WINTER FEEDING. 



In the winter feeding trial, eight pens were used, four pigs in each pen and eight 

 pigs on each ration. The breeds consisted of nine pure-bred Yorkshires, grade York- 

 shires and Yorkshire and Berkshire crosses. The ages ranged from six months to 

 three months. The pigs were sorted to get equal weights in each pen, and a pen of 

 large and one of small pigs were used in each trial, as it was impossible to get enough 

 pigs all the same age, breeding and size. They were confined in pens, eight feet 

 by nine feet, and not allowed outside. The pens were cleaned out every alternate 

 day and kept well bedded with cut straw. They were in an old well-lighted 

 building on a plank floor two feet above the ground. During cold weather they were 

 too cold, but at all times they had sufficient fresh air. The food was weighed to 

 thorn for each meal, and each pen got what it could eat up clean. The pens fed rice 

 meal grew a very heavy coat of hair and looked rough throughout. Several times the 

 pigs in these rice meal pens stiffened up and refused food, even when having less 

 food at the time than their neighbours. They had to be dosed with Epsom salts. 

 The other pens were always hungry and active throughout the trials. In contrast to 

 the summer trials each pig received only two and one-half pounds of skim milk 

 instead of fifteen pounds daily.
