| 摘 要： | ＡＡ肉仔鸡９２只，其中８０只于出壳１２时龄内每只鸡卵黄囊注射［３］－Ｈ－烟酸２ｃｉ；于注射后的２，４，６，８，１０，１２．１６，２０，２４，３２，４８，７２，９６，１２０，１４４和１６８小时屠宰，共１６次，每次５只鸡，测定卵黄囊、肝脏发血液中［３］Ｈ－烟酸的含量。另外１２只于出壳当日屠宰，测定卵黄囊、肝脏及血液中烟酰胺初始含量。雏鸡卵黄囊注射［３］Ｈ－烟酸后，卵黄囊、肝脏及血液中［３］Ｈ－烟酸含量下降到最大值的１／２时间分别为１１、２５和７５小时，下降到最大值的１／５时间分别为４０、１０１和１６３小时。卵黄囊烟酸含量的８０％在出壳后２天内被动用。

| Abstract: | 90 Arbor Acre broilers each was injected 2 ci[3] H-niacin to yolk sac al 12 hours old. The chickswere slaughted at 2,4,6,8,10,12,16,20,24,32,48,72,96,120,144and 168 hours after injection to determin the content of[3] H-niacin in yolk sac, liver and bloo. results showed that the contents of H- niacin in yolk sac, liver and bloo dropping to 1/2 of peak value took 11, 25 and 75 hours, respectively, and dropping to 1/5 of peak value took 40, 101 and 163 hours, respectively.
