Effects of endosulfan and amitraz on feedlot performance, carcass yield and meat quality characteristics of Nubian goats.
The pesticides endosulfan and amitraz were fed to 2 groups of Nubian goats (3 goats/group) at 5 mg/kg/d for 36 d to assess their effects on feedlot performance, carcass yield and meat quality. Growth rates, weight gains and feed conversion efficiencies were depressed insignificantly. The endosulfan-dosed group had significantly lower dressing-out percentage and both groups had significant depletions of omental and mesenteric fats. Significant reductions were also seen on body and cavity fats, the latter being severely reduced suggesting more mobilization of cavity fat than body fat. The fat-free body was homogenous with variations in the muscle/bone ratio reflected on carcass cuts. Meat quality was unaffected. Fat was the only chemical component of endosulfan-dosed total lean significantly reduced. In all parameters the effects of endosulfan were more pronounced than those of amitraz.
