Yes. We agree on that. The creation of most breeds, cattle, pigs, horses, whatever, requires a breed goal and ruthless culling of those animals that deviate from this ideal.Every breed of every domesticated animal species is a human construct. Somebody had to select "unbreeded" animals to create a breed in the first place. Noah didn't have pairs of Mangalitsa, Berkshire, or any other "breed" of pig on his boat.
Sorry my point wasn't clear. But first, let me say I support your right to do anything you wish.I am not sure the point you are trying to make with these analogies. You have two examples of crossing disparate phenotypes (equine and bovine), but then describe the two pig breeds as having lots of common traits. How are these comparable? Breeding "like to like" reinforces phenotype. Cross-breeding is historically done to produce hybrid vigor, but has inconsistent results.
Look kid. I sure would like to buy you for the value of what you know, and sell you for the value of what you think you know. I'm sure the breeders that developed the plymouth rock would roll over in their graves knowing that their birds are crossed with Cornish, and the Cornish breeders likewise. I feel certain that the Asil breeders would have not approved of their birds being mixed with the Old English Games to create the Cornish, as they were mostly Islamic, and Asil means "pure" in their language, but here we are with billions of commercial broilers that are roughly 25% ancient heritage breed game chicken.I would suspect the breeders that spent their lives developing these distinct breeds would roll in their graves at the thoughts of such crosses. Enjoy.
A few common breeds come to mind, Large Black, AKA Large English Black crossed with long, lean Landrace.and BTW Haypoint, I’m not the OP but I am curious what purebred pig breed you would recommend as producing a good ratio of meat and fat? That is the purpose of the lean-lard cross.
