摘要
为探讨酵母硒对蛋鸡组织和鸡蛋中氟苯尼考残留的影响,将180只132日龄京红1号蛋鸡随机分成两组,每组3个重复,每个重复30只。对照组饲喂基础日粮,试验组饲喂基础日粮+250 mg/kg酵母硒,连续5 d氟苯尼考以1 g/kg剂量拌料给药。收集给药第2天至停药后第14天的鸡蛋,采集停药后7 d的蛋鸡心脏、脾脏、卵巢等组织,测定氟苯尼考残留量。结果显示:与对照组相比,添加酵母硒降低了鸡蛋中氟苯尼考的最高残留量,并使鸡蛋中的氟苯尼考残留时间稍有延长;组织分布表现为卵巢中氟苯尼考含量极显著降低(P<0.01),肺脏和脾脏药物含量极显著升高(P<0.01)。综上,开产前期蛋鸡饲喂酵母硒在一定程度上延长氟苯尼考在鸡蛋中的残留时间,也会改变氟苯尼考在不同脏器中的含量分布。
To explore the effect of dietary selenium yeast on florfenicol residues in tissues of the laying hens and eggs, one hundred and eighty 132-day-age Jinghong No.1 laying hens were randomly divided into two groups with 3 replicates per group and 30 hens per replicate. The hens in the control group were fed with basal diet, experimental group was fed with basal diet supplemented with 250 mg/kg yeast selenium. Florfenicol was administered in diet with 1 g/kg for 5 consecutive days. Eggs collected from day 2 of administration to day 14 of withdrawal, and heart, spleen,ovary and other tissues obtained from day 7 of withdrawal were used for florfenicol residues detection. The results showed that adding selenium yeast reduced the highest concentration of florfenicol residues in eggs, and the residual time of florfenicol in eggs was slightly prolonged;The changes in tissue distribution showed that the drug content in ovary was significantly decreased and in spleen and lung were significantly increased(P<0.01). In conclusion, dietary selenium yeast could prolong the residue time of florfenicol in eggs to a certain extent, and also change the distribution of florfenicol in different organs.
