Abstract Bovine semen cryopreservation is a fundamental procedure in animal reproduction. However, it associated with the production of reactive oxygen species (ROS), which can cause significant damage to spermatozoa, leading infertility and reduced sperm quality. In this context, using seminal diluents enriched antioxidants presents promising strategy for minimizing or even reversing these harmful effects. This study aimed evaluate effects different concentrations pequi (Caryocar coriaceum)...
Resumo A criopreservação de sêmen bovino é um procedimento fundamental na reprodução animal, mas está associada à produção espécies reativas oxigênio (ROS), que podem causar danos significativos aos espermatozoides. Esses estão relacionados infertilidade e diminuição da qualidade espermática. Nesse contexto, a utilização diluidores seminais enriquecidos com antioxidantes representa uma estratégia promissora para minimizar ou até reverter esses efeitos deletérios. O objetivo desse estudo foi...
The goal of the present study was to assess viability cryopreserved ovine (Ovis aries) semen, upon supplementation with α-terpineol and rosemary essential oil (Rosmarinus officinalis). collection semen from six rams formed pool, collected once a week during 7 weeks. diluted packed into straws (0.25 ml) frozen in TK 3000® device. Both were added concentrations 6.25, 12.5 25 μg/ml TRIS-yolk extender forming experimental groups; control group received only extender. samples analyzed after...
ABSTRACT Seminal plasma contains serine proteases and protease inhibitor, which are involved in mammalian fertilization, the inhibitors can be applied to prevent cold-induced sperm capacitation. The effects of different concentrations two were analyzed, Plasminogen activator inhibitor 1 - PAI-1 (70ƞg, 140ƞg 210 ƞg) Antipain (10µg, 50µg 100µg) as supplementation bovine semen cryopreservation extender. on parameters (sperm kinetics CASA, acrosome integrity, membrane mitochondrial potential,...
Objetivou-se avaliar as características morfofuncionais de sêmen criopreservado das raças touros, Nelore e Curraleiro Pé Duro. Foram utilizados vinte ejaculados quatro touros Pé-Duro, Nelore. O foi diluído em TRIS- Gema máquina TK 3000®, armazenado botijão criogênico. Após o descongelamento foram avaliados quanto à cinética espermática, integridade da membrana plasmática acrossoma, estresse oxidativo, fertilização in vitro. A análise estatística realizada utilizando SAS 2013, diferenças...
O período periparto das vacas de corte geralmente ocorre durante a estação seca, quando oferta forragem qualidade inferior é limitada, resultando em uma ingestão insuficiente nutrientes. Pesquisas anteriores mostraram que o balanço energético negativo (BEN) está relacionado ao reinício da atividade reprodutiva após parto, e liberação episódica do hormônio luteinizante (LH) fundamental para restabelecimento ciclicidade ovariana. A suplementação alimentar, especialmente com monensina, tem sido...
This study aimed to assess the impact of β-caryophyllene (BC) supplementation in extender on post-cryopreservation quality semen from Dorper rams.
O experimento foi conduzido com o objetivou de avaliar os efeitos antioxidantes da adição do eugenol no diluidor TRIS-gema para a criopreservação espermatozoides bovino.Foram utilizados vinte ejaculados quatro bovinos Curraleiro Pé-Duro, após as coletas sêmen diluído em TRIS-Gema e dividido três alíquotas; contole, tratamento nas concentrações 10µM 50µM eugenol.Posteriormente amostras foram envasadas palhetas 0,25ml criopreservadas.Em seguida mantidas equilíbrio por 60 minutos 5ºC, então...
Background: Canine sperm is a very delicate cell that quite susceptible to oxidative stress since the cytoplasm restricted and features little antioxidant reserves. Furthermore, membrane has some polyunsaturated fatty acids sensitive lipid peroxidation, which makes it important addition substances diluter aiming at decreasing such cell, particularly during seminal cryopreservation. Several antioxidants have been used in this process domestic animal’s species, however, use of palmitic acid...
The cryopreservation process causes oxidative stress to the sperm cell and addition of antioxidants semen refrigeration freezing media can help protect against damage induced by reactive oxygen species (ROS), including irreversible loss motility, lipid peroxidation DNA fragmentation, interfering in fertilization capacity. objective this work was evaluate effect Hydroxy butyltoluene (BHT) ethanolic extract stem shell Cumbretum leprosum Botucrio® diluent for equine semen. Four ejaculates four...
