I did a search and found that a healthy, vigorous buck can be used 2 or 3 times in a week, up to 4 weeks. Maybe 2 does one day, one day off for the buck, then 2 more, etc. Also read on here, that best time is in the morning or early afternoon. Plus the more does that are serviced in one day, it becomes less likely that you could get big litters.
I'm new, only had one doe which the buck got her two times (magic number is 3 fall offs), but got 4 lovely kits (lion heads) at 31 days. Hoping someone one with more experience can chime in. Like Grumpy, who has a successful meat production. I know he's started some threads discussing meat production.
