钝顶螺旋藻粉对断奶仔猪生长性能、血清生化指标及免疫功能的影响
Effects of Arthrospira platensis powder on growth performance,serum biochemical parameters,and immune function in weaned piglets
摘要
Abstract
This experiment aimed to investigate the effects of dietary supplementation with Arthrospira platensis powder(APP)on the growth performance,serum biochemical parameters,and immune function in weaned piglets.A total of 40 healthy weaned piglets at 40 days of age with similar body weight were randomly divided into four groups,with 10 replicates per group and one piglet per replicate.The control group(group CON)was fed a basal diet,while the experimental groups were supplemented with 2.0(group APP2),4.0(group APP4),and 8.0 g/kg(group APP8)of APP in the basal diet,respectively.The pre-test period was seven days,and the formal test period was 30 days.The results showed that compared with group CON,the average daily gain,average daily feed intake,and feed-to-gain ratio of the experimental groups showed no significant differences(P>0.05).The mean corpuscular volume(MCV),mean corpuscular hemoglobin(MCH),and mean corpuscular hemoglobin concentration(MCHC)in group APP8 were significantly decreased(P<0.05).The mean platelet volume(MPV)in the experimental groups was significantly decreased(P<0.05).The activity of serum alanine aminotransferase(ALT)and the concentrations of urea nitrogen(BUN)and creatinine(CREA)in group APP2 were significantly increased(P<0.05).The content of serum glucose(GLU)in experimental groups was significantly decreased(P<0.05).The content of serum interleukin-2(IL-2)in experimental groups was significantly increased(P<0.05),while interleukin-4(IL-4)content was significantly decreased(P<0.05).The content of serum interleukin-6(IL-6)in groups APP4 and APP8 was significantly decreased(P<0.05),and interferon-γ(IFN-γ)content was significantly increased(P<0.05).The content of serum IFN-γ in group APP2 was significantly decreased(P<0.05).The study shows that APP had no significant effect on the growth performance of weaned piglets but improved immune function to a certain extent.Based on the comprehensive results,a recommended supplementation dose is 8.0 g/kg of APP.关键词
