Viabilidade dos espermatozoides criopreservados de touros colhidos do epidídimo após 12 horas a 4ºC

Abstract: ResumoO objetivo deste estudo foi avaliar o efeito da refrigeração do epidídimo, sobre a viabilidade dos espermatozoides congelados. Foram colhidos dez pares de testículos/epidídimos de um abatedouro comercial. Um dos epidídimos foi refrigerado a 4°C durante 12 horas e o contralateral foi imediatamente processado. O epidídimo foi isolado, as células espermáticas extraídas e analisadas quanto à motilidade, vigor, concentração, morfologia e integridade da membrana. Após a análise, os espermatozoides foram congel… Show more

“…Usually, for DNA extraction from other cells such as blood samples, a volume of 200 μL to 1 mL or a total number of cells greater than or equal to 1x108 cells are used (GE manual, 2007). However, unlike other animal species such as bovine (Scott et al, 2016;Scott et al, 2018), dog's ejaculate volume and sperm concentration are low, requiring technique improvement that allows DNA extraction from smaller volumes and subsequent qPCR.…”
