Reproductive Performance of Holstein Dairy Cows Grazing in Dry-summer Subtropical Climatic Conditions: Effect of Heat Stress and Heat Shock on Meiotic Competence and In vitro Fertilization
Artificial Insemination Heat Shock Oocyte Meiotic Maturation Maternal Heat Stress
2016/5/18
The present study was designed to evaluate how environmental factors in a dry-summer subtropical climate in Terceira-Azores (situated in the North Atlantic Ocean: 38° 43′ N 27° 12′ W) can affect dairy...
In vitro maturation and degeneration of domestic cat oocytes collected from ovaries stored at various temperatures
IVM feline COC apoptosis necrosis
2015/4/1
Cat oocytes have the unique ability to mature in vitro after temporary storage at 4°C which can provide opportunities to rescue oocytes from the ovaries of endangered felids after sudden death or medi...
