Breeding With Chilled And Frozen Semen

Artificial Insemination (AI) involves the introduction of sperm into the reproductive tract of the mare without natural mating. AI in the horse was first practiced long ago. Ancient Arabian texts describe how mares were successfully inseminated. In the late 18th Century, an Italian scientist took the idea up again. He performed a series of studies in which he placed stallion semen in the snow a...

Quality of Bovine Chilled or Frozen-Thawed Semen after Addition of Omega-3 Fatty Acids Supplementation to Extender

Microbiological standards and handling codes for chilled and frozen foods. A review.

The usefulness of microbiological standards for frozen foods is now a controversy in the trade and scientific literature. Most reviewers have given arguments both for and against, and have concluded that they should be applied with great caution. Such standards have the advantage of putting questions of safety on a convenient numerical basis. Canadian workers have reported that promulgation of ...

Quality of Bovine Chilled or Frozen-Thawed Semen after Addition of Omega-3 Fatty Acids Supplementation to Extender

BACKGROUND This study was conducted to evaluate the potential protective effects of omega-3 poly unsaturated fatty acids (Ω-3 PUFAs) on bovine sperm quality in response to cooling and cryopreservation. MATERIALS AND METHODS : In this experimental study included ejaculates from five proven fertile bulls, allocated to the control and the four experimental groups. For group 1, polyethylene glyco...

Tissue Engineering: A Biological Solution for Tissue Damage, Loss or End Stage Organ Failure

In recent years the science of tissue engineering has emerged as a powerful tool for the development of a novel set of tissue replacement parts and technologies. Recent advances in the fields of biomaterials, stem cell technologies, growth factor field and biomimetics have created a unique set of opportunities for investigators to fabricate lab-grown tissues from combination of extracellular ma...
