Question: Hi I have read with interest your information about Line Breeding and Inbreeding Co-Effifcients in your Breeding Barn. I have have a pretty Palomino Mare by Non Pro points winner Cardinal Spin out of a Bills Cutter/Tejano Chico Mare. What results would I get if I bred her to Lectric Playboy, Dual Jazz, Murrumbo Jasper or Who's Top Cat.
Allan Hunter

Answer: Hi Allan your Mare is 15.6% Doc Bar Line bred with Docs Spinifex, Freckles Playboy and Cutter Bill Bloodlines Close up. Her in breeding co-efficient is 0.5%.

Lectric Playboy is 14.1% Linebred Leo with Freckles Playboy, Jewel Leo Bars, Rey Jay and Sugar Bars close up in his pedigree his in-breeding co-efficient is 1.8%.

Dual Jazz is 25% line bred Doc Bar with Dual Pep, Peppy San Badger and Cutter Bill close up in his pedigree, In-breeding Co-efficient 3.6%.

Murrumbo Jasper is 12.5% Line Bred King with Cutter Bill, Big Red Chex, King Fritz and Royal King close up in his pedigree In-Breeding Co-efficient 1.3%.

Who's Top Cat is 21.9% Linbred Doc Bar and 18.8% Doc O'Lena. He has Freckles Playboy, Smart Little Lena and Jewel Leo Bars close up in his pedigree. His inbreeding co-efficient is 4.6%.

The resulting breeding with Lectric Playboy would give you a foal 31.3% Linebred Freckles Playboy and 15.6% Jewel Leo Bars inbreeding Co-Efficient 4.3%.

The Dual Jazz Cross would give you 20.6% Doc Bar and 12.5% Cutter Bill. Inbreeding Co-efficient 4%

Murrumbo Jasper would give you 37.5% Bills Cutter and 18.8% Cutter Bill and an inbreeding co-efficient of 7.2%.

Who's Top Cat would result with 18.8% Doc Bar and 18.8% Freckles Playboy. Inbreeding Co-efficient 4.3%

So I guess it comes down to your preference Freckles Playboy, Cutter Bill, Doc Bar or Bills Cutter.

The Dual Jazz cross gives you some extra Doc Bar whilst maintaining the Cutter Bill line. Lectric Playboy boosts the Freckles Playboy line, Murrumbo Jasper boosts the Cutter Bill line and the Who's Top Cat breeding gives you a little extra Doc Bar and Freckles Playboy.
