From Out-Door Sports in Scotland by "Ellangowan" (pseud. of James Glass Bertram) (London: W. H. Allen & Co., 1890), page 187 & 332:

No poacher is so stupid as to send "cheepers" or "piners" to his merchant. ...

These men bought from keepers, through the agency of a confederate who shared in the profits of the swindle, all the poor grouse which could be obtained—"cheepers," "piners," and "cripples" especially. ...

...these men opened all the hampers of grouse sent by the same train, and, selecting the largest and fattest birds, replaced them with "piners" or "cheepers." ...

It is better to have a hundred birds in fine condition and of heavy weight, than two hundred half-hungered "piners."

From Veterinary Journal and Annals of Comparative Pathology, Volume 40 1895:

In Germany they allowed the meat of the "piner" or "waster" to be sold....

Some animals seemed to resist the disease [tuberculosis], but others to succumb to it. The byre was a ricketty old place with sanitary arrangements altogether bad, and the marvel was that any of the animals escaped at all. There were only one or two of what might be called "piners;" the others seemed to hang on and to be fairly well.

From Bulletins of the Aberdeen and North of Scotland College of Agriculture, 1903-4

The experiments do not lend any support to the idea that feeding on separated milk and substitutes so weakens the constitution of the calves that they are likely to become piners, or to succumb to disease. All the lots suffered from minor ailments like colds, and the whole milk calves were just as much troubled in this respect as the others. Three calves went wrong after weaning, and had to be removed from the experiment. Two of these, which became piners, and succumbed to tuberculosis, were whole milk calves.

From The Bankers' Magazine, Volume 67 London, 1899.

The question was raised as to whether there should be a limit of price under which no animal should be insured, so as to exclude "piners" from the operation of the insurance system.
