Effects of Attapulgite Nano Zinc Oxide on Growth Performance, Organ Indices and Blood Biochemical Indices of Weaned Piglets
摘要
Abstract
The experiment was conducted to explore the effects of attapulgite nano zinc oxide on the growth performance, organ indices and blood biochemical indices of weaned piglets. A total of 210 Duroc×Landrace× Yorkshire piglets with 21?day?old and similar body weight of(6.30±0.51)kg were randomly allocated into 7 groups with 6 replicates each and 5 pigs in each replicate. Pigs in the control group(CON group)were fed a basal diet,in antibiotic group(ANT group)were fed a basal diet supplemented with 100 mg/kg 50% olaquin?dox,150 mg/kg 15% chlortetracycline and 50 mg/kg 10% sulfate colistin, and in the other groups were fed the basal diet supplemented with 3 000 mg/kg zinc oxide(ZO group), 800 mg/kg nano?zinc oxide(NZO group), and 700, 1 000 and 1 300 mg/kg attapulgite nano zinc oxide(LA?ZO group, MA?ZO group and HA?ZO group), respectively. The experiment lasted for 9 days after 3 days adaption. The results showed as follows:1)compared with CON group, dietary attapulgite nano zinc oxide significantly increased the average daily feed intake and average daily gain of weaned piglets(P<0.05).2)Compared with CON group and ANT group, the diarrhea rate in LA?ZO group was significantly decreased(P<0.05). The diarrhea index in LA?ZO group was significantly lower than that in CON group,ANT group and NZO group(P<0.05).3)The pancre?as index in LA?ZO group and MA?ZO group was significantly higher than that in NZO group(P<0.05). 4) Compared with CON group, the contents of blood total cholesterol(TC)and triglyceride(TG)in MA?ZO group was significantly decreased(P<0.05), and the blood high density lipoprotein content in MA?ZO group was significantly increased(P<0.05),which was significantly higher than that in ANT group and NZO group (P<0.05). The blood high density lipoprotein content in HA?ZO group was significantly higher than that in CON group and ANT group(P<0.05). The results indicate that dietary attapulgite nano?zinc oxide can im?prove the growth performance,decrease the diarrhea rate,and promote the growth and development of weaned piglets, meanwhile decrease the contents of TG and TC in blood, increase blood high density lipoprotein con?tent, strengthen lipid metabolism and pancreas development. Thus, it has potential to replace the utilization of antibiotics and high zinc for weaned piglets.关键词
