Abstract
The slaughter performance and body size indicators of 30 China Micro-ducks with 94 days age were determined,Which were fed under free range mode.The results of correlation analysis showed that the correlation coefficient of live weight with body slope length,keel bone length,chest width,shank girth,half-diving depth were respectively 0.588,0.660,0.618,0.654,0.582,which appeared very significant level(P0.01).The correlation coefficient of eviscerated weight with body slope length,keel bone length,shank girth,half-diving depth were respectively 0.476,0.566,0.552,0.455,which appeared significant(P0.05) or very significant level(P0.01).In addition,the models of live weight with body slope length,keel bone length,chest width,shank girth,half-diving depth and eviscerated weight with body slope length,keel bone length,shank girth,half-diving depth were build respectively,two models were appeared significant level(P0.05) after F test.
