饲料中添加枸杞多糖对断奶仔猪生长性能和血清生化指标的影响

Effects of wolfberry polysaccharide supplemented to diets on the growth performance and serum biochemical indices of weanling piglets

文章旨在研究饲料中添加枸杞多糖对断奶仔猪生长性能和血清生化指标的影响。本研究将40只健康仔猪随机分为空白对照组、枸杞多糖高、中、低剂量组,每组10只,共计4组,空白对照组饲喂不添加药物的饲料;枸杞多糖高、中、低剂量组分别添加400 mg/kg、200 mg/kg及100 mg/kg枸杞多糖,连续添加7 d。结果表明,饲料中添加枸杞多糖对断奶仔猪的临床表现无不良影响,枸杞多糖高剂量可明显降低断奶仔猪的腹泻率。枸杞多糖高剂量组日均增重增加明显,与空白对照组相比差异极显著(P<0.01),与对照组相比,枸杞多糖高剂量组料重比显著降低(P>0.05),球蛋白显著增高(P<0.05)。且枸杞多糖组对血清白蛋白、总蛋白、尿素等生化指标无不良影响。

To investigate the effects of adding wolfberry polysaccharide on the growth performance and serum biochemical parameters of weaned piglets.Forty healthy piglets were randomLy divided into a blank control group,a high,medium and low dose group of sputum polysaccharides,10 rats in each group,a total of 4 groups,and the blank control group was fed with no drug-added feed.The high,medium and low dose groups of wolfberry polysaccharide were added at 400 mg,200 mg and 100 mg per kg of feed,respectively,for 7 days.The results showed that the addition of wolfberry polysaccharide in the feed had no adverse effect on the clinical manifestations of weaned piglets.The high dose of wolfberry polysaccharide could significantly reduce the diarrhea rate of weaned piglets.The daily weight gain of the high-dose wolfberry polysaccharide group increased significantly,compared with the blank control group,the difference was extremely significant(P<0.01),and the weight-to-weight ratio of the high-dose wolfberry polysaccharide group decreased,compared with the blank control group,the difference was significant(P>0.05),the high-dose group globulin content of sputum wolfberry polysaccharide increased,compared with the blank control group,the difference was significant(P<0.05).The wolfberry polysaccharide group had no adverse effects on serum albumin,total protein,urea and other biochemical indicators.
