Germ-free and conventional infant rats delivered by hysterectomy were reared artificially, using one of two diets--diet LNa (with a high saturated fatty acid content) and diet K 50 (with a high unsaturated fatty acid content). Animals reared for a short time (up to 5 days) after birth on the LNa diet had a low antibody (PFC = plaque-forming lymphocyte) response and low resistance to Yoshida's sarcoma. Rats reared on the K 50 diet had the same response as the suckled controls. The first 5 days after birth were found to be the decisive period for long-term consequences of nutrition.
