dc.description.abstractThe objective of the present study wits to evaluate the effect of parity on pregnancy rate in lactating Holstein cows Subjected to different synchronization protocols. A total of 96 cows (49 primiparous and 47 multiparous) were allocated randomly into four groups containing primiparous and multiparous COWS. In the PRID group (n=23), progesterone releasing intravaginal device (PRID) was inserted into anterior vagina of the cows. The devices Were removed 12 days later and 500 mu g of cloprostenol was intramuscularly administered the day before PRID withdrawal. In the Implant group (n=25), ear implants releasing norgestomet were Subcutaneously g inserted in the Car of each cow for 9 days and 500 mu g of cloprostenol was intramuscularly administered the day before the implant removal. In the GnRH group (n=24), buserelin, a GnRH analogue 10 mu g was given oil day 0 followed by the administration of 500 mu g of cloprostenol, 7 days later. In the PGF(2 alpha) group (n=24), two intramuscular administrations of 500 mu g of cloprostenol were performed at an 11-day interval. All cows exhibited oestrus signs between 36 and 124 h after the last PGF(2 alpha) administration. Mean overall pregnancy rate of the cows from the GnRH group Wits lower that that of the cows from the PRID, Implant and PGF(2 alpha) groups which were 86.9%, 72.0%1 54.2% and 83.3%, respectively. Mean pregnancy rates of the primiparous cows were not influenced by the treatment and were 83.3%, 73.3% 63.6% and 81.8% in the PRID. Implant, GnRH and PGF(2 alpha) groups. Mean pregnancy rate of the multiparous cows of the GnRH group (46.1%) was lower than that of the cows from the PRID (90.9%), and PGF(2 alpha) (84.6%) groups but was not different from that observed for the Implant group (70.0%). In conclusion. the synchronization protocols associating progesterone and PGF(2 alpha) or 2 PGF(2 alpha) administrations were more efficient than the treatment associating buserelin and PGF(2 alpha) whatever the cow's parity.en_US
