The aim of this trial was to investigate the fertility of semen doses that contain sperm from either one, three or six Duroc boars.
The trial was conducted on five different farms where sows were randomly assigned to three different groups:
Group 1: Sows were inseminated with semen doses containing sperm from one boar.
Group 2: Sows were inseminated with semen doses containing sperm from three boars.
Group 3: Sows were inseminated with semen doses containing sperm from six boars.
Results revealed that when the semen dose contained sperm from several boars, litter size – measured as total born piglets
– increased by 0.3 piglets compared with doses containing sperm from just one boar. Read More...
