The present study determined the effects of in ovo feeding (IOF) of N-acetyl-L-glutamate (NAG) on early intestinal development and growth performance of broilers. A total of 702 fertile broiler eggs were randomly divided into 3 treatments: 1) non-punctured control group
N-acetylglutamate (NAG) content was measured in homogenates of liver and small intestine obtained from normal and 24-h starved syngeneic mice. Subsequently, NAG was determined in normal, and in carbamyl phosphate synthetase I and ornithine transcarbamylase enzyme-deficient human liver tissue homogenates.

N-Acetyl-L-glutamate synthetase (NAG synthetase) is a mitochondrial matrix enzyme which catalyzes the synthesis of N-acetyl-Lglutamate (NAG), a physiologic activator of the urea cycle enzyme carbamylphosphate synthetase I. Deficiency of NAG synthetase in humans has been reported only three times previously.

Liver tissue from 3 patients with carbamyl phosphate synthetase I deficiency and 11 patients with ornithine transcarbamylase deficiency was analyzed by Western blots for the presence of carbamyl phosphate synthetase I and ornithine transcarbamylase cross-reactive material with anti-rat enzyme antibodies.
Nutrient availability is central for T-cell functions and immune responses. Here we report that CD8+ T-cell activation and anti-tumour responses are strongly potentiated by the non-essential amino acid Asn. Increased Asn levels enhance CD8+ T-cell activation and effector functions against
