「食わす」 is rough colloquial speech: it covers feeding people or animals and supporting a family, and can also mean landing a punch, while 「一杯食わす」 means pulling a fast one on someone. In everyday talk prefer 「食べさせる」 for feeding and 「騙す」 for tricking; 「食わせる」 is the more common variant of 「食わす」 itself. For blows turn to 「殴りつける」 or 「ぶん殴る」, for glossing over the truth to 「誤魔化す」, and 「給餌」 is strictly the technical term for feeding animals.
