The Effect of Particle Size and Phospholipid on Growth and Fat Utilization of the Baby Pig

Abstract
A semisynthetic milk was used to test the effect of particle size and phospholipids on growth and fat utilization of baby pigs. There were no significant differences in the average daily gains or feed utilization between the lots where emulsification of the fat was effected by the use of 5 percent soya lecithin. When no phospholipids were used only the 2-day-old pigs survived. Their daily gains were not different from the phospholipid-fed lots. There was no difference in the fat utilization of colostrum or no-colostrum pigs regardless of particle size when phospholipid was fed. Phospholipid appeared to be of some benefit in reducing scours. Pigs without the benefit of colostrum were successfully raised on a semisynthetic ration. Copyright © . .
