Swine it #50: Top 5 changes in boar studs in the last 25 years - Dr Darwin Reicks
"The majority of boars, if you start varying their collection schedule, it's a stress to the boar and you'll have certain boars that will start to have bad semen quality. Keep it in mind: once a week. If you have older boars, what is common is a 3-in-2 schedule (collected 3 times in 2 weeks)."
