Resumo: | The objective of this work was to test the effect of the presence or absence of the calf in the activities of estrous, follicular dynamics and hormone secretion of Bos indicus cows. Forty and six cows were divided in 3 groups. In group with contact (CC), the calves were prevented from suckling by being confined into a pen, that allowed auditory, olfactory and visual contact of the cows with their own calves (n=17). In group without contact (SC), the calves were weaned and prevented from any contact. In control group (T), the calves weren t weaned, remaining with their mothers (n=12). The CC group showed greater ratio of cows in estrous (76.5%) when compared to T (16.7%), but no difference from SC (64.7%). The CC group showed greater ratio of ovulation (76.5%) when compared to T (33.3%) and an apparent difference (p=0.06) when compared to SC (64.7%). The duration of estrous was lesser (p = 0.04) in group CC (8.4 h + 4.4 h) than the SC (12.9 + 13.4 h), however the group T (11 + 1.4 h) was not different from the others. The average interval between weaning and onset of estrus (35 + 6.3 h), weaning and end of estrus (44.4 + 5.4 h), intensity of estrus behavior (26.6 + 24 mounts), weaning and time of ovulation (70 + 12.7 h), onset of estrus and time of ovulation (33.3 + 9.3 h) and the end of estrus and time of ovulation (23.3 + 10.3 h) were not observed differences.The T group achieved 48 + 8.4 h of interval between weaning and the LH peak while in the weaned groups (CC and SC) the average interval was of 45.3 + 10.4 h, showing no differences between the CC group (42.5 + 8.2 h) and the SC (47.5 + 11.8 h). The interval between the peak of LH and the time of the ovulation presented a general average of 24.8 + 7.7 h, showing no differences between the groups T (25.5 + 5.7 h), CC (24.9 + 8 h) and SC (24.5 + 8.6 h). It was found that the contact between cow and calf during weaning was not different from that of the cows without any contact and there was no advantage in restricting contact between cow and calf. It was confirmed that weaning has a beneficial effect on the percentage of estrous and ovulation when compared to cows not weaned. |

Quarenta e seis vacas foram divididas em 3 grupos. No grupo com contato (CC), os terneiros foram desmamados e impedidos de mamar, mas mantidos em um curral, o qual permitia contato auditivo, olfativo e visual das vacas com sua cria (n=17). No grupo sem contato (SC), os terneiros foram desmamados e impedidos de qualquer contato (n= 17). No grupo T (n=12), as crias não foram desmamadas, permanecendo juntas às suas mães, constituindo o grupo testemunha. O grupo CC (76,5%) apresentou maior proporção de vacas em estro quando comparado ao T (16,7%), mas não diferente do SC (64,7%). O grupo CC possui maior porcentagem de vacas ovuladas (76,5%) quando comparado ao T (33,3%) e uma diferença aparente (p=0,06) quando comparado ao SC (64,7%). A duração do estro foi menor (p = 0,04) no grupo CC (8,4 h + 4,4 h) quando comparado ao SC (12,9 + 13,4 h). O intervalo entre o desmame e o início do estro (35 + 6,3 h), o desmame e o final do estro (44,4 + 5,4 h), a intensidade do estro (26,6 + 24 montas), o desmame e a ovulação (70 + 12,7 h), o início do estro e a ovulação (33,3 + 9,3 h) e o final do estro e a ovulação (23,3 + 10,3 h) não foram diferentes entre os tratamentos. As vacas do grupo T obtiveram 48 + 8,4 h de intervalo entre o desmame e o pico de LH enquanto que nos grupos desmamados (CC e SC) o intervalo médio foi de 45,3 + 10,4 h, não havendo diferença entre as vacas do grupo CC (42,5 + 8,2 h) e SC (47,5 + 11,8 h). O intervalo entre o pico de LH e o momento da ovulação apresentou uma média geral de 24,8 + 7,7 h, não havendo diferença entre os grupos T (25,5 + 5,7 h), CC (24,9 + 8 h) e SC (24,5 + 8,6 h). Verificou-se que o contato da vaca com a cria durante o desmame não foi diferente das vacas sem contato algum e não houve vantagem em restringir o contato da mãe com sua cria. Ficou confirmado que o desmame exerce um efeito benéfico na porcentagem de estro e ovulação quando comparado a vacas não desmamadas.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em VeterináriaUFPelBRVeterináriaVeterináriaAmamentaçãoDesmameComportamento maternalBos indicusVacasSucklingWeaningMaternal behaviorBos indicusCowCNPQ::CIENCIAS AGRARIAS::MEDICINA VETERINARIAReinício da atividade ovariana pós-parto de vacas Bos indicus em presença ou não do terneiroResumption of postpartum ovarian activity of Bos indicus cows in the presence or not of the calfinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALdissertacao_eduardo_xavier.pdfapplication/pdf298275http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2542/1/dissertacao_eduardo_xavier.pdf4cac97edc215b060c626ac29a1665c09MD51open accessTEXTdissertacao_eduardo_xavier.pdf.txtdissertacao_eduardo_xavier.pdf.txtExtracted Texttext/plain94107http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2542/2/dissertacao_eduardo_xavier.pdf.txtf3d853db0f70cfe603738fdb056704faMD52open accessTHUMBNAILdissertacao_eduardo_xavier.pdf.jpgdissertacao_eduardo_xavier.pdf.jpgGenerated Thumbnailimage/jpeg1690http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2542/3/dissertacao_eduardo_xavier.pdf.jpg926ae52562ae470540b0a4bb8a8a8cb5MD53open access123456789/25422022-01-27 11:34:33.724open accessoai:guaiaca.ufpel.edu.br:123456789/2542Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2022-01-27T14:34:33Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
