If so, what else? From Aviation Herald;
"A Singapore Airlines Boeing 747-400 freighter, registration 9V-SFI performing flight SQ-7108 from Adelaide,SA (Australia) to Kuala Lumpur (Malaysia) with 4 crew and a cargo of 2,186 sheep, was enroute at FL320 about 400nm south of Denpasar (Indonesia) when the crew received a smoke indication in a cargo bay, descended the aircraft to FL250 and diverted to Bali Denpasar for a safe landing about 45 minutes later. Emergency services did not find any trace of fire, heat or smoke.
The smoke indication was identified to be the result of exhaust gasses and manure produced by the sheep.
The aircraft was able to depart again after about 2.5 hours on the ground in Denpasar and reached Kuala Lumpur about 2.5 hours later."
