Prosperm® Plus semen

The natural way to boost your productivity by an average of over £18,000

  • up to 53 billion increase in sperm count
  • 5.6% improved conception rates worth up to £3,300
  • 4% increase in pigs born alive worth up to £15,125
Prosperm® Plus is a unique, feed supplement from JSR Genetics that helps to maximize the concentration and quality of boar semen.

Thoroughly researched, and successfully used to enhance the performance of our renowned JSR stud boars, this convenient daily supplement contains Hi-DHA oil, Selenium and Vitamin E. Together, these completely natural substances enhance the development of the boar’s sperm to such an effect that, from now on, AI users wanting optimum efficacy and fertility should always specify semen from boars fed with Prosperm Plus.

Improved sperm concentration

Increasing the levels of long chain polyunsaturated fatty acids (DHA) available in the boar’s feed, promotes sperm production. Trials have shown a dramatic increase in total sperm numbers of up to 53 billion1 and increases in ejaculate concentration levels of 15%. So, when purchasing Prosperm Plus AI tubes, each one offers added potency.
