F1, F2, F3 and upgrades

[bongkat]

Good day to all! I'm just new in this forum and I thank the moderator of this site for the approval of my membership. I'm interested in goat raising and I come across in some articles about these F1, F2, F3 and upgrades.  How does one differ from the other? Thanks in advance for your reply.

Well,in simple terms means percentages of blood.

if one breeds a purebred nubian sire (buck) to a native doe then the offspring will be a F1-50% nubian also considered an upgrade native.If you breed a purebred nubian sire to a F1 doe then the offspring would be a F2-75% nubian.Once you breed a purebred nubian sire to a F2 doe then the offspring would be a F3-approx.87% nubian and so on.

thats the long and short of it and can be done with any purebreed goat sire like boer,saanen,alpine,nubian etc.The sire or buck is always a purebred animal.

hope this helps

Thank you very much sir for your nice and concise explanation, now I know what is F1, F2 and F3 and so on.  Another question sir, can it be possible that the father buck can mate his own sire F1 doe? Or should it be another pure bred buck without any blood relation to the doe which can mate the F1 so their offspring can become F2?

To answer your question.First it is a bit of a double edged sword question but a good question.In breeding terms when one breeds a daughter back to her father or a son back to his mother this is called Backcrossing.Backcrossing is done for very specific reasons and with any form of in-breeding it comes with some risks,meaning,with any form of in-breeding only 2 things will happen,the offspring will be a very good goat or the offspring will turn out to be a very poor goat.Any form of in-breeding is a gamble but lets the breeder know 2 things,recessive or bad gene transfer,very poor goat or the transfer of good genes and a very good goat.But backcrossing is usually only done once as the bloodlines will be too close and cause problems for the offspring.

Linebreeding is much more common and is the breeding of half brothers and half sisters.The sire can be the same goat but the mothers are from different bloodlines.Line breeding also comes with some risks,one will end up with a good goat or poor goat.Poor results means you end that breeding program as this lets you know that only recessive genes are the dominate trait.

Every animal know to man has at some point in its life some form of in-breeding in its background.In truth thats how we have the quality animals we see today.

In truth proceed with caution and have a well planned and thought out breeding goal in mind before deciding any form of in-breeding.Like I said,when it works out right it works well but when it works out poorly it is a disaster.Line-breeding is used all the time to produce the quality animals that we all see in the show rings and future breeding stock.

hope this helps you.
