The effect of adding gelatin on sedimentation and maintenance of forward motility in boar spermatozoa stored at +12 degrees C in a skim milk diluent and in a centrifuged egg yolk-citrate diluent.


, : The effect of adding gelatin on sedimentation and maintenance of forward motility in boar spermatozoa stored at +12 degrees C in a skim milk diluent and in a centrifuged egg yolk-citrate diluent.. Berl. Munch. tierarztl. Wschr, 75: 284-287

A further series of small experiments on the preservation of boar semen is briefly described. A total of 36 ejaculates from 4 boars was used. In both diluents the addition of gelatin influenced sedimentation; amounts of 350 mg. per 100 ml. diluent reduced it considerably and 525 mg. prevented it completely. During storage up to 120 hrs., sperm motility was reduced in samples containing gelatin compared with samples without it.
