ABSTRACT
10 lactating cows were sprayed with 0.1% Neocidol solution [of 60% Diazinon] as insecticide. Milk samples were collected before [act as control] and after spraying at regularly scheduled intervals [1, 7, 14 days]. Raw and heat processed [pasteurized and boiled] milk were examined by cellulose acetate electrophoresis of milk protein proportions. Electropherograms diagrammatically presented% components of euglobulin, pseudoglobulin, component III, alpha- lactalbumin, beta-lactoglobulin, and blood serum albumin in the whey fraction, and alpha, beta and gamma-casein in casein fraction were tabulated. In addition, total protein and certain electrolytes [Na, K, Cl, Ca, P] were measured. Variable results obtained were statistically analyzed, evaluated and discussed. It is concluded that milk need at least 14 days post-spray to be safe for consumption
