In two experiments, 60 individually penned growing pigs were exposed daily to two sections of cotton cord, one of which had been soaked with pigs' blood and subsequently dried, while the other was plain. The animals' preference for chewing-on the blood-impregnated cord was quantified by direct observation. When fed a standard "control" diet of corn, barley, and soybean meal with mineral and vitamin supplements, the pigs had a clear but modest preference for chewing the blood-impregnated cord. Omission of the protein supplement (soybean meal) from the diet for 4 wk led to a major increase in attraction to blood and …

Therefore, a mildly stressed animal probably needs carbohydrates (and perhaps fats) far more than supplemental protein, since the former can be quickly and easily converted into bodily fuel. And in the case of the stress induced …
