﻿THE COMMERCIAL FATTENING OF POULTRY. 3 



compare favorably with the results at the other stations. The cheap- 

 est gains were made on short-fed lots, but many of the lots could have 

 been fed longer with profit if conditions had been good for fattening. 



A ration made up of equal parts, by weight, of corn meal and low- 

 grade wheat flour was fed from the commencement of the season, 

 July 23, until August 11, when shorts were added, making equal 

 parts of corn meal, flour, and shorts up to September 7, at which 

 time the ration was changed to 3 parts corn meal and 2 parts flour, 

 which was fed to the end of the season. All of these rations were 

 mixed with condensed buttermilk, diluted with one part of water, 

 making a thick feed. It may here be stated that whenever "parts" 

 are mentioned in connection with a ration, it means parts by weight, 

 and "flour-" always means low-grade wheat flour. 



Each of the above rations produced good results, and no apparent 

 change in gains occurred which could be attributed to the feed when 

 the ration was changed. The heat at this station was at times very 

 intense, which may have made the ration containing shorts prefer- 

 able to the regular ration of 3 parts of corn meal and 2 parts of flour, 

 but the results compared with those at Station 2 (Experiment D) do 

 not indicate that there was any advantage in adding a large propor- 

 tion of shorts to this feed, provided thick condensed buttermilk was 

 used. Later in the season good results were secured on a ration of 3 

 parts of corn meal and 2 parts of low-grade flour without any shorts. 



In this experiment the average cost of producing flesh was greater 

 with broilers than with roasters, which was due to the unfavorable 

 conditions in the house, particularly to the extreme heat in the first 

 part of the season and to overcrowding later.
