Number of fall offs in relation to sex ratio

[Whipple]

So I was wondering, does anyone keep track of what that sex ratio of their litters are? Think it has anything to do with number of fall offs?

No, because usually only let the buck falloff once and the ratio seems to do more with the buck or doe than anything. Some doe/bucks seem to have more does, and some more bucks.

Makes me think of my brothers. Brother/wife --two boys, next brother/wife--two girls, next brother wife--two boys.

This is a very interesting subject i've been thinking about regularly.

My bew doe had 3x litters of 5 with 1 to 4 ratio.
1st litter of 5, 1 buck and 4 doe's. (he was running free and she had escaped, so idk how many times he got her)
2nd litter of 5, 1 doe and 4 bucks. (just 1 fall off)
3rd litter of 5, 1 buck and 4 doe's. (9/11 fall offs)

I have no idea what this means..

I know in humans you can affect the chances of getting boy/girl by changing the frequency at which you try. This is because one gender of sperm (forgot which, male I think) does faster than the other, but also swim faster. Trying on a daily basis means you have more of the fast-swimmers, whereas waiting a day or two between trys will decrease the amount of them because they've died off within the prostate.

I heard similar things and i believe someone posted it here or on another forum.
But that had more to do with increasing litter sizes by multiple breedings.

The female sperm is heavier than the males, so they are indeed slower (my biology teacher told this recently too).
So the males reach the eggs faster, but by the time the female ovulates and releases her eggs, some of the males die so the females eggs arrive just in time without waiting and the possible risk of dying.

I'm sure someone else will be able to point this out better than me.

I have never though about this, I put a doe with the buck,an allow him to mount and fall off as many times as he wants.
I watch to make sure he is able to do his business. I usally keep them together for 30 mins. less if the buck shows no intrest after a couple of times.
I have 1 buck, he is all about business, 2 or 3 times and he is finished, and pays no more attention to the doe.

Most of my does won't let the buck mount more than 2-3 times. After letting the buck mount once, and having litters of 10+, I stopped waiting. Five minutes is all they get, I have too many rabbits any other things to do. 30 minutes is my entire rabbit chore time.
