Perhaps they could give them hing or asafoetida which Indians from India place in their food to keep you from farting. Hing smells really bad, but when you cook it with your meal it stops smelling and tastes like onion or garlic. And it keeps you from farting!
Methane from belching cattle can be reduced, researchers say

TOKYO - Researchers have stumbled on a way to stop cattle from emitting methane, a potent greenhouse gas, when they belch, a finding that could help the fight against global warming.
Methane generated when livestock belch while eating is said to account for 5 percent of global greenhouse-gas emissions. Supplementing the animals' diet with cysteine, an amino acid, and nitrate can reduce the methane produced by the animals, researchers say.
Methane is generated in the stomachs of ruminants, such as cattle and sheep, as bacteria break down plant fibers. The gas is emitted into the atmosphere when the animals belch as they chew cud.
The team at Obihiro University of Agriculture and Veterinary Medicine in Hokkaido said that the nitrate does not affect milk quality and the amount of cysteine a cow needs each day costs about 95 cents.
