Bull Fertility and Its Relation with Density Gradient Selected Sperm
Background sperm selection is generally used to describe methods for separation of spermatozoa for in-vitro-assisted reproduction. Few studies reported relation in vivo fertility and semen parameters after selection of fertile spermatozoa; hence, our research attempt to assess different semen parameters after post-thaw (PT) or after selecting sperm sample (SSp), using density gradient separatio...
متن کاملSperm transcriptome profiling for assessment of boar semen freezability
In this project transcriptome analysis on highthroughput RNA-sequencing (RNA-Seq) data of boar spermatozoa will be utilized to identify novel genetic markers associated with semen freezability. Three boars each with poor and good semen freezability will be subjected to transcriptome studies on sperm RNA-seq data, and in combination with bioinformatics screening, will select candidate genes asso...
متن کاملSeasonal changes in reproductive activity, sperm variables and sperm freezability in Blanca Andaluza bucks
Interest in the preservation of endangered breeds such as the Blanca Andaluza goat, has increased and some steps should be therefore taken to ensure it. The study was designed to determine the seasonal reproductive pattern of Blanca Andaluza bucks, and whether this affects the quality of their semen and its freezability over the year. Seven bucks were used and their body weight, testicular weig...
متن کاملSperm Flagellum Volume Determines Freezability in Red Deer Spermatozoa
The factors affecting the inter-individual differences in sperm freezability is a major line of research in spermatology. Poor sperm freezability is mainly characterised by a low sperm velocity, which in turn is associated with low fertility rates in most animal species. Studies concerning the implications of sperm morphometry on freezability are quite limited, and most of them are based on spe...
متن کاملSperm Characteristics in Cryopreserved Buffalo Bull Semen and Field Fertility
Semen quality and its relationship to fertility are major concern in animal production. The aim of this study was to assess the relationship between frozen thawed sperm characteristics and fertility following in vivo fertility through Artificial Insemination(AI). Semen samples were collected from four buffalo bulls. Semen volume and sperm concentration appeared to be significantly different (P0...
