The only pigs thai showed better results in pens than on pasture 
were those on grain and milk. Those receiving grain alone on pas- 
ture gave very much Larger gains, required Less feed per LOO pounds 
gain, and ate more feed than those receiving grain alone in pens. 
Linfield suggests that i ither bhe exercise or the feed obtained by the 
run on pasture gave these pigs greater appetite ami enabled them to 
digest a greater amount of iced daily. The fact that neither of
