Resumo: The present research aimed to evaluate the fertility rate in Nellore heifers submitted to ovarian evaluation before the beginning of the Fixed Time Artificial Insemination protocols and its impacts on the productive system. Therefore, the animals were divided into three groups after the Reproductive Tract Assessment (ATR1): anestrus (ATR1), follicle (ATR2) and corpus luteum (ATR3). and all were submitted to the same FTAI protocol. The ovarian evaluation was performed using a Mindray 2200 ultrasound device, with a frequency of 5.0 MHz. The experimental design was completely randomized and the information obtained in the field work was edited in electronic spreadsheets. After data collection, analyzes of variance were performed (p<0.05) and when significant, the chi-square test (X²) was performed at 5% probability. After analyzing the data, a significant difference was observed between the pregnancy rate of animals in anestrus compared to those with follicle and corpus luteum. Given the results of the present study, it was possible to verify that the pregnancy rate in the corpus luteum group was higher than in the other groups (ATR1 and ATR2) and obtained the best/lowest pregnancy cost (efficiency + pregnancy rate / fertility). The best strategy to optimize the fertility of bovine females was the corpus luteum group.

Para tanto, os animais foram divididos em três grupos após a Avaliação do Trato Reprodutivo (ATR): anestro (ATR1), folículo (ATR2) e corpo lúteo (ATR3). e todas foram submetidas ao mesmo protocolo de IATF. A avaliação ovariana foi realizada por aparelho de ultrassom da marca Mindray 2200, com frequência de 5,0 MHz. O delineamento experimental foi inteiramente casualizados as informações obtidas no trabalho de campo foram editadas em planilhas eletrônicas. Após a coleta dos dados foram feitas análises de variância (p<0,05) e quando significativos, foi realizado o teste de qui-quadrado (X²) a 5% de probabilidade. Após as análises dos dados foi observado uma diferença significativa entre e taxa de prenhez de animais em anestro comparado as que apresentam folículo e corpo lúteo. Diante dos resultados do presente estudo foi possível verificar que a taxa de prenhez no grupo corpo lúteo foi superior em relação aos demais grupos (ATR1 e ATR2) e obteve o melhor/menor custo de prenhez (eficiência + taxa de prenhez / fertilidade). A melhor estratégia para otimizar a fertilidade de fêmeas bovinas foi o grupo corpo lúteo.Submitted by Fernanda Castro (bib.saoluis@ueg.br) on 2025-09-10T01:54:24Z No. of bitstreams: 3 DANILLO VALENTIM MENDES.pdf: 1062737 bytes, checksum: 9535f5e7fdbc15da09ee7b4f72018e4b (MD5) TERMO DE AUTORIZAÇÃO_DANILLO VALENTIM MENDES.pdf: 329263 bytes, checksum: 083b6a1160d57dc626ed1835491fb18b (MD5) license.txt: 2109 bytes, checksum: b76a28645f58b21aeda00ac459312a65 (MD5)Approved for entry into archive by Fernanda Castro (bib.saoluis@ueg.br) on 2025-09-10T01:55:45Z (GMT) No. of bitstreams: 3 DANILLO VALENTIM MENDES.pdf: 1062737 bytes, checksum: 9535f5e7fdbc15da09ee7b4f72018e4b (MD5) TERMO DE AUTORIZAÇÃO_DANILLO VALENTIM MENDES.pdf: 329263 bytes, checksum: 083b6a1160d57dc626ed1835491fb18b (MD5) license.txt: 2109 bytes, checksum: b76a28645f58b21aeda00ac459312a65 (MD5)Made available in DSpace on 2025-09-10T01:55:45Z (GMT).
