Abstract:

This experiment was conducted to study the residue dynamics of oil adjuvant in eggs and chicken. One hundred and twenty 1-day-old Jingfen layer chickens were raised. Every group was allocated into 12 replicates and 10 layer chickens per replicate. All the right wing shoulder muscle was injected in accordance with the recommended injection dose of oil adjuvant vaccine immune program. 3 eggs were collected randomly from every replicate of group at 159, 166, 180, 201, 235, and 271 d to measure the residual of n-alkanes and PAHs. Six chickens were chosen randomly from group to slaughter at 280, 330, 380, 430 d, collecting right wing shoulder muscle, left thorax muscle, right thorax muscle, left leg muscle, right leg muscle, liver and kidney to measure the residual of n-alkanes and PAHs. The results showed as follows: The alkanes with smaller molecular weight of mineral oil, such as n-hexadecane, n-heptadecane, n-octadecane, were easier to metabolize and transfer to other part of chicken. The amount of mineral oil in injection site was most, the residue amount of liver and kidney also more by general circulation, and residue elimination rate was slower. n-alkanes and PAHs in all samples were declined as time goes on. Then it had not detected PHAs in egg. The mineral oil transferred to eggs is too little, which has no effect on the egg quality. The mineral oil residue time in the chicken body is long, the long chain alkanes eliminated and migrated need more time to metabolized completely in the chicken.
