Abstract: For effectively utilizing ginseng processing by-products resources and clarifying the effects of which on chicken carcass qualities and metabolism,864 healthy newborn Jilin Luhua chicken,male and weighted at (40.88±2.43) g were chosen and randomly divided into 9 treatments,8 repetitions in each treatment and 12 chicken in each repetition.These treatments were control,ginseng stem and leaf (GSL) treatments (0.6%,1.2%,1.8% and 2.4%) and ginseng residual parts (rhizome and root hair,GRP) treatments (0.2%,0.4%,0.6% and 0.8%).The experiment lasted 150 d and the effects of ginseng processing by-products on slaughter performance,carcass quality and blood biochemistry indices were comprehensively evaluated.The results showed that:①There was no significant difference in slaughter performance among all the treatments.②Water content of leg muscle in 1.8% GSL group was significantly higher than control and 0.6% GSL groups (P<0.05),fat contents of leg muscle in 0.6% and 1.8% GSL groups were significantly lower than control group (P < 0.05);Water content of chest muscle in 0.8% GRP group was significantly higher than 0.4% GRP group (P < 0.05),and 0.4% and 0.8% GRP increased protein contents of chest muscle compared with control and 0.6% GRP groups (P < 0.05);Fat contents of chest and leg muscle in 0.4% GRP group were higher than 0.8% GRP group (P < 0.05).③In 2.4% GSL treatment,the plasma LDL-C level was significantly higher than 0.6% GSL group(P < 0.05),creatinine (CRE) was significantly higher than other GSL treatments (P < 0.05),and blood urea nitrogen (BUN) was higher than 1.2% and 1.8% GSL treatments (P < 0.05).In 0.8% GRP group,plasma total protein (TP) was significantly higher than control and 0.6% GRP groups (P<0.05),and globulin (GLB) level was also higher than 0.6% GRP group (P < 0.05).Synthesizing the above results,the suitable additive ranges of GSL and GRP in Jilin Luhua chicken feed were 0.6% to 1.8% and 0.4% to 0.8%,respectively.
