The goals of the reproduction platform are: (1) to help the genetic improvement group with tools and knowledge about fertility so that further genetic improvement can be realised, (2) to help clients realise the genetic potential of the animals without risks of disease transfer and (3) to help the AI centres be as cost efficient and quality oriented as possible.

Projects are organised into two groups: male reproduction and female reproduction.

AI dissemination the basis for success

Artificial Insemination (AI) itself cannot improve the genetic capacity for feed conversion ratio (FCR). But ultimately, with the help of advanced semen dilution techniques, the very best boar could serve for 10,000 sows. That would revolutionize FCR.

Better AI to benefit more from top genetics

AIM Worldwide, Topigs Norsvins’ AI department, is continuously developing new and innovative ways of realising better AI. The next challenge is to produce more semen per boar.

From insemination to farrowing – Understanding litter size

The number of piglets born is the result of ovulations, fertilisation and survival in the uterus. AI quality is so high now that virtually all ovulations result in a fertilised egg that starts cell division.
