The general equation and some of its implications. The Journal of Agricultural Science. 1957;48(3):379-383. doi:10.1017/S0021859600031762https://kalroerepository.kalro.org/handle/0/5108The general equation, y= 70 log x− 15, connecting y, the digestibility coefficient, to x, the percentage of crude protein in the dry matter of the feed of ruminants, which was proposed in an earlier paper, has been shown to fit all the directly determined world data for cattle, sheep and goats which have been published by Schneider (1947). It is applicable to rations composed of both single and mixed feeds for it is the total percentage of crude protein in the ration which determines its digestibility. The equation is of general application, irrespective …enhttp://creativecommons.org/licenses/by/3.0/Journal ContributionDigestibilityProteinsRuminantsCrude proteindoi:10.1017/S0021859600031762
