The aim of this research is to determine the effect of sex of calve and parity on milk production and chemical composition in Iraqi buffalo milk. This study included 300 milk samples from 100 buffaloes in Al-Mishkhab district / Najaf Governorate during the period from January to June 2019. The results have appeared that sex has a high significant (P<0.01) effect on production of milk, where the higher production is recorded for the milk of animals with male births (1568.936/L±30.966) compared to animals with female births (1377.649/L ±28.993) and a significant effect of sex of calve is recorded on total solid compounds. A high significant(P<0.01) effect of parity is recorded on both milk production and total solids, The higher average milk production is recorded for the Larger animals. At the same time, parity had a significant effect on milk fat and minerals.
