To study the effect of feed additive N- carbamylglutamate (NCG) with different levels of feeding on amino acids profile and some analytes in serum of goats, thirty male goats aged 7-8 months were distributed into three levels of concentrate 2%, 3%, 4% with or without NCG in a 2×3 factorial experiment/ Completely Randomized Design (CRD). After 72 days of individual feeding, the blood from jugular vein was obtained before feeding in the morning. Results showed that additive NCG with 3% concentrate led to an increase (P<0.01) in total protein and albumin (P<0.05), globulins increased (P<0.01) with increasing concentrate without NCG. Creatinine decreased with increasing concentrate without NCG. Additive NCG led to a linear decrease in uric acid with increasing feed intake (P<0.05) and a linear increase without NCG. Blood magnesium, zinc, and copper increased with NCG. No difference in calcium between treatments. The level of feeding without NCG didn't affect fat parameters, while LDL, HDL, and cholesterol increased with NCG and 4% concentrate. Additive N- carbamylglutamate affected negatively blood amino acids, especially with 4% concentrate. In conclusion, 3% concentrate was the best for blood homeostasis with or without NCG, and preferred to use NCG with urea.
