Previous issue date: 2014-02-26 / In cows, the "critical time" of the estrous cycle determined by the physiological state that must be defined to maintain the corpus luteum (CL) and pregnancy or luteolysis and a new estrus occurs 15 to 19 days after ovulation. The mechanisms involved in premature luteolysis and regression of the CL are not yet understood complements. It is probable that the early CL regression is related to PGF2a release mediated by the endometrium lower concentrations of P4 receptors, higher concentrations of OT receptors, or both, in the endometrium. Thus, uterine receptors for P4 and OT may influence the secretion of PGF2a from the 10th day of the cycle, during which the CL is more sensitive to the luteolytic action of PGF2a. This study aimed to evaluate the effect of exogenous OT, postpartum crossbred cows on reproductive efficiency, with emphasis on the period of maternal recognition of pregnancy. The experiment was conducted in Bom Jesus do Itabapoana, Northwest Region Fluminense between September 2013 and January 2014. Twenty- four cows were entered into a TAI program (D0 - progestin releasing intravaginal device + estradiol benzoate (EB - 2 mg, im); D8 - intravaginal device removal and application of PGF2a (0.526 mg, im); D9 - BE (1 mg, im); D10 - IA). After ovulation, cows were divided randomly into two groups: GO (n=12): oxytocin (25 IU, iv, milking morning and afternoon), GC (n=12): without OT. Sonographic evaluations were performed on days 10, 15, 18, 28 and 42. The diameter of CL was calculated as the average of the two major axes and volumes (vol) using the formula for volume of a sphere (V = 4/3p ? (D / 2) 3) where D is the average diameter (DM) of CL. On day 28 of pregnancy diagnosis, confirmed at 45 and 60 days was carried out. We observed an increase in GC DM CL between the 10th and 18th. In GO DM CL decreased among 10th and 15th and most cows expressed estrus before day 18 (9/12 - 75%), six (50%) with return to estrus between the 15th and 18th. The vol. CL was higher in cows GC at all times with a significant difference (p<0.05) compared to GO on the 15th. Cows in the CG had vol. CL higher at all times and had a higher pregnancy rate (41.7%) compared to GO (25 %). The rates of fertilization and maintenance of pregnancy until day 42 demonstrates the low reproductive efficiency in GO compared to the CG (p=0.0022). With successive inseminations at 90 days one seven cows were empty in CG (8.33%) and GO (58.3%), respectively. The pattern of development and regression of the CL confirms the involvement of OT in the reproductive activity of lactating cows. The low reproductive efficiency in GO is probably due to the action of OT, confirming the hypothesis that exogenous OT can inhibit the maternal recognition of pregnancy. / Em vacas, o ?per?odo cr?tico? do ciclo estral determinado pelo estado fisiol?gico em que deve ser definida a manuten??o do corpo l?teo (CL) e da prenhez ou a lute?lise e um novo estro ocorre 15 a 19 dias ap?s a ovula??o. Os mecanismos envolvidos com a lute?lise prematura e regress?o do CL ainda n?o est?o complemente compreendidos. ? prov?vel que a regress?o precoce do CL esteja relacionada ? libera??o de PGF2a pelo endom?trio mediada por concentra??es mais baixas de receptores de P4, maiores concentra??es de receptores de OT, ou ambos, no endom?trio. Assim, receptores uterinos para a P4 e OT podem influenciar a secre??o de PGF2a a partir do 10? dia do ciclo, per?odo em que o CL ? mais sens?vel ? a??o luteol?tica da PGF2a. Objetivou-se avaliar o efeito da OT ex?gena, no p?s-parto de vacas mesti?as sobre a efici?ncia reprodutiva, com ?nfase no per?odo do reconhecimento materno da gesta??o. O experimento foi conduzido em Bom Jesus do Itabapoana, Regi?o Noroeste Fluminense entre setembro de 2013 e janeiro de 2014. Vinte e quatro vacas foram inseridas em um programa de IATF (D0 - dispositivo intravaginal liberador de progest?geno + benzoato de estradiol (BE - 2 mg, i.m.); D8 - remo??o do dispositivo intravaginal e aplica??o de PGF2a (0,526 mg, i.m.); D9 - BE (1 mg, i.m.); D10 ? IA). Ap?s a ovula??o, as vacas foram distribu?das aleatoriamente em dois grupos: GO (n=12): 25 UI ocitocina, i.v., na ordenha da manh? e da tarde; GC (n=12): sem OT. Avalia??es ultrassonogr?ficas foram realizadas nos dias 10, 15, 18, 28 e 42. O di?metro do CL foi calculado pela m?dia dos maiores eixos e os volumes (vol.) por meio da f?rmula para volume de uma esfera (V= 4/3p x (D/2)3), em que D ? o di?metro m?dio (DM) do CL. No dia 28 foi realizado o diagn?stico da gesta??o, confirmada aos 45 e 60 dias. Observou-se no GC um aumento do DM do CL entre os dias 10 e 18. No GO o DM do CL diminuiu entre os dias 10 e 15 e a maioria das vacas manifestaram cio antes do dia 18 (9/12 ? 75%), sendo seis (50%) com retorno ao cio entre os dias 15 e 18. O vol. do CL foi maior nas vacas do GC em todos os momentos com diferen?a significativa (p<0,05) em rela??o ao GO no dia 15. As vacas do GC tiveram o vol. do CL maior em todos os momentos e obtiveram uma maior taxa de prenhez (41,7%) comparativamente ao GO (25%). As taxas de fecunda??o e manuten??o da gesta??o at? o 42o dias evidencia a baixa efici?ncia reprodutiva no GO em rela??o ao GC (p=0,0022). Com sucessivas insemina??es aos 90 dias uma e sete vacas estavam vazias no GC (8,33%) e GO (58,3%), respectivamente. O padr?o de desenvolvimento e regress?o do CL confirma o envolvimento da OT na atividade reprodutiva de vacas em lacta??o. A baixa efici?ncia reprodutiva no GO deve-se provavelmente ? a??o da OT, confirmando a hip?tese de que a OT ex?gena pode inibir o reconhecimento materno da gesta??o.
