摘要
[目的]旨在探究巴戟天多糖(Morinda officinalis How polysaccharides,MOP)对福美双诱导的胫骨软骨发育不良(tibial dyschondroplasia,TD)肉鸡生产性能、胫骨指数、胫骨钙磷灰分和血清电解质的影响。[方法]选取1日龄健康AA肉仔鸡120只,随机分为3组,每组4个重复,每个重复10只肉鸡。对照组(CON组)饲喂基础日粮;福美双诱导TD组(TD组)饲喂基础饲料,在第4天到第7天的饲料中添加100 mg/kg的福美双进行TD模型建立;巴戟天多糖组(MOP组)在接受TD造模处理后,在第7天到第15天的饲料中添加400 mg/kg的巴戟天多糖。[结果]与CON组相比,从试验开始到试验第7天,TD组肉鸡的平均采食量和平均日增重显著(P<0.05)降低,料肉比增加(P>0.05);在试验第7天、第11天和第15天时,TD组肉鸡的胫骨生长板宽度和生长板宽度系数显著(P<0.05)增加,胫骨重量和胫骨长度显著(P<0.05)降低,胫骨重量指数降低(P>0.05),胫骨灰分含量显著(P<0.05)降低,并且血清中电解质紊乱;与TD组相比,在试验第11天和第15天时,MOP组肉鸡的料肉比有降低的趋势(P>0.05),MOP组肉鸡的生长板宽度和生长板宽度系数显著降低(P<0.05),胫骨重量、胫骨长度和胫骨重量指数均显著(P<0.05)提高;在试验第11天时,MOP组肉鸡的胫骨灰分含量显著(P<0.05)提高;随着试验时间的延长,MOP组肉鸡的血清电解质含量趋于平衡。[结论]饲料中添加巴戟天多糖可以有效缓解和改善由福美双诱导的肉鸡TD症状。
[Objective]To investigate the effects of dietary supplementation of Morinda officinalis How polysaccharides(MOP)on production performance,tibia index,tibial content of calcium,phosphorus and ash,and serum electrolytes level in broilers with tibial dyschondroplasia(TD)induced by thiram.[Method]A total of 1201-day-old healthy AA broilers were randomly divided into 3 groups with 4 replicates in each group and 10 broilers in each replicate.The broilers served as control(CON group)were fed with basal diet;the broilers used to establish TD model induced by thiram(TD group)were fed with basal diet at the initial period of the experiment,and then received dietary supplementation of 100 mg/kg thiram from the 4th to 7th day of the experiment;after receiving the same treatment with TD group,the broilers in MOP group were fed with basal diet supplemented with 400 mg/kg MOP from the 7th to 15th day of the experiment.[Result]Compared with the CON group,during the first 7 days of the experiment,the average feed intake and average daily gain of TD group was decreased significantly(P<0.05),and the feed to gain ratio was increased(P>0.05);in TD group,the tibial growth plate width and coefficient of growth plate width was increased significantly(P<0.05),the tibial weight,length and ash content were decreased significantly(P<0.05),and the tibial weight index was reduced(P>0.05)on the 7th,11th and 15th day of the experiment,in addition,the appearance of serum electrolyte disorder was also observed;compared with TD group,the MOP group had decreased feed to gain ratio(P>0.05),significantly(P<0.05)decreased tibial growth plate width and coefficient of growth plate width,and significantly(P<0.05)increased tibial weight,length and weight index on the 11th and 15th day of the experiment;the tibial ash content of MOP group was increased significantly(P<0.05)on the 11th day of the experiment;with the extension of the experimental period,the serum electrolytes level of the MOP group tended to balance.[Conclusion]Dietary supplementation of MOP
