Offal

In Mary's butcher shop, you can also find an offal shop.

The adjutant bird (Leptoptilus dubius) is one of Nature’s little jokes. It is a caricature of a bird, a mixture of gravity and clownishness. Everything about it is calculated to excite mirth—its weird figure, its great beak, its long, thin legs, its conspicuous pouch, its bald head, and every attitude it strikes. The adjutant bird is a stork which has acquired the habits of the vulture. Forsaking to a large extent frogs and such-like delicacies, which constitute the normal diet of its kind, it lives chiefly upon offal.

1817, John Taylor, Arator; Being a Series of Agricultural Essays Practical and Political in Sixty-One Numbers, Baltimore: John M. Carter, No. 32, Indian Corn, p. 96, https://books.google.ca/books?id=paMBAAAAYAAJ&printsec=frontcover#v=onepage&q&f=false The whole of the corn offal is better food than wheat straw, but its blades and tops are so greatly superiour, that cattle prefer them to hay, and will fatten on them as well.

Our standard wheat flour contains only the endosperm and represents practically a 75 per cent. extraction. The remaining 25 per cent. is known in the trade as grain offal or mill-feed, and is used largely as a concentrated food for live stock, being prized in the feeding of dairy cattle.

[…] the fragments are broken down and the finer particles are collected by sieving; finally, there is the bolting of the assembled fine fractions, with exclusion of the wheat offal which includes bran and a number of other commercial fractions like red dog and shorts.
