Abstract：The experiment aimed to investigate the effects of liensinine and its compound on the growth performance of broilers.A total of 140 Cobb broilers at 7 days of age were randomly divided into seven groups,with four replicates per group and five broilers per replicate.The control group(MOCK group)was fed a basal diet,while the experimental groups received additional supplements in the basal diet:400 mg/kg guanidinoacetic acid(GAA group),40 mg/kg liensinine(LIE group),40 mg/kg liensinine+200 mg/kg hawthorn(LIE-1 group),20 mg/kg liensinine+100 mg/kg hawthorn(LIE-2 group),33 mg/kg guanidinoacetic acid+100 mg/kg hawthorn(GAA-1 group),and 33 mg/kg betaine+100 mg/kg hawthorn(BET group).The pre-test lasted for seven days and the experiment lasted for 14 days.The results showed that compared to the MOCK group,the average daily weight gain,dressing percentage,and eviscerated yield of broilers in the LIE,LIE-1,and LIE-2 groups were extremely increased(P＜0.01),and the feed conversion ratio was extremely decreased(P＜0.01).The thigh muscle percentage in the LIE and LIE-1 groups was significantly increased(P＜0.05).Compared to the MOCK group,the serum albumin(ALB)content in the LIE,LIE-1,and LIE-2 groups was extremely increased(P＜0.01),and the serum glucose(GLU)content in the LIE and LIE-1 groups was extremely increased(P＜0.01),while the triglyceride(TG)content was extremely decreased(P＜0.01).The high-density lipoprotein cholesterol(HDL-C)content in the LIE group was significantly increased(P＜0.05),and the total protein(TP)content was extremely increased(P＜0.01),the serum HDL-C content in the LIE-1 group was extremely increased(P＜0.01).Compared to the MOCK group,the space between the muscle fibers of the leg muscles of the LIE and LIE-1 groups was compact,and the muscle fibers were arranged in an orderly manner and relatively full.The study indicates that adding 40 mg/kg liensinine or 40 mg/kg liensinine+200 mg/kg hawthorn to the feed can effectively improve the growth performance and slaughter performance of broilers.
