Based on the results on the study it may be concluded that the growth rate of pigs is much more sensitive to energy than protein restriction in the diet. The kind of underfeeding influences the fat content in the body and pigs consuming inadequate amounts of energy have decreased, while those consuming inadequate amounts of protein have increased fat stores. The growth of internal organs is much more sensitive to energy than protein restriction and the organs whose growth in most inhibited are the liver and small intestines. Compensdatory growth takes about 2-3 weeks after the change from restriction to realimentation and a recovery of body physical and chemical composition but not age of previously underfed animals is possible
