ABSTRACT The objective of this study was to evaluate the pregnancy rate (PR) cows six farms in Bolivia and states Acre Rondônia Brazil after transfer 4,321 vitro Nellore embryos produced by a private company, 2015 2016. effects farm location, year embryo (ET), season ET, number previous ET per recipient, development stage on PR recipient cow (chi square p<0.05) were evaluated. evaluated similar, with an average 45.15%. (2015 or 2016), (rainy dry season) did not affect (p>0.05). found...
A criopreservação do sêmen bovino contribui para as cadeias produtivas leite e da carne, melhorando a eficiência dos rebanhos e, consequentemente, sua lucratividade. Neste contexto, diferentes métodos aditivos são utilizados melhorar resistência espermática à criopreservação. O objetivo deste trabalho foi avaliar o uso de ácido ascórbico (vitamina C) Trolox E sintética) como antioxidantes no meio diluidor preservar viabilidade processo congelamento-descongelamento. Oito touros, cinco Bos...
Introdução: A violência contra a mulher constitui uma manifestação do favorecimento homem em detrimento da mulher, responsável por impactos nas esferas individual e coletiva. Assim, justifica-se necessidade de ações extensionistas que visem promoção conhecimentos compreensão práticas voltadas ao cuidado desse público. Objetivo: Relatar experiência estudantes Medicina na construção execução um projeto extensão educativo, com foco potencialização conhecimento quanto às infecções sexualmente...
In the last decades, Brazilian livestock farming has undergone great expansion, based not only on quantitative growth, but also quality. The qualitative growth is factors derived from use of reproductive biotechniques, such as Vitro Embryo Production (IVEP), which allows significant genetic advancement in herd a reduced period time, by multiplication genetics higher animals. For implantation IVEP, with efficiency and viable cost, it necessary to consider some factors, well interaction...
Agribusiness, as well cattle production, contributes to the Brazilian economy, highlighting Brazil in fifth place world ranking of milk production. The Jersey breed participates this context, where females are smaller and productive, they present high concentration fat protein milk, besides needing area destined handling creation. In order for productive system be effective, there is a need reproductive follow-up animals, especially pubescent females, avoiding compromising indices, such...
It was evaluated in ovine semen pool, different cooling times (C) pre-freezing on the motility (M) and sperm vigor (V) after thawing TRT (Thermo Resistance Test). Four Santa Ines sheep were submitted to collections nine replicates. After analysis confirmation of desirable characteristics each ejaculate, a pool ejaculates four animals, diluted modified Tris-yolk, aliquoted into vales cooled for zero, one, two, three, five hours pre-freezing, frozen thawed. M V spermatozoa evaluated, before C,...
The objective of this review was to present the main difficulties encountered in cryopreservation semen, with oxidative stress being most impacting them, and demonstrate antioxidant potential Vitamins C E, as well its use cryopreserved semen dilution media. Semen is a technology great impact national livestock industry has been increasingly emphasized due advances animal breeding biotechnologies, artificial insemination, an important tool for genetic improvement several species which many...
