I think rearing the young is hard on the female, and since they breed right back after giving birth I would assume 12 months is the beginning of the decline. Their life span is supposed to be 2 to 3 years, but I can't believe the females can last that long. I've been told that litter size starts to decrease as the females age, so that is an indication that replacements should be kept. If more than a single female gives birth at the same time it may be easier on the females.
