The effects of dandelion polysaccharides on growth performance,serum biochemical indicators,and immune indicators in heat stressed piglets
To explore the effects of dandelion polysaccharides on the growth performance,serum biochemical indicators,and immune indicators of heat stressed piglets.500 healthy and 28 day old DLY ternary hybrid piglets with similar weight(8.34±0.27 kg)were randomly divided into 5 groups,with 10 replicates in each group.The control group and heat stress group were fed with basic feed,while treatment I,II,and III were fed with experimental feed supplemented with 400,800,and 1600 mg/kg TMP in the basic feed,respectively.The experimental data showed that compared with the heat stress group,the final weight of piglets in treatment group III significantly increased by 11.37%(P＜0.05),the average daily weight gain significantly increased by 24.63%(P＜0.05),the average daily feed intake significantly increased by 7.59%(P＜0.05),the feed to meat ratio significantly decreased by 13.67%(P＜0.05),and the diarrhea rate significantly decreased by 51.85%(P＜0.05).Compared with the heat stress group,the serum TP,ALB content,T-AOC ability,and SOD activity of piglets in treatment group III were significantly increased(P＜0.05),while the BUN and MDA content were significantly reduced(P＜0.05).Compared with the heat stress group,the serum IgA and IgG contents of piglets in treatment group III were significantly increased(P＜0.05),while the levels of IL-6 and TNF-α were significantly reduced(P＜0.05).The serum LZM content of piglets in treatment groups I～III was significantly increased(P＜0.05).Supplementing with TMP(1600 mg/kg)can partially alleviate the negative regulation of heat stress on piglet growth,development,and serum indicators.
