Resumo: This study has the objective of evaluating the efficiency of a dose of 1 mL (250 ?g of cloprostenol) in the vulvar submucous, in the group 2 (G2) of 25 cows, in relation to an intramuscular dose of 2 mL (500 ?g of cloprostenol) formed by the group 1 (G1) of 24 cows ½ Nelore-Chianina, totaling 49 female repeatbreeders. The cows were with at least 120 days period post partum remaining in the reproductive season between December 2003 and February 2004. The application of cloprostenol was repeated eleven days after in the cows did not show estrus until 5 days of the first dose. The total percentage of estrus were of 79.16% (G1) and 56% (G2). The media of the hours for estrus being present was of 81.35 hours (first dose) and 92.8 hours (second dose) and 71.5 hours (first dose) and 76.1 hours (second dose) for G1 and G2 respectively. In relation to the media hours for the presence of estrus, in the groups G1 and G2 for first dose, second dose, and for the total number of cows in estrus, there were no significant difference (p>0.05). The artificial inseminations were performed 12 hours after the appearance of estrus and the gestation diagnostic at 53 days after the last insemination by means of rectal palpation confirmed by transrectal ultrasonography where 20 cows were diagnosed as gestating. Ten in the G1 and ten in the G2 totaling 40.8% gestating. The strategic application of cloprostenol is suggested for the cows repeatbreeders at the end of the reproductive season.

Foi utilizada dose de 1 mL (250 ?g de cloprostenol) na submucosa vulvar no grupo 2 (G2) = 25 vacas; e dose clássica de 2 mL (500 ?g de cloprostenol) intramuscular, formado pelo grupo 1 (G1) = 24 vacas meio sangue Nelore-Chianina, totalizando 49 fêmeas “repeat-breeders”, com escore corporal 3,5 (1 a 5), sem alterações ao exame ginecológico. As vacas se encontravam com 175±13 dias de período pósparto, mantidas em estação de cobertura durante 89 dias, entre Dezembro de 2003 e Fevereiro de 2004. Foram inseminadas uma vez, seguidas por duas a três coberturas naturais, efetuadas por touros aptos após exame andrológico, acasalados na proporção de 1:20. A aplicação de cloprostenol foi repetida 11 dias após a primeira dose, nas vacas que não apresentaram estro. Realizou-se rufiação 2 vezes ao dia, durante cinco dias após a aplicação de qualquer dose de cloprostenol. As percentagens totais de estro foram de 79,16%(G1) e 56%(G2). A média de horas para a apresentação do estro foi de 81,35h (1ª dose) e 92,8h (2ª dose) para o G1; e de 76,1h (1ª dose) e 71,5h (2ª dose) para o G2. Com relação à média de horas para a manifestação do estro nos grupos G1 e G2 para a 1ª dose, 2ª dose e para o total de vacas no estro, não houve diferença significativa (p>0,05). As inseminações artificiais foram realizadas 12h após a observação do estro e o diagnóstico de gestação aos 53 dias após a última inseminação, por meio de palpação retal, confirmado com ultra-sonografia transretal, sendo diagnosticadas 20 vacas gestantes, dez no G1 e dez no G2, perfazendo 40,8% de gestações. Não houve diferença entre o total de vacas gestantes nos dois grupos. Sugere-se a aplicação estratégica da meia dose de cloprostenol na submucosa vulvar para a indução do estro em vacas “repeat-breeders”, ao término da estação de cobertura.UEL2005-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/231510.5433/1679-0359.2005v26n3p387Semina: Ciências Agrárias; Vol. 26 No. 3 (2005); 387-394Semina: Ciências Agrárias; v. 26 n. 3 (2005); 387-3941679-03591676-546Xreponame:Semina.
