Attempts were made to ascertain the factor or factors in the natural feedstuffs diet, which, in the presence of vitamin B/sub 12/, decrease the retention of S/sup 35/ by chick skeletal tissue 24 hr after administration. Also studied was the rate of S/sup 35/ uptake by various tissues of the chick as influenced by vitamin B/sub 12/. When given with vitamin B/sub 12/, as a dietary supplement or administered at the time of S/sup 35/ administration, dietary protein was found to influence uptake of S/sup 35/. Soybean oil meal, normally used in practical chick diets, gives the largest response. When soybean oil meal was compared to casein and Drackett, the higher response to S/sup 35/ uptake by the chick skeletal tissue was in the casein dietary group. The S/sup 35/ retention with the casein group, containing the highest level of sulfur amino acids, tends to minimize the body dilution theory in favor of the biological value of the protein and a possible sparing effect in relation to methionine and cysteine for protein or other synthesis. The results indicate increased retention of S/sup 35/ with increased vitamin B/sub 12/ levels, possibly through the sulfatefixing enzyme system. (TCO)
