In Denmark, the Danish National Committee for Pig Production found out that if you sexually stimulate a sow while you artificially inseminate her, you will see a six-percent increase in the farrowing rate, which is the number of piglets produced.
Taani Rahvuslik Sigade Tootmise Komitee, avastas, et kui sa emist kunstliku viljastamise ajal seksuaalselt stimuleerid, siis on tulemuseks kuus protsenti kõrgem poegimise hulk, mis on toodetud põrsaste arv.
