Blue-grass and timothy versus clover and alfalfa. 



In Table XLVIII are given the results of an experiment 

 conducted at the Iowa Station ' in 1909 in which a pas- 

 ture of blue-grass and timothy was compared with alfalfa 

 in one case and clover in another. The pigs were of 

 spring farrow and weighed between 33 and 34 pounds 

 on June 4th when the test began. In addition to the 

 forage, the pigs of each lot were given a full feed of ear- 

 corn, supplemented during the last 39 days of the trial 

 by the addition of 10 per cent of meat-meal. The experi- 

 ment covered a period of 165 days, practically the entire 

 time from weaning to marketing.

Considering that straight corn was fed in all lots except 

 for the last 39 days, the gains made were exceptionally 

 good. The amount of pork credited to each acre of 

 forage would undoubtedly have been greater if a small

' Figured on the basis that 4 pounds of concentrates would 

 have been required for each pound of gain in dry lot feeding.
