Antimicrobials in a rabbit semen extender: effects on reproduction
نویسندگان
چکیده
The use of fluoroquinolone antibiotics was legally restricted by the European Commission in March 2019. Since extender for rabbit semen Galap® contained this antibiotic, it became necessary to modify it. purpose study search another molecule, based on its antimicrobial activity and also conservation, motility fertility diluted with new extender. Several bacterial strains were isolated from 10 poor-quality ejaculates, including Enterococcus spp., Staphylococcus aureus Proteus spp. They then tested susceptibility. Out 15 evaluated, gentamicin one targeting such bacteria. In vivo tests carried out assess effects antibiotic change sperm parameters. Up 26 pools good quality (total >70%) original or gentamicin. Ejaculates analysed day (D) collection up 6 d storage at +17°C. After 24 h storage, reduced 7.7% compared original; decrease did not worsen storing. no difference between two media detected. A total 360 females inseminated 4 5 1:10 both extenders, following routine protocol processing centres. There female prolificacy formulations. conclusion, these preliminary results suggest that addition is useful has adverse effect prolificacy.

A sucrose-DMSO extender for freezing rabbit semen.
The aim of this study was to define a simple extender for freezing rabbit semen from selected males used to inseminate selected doses to obtain embryos for an embryo bank. Four experiments were carried out. In the first experiment, freezing extender was defined on the basis of the results of the post-thawing motility rate. Three factors and their interactions were studied: final concentration o...
متن کاملEffects of Storage Temperature and Semen Extender on Stored Canine Semen
The objective of the present study was to determine an optimum temperature and extender for short-term transport of canine ejaculated semen. There was no significant difference in the qualities of semen diluted with two kinds of extender, egg yolk Tris-citrate fructose (EYT-FC) or glucose (EYT-GC) extender, between the 2, 8 or 12 and the 4°C control groups during storage for up to 48 hr, while ...
متن کاملevaluation of a semen extender from a bioenergetic perspective 1
Four premises for sperm preservation were previously outlined. The present work tested 2 of these. The first premise was that sperm mobility phenotype affects procedural efficacy. Random bred roosters were phenotyped with the sperm mobility assay. A normal frequency distribution was observed with 35% (SD = 16.4) mobile sperm. Test subjects had values >51% (high) or between 19 and 35% (below ave...
متن کاملEffects of long-term liquid commercial semen extender and storage time on the membrane quality of boar semen
The objective of this study was to assess the sperm membrane integrity in extended boar semen during storage time using specific spectrum laboratory methods. Boar semen was diluted with the long-term liquid commercial extenders Androhep (A), Androstar (AS), Androstar plus (AS+), LD and M III and was stored up to 96 h. The sperm membrane integrity was evaluated by motility, viable spermatozoa, s...
