Bloat in identical twin lactating cattle grazing clover-rich pastures was controlled by twice-daily drenching with 7 ml ‘ Pluronic’ L 64 in water. The drench did not alter milk composition and there was no significant difference in milk production between control and treated groups. A significant (P <0·05) linear relationship between bloat protection and butterfat production was found between twin sets. Drenching increased milk production in high-bloating cows but slightly depressed production in low-bloating animals.
