Diets for newly weaned piglets contain highly digestible ingredients (this is true for all baby animals) Limiting aa: lys, trp, thr, met, cyst. Ignore inexpensive vitamins and micronutrients that are found in feed and supplement in the diet because we are concerned about what is available in the feedstuff to the animals.
