rex, Satin rabbits and their crosses was done to improve its productivity. Data from the base population (P0), selected population (G0) and an offspring of selected population (F1) were used to estimate heritability using nested analysis method (nested) and best linear unbiased prediction (BLUP). The value of heritability estimated of birth weight, weaning weight, 12 weeks body weight and 16 weeks body weight of Rex were 0.74±0.09, 0.93±0.05, 0.81±0.09 and 0.89±0.06, Satin were 0.96, 0.82±0.22, 0.93±0.40 and 0.97 and Reza were 0.96±0.27, 0.98, 0.86±0.40 dan 0.78, respectively. Increase in weaning weight on selected Rex, Satin rabbits and their corsses were 22.77 g (3.66%), 6.83 g (1.11%) and 65.29 g (10.67%). Key Words: Selection, Rabbit, Heritability, Weaning Weight

Abstract

Rabbit productivity in intensive management to be evaluated considering development in the rabbit farming were rapidly increased. Rex, Satin and their crossbred (Reza) rabbits have been developed in Research Institute for Animal Production and productivity information of each breed can be used as basis for policy or model of cultivation and breeding in the community. Research conducted by evaluating the productivity of growth, carcass and the carcass proportion of the three strains of rabbit. Rex and satin growth were no different, and Reza was higher at 12-14 weeks of age. Carcass production comes from cutting the rabbit at the age of six months, this trait is strongly influenced by the weight of rabbits, and Reza gives the lowest performance compared to Rex and Satin. Rex, Satin and Reza were medium type rabbits with dual-purpose product (fur and meat). These rabbits showed the childs growth is good enough, to adapt the environment temperature and high food and have adequate carcass production. Key Words: Rabbit, Rex, Satin, Reza, Growth, Carcass
