How to Increase Litter Size in Rabbits
Watch for does that frequently fail to conceive, litters consistently smaller than the breed average, many stillborn kits, does that are fat or thin, bucks with poor conception rates, drops in litter size in hot months, and does with signs of disease or stress. Large numbers of does missing at palpation or test mating suggests a problem with the buck, heat or management. A sudden fall in litter size across the herd warrants a review of feed, temperature, water and health.
What I would do differently if I were starting again today
I would keep a notebook from the very first breeding, with a page for every doe and buck. I would buy stock from a breeder who could show me records, not just healthy-looking animals. I would insist on good body condition before any mating, flush the does for a week before breeding, and repeat every mating a few hours later. I would treat heat as an emergency, with shade, airflow and water ready before the hot season started. And I would be quicker to cull the does and bucks that never improved the numbers, however pleasant they were.
Litter size is not a lottery. It is the sum of choices you make before the buck and doe ever meet.
FAQ
How many kits should a rabbit have per litter?
It depends on the breed and management. Small breeds often have four to six, while medium and large meat breeds commonly have seven to nine or more. Compare with your own herd’s averages and aim to improve them.
Does feeding more increase rabbit litter size?
A short boost in nutrition before mating, called flushing, can help, especially in lean to moderate does. But overfeeding makes does fat and reduces fertility, so balance is essential.
What is double mating in rabbits?
It means mating the doe twice, usually a few hours apart or the next day, to improve ovulation and fertilization. Many breeders find it increases conception rates and litter size.
Does heat reduce rabbit litter size?
Yes. High temperatures lower buck fertility, reduce ovulation and embryo survival, and cut feed intake. Provide shade, airflow, cool water and a comfortable temperature range.
At what age do rabbits have the biggest litters?
Does usually reach peak litter size from the second to fourth litters, and performance declines as they age. Replace older or poor-performing does with productive young ones.

Big litters are built before breeding: right doe, right buck, right feed, right temperature, and a notebook to prove it.
