Jw. Coates et al., GASTRIC-ULCERATION AND SUSPECTED VITAMIN-A TOXICOSIS IN GROWER PIGS FED FISH SILAGE, Canadian veterinary journal, 39(3), 1998, pp. 167-170
In 3 feeding trials, gastric ulceration was diagnosed in 2 of 12 lame
and recumbent grower pigs fed a diet of 50% fish silage produced from
the offal of farmed Atlantic salmon. Premature femoral physeal closure
and elevated serum retinyl palmitate levels, features of vitamin A to
xicosis, were also observed.
