The second set of tables give the records of feeding trials of pigs 

 for some weeks during the cold weather in the fall and early winter 

 months. The pigs were Poland China, Tamworth, Yorkshire, Tam- 

 worth-Poland China cross and Tamworth-Duroc cross. Some of the 

 Tamworth and Poland China pigs were also fed through the winter, 

 and, considering the unusually cold weather of the winter, 

 1894-'95, compared favorably with the pigs fed during the summer. 

 The Tamworths seemed better able to endure the cold weather how- 

 ■ever. The pens although dry and sheltered were very cold. The 

 food cost of all grain for the whole winter was for the Poland China 

 pigs 4.22 cents per pound and for the Tamworths 3.95 cents. 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 were at much 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 cost of growth made in the same periods by each of the other 

 lots of pigs will be found in the tables. 



The av^erage weight per pig at birth was for the Poland China- 

 3.1 pounds; Tamworth-Poland China cross, 2.7 pounds; Tamworths 

 Duroc cross, 2.4 pounds ; Tamworth, 2.3 pounds ; Yorkshire, 1.9 

 pounds. The average weights at different periods of feeding are 

 shown in the tables.
