摘要
为了解香菇多糖和七清败毒颗粒联合应用对集团化猪场猪繁殖与呼吸障碍综合征(PRRS)的防控效果,本研究选取3~4胎次、体重为(268.00±33.59)kg的母猪100头,随机分为2组(每组5个重复,每个重复10头猪),分别为对照组和试验组。对照组饲喂基础饲粮,试验组在基础饲粮中添加2.5 g/(头·d)香菇多糖+5.0 g/(头·d)七清败毒颗粒。试验对母猪繁殖性能、血清生化指标、PRRSV抗体水平、仔猪脐带血中PRRSV载量进行检测。试验期90 d。结果表明:在母猪繁殖性能方面,与对照组相比,试验组窝均产仔数、平均日增重极显著提高(P<0.01),窝均死胎数极显著降低(P<0.01)。在血清生化指标方面,第30天,试验组血清谷草转氨酶(AST)活性显著低于对照组(P<0.05);第90天,试验组血清谷丙转氨酶(ALT)、AST活性及总胆红素(TBIL)含量显著低于对照组(P<0.05),血清尿素(UN)含量极显著降低于对照组(P<0.01)。在PRRSV抗体检测方面,第30天,试验组S/P值极显著低于对照组(P<0.01);第90天,试验组显著低于对照组(P<0.05),离散度有降低趋势,符合正态分布。在仔猪脐带血PRRSV抗原检测方面,对照组抗原阳性率为10%,试验组为0。综上所述,感染PRRS的集团化猪场应用香菇多糖和七清败毒颗粒可以有效地提升母猪繁殖性能、影响部分血清生化指标水平、维持猪群PRRSV抗体S/P值稳定、降低仔猪PRRSV阳性率,起到很好地防控PRRS的效果。
This study aimed to investigate the preventive and control effects of lentinan and Qiqing Baidu granules on porcine reproductive and respiratory syndrome(PRRS)in large-scale pig farms.A total of 100 sows with 3 to 4 parity and weight of(268.00±33.59)kg were randomly divided into two groups(5 replicates in each group and 10 sows in each replicate),which were respectively control group and experimental group.Pigs in the control group were fed a basal diet,and those in the experimental group were fed the basal diet supplemented with 2.5 g/(head·d)lentinan+5.0 g/(head·d)Qiqing Baidu granules.Over a 90-day trial period,the sows’reproduction performance,serum biochemical indexes,levels of PRRSV antibodies,and PRRSV load in piglets’umbilical cord blood were measured.The results showed that in terms of sow reproductive performance,the experimental group had significantly higher average litter size,and average daily gain(P<0.01),and a markedly lower average litter number of dead piglets(P<0.01)compared with the control group.In terms of serum biochemical indexes,on day 30,the experimental group’s glutamic oxalic aminotransferase(AST)activity was significantly lower than that in the control group(P<0.05),and on day 90,serum alanine aminotransferase(ALT)and AST activities and total bilirubin(TBIL)content were also significantly lower(P<0.05),with serum urea(UN)content markedly reduced compared with control group(P<0.01).In terms of PRRSV antibody testing,the mean S/P value in the experimental group was significantly lower than that in the control group on day 30(P<0.01),and significantly lower than that in the control group on day 90(P<0.05),and a decreasing trend in the dispersion in the experimental group,which conformed to a normal distribution.The PRRSV antigen detection in piglets’umbilical cord blood showed a 10%positive rate in the control group,while the experimental group had a 0 positive rate.In conclusion,the use of lentinan and Qiqing Baidu granules can effectively improve sows’reproduction performa
