Braz, Karoline Maria Gil; Monteiro, Fabio Morato; Fernandes, Luana Gomes [UNESP]; Rodrigues, Naiara Nantes [UNESP]; Peixoto Jr, Kléber da CunhaMade available in DSpace on 2020-12-12T01:21:50Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-06-01; The aim of this study was to evaluate the influence of temperament on body weight and reproductive performance of Nelore bulls. Temperament of 24 young bulls was assessed by chute score (CS) and flight speed (FS). Based on the results of two consecutive evaluations (M1 and M2), bulls were divided into t...

No. of bitstreams: 0 Previous issue date: 2017-02-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Cryopreservation of bull semen is a common biotechnology procedure in cattle breeding. However, when the ejaculate is obtained by electroejaculation, wide variation is observed in the sperm/seminal plasma (SP) ratio that can affect the freez...
Avaliação de diferentes desafios espermáticos in vitro e da fertilidade in vivo...
Oliveira, Letícia Zoccolaro; Ribeiro, Lucas Bernardes; Silva, Luiz Gustavo Teodoro da; Oliveira, Clara Slade; Dias, Erika Aline RibeiroO objetivo deste estudo foi estressar células espermáticas em diferentes desafios laboratoriais e comparar os resultados in vitro com a fertilidade in vivo do sêmen. Quatro partidas de um mesmo touro Brangus foram utilizadas em um programa de IATF de 332 vacas Brangus. Cada partida foi submetida ao seguinte procedimento: a amostra de sêmen foi descongelada a 36°C por 30 segundos (grupo controle). Foram avaliado...
