Description

With swine fed on the died containing polyethyleneglycol (mol. wt. 4, 000) and chromic oxide at the constant rate, excretion variation has been observed for 5 consecutive days, and digestibility estimated by polyethyleneglycol-ratio method compared with that by chromic oxide-ratio method.<br> There was little difference in excretion variation and in variation of estimated digestibility between both these methods. However, the estimate of crude protein digesti-bility by the former method was significantly lower than that by the latter or by the conventional feces-collection method due to incomplete recovery of polyethyleneglycol in feces, the reasons for which remained to be elucidated. The digestibility estimated by polyethyleneglycol-ratio method is considered to need appropriate correction.
