	abstract = {<p>Cryo-preservation is a critical tool to manage the logistics of implementing assisted reproductive technologies in practice, which depend upon the availability of synchronised recipient cows for embryo transfer. However, the various cryo-preservation methodologies are noted for compromising the integrity of cells within the embryo, hence reducing subsequent viability. The challenge faced by practitioners in this field isto increase the success rate of producing offspring following embryo cryopreservation.</p>

	abstract = {Advanced reproductive technologies include in vitro embryo production, cloning and genetic modification. However, only the former has been developed in deer. Considerable experimentation is required to develop cloning and transgenesis which is only justified if the deer industry foresees future potential and if animal welfare and public acceptance issues are addressed. Efficient in vitro embryo production and cloning potentially enables rapid dissemination of desired genotypes but relies on accurate identification of genetically superior individuals, which is limiting. In vitro embryo production with oocytes from elite females increases genetic gain and is further enhanced with pre-pubertal animals by shortening generation interval. Utilising sexed sperm to pre-determine gender increases reproductive efficiency. Cloning by nuclear transfer pre-determines the genotype of the animal and could effectively produce cloned stags from progenytested sires for natural breeding. Transgenesis introduces novel genetic modifications into the genome but is limited by the present poor understanding of which genes to manipulate to enhance desirable traits. The advancement of animal genomics will identify both individual genes and entire genotypes to multiply. Nevertheless, these technologies are considerably more difficult to cost-effectively implement than even poorly adopted artificial insemination in an extensive deer industry and will only be relevant for specialised markets.},

	abstract = {The commencement and course of cell proliferation is described  in proanagen hair follicles of ferrets. Initiation of autumn fur growth  was synchronised in 32 animals using melatonin implants. Skin samples  containing S-phase cells labelled in vivo with bromodeoxyuridine were  collected from groups of four animals up until the time of development  of metanagen follicles at 14 days post-implant. Cells were visualised  by an indirect immunocytochemical method and counts made of  proliferating cells in the hair germ, epithelial strand/outer root  sheath, connective tissue sheath and dermal papilla. Telogen follicles  showed no labelling in all four tissues until 4 days after melatonin  implant. The largest number of proliferating cells were in the hair  germ, which formed the new fibre and inner root sheath. The cell  labelling index for this tissue remained high at 14 days post-implant.  In other tissues, cell proliferation reached peaks during mid to late  proanagen, then declined as the metanagen state was reached. These  results indicate that some key signalling events controlling ferret hair  growth occur between 0 and 4 days after the melatonin implant, and  illustrate the separate processes of follicular regeneration and fibre  growth occurring in proanagen follicles.  },
