A.I best time

[Gosman_2]

I have been inseminating my gos for 4 days now,she will prob lay her 1st egg this year tonight ,I A.I her at 8pm tonight ,what i would like to know is how long after a gos lays can u leave it and still catch the next egg and will A.I just before 1st egg catch the 2nd?:confused:

[Tim Laycock]

The insemanations before she lays are the ones that will catch the next egg

[Hacker]

seems strange questions to ask if you are doing AI?

[Game & Pursuit Falcon UK]

you could be lucky and catch the second with what youve done. Realy you want to be inseminating at least after each egg, within two hours.

[Gosman_2]

thanks BB thats what i thought but have been told in the past to wait till after she layed ,i try to do both but my seamen suply is not that good at the moment

[Game & Pursuit Falcon UK]

If you wait until after the egg you generally find with any raptor that they draw better.

A.I with goshawks is relitvly knew to me ,though iv been sucsesful the finer points still alude me

[Tim Laycock]

After laying the Gos will be f****d and unwilling to accept an insemanation for a good few hours :yawinkle:

Get it in first m8 :yawinkle:

As u know BB she takes a while to get over laying before she ready to stand for insem but unlike most falcons who have a 48 hr cycle she is on a 3 day cycle so surly she has a longer receptive period after laying this is realy what i want to know

[Tim Laycock]

Not how I have understood it m8 but I am no expert :yawinkle:

[M & J Raptors]

As u know BB she takes a while to get over laying before she ready to stand for insem but unlike most falcons who have a 48 hr cycle she is on a 36 hr cycle so surly she has a longer receptive period after laying this is realy what i want to know

36 hours between egg laying times ?????

[Gosman_2]

sorry 72hr in between laying eggs :oops: :oops: [bit too much whisky]

[Hawkmaster]

So am I reading this correctly?
Even if you insemenate before the first egg you may only catch the 2nd or is that the 1st and 2nd?

BB, what period after she has laid do you give her the next one?

[As The Falcon Her Bells]

All this you could all easely find out trough some reading about how the egg develop and how long it takes to form a shell etc....
I find that the birds stand the best when they are most likely to fertilise a egg.
IE. a few hours before and up to 2 hours after laying, this is genarally after the first egg is laid as thats when the hormones starts surging.

I have read nick fox book on this subject but as i tried to say early on :oops: gosses lay 3 days apart but fox talks about falcons on a 2 day cycle:confused:

You need to be insemanating three days before the first egg to stand the best chance of catching it, My gos has layed like clockwork every three days but I could not get semen until she had layed the second egg, hence I have a 50/50 chance of having caught the third rgg and by my reckoning as I could not get a reliable supply of semen stand a 75% chance of having caught the fourth.

If you can feel an egg in her abdomen the day you first insemanate catching it is unlikley at best but stranger things have happened :shock:

You will probably find that she wont stand for half a day after laying the egg as she will be f****d so get in there a few hours before Paul :wink:

[Hawkmaster]

Cheers mate I will also feel for an egg in a while.
I insementated her last night and again this morning.
So here to hoping for the best.:wink:

[Tim Laycock]

If you insemanated from the same donation you would be better banging it all in at once Paul.

I know you want to spread it but she can keep it going better than you can hope to.

[Hawkmaster]

Yes I intended to do that but it was dark and the insementor thingy was on the wobble so thought I would rather wait till I could see properly.

Gave her another one today, I am told about four times what is needed, about 0.4cc, if that means anything to anyone?

[Goshawks00]

Insemination within 24 hours of egg laying will cover thge next egg. If you can feel the egg then it is to late to expect to fertlize that egg as the shell is already formed and the semen can not penetrate the shell.

Interessting! So what about on falcons? We find low fertility if we inseminate (fore AI) later then 2 hours of the egg being laid.
24 hours must just apply on gos?

[As The Falcon Her Bells]

I have read nick fox book on this subject but as i tried to say early on :oops: gosses lay 3 days apart but fox talks about falcons on a 2 day cycle:confused:

The avarage on my birds are 52-56 hours, but some has gone up to 70 hours in between the laying.
I always been told about the "2 hours after laying" rule, but I dont know if it apply on gosses?

Are gosses further between laying because egg develop slower or because egg start to develop later then in falcons?
To know the answer to your question we would have to find out about that?
(did that make any sense???)

[Gosman_2]

Well lucky 4 me the supply of seamen has increased so im able to inseminate before ,after and in between:D but if u had to buy each straw ,or like me the other day u had only a tiny amount ,knowing the best time to A.I becomes a very important question:roll:

[M & J Raptors]

It does not matter when you inseminate any bird, falcon or Gos, the bird will store semen much longer than you can in the fridge, last year we inseminated a Barbary Falcon, 1 hour after laying [forced], 6 days later she laid, the egg was fertile.

Look at natural pairs of gosses, they do not copulate just after egg laying, infact the female will sit on the egg for up to 12 hours. but they still fertilise eggs. all my imprint female gosses will not take semen just after laying.

cheers

Well we find that we get higher fertility (forced AI) when we can inseminate within a coupple of hours of egg laid then if she lay in evening and we have to wait all night untill we can go in (9 hours).
If you only have 4 eggs, 1st one an indicator egg, second one you inseminate to late, well then you really only have the chanse to get 2 fertile.

Hi Sarah

Yes with forced Ai you only have a small time window to catch the next egg,and its hard to catch the 2nd egg unless you get egg timing spot on, we have infra red cameras so we can see time of laying even through the night, but with standing females it does not matter when you inseminate, after all natural pairs do not wait for egg timings, and all we are doing is the same, putting semen into females.

sometimes with forced Ai we have been very lucky and caught 2 eggs with one insemination,

Yeah you are bang on, but it depends on the acsess of seemen tough.
A pair can copulate whenever they want to (god, some of them are at it every 10 minutes......lucky ********!!)
If we have a lot of female peregrines laying in the same time, (and we always try to use the seemen from the male who is most likely to produce white), we are happy if we can inseminate them 1 every or every second day, so then we try to prioroty the birds that we are most likely to catch an egg on at the time. I will stay up in the night waiting for my imprint to lay if I have been short of seemen, just to be on the safe side.....

Sounds familliar :!:
