About this work
Co-Ral is a new kind of agricultural chemical for parasitic grubs. There is footage of large scale cattle ranching (with farmers wearing Stetsons) and stockyards in the US. Cattle are seen in distress, running off the calories they should be consuming to gain weight as they have been infested by parasites. Footage is seen of affected beef in the slaughterhouse. The lifecycle of 'heel' flies is illustrated via animation. The action of Co-Ral is described; a farmer prepares the agent which needs to saturate the skin as the agency is systemic (works from the inside). Co-Ral also destroys the screw-worm (which can be fatal as illustrated by a dead calf). The larva and flies feed on the flesh of an open wound. Their lifecyle is shown. The cattle are also protected from other kinds of parasites. The result is happier and bigger animals - and more profit.
