Breeding Question

[TShelly]

Question: I tried a father x daughter cross this last time but the gyp didn't take. We bred the old man to 3 other gyps as well and none took. We are pretty sure he's just shooting blanks as he is almost 10.

So this time I will do a half brother-sister breeding. I'm trying to figure out how many times     the oldest sire will be in my pups.

CB was Blasters sire. Lexi is out of blaster x Fawn(outcross)

Briar is the result of an uncle x niece out of Blaster x girlfriend (she is out of Blasters littemate dot and an outcrossed male)

How many times will CB be in a Briar x Lexi cross??

[Bryant]

CB X 3 crosses. 

That cross will produce pups that are 31.25% CB

Was tryin to see what's the ups and downs of father to daughter breeding. I thought it would be some inbred pups with 10 toes lol.

[halfbreed]

if you like the father breed to the daughter then to the grandaughter

[halfbreed]

 oh yeah and then cut off any toes you don't need lol

[TShelly]

CB X 3 crosses. 

That cross will produce pups that are 31.25% CB

Thanks Bryant. How do you figure that out if you don't mind me asking. I hate having to ask everytIme I want to know %'s

In my understanding the father x daughter cross is the best way to recreate the father in your pups

I've been told by two guys with two separate lines that the grandfather x grand daughter seems to produce a big percentage of the TOP dogs. Now I'm not talking about good dogs but dogs that made the real good dogs look like amateurs.

My best dogs have come from first cousin breedings and the next best in my dogs has been aunt nephew and uncle niece breedings. I am now able to breed to dogs that go back to the Big Boy Blondie cross many times , but they have been bred by someone else with  other outcrosses and selection process for many years. You seem to get the hybred vigor without adding new blood or should I say, unknown blood. I have just started this and it has been eye opening.

TSHELLY,
This is an article I found a couple years ago. It explains it.

Determining the Percentage of Blood in a Pedigree    
You've probably seen the advertisements that tout "41% Poco Bueno" or "25% Leo." Have you ever wondered how they came up with those figures? It's not difficult to do. 
Percentage of blood simply adds up the approximate amount a particular ancestor might have contributed to your horse's genetic make-up. This is not an exact amount, however, as there are a lot of variables involved in breeding animals. (Watch for a future article about breeding terms such as homozygous versus heterozygous and in-breeding, line-breeding, and out-crossing.)
The pedigree below is for Alisa Lark, dam of Two-Time Superhorse, Rugged Lark. She is line-bred on three famous horses - Joe Reed, King, and Joe Hancock.
Parent   Grandparent   Great-grandparent   GG-grandparent   GGG-grandparent
Leolark   Lemac   Leo   Joe Reed II   Joe Reed
            Nellene
         Little Fanny   Joe Reed
            Fanny Ashwell
      Sorrel Sue   King   Zantanon
            Jabalina
         Tommy King mare   --
            --
   Tallalah   King Bob   Brown Bob   Snooper
            mare by Harmon Baker Jr
         Queen Ann   King
            Holland mare
      Daisy K   Copper   Tom Benear
            May Troutman
         Scar Face   Golden Bear (TB)
            Georgia
Aliso Gill 3   Pelican   Joe Hancock Jr   Joe Hancock   John Wilkens
            Brown Hancock mare
         Burnett mare   --
            --
      Covella (TB)   Coventry (TB)   *Negofol (TB)
            Sun Queen (TB)
         Sonora (TB)   *Light Brigade (TB)
            Ilma (TB)
   Snicker Girl   Snicker   John Gaston   Nowata Star
            Chouteau
         Fleet   Sappho
            --
      Okie Girl   Joe Tom   Joe Hancock
            TB mare
         Miss Tommy 99   Tom (Scooter)
            Riding type mare
Each parent contributing 50% of the genes that make up his or her offspring. For example, in the pedigree above Alisa Lark received 50% of her genes from her sire, Leolark, and 50% of her genes from her mother Aliso Gill 3. In turn, Leolark received 50% of his genes from his father, Lemac, and 50% of his genes from his mother, Tallalah. Continuing in this vein, Leolark received 25% of his genes from his paternal grandfather, Leo (Leo gave 50% of his genes to Lemac who in turn gave 50% of his genes to Leolark). Therefore Alisa Lark would have received 12.5% of her genes from Leo - 50% from Leolark, of which only 50% was from Lemac (25%), of which only 50% was from Leo (12.5%). However because of the way genes combine, this is only an approximation.
The chart below summarizes the percentages received from each ancestor in a given generation. Therefore, Leo, a great-grandparent, would have contributed 12.5% to Alisa Lark. For animals that show up more than once in a pedigree, you only need to add the percentages together. For example, Joe Reed shows up twice as a GGG-grandparent, therefore he supplied 3.125 plus 3.125%, or 6.25%. It's the same if the ancestor shows up in different generations. For example, King shows up as a GG-grandparent and as a GGG-grandparent, therefore he supplied 6.25 plus 3.125%, or 9.375%.
Parent   1 generation   50%
Grandparent   2 generation   25%
Great-grandparent   3 generation   12.5%
GG-grandparent   4 generation   6.25%
GGG-grandparent   5 generation   3.125%
GGGG-grandparent   6 generation   1.5625%
To help you figure the percentage of blood of a particular ancestor in your horse's pedigree use the chart and the steps below. Just remember that the percentage of blood is only an approximation of the inheritance a particular ancestor gave to your horse.
Step 1 - Determine the relationship between your horse and the targeted ancestor.
Step 2 - Find that relationship on the chart to determine the approximate percentage of blood that ancestor contributed to your horse.
Step 3 - If, as in many pedigrees, the targeted ancestor appears more than once in your horse's pedigree, repeat steps 1 and 2 for each occurrence and add the amounts together.
Another way to show where and how often an ancestor appears in your horse's pedigree is by listing the generation for each appearance. For example, in the pedigree listed above Joe Reed appears twice in the 5th generation. This would be written as 5 x 5. King appears once in the fourth generation and once in the fifth generation. This would be written as 4 x 5. If an ancestor appears more than twice, just list a generation number for each time that he appears. Larry Thornton calls this a "linebreeding pattern."
Percentage of blood can be used to help determine when two horses would be a good cross, but it is only one tool out of many. Beware of the breeder who uses it as the only tool. Just because two horses have a high percentage of a valuable ancestor doesn't mean they should be bred together, particularly if they have common faults.

CB X 3 crosses. 

That cross will produce pups that are 31.25% CB

Thanks Bryant. How do you figure that out if you don't mind me asking. I hate having to ask everytime I want to know %'s

Kind of hard to explain without seeing it, so I drew it out.  Basically each time the name appears in the ped, you add the corresponding percentage for that generation.  You get real drawn out, and it's best to let a computer do it.  That's how all those people with the FBMCBO dogs always say their dog is 27.46245% Ben and all that.  Hope this makes sense.

   Here is an inbreeding calculator. Just fill in the blanks. When done it will list all the blood percentages.
