Bell & Evan Das Klassenbester Slow Growing Broilers

[nicalandia]

For anyone interested on the make of the Das Klassenbester(trade mark of Bell & Evans) They are using Aviagen's European Rowan Ranger "Classic Rangers" a Cross of regular sized New Hampshire type hens with good Egg laying traits and a Ross white CornishX Sire.

They sure did. Check this video State of the art 21st century Hatchery for their own brand:

Their Hatchery and Breeding Facilities are really high tech, they breed, hatch, feed and finish their own birds for their own label, that is a great strategy, the genetics is only a part of the equation. The females look very normal dual purpose type. The growth, type and meat is given mostly by the male

They live 7 weeks instead of 6. Still not what i would call a slow broiler!

To about 5 pounds.

it's "Slower" than pure CornishX, in Europe they grow them to 10 - 12 weeks here is the Ranger Classic http://eu.aviagen.com/assets/Tech_Center/Rowan_Range/RangerClassic-Broiler-PO-18-EN.pdf

It would be interesting to see how these birds compare with the standard Cornish-X. They sound like a great deal, 5.5 pound bird on 10 pounds of feed and maybe live a little better & healthier than the Cornish-X we get now. At my mile-high altitude, I would not get a standard meat bird.

We can make the comparison with Aviagen standard Ross 308 Broiler, 8 pounds at 7 weeks of age and about 13.5 pounds of feed

Their FCR are very close


Feed restricting a few CornisX females and crossing them with a Meatier RIR/BR or NH would yield something similar(perhaps not as efficient), one thing I have learn from all of these research that I have done one colored broilers is that the Oriental type(Big Wide Breast, thick bones) is clearly dominant over the European type and such a cross would produce a broiler type chicks

The 8 pound bird might not make it at my altitude. I will take a living bird @ 5.5 pounds over one that did not make it to 6 weeks here. Nice research!

Another Similar cross is the Hubbard JA757 "Slow"(Intermediate really) Growth broiler, which is a cross between Hubbard Red Dual Purpose hen(JA57 New Hampshire type) with a Standard CornishX Sire:

Using the Hubbard Broiler Calculator we can see the performance of this cross

The same Female when crossed with a New Hampshire Male performance:

Hubbard Broiler Calculator with standard dual purpose males like New Hampshire and RIR, but not every cross possible is available(I wanted to try a RIR male over a CornishX hen but the JA757 is as close as one could get)

J57Ki(the i stands for i+ non dominant white) dual purpose female(New Hampshire type) when crossed with a Egg Laying type RIR(like found on commercial red sex links) produces very poor performance(difference of 2.5 pounds between RIR and CornishX sires when using the same female type at the same 49 days of age)
