摘要
本试验旨在研究富虾青素玉米对白羽肉鸡生长性能、屠宰性能、血液指标和组织虾青素含量的影响,以评价富虾青素玉米作为肉鸡饲料原料的安全性。试验选取432只健康的1日龄雄性白羽肉鸡,随机分为2个组,每组12个重复,每个重复18只鸡。对照组饲喂含非转基因亲本玉米的玉米-豆粕型基础饲粮,试验组饲喂含富虾青素玉米的玉米-豆粕型基础饲粮。试验期42 d。结果表明:1)2组之间平均日采食量、平均日增重和料重比均没有显著差异(P>0.05)。2)2组之间屠宰性能及器官指数均没有显著差异(P>0.05)。3)与对照组相比,试验组的血液红细胞平均体积有降低趋势(P=0.093),其他血常规指标均没有显著差异(P>0.05)。4)2组之间血清生化指标均没有显著差异(P>0.05)。5)与对照组相比,试验组的血清超氧化物歧化酶活性(P=0.073)和总抗氧化能力(P=0.052)有升高趋势,血清丙二醛含量有降低趋势(P=0.084)。6)虾青素可以在血清及心脏、肝脏和胸肌组织富集,试验组血清中虾青素含量为10.29μg/mL,心脏、肝脏和胸肌组织中虾青素含量分别为0.07、0.17和0.05μg/g。综上所述,富虾青素玉米不会影响白羽肉鸡的生长和健康,可以作为肉鸡的饲料原料。
The purpose of this study was to study the effects of astaxanthin-rich maize on growth performance,slaughter performance,blood indexes and tissue astaxanthin contents of white-feathered broilers,and to evaluate the safety of astaxanthin-rich corn as a feed raw material for broilers.A total of 432 one-day-old male white-feathered broilers were randomly divided into 2 groups with 12 replicates in each group and 18 chickens in each replicate.Broilers in the control group was fed a corn-soybean meal basal diet containing non-genetically modified parental maize,and others in the test group was fed a corn-soybean meal basal diet containing astaxanthin-rich maize.The experimental period was 42 days.The results showed as follows:1)there were no significant differences in average daily feed intake,average daily gain and feed to gain ratio between 2 groups(P>0.05).2)There were no significant differences in slaughter performance and organ indexes between 2 groups(P>0.05).3)Compared with the control group,the blood mean corpuscular volume of the test group tended to decrease(P=0.093),and other blood routine indexes were no significant differences(P>0.05).4)There were no significant differences in serum biochemical indexes between 2 groups(P>0.05).5)Compared with the control group,the serum superoxide dismutase activity(P=0.073)and total antioxidant capacity(P=0.052)of the test group tended to increase,and the serum malondialdehyde content tended to decrease(P=0.084).6)After feeding astaxanthin-rich corn,astaxanthin can be enriched in serum and heart,liver and pectoral muscle tissues,the serum astaxanthin content in the test group was 10.29μg/mL,and the contents of astaxanthin in heart,liver and pectoral muscle tissues were 0.07,0.17 and 0.05μg/g,respectively.In summary,the astaxanthin-rich maize will not affect the growth and health of white-feathered broilers,and it can be used as a raw material for broilers.
