The present study investigated the effect of sorghum grain inclusion in dairy cows diet, as an alternative to barley grain, on plasma biochemical markers (glucose, triglycerides, cholesterol, total protein, albumin, urea, creatinine, total bilirubin, calcium, phosphorus, magnesium, iron, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl transferase, lactate dehydrogenase, creatine kinase). Twelve Montbeliarde dairy cows, mid to late lactation, averaging 698 ± 27 kg body weight and 18 ± 1.3 l milk.day-1, were divided into two groups in a 43-day feeding trial: C diet, based on classical energetic sources (corn and barley) and E diet, where sorghum grain replace barley. The cows received the same forage diet. An analyzer BS-130 was used to determine the plasma parameters. Results showed that the use of 25 % sorghum grain in E diet increased (+30 %, P = 0.009) the plasma glucose and decreased the triglycerides (-20 %, P = 0.032) comparing to C diet. Total protein and albumin increased (+10 %, P = 0.002; respectively +17 %, P = 0.013) as effect of dietary sorghum addition. The calcium concentration increased (+21 %, P = 0.022), while the magnesium concentration decreased (-28 %, P = 0.010) in E diet compared to C diet. The enzymes profile slightly increased as effect of fed sorghum grain, but the differences between treatments were not significant (P > 0.05). Replacement of barley grain with sorghum had no adverse effects on health status of dairy cattle, the assessed markers being within the health reference limits.
