The results indicate that the slaughter weight significantly influences the weight of the fore legs (P< 0.05) and hind legs (P< 0.01). The quadratic regression equations provide the best estimators for all the carcass cuts and the carcass as a whole. The accuracy of the predictors is highest for Key words: Soviet Chinchilla bucks %Regression equations %Carcass cuts %Eastern India INTRODUCTION time frame, however keeping into account allometric Rabbit are reared both for pelt, meat and as laboratory the growth of different species and may be even breeds animals. It is estimated that the total population of rabbits and types are different at different phases of life and reared under farm conditions in India is estimated to be hence can be best fitted using different growth/ non linear around 0.47987 million, the numbers of rabbits other than models. The present study therefore was carried out to the wool type Angora breed is estimated at 123 thousand predict the weight of the different commercially important buck and 143 thousand does, with a population of 102 and carcass cuts of the rabbits using non invasive techniques. 113 thousand bucks in the does respectively in the rural area and the remaining in the urban area respectively [1]. MATERIALS AND METHODS Rabbit rearing in West Bengal is being promoted by the authorities of the government as a mean to create The data under consideration pertains to 30 Soviet employment opportunities for the less advantaged section Chinchilla bucks that were reared at a commercial farm of the society and also to create rural employment situated in the state of West Bengal, India. The region opportunities. However, it has since been noticed that where the study was conducted is situated near to the many of the people who started rearing the rabbits in a tropic of cancer and is characterized by hot (20-37°C) and commercial scale are closing down the profession. This is humid (65-97%) climate the year round ( except for the two grossly attributed to lack of adequate marketing channel months of the year December and January when the for the meat and also because the cost of feeding the climate is cold and humidity is also less) . The rabbits rabbits is significantly higher than that of the small were reared in individual cages (after weaning 30 days of ruminants (because a significant part of the diet comprises age) till they were slaughtered at 85 days of age. The of concentrate feed which is getting costlier day by day). rabbits were reared on self formulated ration comprising Another factor that is leading to the disinterest is the of maize (75%), soybean cake (5%), sunflower cake (10%), entrepreneurs are the traditional culinary habit of the meat sesame cake (7%) and appropriate amount of minerals and consumers where there is no place for the rabbit meat. vitamins (3%), besides green grass ( fodder sorghum Therefore, one of the ways save the potentially important (Sorgum bicolor ), para grass (Brachiaria mutica), doob industry is to go in for meat processing where important grass (Cynodon dactylon) were given adlib, depending carcass cuts can be processed and sold to the customers upon the season and availability. Prior to slaughter the form the high niche of the society. The usual process of rabbits were fasted for 8-12 hours when they received growth has been many times measured on a longitudinal only water. Individual animal was weighed on a digital growth of the different organs it has been observed that
