Abstract
- The influence of age, sex and injection of Escherichia coli lipopolysaccharide (LPS) on the plasma concentration of alpha-1 acid glycoprotein (AGP) was determined in broilers using the single radial immunodiffusion method. 2. Plasma AGP concentration increased in the 3 d after hatching, and then stabilised at 240 +/- 33 micrograms/ml up to 14 d of age. 3. No sex-related differences in plasma AGP concentration were observed up to 6 weeks of age. 4. A single injection of 900 micrograms LPS per chick resulted in a 5-fold increase in AGP concentration compared with that in saline-injected chicks. Multiple injections of LPS (200 micrograms/chick every 2 d for 14 d) caused only a 50% increase in AGP concentration.
摘要
- 采用单向放射免疫扩散法测定了年龄、性别及注射大肠杆菌脂多糖（LPS）对肉鸡血浆α-1酸性糖蛋白（AGP）浓度的影响。2. 血浆AGP浓度在孵化后3天内升高，然后在14日龄前稳定在240±33微克/毫升。3. 直到6周龄，未观察到血浆AGP浓度存在性别相关差异。4. 每只雏鸡单次注射900微克LPS，与注射生理盐水的雏鸡相比，AGP浓度增加了5倍。多次注射LPS（每2天每只雏鸡注射200微克，共注射14天）仅使AGP浓度增加了50%。
