Aseel from India/Pakistan is the ancestor of the Cornish breed(not to be confused of the ConishX), I have yet seen this cross used as meat cross in the USA the closest I have seen is for the Japanese Shamo crossed with BR, RIR and Leghorn in Hawaii in 1937, the Aseel is somewhat heavier than the Shamo but both have the same Asiatic game completion(broad shoulders and breasts). I plan to use an Aseel rooster over some Cornishx and Red Ranger hens
Here are some pics of the research with Japanese Shamo: https://scholarspace.manoa.hawaii.edu/bitstream/10125/53841/CtahrpsAgExp81.pdf
Excerpt from the research "The Japanese Shamo Game birds have full, deep, broad breasts, indicating good meat-carrying capacity, an important factor in producing quality market poultry."
Some pics: The Hybrid on the left always for example the Shamo/BR hybrid is on the left, pure BR on the right next to it.
