A bolus 10 suitable for enteral feeding comprising a generally tubular body, optionally the same diameter as the feeding tube, a posterior end 26 which can either attach to the downstream end of a feeding tube via a shank 25 or other method or be formed integrally with the tube, a side wall 21 with at least two openings 30 suitable for fluid transfer, and an anterior end 14 which may have no openings. The sidewall openings can be on opposite sides and can be located within recesses 34, 38 with edges which converge and can intersect, forming an aperture which can be substantially triangular and perpendicular with the longitudinal axis, and the tubular body can comprise a main channel 27 between the posterior and the fluid openings with an optionally rounded septum 33 dividing the flow between the openings.
