Estimation of Enrofloxacin Residues in Broilers Tissues Before and After Heat Treatments

Abstract

The research had been conducted to the resid assess the use of Enrofloxacin in broiler tissues before and after heat treatments. A total number of 60, on day-old broiler chicks, were given Enrofloxacin (10%) at a dose of 1ml /2 letter of drinking water at 38-40 days old. Birds had been euthanized at 41,43 and 45 days. assessment of Enrofloxacin residue was estimated in their muscles and livers before and after heat treatments. Results illustrated a significant difference of Enrofloxacin residues in pectoral muscles at 41,43 and 45 days before heat treatment and it was non-significant after heat treatment in the same days. Moreover, there were high Significant differences (P<0.01)   at boiling, grilling, and microwaves as compared with the control. Likewise, there were no significant differences of the residues in the thigh muscle between days of the study but it was highly significant (P<0.01) in comparison with boiling, grilling, and microwaves treatments at the same days of the study as compared with the control. Results revealed also no significant differences at liver tissues at the days of the study as compared with the control. Meanwhile, it was significant (P<0.05) at microwaves treatments but it was non-significant in days and it was highly significant (P<0.01) by boiling, grilling, and microwaves as compared with the control.
