Extender based on caseins with addition of Cholesterol. Milk casein posphoproteins protect sperm cells from the action of seminal plasma proteins (HSP-1, HSP-2) and Ca ions, prolonging spermatic longevity favoring semen transport. The temperature of 5°C or 15°C can be used for semen cooled transport as well as for pre-freezing centrifugation. Use dilutions of 50 million/ml for cooled transport, respecting the minimum of 2 parts of extender to 1 part of semen. In case of samples requiring...

  Extender based on skimmed milk with addition of Pentoxifylline which inhibits phosphodiesterase by increaseing of APMc responsible for the control of ATP production. Ideal for fresh insemination or cooled semen transport at 5°C only. Use dilutions of 30 to 50 million/ml for cooled transport, respecting the minimum of 2 parts of extender to 1 part of semen. In case of samples requiring centrifugation before cooled transport, resuspend the sperm also between 30 to 50 million/ml. Suitable...

  Extender based on skimmed milk to transport cooled semen or preservation at 5° C or 15° C, as well as for centrifugation pre-freezing. Use dilutions of 30 to 50 million/ml for cooled transport, respecting the minimum of 2 parts of extender to 1 part of semen. In case of samples requiring centrifugatoin before cooled transport, resuspend the sperm also between 30 to 50 million/ml. Suitable for most stallions, best cost/benefit ratio.

The formulation of BotuCrio contains a lower concentration of Glycerol and, in combination with one of several amides, results in better sperm integrity, sperm viability, better post thaw total and progressive motility, as well as sperm velocity, compared to other commercially available freezing extenders.
