BREEDING
1. Pick a pair. If you are breeding for color and quality, you need to choose mates carefully.
..... The Buck. He is the most important member of your herd. You should acquire the very best bucks you can afford. He should be show quality type per the Standard of Perfection. Color is secondary depending on your breeding program. An unshowable variety can be useful for producing proper color. In this case, he's considered a "brood buck" instead of a show bunny. Keep in mind that a very expensive buck isn't always necessary or even productive. Some breeders' lines are so tight, he may not "mesh" with your does. It's often best to buy a pair or trio (1 buck, 2 does) from such tightly-bred lines to increase the odds that those fine genes will be introduced to your herd. I prefer small bucks as they will produce more show quality type than a buck who pushes the weight limit. While a larger buck can produce good offspring, it limits his usefulness with larger false dwarf does. Large false dwarf bucks have no real use except as pets.
..... The Doe. She, of course, is very important as well. She can be either a true dwarf show bunny, or a large false dwarf. We call the large doe "brood doe" or BUD (Big Ugly Doe). The BUDs are the baby makers. They are built for having larger litters and usually produce more easily than a small doe. BUDs will throw false dwarfs, but if you put her with a small buck, the odds are good for some show quality offspring. Sometimes, the biggest ugliest doe with the muttiest pedigree will allow most any buck to shine. The small show doe will have a harder time giving birth, and the litters will be smaller. A larger buck could hurt a small doe, and if the kits are too large, it will probably be a failure. If a small doe has proven to have litters easily, you can try a larger buck if needed.
2. Put them together. Ok, not that simple. While rabbits can mate at any time, they don't always "breed like rabbits". Bucks are almost always up for it, but a doe has to be "in the mood". I said "almost" in regard to bucks. There are those guys who are less studly, and like to play kissy-face instead of getting down to business. These gentlemen need an eager doe. I'll get to that in a minute.
..... Who goes where. Always put the doe in the buck's cage. He's settled there, and will go after the doe immediately. The doe can be very territorial about her cage, and may fight the buck if you put him in hers. Putting them both in a strange cage could slow the process while the buck sniffs around to see who else has been there. If you want to use another cage, put the buck in it well before you add the doe.
..... What happens next. Watch. If the doe is receptive, she will immediately signal this by flattening her body and raising her tail. The buck will usually mount right away. It's over in a few seconds. When finished, the buck will tuck and roll off the doe, often with a squeak. Afterward, there is usually more loveplay, and the buck may mount her several times. If the doe is very eager, she may mount him as well. A doe who is ready will sometimes give signs before she is put with the buck. If she flattens while you are petting her, or her vent is red and swollen, she's ready!
..... She doesn't wanna. If the doe is not receptive, she won't allow the buck to mount. She may fight him, run away, or she may just huddle in a corner with her tail protected. If she doesn't raise her tail, the buck can't get to where he needs to be. Remove the doe and try again later. She will usually come around after a few attempts, or it may take a few days. If the buck isn't aggressive enough, try her with a different buck.
..... Get her in the mood. A reluctant doe can sometimes come around due to changes. Change her cage and neighbors. Put her next to a buck. Take her for a car ride. Or better yet, take her to a show. The excitement, new smells, and all those fine bucks has been known to turn a doe on.
..... Be careful! Both the buck and doe can become very excited. An intruder could be attacked and bitten. That would be you! If you fear for the safety of your hands when separating a pair, it's a good idea to put on a pair of gloves.
3. Timing. There are several factors that affect successful breeding.
..... How it works. Rabbits don't have a "season" like other mammals. They do seem to have a sort of "heat cycle" that comes around every 5 days or so. The doe may not be receptive outside this cycle. The actual act of copulation triggers the release of a doe's hormones and eggs. The 1st mating may not be enough to impregnant her as it takes time for the eggs and sperm to come together. Remove the doe after they have mated a few times. Then give her back to him after an hour or so. This is said to increase the odds that she will take, and maybe increase the size of the litter.
..... Age. Netherlands can become sexually mature fairly young. Sometimes as young as 4 months. They are considered adult at 6 months. Breeding age varies with the rabbits and often within particular lines. For instance, my BEW does often conceive at 4 1/2 - 5 months, where my shaded and himis might not until well over 8 months or even 1 year. I usually breed a doe the 1st time when she is about 6 months. Bucks are usually mature by 5-6 months. A buck can perform well into his later years, but most does should be retired after 3-4 years. They usually won't produce much after that, and it can be very hard on them.
..... Condition. The rabbits should be in good condition. Not too fat. A pudgy buck might not be able to get past his spare tire. A fat doe will have a hard time getting pregnant and kindling. I like to keep my brood does on the boney side. Not skinny, but where I can feel their hip bones. Too much fat on a doe accumulates around her ovaries, and that can hinder conception. The molt which usually happens during summer heat waves is not a good time to breed. The bunnies will be stressed and out of healthy condition for breeding. It's said that bucks will become sterile during long periods of summer heat. I usually lay off breeding for the hottest months while they are molting.
..... How often. It's said to keep does in breeding condition, you should keep them "barefoot & pregnant". Allowing a doe to go for too long between litters can affect how easily she conceives or kindles the next time. I like to rebreed a doe when her litter is 4-6 wks old. This depends on her condition. If she is in terrible condition, I will wait until she recovers more. If she is good, she can be rebred earlier. A buck can cover more than one doe in one day, but I prefer to let him rest until the next day before I give him another doe. If a doe has produced several litters in late winter and spring, I let her rest through the heat of summer.
..... Seasonal. In nature, rabbits' normal breeding season is spring. The days are getting longer and warmer, and food is abundant. Breeders generally have the most success in spring. In winter, some breeders fake it by increasing daylight with artifcial lighting. Lots of natural light in the rabbitry can help,too. Fall through winter is most often frustrating for getting litters.
..... By the moon. Ok, this is a bit of stretch, but it's said that breeding on the full moon will produce more does. I have found this to be true! Whether truly due to the full moon, or just dumb luck is hard to say. I am blessed with plenty of does by breeding on or closely around the full moon, so that's what I do. It's said that breeding near the new moon will produce more bucks.
..... You decide when. As a rule, rabbit gestation is about 31 days. This can vary a day or so either way, but you can often count on 31 days. If you want a litter born on your birthday, Christmas, etc, you can do that. Count back to find a breeding date. This method of picking kindling dates is called "Breed Back Schedule". I try to avoid having a litter due on a show weekend, or other reason I can't be here for a couple days. I like to be here for the big event.
4. Records. Write down when the pair was bred. A calendar and notepad in the rabbitry are real handy. Note the day of breeding, and then count 31 days to note the day of expected birth. Don't forget to note who was bred to who on that day. Some breeders hang a tag on a doe's cage with this info. I keep a breeding record for each doe. It's a history of each breeding, litter, and failures, so I can keep track of how that doe produces, and a quick reference for offspring's ages and parentage. Since the bucks are included in this record, I have a handy reference for them as well.
5. Wait. If all goes well, in 31 days you should be blessed with a fine litter.
