CARCASS CHARACTERISTICS OF BROILER RABBIT FED ON SWEET POTATO BASED RATION
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 1
Abstract
The present investigation was carried out to study the carcass characteristics and growth performance of two breeds of rabbits New Zealand White (NZW) and Soviet Chinchilla (SC) raised on rations containing various levels of sweet potato (Ipomoea batatas) as an energy source. Five groups of weaned NZW and five groups of weaned SC rabbits, six in each group were fed five isonitrogenous concentrate mixtures containing 0,10,20,30 and 40 percent boiled sweet potato replacing equivalent amount of maize grain for a period of 45 days. Sweet potato feeding influenced the carcass characteristics and body composition of experimental rabbit. The live weight before and after fasting was significantly (P<0.01) higher in Ration 2, 3 and 4 group, but there was no significant difference in shrinkage percentage due to incorporation of sweet potato in the diets. The percent yield of various edible offal, dressing percentage, percent yield of various wholesale cuts, significantly differed, however weight of total inedible offal were not significantly (P<0.05) influenced by dietary variations. Except the percentage of moisture, that of crude protein, crude fat and ash values were not influenced by the inclusion of sweet potato tuber in rations, however there were breed differences in all the above traits. The incorporation of sweet potato in rations significantly (P<0.01) affected the final body weight of both breed of rabbits.
