Bovine oocyte maturation in vitro frequently results in abnormal cytoplasmic maturation and
failure to acquire developmental competence. This is, in part, likely to be due to the non …

In this study, different combinations of 2-step, discontinuous gradient centrifugation were
used, consisting of three different combinations of isotonic Percoll (45/60, 60/75 and …

Proteins are biomolecules responsible for a vast range of functions within living cells and
tissues. Over 150 different proteins are present in the fluid of the oviduct, where mammalian …

Contents A porcine in vitro fertilization (IVF) system and seminal quality parameters of frozen–
thawed boar semen were used to assess the effectiveness of two different thawing rates of …
