Effects of Antrodia cinnamomea polysaccharide and zinc on slaughter per-formance,meat quality and muscle antioxidant capacity of Mahuang broilers
The purpose of this study was to explore the effects of the addition of Antrodia cinnamomea polysaccharides and zinc in the diet on growth performance,slaughter performance,meat quality and antioxidant capacity of Mahuang broilers,and to provide theoretical and experi-mental basis for the application of Antrodia cinnamomea polysaccharides and zinc in broilers production.A total of 180 35-day-old healthy Mahuang broilers were randomly di-vided into three groups:basal diet group(CK),the basal diet supplemented with 500 mg/kg Antrodia cinnamomea polysaccharides(ACP)group and the basal diet supplemented with 500 mg/kg Antrodia cinnamomea polysaccharides and 100 mg/kg zinc(ACP+Zn)group,with six replicates per group and 10 broilers per replicate.The experiment lasted for 28 days,and growth performance related indexes were recorded during the ex-periment.At 63 days of age,one to two chickens from each replicate group were slaughtered and sampled to determine indexes related to slaughter performance,meat quality and antioxidant activity.The results showed that compared with the control,pH45 min values of breast muscle in ACP and ACP+Zn treatments were significantly increased(P<0.05),and drip loss rate was significantly decreased(P<0.05).Compared with control and ACP+Zn treatment,the chewiness of breast muscle in ACP treatment was significantly increased(P<0.05).Compared with the control,malondialdehyde(MDA)content in breast muscle in ACP and ACP+Zn treatments was significantly decreased(P<0.05).The results indicated that dietary supplemen-tation of Antrodia cinnamomea polysaccharides alone or combined supplementation of Antrodia cinnamomea polysaccharides and zinc could reduce the drip loss of breast muscle,regulate its pH,improve muscle quality and antioxidant capacity of broilers breast muscle.
