本试验旨在研究脱氧雪腐镰刀菌烯醇（ deoxynivalenol，DON）污染饲粮中添加DON吸附剂对断奶仔猪生长性能、血清生化指标及肠道形态的影响。选取120头（36±4）日龄断奶仔猪，随机分为3组（每组4个重复，每个重复10头猪），分别为阴性对照（ NC）组、DON组（阳性对照）、DON＋吸附剂（ DON＋AD）组，试验期28 d。结果表明：1）试验1～14 d，DON组较NC组平均日增重（ADG）下降21．24％（P＜0．05），料重比（F/G）上升15．15％（P＜0．05）；DON＋AD组较DON组ADG提高17．11％（P＜0．05），F/G下降10．53％（P＜0．05）。试验15～28 d及试验全期各组间ADG和平均日采食量均无显著差异（ P＞0．05）。2） DON组较NC组血清总蛋白含量显著下降（ P＜0．05），葡萄糖含量显著上升（ P＜0．05），DON＋AD组较NC组血清葡萄糖、尿素氮含量显著下降（ P＜0．05）。3） DON组较NC组血清肌酸激酶、谷丙转氨酶活性显著提高（ P＜0．05），而加入吸附剂后血清肌酸激酶、谷丙转氨酶、谷草转氨酶活性则恢复到正常水平。4） DON组较NC组空肠绒毛高度和绒毛高度/隐窝深度分别下降21．18％和17．97％（P＜0．05）， DON＋AD组较DON组空肠绒毛高度增加16．49％（ P＜0．05）。因此，DON污染饲粮降低了试验1～14 d断奶仔猪的生长性能，添加DON吸附剂能够改善DON对断奶仔猪生长性能的不利影响，并缓解DON对断奶仔猪所产生的肠道损伤。
本試驗旨在研究脫氧雪腐鐮刀菌烯醇（ deoxynivalenol，DON）汙染飼糧中添加DON吸附劑對斷奶仔豬生長性能、血清生化指標及腸道形態的影響。選取120頭（36±4）日齡斷奶仔豬，隨機分為3組（每組4箇重複，每箇重複10頭豬），分彆為陰性對照（ NC）組、DON組（暘性對照）、DON＋吸附劑（ DON＋AD）組，試驗期28 d。結果錶明：1）試驗1～14 d，DON組較NC組平均日增重（ADG）下降21．24％（P＜0．05），料重比（F/G）上升15．15％（P＜0．05）；DON＋AD組較DON組ADG提高17．11％（P＜0．05），F/G下降10．53％（P＜0．05）。試驗15～28 d及試驗全期各組間ADG和平均日採食量均無顯著差異（ P＞0．05）。2） DON組較NC組血清總蛋白含量顯著下降（ P＜0．05），葡萄糖含量顯著上升（ P＜0．05），DON＋AD組較NC組血清葡萄糖、尿素氮含量顯著下降（ P＜0．05）。3） DON組較NC組血清肌痠激酶、穀丙轉氨酶活性顯著提高（ P＜0．05），而加入吸附劑後血清肌痠激酶、穀丙轉氨酶、穀草轉氨酶活性則恢複到正常水平。4） DON組較NC組空腸絨毛高度和絨毛高度/隱窩深度分彆下降21．18％和17．97％（P＜0．05）， DON＋AD組較DON組空腸絨毛高度增加16．49％（ P＜0．05）。因此，DON汙染飼糧降低瞭試驗1～14 d斷奶仔豬的生長性能，添加DON吸附劑能夠改善DON對斷奶仔豬生長性能的不利影響，併緩解DON對斷奶仔豬所產生的腸道損傷。

This study was conducted to investigate the effects of deoxynivalenol ( DON) adsorbent on growth performance, serum biochemical indexes and intestinal morphology of weaner piglets fed DON-contaminated diets.One hundred and twenty weaner piglets at (36±4) days of age were randomly allocated to 3 groups (4 replicates per group and 10 piglets per replicate): negative control ( NC) group, DON group ( positive con-trol) and DON+adsorbent ( DON+AD) group.The trial lasted for 28 days.Results showed as follows:1) on 1 to 14 days of experiment, compared with NC group, average daily gain ( ADG) in DON group was reduced by 21.24%( P<0.05) and feed/gain ( F/G) was increased by 15.15%( P<0.05) .ADG in DON+AD group was higher by 17.11%than that in DON group ( P<0.05) and F/G was lower by 10.53%than that in DON group ( P<0.05) .On 15 to 28 days of experiment and during the whole trial period, ADG and average daily feed intake were no significant differences among all groups ( P>0.05) .2) Compared with NC group, the ser-um total protein content in DON group was significantly decreased ( P<0.05) and glucose content was signifi-cantly increased ( P<0.05) .In DON+AD group, serum glucose and urea nitrogen contents were significantly decreased compared with NC group ( P<0.05) .3) Compared with NC group, the serum activities of creatine kinase (CK) and glutamic-pyruvic transaminase (GPT) were significantly increased (P<0.05), while after adding the adsorbent, the serum activities of CK, GPT and glutamic-oxal( o) acetic transaminase ( GOT) were returned to normal level.4) Compared with NC group, the villous height and villous height/crypt depth of je-junum in DON group were decreased by 21.18%and 17.97%( P<0.05) , respectively, and DON+AD group had a 16.49%higher jejunum villous height than DON group (P<0.05).It is concluded that the growth per-formance of piglets fed DON-contaminated diets on 1 to 14 days of experiment is reduced, while DON adsor-bent may improve the growth performance of weaner piglets and can alleviate intestine damage induced by DON.
