Resumo: | The aim of this study was to evaluate the effect of body condition (BC) on the reproductive efficiency and follicular dynamics of mares during the breeding season. We evaluated 134 mares (92 broodmares and 42 lactating) that were submitted to artificial insemination in November and December, and then put under natural controlled breeding, in alternating days, from January to March. They were kept under daily heat detection in group at field, so that at the moment it was detected, daily follicular control was initiated by rectal palpation until the detection of ovulation. The BC was evaluated in the months of August, November, January and March. Anestro rate was 26.11% and pregnancy rate was 56.7%; however, when considering only the cyclic mares, it was 77%. The number of cycles/conception was 2.3 and of mounts/cycle 2.1. The BC evolution affected (P< 0.05) the number of cyclic mares and the pregnancy rate. The month of breeding season and the BC influenced all follicular characteristics and pregnancy rate (P<0.05). We could conclude that the body condition affects the mare’s cyclical activity, follicular dynamics and fertility.KEYWORDS: Body score; equine; pregnancy rate. |

Foram acompanhadas 134 éguas (92 não lactantes e 42 lactantes) que, em novembro e dezembro, foram submetidas à inseminação artificial e, de janeiro a março, à monta natural controlada, em dias alternados. Mantidas sob rufiação diária em grupo e a campo, quando o cio era detectado, iniciou-se o controle folicular diário por palpação trans-retal até a detecção da ovulação. O escore da CC foi avaliado nos meses de agosto, novembro, janeiro e março. A taxa de anestro foi 26,11% e a de gestação 56,7%, mas, considerando-se apenas as éguas cíclicas, 77% tornaram-se gestantes. O número de ciclos/concepção foi 2,3 e de saltos/ciclo 2,1. Houve efeito (P<0,05) da evolução da CC sobre o número de éguas cíclicas e a taxa de gestação. O mês da estação de monta e a CC influenciaram todas as características foliculares e a taxa de gestação (P<0,05). Concluiu-se que a condição corporal tem efeito sobre a atividade cíclica, a dinâmica folicular e a fertilidade de éguas.PALAVRAS-CHAVE: Equino; escore corporal; taxa de gestação.Universidade Federal de Goiás2013-12-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionresearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/1769310.5216/cab.v14i4.17693Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 14 No. 4 (2013); 406-412Ciência Animal Brasileira / Brazilian Animal Science; v. 14 n. 4 (2013); 406-4121809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/17693/15620https://revistas.ufg.br/vet/article/view/17693/15621Zúccari, Carmem Estefânia S.
