Risk factors for bacterial contamination during boar semen collection.
The aim of this study was to evaluate the influence of multiple factors on bacterial contamination in 213 ejaculates from four boar studs. Semen contamination by aerobic mesophiles increased in ejaculates where the preputial fluid flowed into the collection container, collection glove was dirty, preputial hair was long (>1.0 cm), the collection lasted >7 min and boars were older than 18 months....
متن کاملReproductive efficiency of a new modified boar semen extender for liquid storage
In the present study the Authors developed a new modified boar semen extender for short-term liquid storage, based on the use of amikacin sulphate and fructose rather than gentamicin and glucose. The new extender (ME-S) was evaluated and compared in vitro to commercial ones (CRONOS, TRIXcell) and to a modified extender designated for long term storage (ME-L) for progressive motility. Progressiv...
متن کاملOxidoreductive capability of boar sperm mitochondria in fresh semen and during their preservation in BTS extender.
The purpose of our study was to determine the effect of dilution and liquid-preservation of boar sperm on oxidoreductive capability of their mitochondria. The semen was diluted with BTS extender produced from water purified by destillation or by reverse osmosis. The spermatozoa were stored over a four-day period at 16-18 degrees C. The function of sperm mitochondria was assessed using the scree...
متن کاملEffect of antioxidants added to boar semen extender on the semen survival time and sperm chromatin structure.
The aim of the experiment was to determine the effect of potential antioxidants (adenosine, L-cysteine hydrochloride, ascorbic acid, magnesium fumarate and prolactin) supplementing the Biosolwens extender on semen survival time and sperm chromatin structure. The semen motility was examined every day and the susceptibility of sperm chromatin to denaturation was evaluated on collection day and da...
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...
