100 lbs. The results for each pig are given in tabular form. The gain 

 made by the Tarn worth -Dnroc pigs cost 4.58 cts., the Poland-Chinas 

 3.78 cts., the Tam worths 3.63 cts., the Tarn worth-Poland Chinas 3.72 cts., 

 and the Berkshires 3.60 cts. per pound. The sows generally lost weight 

 while they remained with the pigs. 



The second test was made in the winter of 1894-95 with 5 lots of 

 pigs made up as follows: Lot 1, 7 Poland-Chinas; lot 2, 10 Tamworths; 

 lot 3, 8 Yorkshires; lot 4, 8 Tam worth-Poland-Chinas, and lot 5, 6 

 Tamworth-Durocs. Five and six pigs were dropped from lots 1 and 2, 

 respectively, before the end of the test, and 2 pigs each from lots 3 

 and 5. The trial lasted from 56 to 224 days. The pigs were fed under 

 the same general conditions as in the iirst test. The results for each 

 pig are expressed in full in tabular form. The average cost per pound of 

 gain for the Poland-Chinas was 4.22 cts. and for the Tamworths 3.95 cts. 



"For the first four weeks, while fed with the sow the Yorkshire pigs made the 

 most economical growth and the Tamworth the most costly. The Tamworth sow, 

 however, gave very little milk and the pigs wore at mnch disadvantage for some 

 weeks on this account. For the first month after removal of the sow the Tamworth 

 pig made growth at the same cost as the Yorkshire, and more rapidly." 



The third test, which lasted 224 days, was made with 4 lots of pigs, 

 as follows: Lot 1, 6 Poland-Chinas; lot 2, 3 Tamworths; lot 3, 9 York- 

 shires, and lot 4, 4 Tamworth-Durocs. Two, one, and five pigs were 

 dropped from lots 1, 2, and 3, respectively, before the close of the test. 

 The pigs were fed under the same general conditions as in the first 

 test. The results are expressed in full in tabular form. The average 

 cost per pound of gain for the Poland-Chinas was 3.44 cts., for the 

 Yorkshires 3.34 cts., for the Tamworths 3.81 cts., and for the Tamworth- 

 Durocs 3.39 cts. The total gain made by the Tamworths was about 

 222 lbs., the Tamworth-Durocs about 209 lbs., the Poland-Chinas about 

 192 lbs., and the Yorkshires 158 lbs. 



"The cost of growth of pigs during the first month while fed with the sow was 

 least with the Yorkshires, as in the former trial, and highest with the Tamworths. 

 The growth for the first month or so after removal from the sow was at least cost 

 with the Poland-China pigs."
