The effect of replacing (5, 10, and 15%) wheat middlings in the feed of broiler chickens (EX5, EX10, EX15) with wheat germ expeller (WGE) on their parameters of carbohydrate, lipid, and protein metabolism was examined. Thirty-two randomly chosen broilers on day 43 were slaughtered, and their blood and liver were sampled. The concentration of glucose, triglycerides, total cholesterol, and protein and their fractions were tested in the blood serum. In livers, total protein and fat contents were analyzed. It has been found that replacing wheat middlings with 10% and 15% of expeller results in (<i>p</i> ≤ 0.05) a lower final body weight than CT. A higher feed, fat, protein, and methionine intake was noted in groups EX5-EX15 compared to CT. No alterations were found in the protein and fat content in the livers and the blood lipid profile of chickens. Changes in the protein metabolism of broilers indicate the need to research. WGE does not interfere with the metabolism of carbohydrates and lipids. However, WGE did not contribute to obtaining production benefits.
