The assays were performed on 40 piglets divided into 10 equal groups. Half of the group received food with exogenous HCl. The rest of the animals served as a control. Piglets were gross anatomically examined at the age of 28, 35, 49 and 56 days of life. The content of vitamin C was determined by the method of Roe et al., (Glick, 4) and riboflavin by the method of Bessey et al. (2). Age and addition of HC1 into food did not affect the level of vitamin C in the liver of piglets. However, the content of riboflavin in the livers of piglets receiving HCl at the age of 49 and 52 days was higher comparing to control animals.
