Study on several reproductive performances of various parities in days open formulation of Fries Holland dairy cows has been conducted from January 2005 until April 2006 on North Bandung Dairy Coop (KPSBU) Lembang, West Java. The objectives of this study were to find out the influence of several parities on postpartum reproductive performance (placenta expulsion, lochia expulsion, fisrt estrus postpartum, uterine involution, intensity of estrus, second estrus postpartum, blood glucose, urea nitrogen blood, body condition score, body weight and milk yield) and days open formulation toward reproductive performance postpartum.

The study was conducted in purposive random sampling implemented by using one way classification with ninety cows postpartum which consist of thirty cows of first parity, thirty second parity and thirty third parity.

The result of the study showed that parities has a significant effect on lochia expulsion, second estrus postpartum, blood glucose, body condition score, body weight and milk yield Body condition score 3 on first parity at the third month postpartum (43,33%) is smallest on second (73,33%) and third parity (66,67%). Body weight first parity (432,87±51,50 kg) has significant effect on second (465,72±44,00 kg) and third parity (476,82±45,76 kg). Milk yield first parity (17,73±2,25 litre/day) has significant effect on second parity (21,98±3,22 litre/day) and third parity (22,59±3,98 litre/day). Furthermore these study showed that days open formulation influence by lochia expulsion performance, second estrus postpartum, blood glucose, body condition score, body weight and milk yield. First parity (106,07±38,11 days) showed that significant effect on second parity (86,23±29,00 days) and third parity (89,23±38,22 days) on days open formulation.
