A Montana man trying to illegally create a 'giant sheep hybrid' went on a hunt for sheep parts and testicles, the authorities say

• An 80-year-old rancher was part of a 10-year conspiracy to cross-breed huge sheep for hunting, US officials said.
• Officials said Arthur Schubarth cloned a prized Central Asian argali sheep and sold its hybrid offspring.
• These huge sheep, sold for up to $10,000 each, fetched higher prices in the game market.

A Montana rancher, who pleaded guilty to two wildlife-related felonies, tried to illegally breed a "giant hybrid sheep" species for higher returns in the hunting market, the Justice Department said.
