Abstract
The aim of the present study was to analyse the influence of year, season and parity on productive
and reproductive performances in 110 Soviet Chinchilla and 64 White Giant rabbits under tropical climatic
conditions of Tamil Nadu in the period between 2005 and 2009. A total of 731 records for the overall leastsquares
means for litter size at birth and weaning, litter weight at birth and weaning, average weight of
kit at birth and weaning and pre-weaning growth rate in Soviet Chinchilla rabbits were 5.1±0.1, 3.7±0.1,
256.4±6.9 g, 2465.4±73.6 g, 50.4±0.7 g, 694.1±13.1 g and 15.3±0.3 g/d, respectively, and the values for
White Giant rabbits were 5.1±0.1, 4.1±0.1, 259.6±6.1 g, 2432.6±68.7 g, 50.8±0.4 g, 614.6±13.5 g and
13.4±0.3 g/d, respectively. Breed had significant effect on litter size at weaning (P<0.01), average weight of kit
at weaning (P<0.05) and pre-weaning growth rate (P<0.01). Year of birth had significant effect on litter size and
litter weight at birth (P<0.05), litter size and litter weight at weaning (P<0.01), average weight of kits at weaning
and pre-weaning growth rate (P<0.01) in Soviet Chinchilla and White Giant rabbits. Season of birth had
significant effect on litter weight at birth and weaning (P<0.05), average weight of kits at birth (P<0.05) and
weaning (P<0.01) and pre-weaning growth rate (P<0.01) in both the breeds. Parity had significant effect on
litter weight and average weight of kits at weaning (P<0.01) and pre-weaning growth rate (P<0.01). The study
revealed that the Soviet Chinchilla and White Giant breeds performed well in the tropical climatic conditions
of Tamil Nadu and could be used for profitable meat production. The significant influence of factors such as
year of birth and season of birth observed on different production traits emphasises the role played by the
management in optimising the realisation of genetic potential under local agro-climatic conditions.
