 in conjunction with meal and milk. The average daily gain 

 was rather larger in the case of mangolds, but more mangolds 

 were eaten per day. The result of the test may be given

Carrots. — In 1892-94 experiments were conducted on nine 

 different farms in Canada, and Henry states (p. 596) that 

 carrots and mangolds containing equal quantities of dry 

 matter had similar values for pigs. It is stated that in some 

 instances carrots have returned 305. per ton by being con- 

 verted into pork.* 



Boiled Potatoes. — In Henry's Wisconsin experiments 

 boiled potatoes with maize meal were compared with maize 

 meal alone, and it was found that 441 lb. of potatoes effected 

 a saving of or produced the same gain as 100 lb. of maize meal. 



Fjord's Danish experiments showed that 400 lb. of potatoes 

 were about equal to 100 lb. of grain. 



Clover and Lucerne. — Pigs cannot profitably be fed on a 

 diet of green clover or lucerne only ; when confined to or fed 

 mainly on green forage they are liable to lose weight. Clover 

 and lucerne have been found in America to be of great value 

 as supplemental foods for pigs, and, compiling a table from 

 the figures given by scientific observers, Coburn found that 

 in America an acre of lucerne is worth for growing swine as 

 much as six acres of average wheat, more than four acres of 

 good oats, or if acres of good clover. 



These figures do not hold true for Great Britain, but it 

 may be said that, as shown in the table on p. 831, an acre 

 of good clover is equal to nearly three acres of average wheat, 

 and an acre of lucerne or rape to over 3J acres of wheat.
