In order to promote the resource utilization of invasive plant Bidens alba(L.)DC in animal husbandry,the formulation composed of 4.00 kg Bidens alba(L.)DC,1.20 kg Plantago,0.10 kg ginger and 0.25 kg garlic were extracted with water,then precipitated with ethanol,and the final extract product of 0.15 kg was obtained after a series of processing.The extracts were added to the feed at the ratio of 0 mg/kg(control group),125 mg/kg(low group),250 mg/kg(medium group),500 mg/kg(high group)to feed DurocX Landrace× Yorkshire growing pigs.After 20 days,compared with the control group,the feed to gain ratio of high and medium groups decrease d by 4.52％and 2.08％respectively.After 10 days of feed-ing,cholesterol concentration and alkaline phosphatase activity of high group were significantly higher than those of medium group(P＜0.01);glutamyl transferase activity of low group was significantly higher than that of medium group(P＜0.05);serum phosphorus of high group was significantly higher than that of low group(P＜0.05).After 20 days of feeding,Alkaline phosphatase activity and globulin of high,medi-um and low groups were significantly higher than that of control group(P＜0.01),so was creatinine of high and medium groups(P＜0.05).Cholesterol concentration and glutamyltransferase activity of high group were significantly higher than those of control group(P＜0.05);albumin concentration and alanine aminotransferase activity of high group were significantly lower than those of control group(P＜0.05).In conclusion,Bidens alba(L.)DC formulation extracts have no hepatotoxicity,nephrotoxicity and pancreat-ic toxicity to growing pigs,and it can promote the metabolism of fat,energy and protein,and facilitate the absorption of calcium,phosphorus,so as to improve the growth performance of growing pigs.
