摘　　要：随机选取 １０ 头健康的４２～４５ 天断奶长白仔猪，分别于断奶时、断奶后７ 天、１４ 天上午采血，检验血液学、血清生化等多项指标，结果如下：仔猪血清 Ａ Ｓ Ｔ、 Ｃ Ｋ、 Ｌ Ｄ Ｈ 活性在断奶后 ７ 天时都升高，其中 Ａ Ｓ Ｔ、 Ｌ Ｄ Ｈ活性与断奶时相比差异极显著（ Ｐ＜ ００１）；血清 Ａ Ｍ Ｙ Ｌ 活性，断奶后均比断奶时高，但无统计学上差异（ Ｐ＞００５）；血清 Ｔ Ｐ、 Ｇ Ｌ Ｏ Ｂ、 Ａ Ｌ Ｂ、 Ｂ Ｕ Ｎ、 Ｃ Ｈ Ｏ Ｌ 含量在断奶后极显著或显著降低（ Ｐ＜ ００１ 或 Ｐ＜ ００５）； Ｇ Ｌ Ｕ、 Ｃ Ｒ Ｅ Ａ、 Ｔ Ｃ Ｏ２ 含量降低，但无统计学上差异（ Ｐ＞ ００５）。血液 Ｒ Ｂ Ｃ、 Ｈ Ｇ Ｂ、 Ｈ Ｃ Ｔ、 Ｍ Ｃ Ｖ 断奶后极显著降低（ Ｐ＜００１）， Ｍ Ｃ Ｈ Ｃ 断奶后极显著升高（ Ｐ＜ ００１）； Ｗ Ｂ Ｃ、 Ｐ Ｌ Ｔ 等断奶后虽有变化，但均无统计学上差异（ Ｐ＞００５）。结果表明，仔猪在断奶后一段时间，处于营养缺乏性单纯小红细胞性贫血状态。piglets weaned at 42～45 d were selected.Blood samples were collected at weaning,7d,14d after weaning and analyzed for hematological and biochemical profiles.The results showed as follows:Serum activities of AST,LDH significantly increased(P<0.01)at 7d after weaning.No significant difference(P> 0.05 )was observed though activity of CK increased.Serum activity of AMYL gradually increased during the experiment,buthad no significant difference(P> 0.05 ).The level of serum TP,ALB,GLOB,BUN,CHOL highly significantly(P<0.01) or significantly(P<0.05) decreased,Serum GLU,CREA,TCO 2 ware lower after weaning.RBC,HGB,HCT and MCV distinctly decreased(P<0.01) while MCHC distinctly increased(P<0.01)after weaning.There were no significant changes in blood RDW-CV,MCH,WBC,W-SCC,W-LCC,PLT,PDW,MPV,P-LCR.The results showed that piglets were in the condition of small RBC anaemia of nutrition deficiency at some time after weaning.
