...e damage to sperm during cryopreservation is one of the main causes of decline in fertilizing potential. Present study aimed at evaluating the role of melatonin in extender for its cryoprotective effect on post-thaw quality of buffalo bull semen. For this purpose, two consecutive ejaculates were collected from three Nili-Ravi buffalo bulls using artificial vagina at weekly intervals for a period of three weeks (three replicates). Qualifying semen ejaculates we...

...-align: justify;">During cryopreservation, the spermatozoa faces osmo-chemical, mechanical and thermal stresses, which are predominant at dilution, cooling, equilibration, freezing and thawing stages. They damage functional and morphological characteristics of sperms. Beside these exogenous stresses there is an oxidative stress which damages the spermatozoa endogenously. These stresses can be controlled with the inclusion of antioxidants in semen extender at t...

... in vitro fertilization, cryopreservation and transgenesis. Among these technologies, embryo transfer has achieved a great importance having produced numerous offspring from a genetically superior female. After the first successful transfer of mammalian embryos in 1890, it was approximately 60 years before significant progress became quite noticeable in the basic technology of embryo transfer in cattle. In embryo transfer process, embryo is collected from supe...

...ipulation, sperm sexing, cryopreservation of ovarian tissues and germ cells and embryos, and genome resource banking for mammalian species. Such biotechnologies allow more offspring to be obtained from selected parents to increase milk and meat productivity, reduce the interval between generations, therapy of diseases and conservation of endangered mammalian species. Practically, current reproductive biotechnologies are species-specific because of differences ...

...ty of sperm medium after cryopreservation. Tris-egg yolk extender with different levels (0, 4, 8, 12, and 14 mg/ml) of propolis ethanolic extract (PEE) were used. Semen was collected once/week for 20 weeks from five buffalo bulls aged 3.5–5 years. The collected semen was pooled and distributed into five equal fractions, each fraction was diluted with Tris-extender at each level of PEE (PEE0, PEE1, PEE2, PEE3, and PEE4). Semen was gradually diluted at 37â...

...t critical factor in the cryopreservation of milt. In the present study, variability between spermatological parameters of induced and non-induced C. carpio was documented for a period of 7 months. Further, the non-induced milt was stored for 24 h at three dilution ratio (1:10, 1:20 and 1:40) and spermatological parameters were analysed. Then the milt was cryopreserved with the best dilution ratio using 3 freezing protocols with two step cooling profile in pro...

Semen was collected using massage methods. This study uses a complete random design of factorial patterns with factor I being the equilibration time and factor II being the different thawing conditions. Fresh semen was evaluated macroscopically and microscopically. The sperm used had a...

The pH level increased significantly in the group O2 compared with other groups. We investigated the MDA level by thiobarbituric acid reaction (TBAR) methods, however, 2, 2 – Diphenyl - 1- picrylhydrazyl (DPPH) was used to estimate ...

Each fish species requires a specific extender because of diverse sperm characteristics. Tilapia (Oreochromis sp.) popular in Malaysia for its hardiness and rapid growth is an excellent choice for aquaculture. Aloe vera (Aloe barbadensis) (Av) shows promise in spermatogenesis, but its use as a cryoprotectant in ...
