Abstract

The effect of feed additive N- carbamylglutamate (NCG) with different feeding levels on some biochemical parameters and amino acids in the serum of goats was investigated. Thirty male goats aged 10-11 months were distributed into three levels of concentrate 70%, 50%, and 30% with or without N- carbamylglutamate (NCG) in a 2×3 factorial experiment/ Completely Randomized Design (CRD). After 77 days of individual feeding, jugular blood was sampled before morning feeding. The results showed that additive NCG with high concentrate (70%) led to a decrease (P<0.01) in total blood protein, triglycerides, and globulins, and a decrease (P<0.05) for creatinine, uric acid, and VLDL. Blood magnesium increased (P<0.01) with NCG of low concentrate (30%) treatment, while phosphor increased with NCG of 50% concentrate treatment. Calcium increased with all NCG treatments. The results of adding N- carbamylglutamate with high roughage led to a negative effect on blood amino acids. In conclusion, increasing roughage feeding without NCG is the best for blood homeostasis, and don't use N- carbamylglutamate without non-protein nitrogen additives.
