ABSTRACT

The pre-weaning body weights at birth, 1, 2, 3 and 4 weeks, Average Daily Gain (ADG) during
1st, 2nd, 3rd and 4th week of age and Cumulative ADG (CADG) up to 2, 3 and 4 weeks of age of 171
Soviet Chinchilla bunnies were analyzed. Season of birth significantly affected the body weights at
birth and 1-week age, year of birth had significant effect on body weight at one-week age,
whereas the litter size at birth significantly influenced the body weight at birth and 4 weeks age,
ADG during 4th week and CADG up to 4 weeks age. The overall least squares means of body
weights at birth, 1, 2, 3 and 4 weeks of age were 57.98, 104.53, 161.68, 225.87 and 322.45 g,
respectively, while the means for ADG during 1st, 2nd, 3rd and 4th week and CADG up to 2, 3 and 4 weeks of age were 6.70, 8.09, 9.17, 13.80, 7.40, 7.99 and 9.44 g, respectively. The estimates of
heritability for pre-weaning body weights and growth rates ranged from low (0.07 0.19) to high
(0.65 ± 0.31). The genetic correlations ranged from medium (-0.39) to high (0.86), while the
phenotypic correlations varied from low (-0.17) to medium (0.49).
