Thirty Dalagh breed male lambs were separated from their mothers on 3±1 days of age and divided into 6 groups (5 lambs per treatment), and reared in individual cages. Lambs were fed with 6 treatment diets for 90 days age. Treatment diets consisted of 2 fluid feed (ewe milk and milk replacer) and 3 starter diets, 1: 100% concentrate, 2: 67% concentrate and 33% alfalfa hay and 3: 33% concentrate and 67% alfalfa hay. Data were analyzed as a completely randomized design according to 3×2 factorial method. Average of rumen fluid pH, total volatile fatty acids (TVFA), ammonia nitrogen (NH3-N), blood urea nitrogen (BUN), beta hydroxyl butyrate (BHBA), urinary purine derivative excretion (PD), microbial purines (MPD) and microbial nitrogen supply (MN) in lambs fed with ewe milk and milk replacer did not show any significant differences (P>0.05).
