The effects of different doses of PGF2a administrations and estrous detection methods on pregnancy rates in cows
Abstract
Theaim of this study was to evaluate the effects of different PGF2()(,regimens and estrous detection techniques onthe pregnancy rates in cows. In the study, 45 healthy cows which had completed a postparturientlcast one detectable estrous were used as the materia . Cows were divided into 3 groups each consisting of 15 cows randomly. A 6-8MI-/z. multiple frequenceprobe attached, B Mode Rea -time ultrasonographydone to the cows having a matllre corpus luteum and dominant fo IIicle at any time at the cycle. Contrary, two PGF2()(injeetions weremade on day 7 of the estrous cycle with a 7 hours interva in Group II. Group III (control group) only detections were made withoutany hormone trcatmentsfrom dayi7 and on. Estrous detections were conductedtrumenls and RP/USG techniques in all groups. All estrous detected cows were artificially inseminated af ter i2 hours. Pregnancy esıimalİons were done with USG after 3 weeks and rectal palpationafter 40 days. As a result, no significantdifferences ..in preovu laloric follicle diameters were observed between PG treated groups and control s (p=0,08 I). Any relations between the diameterof the preovulatoricdetecıion was found lo be RP/USG methods(%j00) and it eould be advised to use the other two techniques combined with the formel", for ıhis manner. Pregnancyrates did not differ in both 3 groups. Thereby, neilher the hormonc treatmentsnor the estrous detection teehniques are found to be effective on pregnaney rates
