milk, 1 : 3, 1.7 lbs., at a cost of 3.64 cts. ; on the grain and clover or grass 

 ad libitum, 1.38 lbs., at a cost of 4.05 cts. ; and on the grain and tankage 8 : 1, 

 1.55 lbs., at a cost of 4.51 cts. per pound. 



In the fifth experiment 9 pigs were divided into 3 lots and fed for 72 days 

 to compare a full grain ration of barley and oats 4 : 1 in pens and on pasture 

 with a one-half grain ration and pasture. On the full ration and pasture the 

 average daily gain per head was 1.37 lbs., at a cost of 4.24 cts. per pound; on 

 the half ration and pasture, 1.03 lbs., at a cost of 2.82 cts. ; and with the full 

 ration in pens, 1.57 lbs., at a cost of 3.96 cts. per pound. 



In experiment 6, 9 Poland-China pigs, 10 to 12 weeks old and averaging about 

 40 lbs. each, were fed for 28 days on a mixed grain ration consisting of 2 parts 

 peas, 2 parts barley, 1 part oats, and 3 lbs. of skim milk to i lb. grain. The 

 average daily gain was 0.92 lb. per day, at a cost of 3.62 cts. per pound. In 

 the next experiment the same pigs were fed for 44 days a basal ration of bar- 

 ley and oats 4 : 1. Lot 1 received sugar beets in ^addition and made a daily 

 average gain per head of 1.1 lbs., at a cost of 3.86 cts. per pound. Lot 2, fed 

 the grain and skim milk 2 : 1, made corresponding gain of 1.69 lbs. at a cost 

 of 4.2 cts. per pound. Lot 3, fed the grain and tankage 8 : 1, gained 1.3 lbs. at 

 a cost of 4.65 cts. per pound. 



In experiment 8 there were 4 lots of 3 pigs each and fed for 65 days. Lot 

 •1, receiving equal parts of barley, wheat, and oats made a daily average gain 

 per head of 1.3 lbs., at a cost of 5.02 cts. per pound. Lot 2, fed the grain and 

 skim milk 1 : 3, gained 2.1 lbs., at a cost of 4.62 cts. per pound. Lot 3, fed 

 the grain and sugar beets ab libitum, gained 1.83 lbs. at a cost of 4.45 cts. per 

 pound. Lot 4, fed grain and clover hay ab libitum, gained 1.7 lbs. at a cost 

 of 4.58 cts. per pound. 



A summary of results of these and the previous experiments is given. 

 " For conditions in Montana the value of the supplemental food is : First, 

 skim milk; second, roots; third, tankage: fourth, pasture; fifth, clover and 

 alfalfa. . . . Peas make a more efficient hog feed than does barley, but because 

 of the greater cost of the peas the barley makes a more economical ration." 



Some poultry experiments, T. I. Mairs {Peniisylvania 8ta. Bui. 87. pp. 

 3-.'iS, figs. 13). — In the poultry experiments of '1906 the points luider observation 

 were rate of growth, food consumed, weight at different ages, relative weight 

 of pullets and cockerels, and the loss in dressing and drawing. The chicks 

 were fed corn and wheat in equal parts and a mash consisting of 50 lbs. corn 

 meal, 25 lbs. wheat bran, 15 lbs. gluten feed, 5 lbs. oil meal, H lbs. alfalfa 

 meal, and 13 lbs. animal meal.
