Embodiment Construction

[0013] Known porcine diluents do not solve the problems posed.

[0014] Most known porcine diluents are in powder form, however, it is practically impossible to guarantee the sterility of the powder.

[0015] In addition, despite the heavy use of gentamicin as an antibiotic in boar semen, boar semen can be heavily contaminated after three days of storage.

[0016] Porcine diluents that are both stable and concentrated liquid forms are not known.

[0017] The diluents of the present invention satisfy the identified objects and overcome the above-mentioned problems.

[0018] The diluents of the present invention are in the form of concentrated liquids. The diluent is characterized in that it contains a preservative, a liquid antibiotic formulation, at least one carbohydrate, at least one buffer, at least one salt and at least one antioxidant.

[0019] The preservative is advantageously chosen from molecules on which phosphatidic acid has been grafted to constitute phospholipi...

Abstract

A concentrated liquid extender for preserving porcine sperm cells, characterized by containing a preservative, a liquid antibiotic formulation, at least a carbohydrate, at least a buffer, at least a salt and at least an antioxidant.

Description

technical field [0001] The invention relates to a diluent for preserving pig sperm. Background technique [0002] Good reproductive hygiene is first and foremost achieved through preventive measures that limit risk factors. These measures relate to places and operations related to artificial insemination, childbirth, etc. One such preventive measure minimizes the presence and development of bacteria. These bacteria constitute the cause of contamination of the semen and uterus, with the result that the performance level of pig production facilities is severely deteriorated. [0003] When preparing semen, the diluent constitutes an important factor in maintaining the fertilization capacity of the semen dose due to its biological and bacteriological quality. [0004] Some powdered pig thinners are known. These powdered pig thinners have a number of drawbacks if they are easy to transport and store. [0005] First, they cannot be sterilized. [0006] Also, the long and ted...
