Повний текст джерелаFrozen-thawed boar sperm has the potential to impact the future of the swine industry. The objectives of the study were to characterise semen of Kolbroek and Large White boars, find a suitable holding temperature and extender, determine the effect of breed and pregnancy rate following artificial insemination by frozen-thawed boar semen. A total of eight boars and 33 sows were used in this study. The 120 ejaculates were collected from each individual Kolbroek and Large White boars with the gloved-hand technique. Macroscopic and microscopic sperm characteristics were recorded. The bodyweight of Kolbroek (154.7 kg) was significantly lower compared to Large White (189.9 kg) boar. However, no significant differences were observed in Kolbroek and Large White boar semen volume (140 and 170 ml), sperm concentration (0.727 and 0.761 x 109 sperm/ml), and total sperm motility (95 and 91%). A positive correlation existed between bodyweight and semen volume of Kolbroek (r= 0.22) and Large White (r= 0.26). Conversely, the bodyweight of Large White was positively correlated to sperm concentration of Large White (r= 0.37) but negatively correlated to Kolbroek (r= -0.66). Storage time and temperature did not affect Large White boar sperm motility rate. However, Kolbroek sperm total motility rate (61.0%) was affected at 25°C after 24 hours. The highest total sperm motility rate was observed for semen diluted with Tris-based extender (74.1%) in Kolbroek boars at 48 hours of storage. Large White boar semen diluted with BTS (62.9%), Kobidil+ (69.3%) and Tris (65.1%) showed significantly higher sperm motility rate at 48 hours of storage, compared to Citrate (27.6%) extender. Cryopreservation significantly reduced sperm motility rate for Kolbroek (30.2%) and Large White (24.0%) boars. However, a high pregnancy rate was recorded in both sows of inseminated with raw diluted (100% vs. 81.3%) and frozen-thawed (50% vs. 50%) semen of Kolbroek and Large White boars. In conclusion, the bodyweight of Kolbroek and Large White boar was positively correlated with ejaculated semen volume. Kolbroek and Large White boar sperm stored at 18°C for 24 hours maintained the acceptable sperm motility rate. Kolbroek boar semen diluted with Tris-based extender maintained high sperm motility rate. Cryopreservation significantly reduced sperm motility rate regardless of breed; however, pregnancy rate from frozen-thawed semen was high for Kolbroek (50%) and Large White (50%) even though the frozen-thawed fertility was low.

Повний текст джерелаThis project involves a detailed study of three South African antelope species, springbok, impala and blesbok. The study investigates the origins of sperm in terms of testicular histology and subsequently the major storage organ, the cauda epididymis. Sperm of these species were characterized in terms of their quality (morphology, motility, vitality characteristics among others and their physiology: when exposed to different media and cryopreservation protocols. Finally sperm fertilization biology of the three species and evaluation of fertilization and developmental success when using homologous and heterologous oocytes (relative comparison) were assessed. Cauda epididymal spermatozoa was recovered post-mortem from the testes of culled springbok (n =38); impala (n =26) and blesbok (n =42) during winter months in South Africa and cryopreserved in a Tris-fructose-citric acid extender (Biladyl) supplemented with 20% egg yolk and 7% glycerol under field conditions. Longevity of sperm was assessed in Tris and Citrate extenders and modified Tyrode lactate in vitro fertilization (IVF) media. Oocytes were collected from the ovaries of domestic cows (n =165), springbok (n = 72) and blesbok (n = 42) and matured in domestic cattle M199 maturation media supplemented with 10% FCS, 10IJg/mi LH, 10IJg/mi FSH and antibiotics. Heterologous (zona intact and zona free) and homologous fertilization was carried using a domestic cattle IVF protocol. Results were analysed using SPSS version 18.0 (Statcon, South Africa). Interspecies comparisons were made using parametric tests: paired t-test for the freezing effect, one-way analysis of variance (ANOVA), Mixed between-within subjects ANOVA for longevity, Non Parametric test for motility characteristics and least squares ANOVA for...

Повний текст джерелаClimate change, loss of habitat and over-exploitation of natural resources as well as the introduction of invasive alien species through human activities are resulting in an ever increasing risk of extinction of many plant and animal species. There are two major approaches to conserving threatened and endangered species. Firstly the large scale preservation of natural habitat and ecological processes, thereby protecting the species inhabiting the habitat. The second approach involves the ex-situ breeding of rare and endangered species. It is estimated that in the next 200 years approximately 800 mammalian species will require the assistance of breeding programs to ensure long term genetic viability. Biological Resource Banks (BRB) can potentially contribute to this challenge by providing a source of genes that can be used to counter the effects of external selection pressures, genetic drift and inbreeding depression in small or fragmented populations. These banks commonly contain biological materials such as cryopreserved sperm, embryos and cell cultures mainly as genetic and research resources. . Biological resource banks can potentially use these cryopreserved gametes together with assisted reproductive technologies (ART), such as artificial insemination (AI), in vitro fertilisation (IVF), embryo transfer (ET), intracytoplasmic sperm injection (ICSI) and nuclear transfer (NT) to maintain genetic heterogeneity in ex-situ and wild populations. Ascertaining the appropriate protocols for developing the ARTs necessary for non-domestic species is one of the major challenges faced by reproductive physiologists. Typically, there is very little available information about the processing of semen, the effects of diluents, concentration and type of cryoprotectants and freeze-thaw methods for sperm samples of non-domestic species. Procedures proven to be highly effective in humans and laboratory or domestic species, are frequently adopted and modified for use in related wildlife species. It is thus necessary to gain knowledge of the reproductive physiology of wildlife species in order to define effective protocols for the cryopreservation of biomaterials which assists in the conservation of South Africa‘s diverse wildlife species. Sperm quality assessment is a useful tool for assessing the reproductive health of free-ranging populations as well as for selecting individuals for future assisted reproduction programs.

Повний текст джерелаThe spermatogenesis of two freshwater species from South Africa, Barbus marequensis and B. polylepis, and three fresh water species from Israel, B. canis, B. longiceps and Capoeta damascina, was studied. A histological comparison of the process of spermatogenesis was undertaken. The breeding cycle of B. marequensis, B. polylepis, B. canis, B. longiceps and C. damascina was similar to the breeding cycle of B. aeneus and four phases occured within the cycle. The four distinctive phases are post spawning phase, rest phase, pre-spawning phase and the spawning phase (Vlok, 1986) . During the post spawning phase a decline in sperm development is observed and possible lisosomal activity is responsible for the resorption of sperm cells not shed during the spawning phase. The presence of collagen structure provides a distinctive character to the tissue of the testis. The resting phase is characterised by the absence of the lobular structure and the testis is dominated by the collagen tissue. The testis is small and unobtrusive in the abdominal cavities of both species. At the onset of the pre-spawning phase, the testis is filled with spermatogonia. The lobular structure becomes more prominent and the interstitial tissue can be distinguished. Later during the phase, the synchronised development of sperm cells in the cysts of the lobules can be observed, whilst sperm cells in adjacent lobules are in different stages of development. During the spawning phase the testis of all species studied contain mature sperm . cells in the lumens of the lobules.
