| The present study was carried out at local buffalo flock in AL-Najaf province , by using data collected for 40 reverine buffalo in different lactation stage thought the year 2013 to determine the effect of lactation stage and sex of birth in milk protein , lipids , lactose ,ash solid not fat ,calcium ,density, freezing point and water. Results was showed a significant effect (p≤ 0.05 ) of lactation stage in milk lipids, protein, ash and freezing point , the highest values were in late period of lactation (9.5g/l ,4.0 g/l ,0.84 g/l and -29.85 c°) respectively. Lactose and density were increased significantly (p≤ 0.05 ) in the beginning of lactation period its about 4.53 g/l and 54.33ml/gm respectively compared with end of lactation period its about 3.38 g/l and 43.67 ml/ gm respectively. S.N.F ,calcium and water were not affected significantly by lactation stage. Significant effect (p≤ 0.05 ) of calve sex in milk lipids, protein and freezing point , the highest values were in milk of dams that calved female (7.83g/l ,3.92 g/l and -27.36c°) respectively. Lactose and density were increased significantly (p≤ 0.05 ) in the milk of dams that calved male its about 4.62 g/l and 53.17ml/gm respectively. S.N.F ,calcium, ash and water were not affected significantly by calve sex. | ||
