Aim: The aim was to determine the antioxidative capacity of vitamin E, vitamin C and their combination (vitamin E+C) on standard semen parameters i.e., mortality, percent live sperms, percent abnormal sperms and acrosomal integrity in cryopreserved Bhadawari bull semen. Materials and Methods: Ejaculates collected from four Bhadawari bulls were evaluated and later pooled at 37°C. Pooled semen sa...

BACKGROUND European bison is the largest mammal in Europe with the population of approximately 4000 individuals. However, there is no report of post-mortem spermatozoa collection and cryopreservation from this species and the aim of this study was to test if the epididymal spermatozoa collected post-mortem from European bison are suitable for cryopreservation and artificial insemination (AI). ...

The present study was aimed to determine the effect of GnRH analogue [des-Gly10, D-Ala6]-LH-RH ethylamide on the quality of rabbit spermatozoa stored at 17°C for 3 days. Semen from 5 bucks (13 ejaculates) was used in the experiment. Ejaculates were divided and diluted at a 1:10 ratio with rabbit semen extender Galap (IMV, France) (Control) or with Galap extender supplemented with GnRH analogue ...

BACKGROUND Variability among stallions in terms of semen cryopreservation quality renders it difficult to arrive at a standardized cryopreservation method. Different extenders and processing techniques (such us colloidal centrifugation) are used in order to optimize post-thaw sperm quality. Sperm chromatin integrity analysis is an effective tool for assessing such quality. The aim of the presen...

In order to protect the spermatozoa against cold shock, hen egg yolk is widely used as a cryoprotective agent in semen freezing extenders for domestic animals. The protective action of yolk is largely presumed to be due to low density lipoproteins (LDL). The effects of LDL on sperm quality of bull and northern pike (Esox lucius) after freezing-thawing have been reported, but no study has been m...

Quality of fresh milt of grey mullet Mugil cephalus Linnaeus, 1758 was assessed based on motility grade, motility duration, sperm count and seminal plasma osmolality. Freshly collected milt from live males (n=17) were examined individually for motility assessment. Motility grade was four in fifteen samples whereas three in other two samples analysed. Other sperm quality parameters such as motil...

Supercompact extender based forcings are used to construct models with HOD cardinal structure different from those of V . In particular, a model with all regular uncountable cardinals measurable in HOD is constructed.

Fertilization and development of the preimplantation embryo is under genetic control. The present goal was to test 434 single nucleotide polymorphisms (SNPs) for association with genetic variation in fertilization and early embryonic development. The approach was to produce embryos from 93 bulls using in vitro procedures (n = 3-6 replicates per bull) and relate cleavage rate (CR) and developmen...

Antibiotics are added to semen extenders to take care of heavy microbial load, however, their continuous use poses a constant threat of developing antibiotic resistance by the common microbes present in the semen. Our hypothesis was that natural honey, having antibacterial activity and rich in fructose could replace the use of antibiotics and fructose in the semen extender. Twenty-four ejaculat...
