  Biotechnological advances in sperm processing, AP.R

• Abstract

  Several biotechnologies are being developed to promote the conservation of the genetic material of stallions with high zootechnical value, among which we highlight the collection of sperm from the epididymis of animals who have suffered some trauma or illness preventing the collection of semen, death or euthanasia. However, these sperm cells do not come into contact with seminal plasma, w…

  Analysis of connection capacity from sperm cells from the epididymis the oviduct cells cultured in vitro in equine species, AP.R

• Abstract

  The most used biotechnique in equines in Brazil is the artificial insemination with cooled semen. Despite advances, still exist large variations of fertility results in breeding programs. There is also a great disparity between stallions in relation to semen quality after refrigeration and storage. Alternatively to this situation, the incorporation of cholesterol in the spermatic membrane…

• Abstract

  To ensure the feasibility seminal after cryopreservation, the presence of the means diluidores functioning as caps and suppliers of nutrients is extremely important. The glycerol is the crioprotetor most used for change the properties colligative water, decreasing the freezing point and increasing the survival of the cells sperm. Several works were performed with different concentrations …
