Same tricks every Eid, and every Eid somebody pays for weight that walks off overnight.
- Salt and water. Heavy salt, then all the water it wants, just before sale. Looks full, feels tight and sloshy, and is a smaller animal by morning.
- Spray paint. White patches to imitate a premium breed. The colour sits too evenly and goes wrong at the edges of the hair.
- Teeth, filed or simply misrepresented.
- A gutful of feed on the morning of sale.
- A hidden limp, covered by keeping the animal standing still or walking it only on soft ground.
- A borrowed animal stood alongside to make the one for sale look like part of a good lot.
