The National Heart Lung and Blood Association reports that 500 mg is a safe daily minimum intake of sodium. This amount will be enough to maintain the bodily functions that require sodium. In an average temperate climate, a normal adult may be able to thrive with as little as 115 mg of sodium each day.
When mature, bucks weigh from 8-10 pounds and females from 9-12 pounds. New Zealand rabbits are ready to slaughter as fryers after just 2 months. Their average litter size is 8-10 bunnies.
Their combined weight is 46 pounds, so the breeder would be crossing his fingers and hoping for a litter whose individual members would achieve an adult weight of around 23 pounds each, or at least stay in the range of 19 to 28 pounds.
