  ABSTRACT: Our objectives were to measure glutamine (Gln) and glutamate (Glu) concentrations in the milk and blood of lactating Holstein cows, as well as milk composition and somatic cell count (SCC) throughout different stages of lactation. Samples were collected from 21 cows in the 1st, 2nd, 3rd, 5th and 10th months of lactation. It analyzed Gln and Glu in the blood and Gln, Glu, lactose, fat, protein and somatic cells in the milk. Also, it measured Gln and Glu in blood from these dairy cows’ calves. Results were analyzed using one-way ANOVA, T-test and Tukey’s test, with a 5% significance level. There was a difference in blood [Gln] in from dairy cows (P nd (~0.181 μmol/mL) and 5th (~0.190 μmol/mL) months of lactation and the highest at 10th month (~0.276 μmol/mL). Also there was a higher protein content in the 5th and 10th months of lactation (~3.61% each) when compared to the other months (P
