A Value

An improved method for the isolation of Mucor miehei protease which utilizes a diafiltration cell has been used to obtain a highly purified protein in gram quantities and yields of about 80%. Based on a modified molecular weight function and data from amino acid analysis, a value of 41 800 for the molecular weight of the glycoprotein was established and some modification to the published amino acid composition was made. These results suggest that Mucor miehei protease is distinctly different from the two other acid proteases which are also produced by species of Mucor.

This article presents the results of a study of the amino acid composition of green protein concentrates. The technique of recalculation of formulations for the replacement of expensive protein components by the protein concentrates from green plants. The authors drafted recommendations for replacement such feed ingredients like soy, meat and bone and fish meal by cheaper green protein concentrates. According to the protein content, the soybean is proposed to replace by green protein concentrates of canola, alfalfa, fodder beet; the meat and bone meal by green protein concentrates of canola and alfalfa, fish meal by green protein concentrates of rape.

SUMMARYSamples of soya-bean meal, groundnut meal, sunflower meal and fish meal were incubated in nylon bags in the rumens of sheep receiving either whole barley or dried grass. For the vegetable sources of protein the rate of disappearance of protein was greater when they were incubated in the rumens of sheep receiving dried grass than in sheep receiving whole barley. The rate of disappearance of fish meal did not vary between sheep fed whole barley or dried grass.Rate of outflow of protein particles from the rumen was determined by rendering the protein supplement totally indigestible by a treatment with sodium dichromate. The rate of outflow was greatest with sheep receiving dried grass and increased with increasing feeding level.The mathematical expressions of degradation rate and outflow rate were combined to give the total amount of protein degraded in the rumen for the grass and barley diets at two levels of feeding.The amino acid composition of residues left in the nylon bags after 9 h of incubation were shown to be almost identical to the amino acid composition of the original protein supplement, indicating that the composition of the amino acid in the undegraded protein entering the abomasum essentially resembled that of the supplements.
