Present experiment was conducted at Livestock Research Station, College of Veterinary Science and Animal Husbandry, Kamdhenu University, Anand, Gujarat to study the performance of feeding Distillers Dried Grains with Solubles (DDGS) on milk production on 18 HF×Kankrej (75:25) advance pregnant crossbred heifers which were distributed into three treatment groups comprising of 6 animals each. Animals were offered three different types total mix rations containing 20, 10 and 0% Soy DOC and 0, 10 and 20% rice DDGS (RDDGS) in T₁, T₂ and T₃ groups, respectively. Average total WBC, Lymphocytes and Monocytes (103/μL) was non-significantly higher in T₃ (10.02±0.35, 5.59±0.24 & 0.35±0.03) as compared to T₁ (9.68±0.30, 5.48±0.21 & 0.32±0.03) and T₂ (9.26±0.32, 5.27±0.20 & 0.32±0.03) groups, respectively. RBC count (106/μL) and Hb (g/dL) of T₁, T₂ and T₃ group cows were (7.59±0.19, 7.34±0.17 & 7.11±0.16) and (9.93±0.20, 9.80±0.26 & 9.84±0.23), respectively. Serum glucose (mg/dL), Protein (g/dL), Creatinine (mg/dL) and Urea (mg/dL) in T₁, T₂ and T₃ group cows were (47.73±1.29, 53.25±1.66 & 57.28±2.07), (6.85±0.05, 7.03±0.05 & 7.34±0.04), (1.14±0.05, 1.00±0.04 & 0.94±0.02) and (40.75±0.43, 35.86±0.65 & 29.75±0.42), respectively. Average serum SGPT and SGOT of crossbred heifers that received 20% Soy DOC (T₁), 10% Soy DOC + 10% DDGS (T₂) and 20% RDDGS (T₃) was found to be (31.13±1.18, 28.28±1.38 & 30.83±1.19) and (33.05±1.08, 33.92±0.90 and 35.39±1.18) U/L, respectively, which similar among the treatment groups. Average serum calcium and phosphorus (mg/dL) was higher in T₂ (10.41±0.12 & 5.12±0.08) and T₃ (10.40±0.12 & 5.11±0.07) as compared to T₁ (10.05±2.76 & 4.94±1.40), respectively, which did not differ among the treatment groups. Hematological parameters were within normal range. Likewise, biochemical parameters viz. serum glucose and protein were within normal physiological values suggesting RDDGS as well as Soy DOC fed cows were normal and healthy.
