The study included 223 cows which were divided into three groups according to their milk yield.
The first group contains 75 cows with milk production less than (10 kgs) per cow-1 day-1, in this group 54 cows (72% ) showed normal parturition, while 21 cows (28% ) had dystocia and retained fetal membranes.
In the second group, there were 123 cows with milk production range (11-20 kgs) per cow-1 day-1, 113 cows (92% ) in this group had normal parturition, whereas 10 cows (7.9% ) only experiencing dystocia and 16 cows (13.2% ) in the same group had retained fetal membranes, with significantly difference between first and second groups at (P<0.01).
The third group contains 25 cows with milk production more than (20kgs) per cow-1 day-1, 24 cows had normal parturition (96% ), while one cow (4% ) suffered from dystocia and retained fetal membranes, with significantly difference at (P<0.01) from first and second groups.
