To better understand the factors involved in erosion of sustained-release ruminal boluses, studies were conducted to determine the relationship between density of the bolus and location in the forestomachs and the influence of these factors on bolus erosion. Boluses with densities of 1.2, 1.4, 1.6, 1.8, 2.0, 2.2, and 2.4 g/cm3 were produced from inert materials and administered to 6 fistulated Hereford heifers. A minimum density of 1.6 g/cm3 was required to prevent regurgitation from the… CONTINUE READING
