Evaluation of Qualitative Indices of Meat Production in Rabbits
Keywords:meat carcass weight, rabbits, slaughter yield, weight carcass weight
Meat, in most cases, is a basic production in rabbits. The influence on meat quality and quantity have such factors as breed, age, slaughter gain, sex, etc. By age, adult rabbits have a higher body weight compared with the young, but their meat is more expensive. The most convenient is intensive growth of youth as the age of 3 months to be 2.3 to 2.5 kg body weight, food and labor costs during this period was minimal. It is considered optimal as young rabbits are slaughtered when they reach 50-60% by weight of adult animals. The biological material which was used was represented in two groups of Chinchilla rabbit and Flanders breed, each one consisting of seven rabbits of various sex. Groups of rabbits had the same conditions of maintenance and nutrition. Carcass weight was determined at slaughter, carcass meat, bones, by-products, blood, head, skin of young rabbit. The largest share of the carcass of live weight was obtained at age 4 months - 59%, and meat in the carcass weight at 2 months of life - 71.2% at Chinchilla breed. On average 31.9% had bones, by-products - 6.23%, blood - 3.78% head - 8.21% and skin of young rabbit - 11.9%. Average of carcass weight from live weight was 52.76%, in Flanders breed the highest recorded at age 4 months and 66.78% of the carcass meat, the highest being at 2 months old. The average weight of bones was 33.21%, by-products - 6.25%, blood - 3.53%, the head - 7.86%, and the skin of young rabbit - 11.89%. Slaughter gain ranged from 47% to 59% at Chinchilla breed, and from 47% to 60% in Flanders breed. The highest index was recorded in both breeds at the age of four months.
