This paper compares the effects of exposure to exogenous melatonin (MEL), short days (SD, 8h of light) and long days (LD, 16 h of light), on reproductive activity, sperm motility and other reproductive variables, in Blanca Andaluza bucks. Fourteen males were spilt into two groups of seven animals (G1 and G2). They were subjected to five alternations of 2 months of LD followed by 2 months of SD ...

In the present study, three experiments were designed to identify most appropriate technique for freezing rabbit semen. Experiment 1 aimed determine optimal levels of dimethyl sulfoxide (DMSO) contents in medium and their effects on individual bucks. Semen ejaculates each buck (n=15 bucks) mixed split into portions extension with a containing varying concentrations DMSO (0.75, 1.0, 1.4 M). Dilu...

In vivo fertility and embryos viability after cryopreservation is essential for the success of assisted reproductive techniques. The aim of this study was to investigate the impact of vitamin E (VE) +selenium (Se) or vitamin C (VC, as ascorbic acid) on in vivo fertility, embryos quality, freezing ability and culture of rabbit embryos. A total of 30 New Zealand White (NZW) rabbit does and 10 NZW...

Eriksson, B. 2000. Cryopresewation of boar semen. Studies on sperm viability in vitro and fertility. Doctoral thesis. ISSN 1401-6257. ISBN 91-576-5903-6 The world’s pig population is consistently being upgraded through the international trade of superior genetics. The two major systems that are used for this purpose are the transport of live animals and the export of frozen boar semen. The main...

Seminal plasma is comprised of the extracellular sperm milieu from spermatogenesis in the testes, through to maturation in the epididymis, as well as secretions from the accessory sex glands. Consisting primarily of proteins, this substance has a multitude of functions in mammalian reproduction. Seminal plasma influences sperm physiology, success of semen freezing, migration of spermatozoa thro...
