374 EXPEEIMENT STATION BECORD. 



Three sows fed 10 lbs. of kale per head daily for two months made a total 

 gain per sow of 5 lbs. Ten lbs. of kale per day proved a bare maintenance for 

 265-lb. sows. 



Two lots of 6 shoats each fed for two months, receiving kale and shorts and 

 beets and shorts, respectively, made average daily gains per head of 0.29 and 

 0.16 lb. The gains were too slow to be considered satisfactory in either case. 



Four lots of 4 pigs each fed for 60 days, lot 1 receiving chopped wheat and 

 skim milk ; lot 2, chopped wheat ; lot 3, chopped barley and skim milk ; and lot 

 4, chopped barley, made average daily gains per head of 1.95, 1.26, 1.91, and 

 1.59 lbs., respectively. The advantage of barley over wheat when fed alone was 

 20 per cent. The advantage of wheat over barley when fed with skim milk was 

 2 per cent. 



Two lots of 6 pigs each fed for 60 days on grain, shorts, and chopped barley, 

 lot 1 also receiving green alfalfa and lot 2 tankage, made average daily gains per 

 head of 1.06 and 1.55 lbs., respectively. In this test 100 lbs. of tankage were equal 

 to 30 lbs. of barley and 465 lbs. of green alfalfa. The lot on tankage showed 

 better appetite throughout the test and was in better market condition at the 

 close. 



In this experiment two lots of 6 pigs each were fed for 60 days, lot 1 receiving 

 wheat in a self-feeder and lot 2 being fed ground wheat in the usual manner. 

 Lot 1 gained 0.612 lb. per head per day and lot 2, 0.847 lb., requiring 6.3 and 5.42 

 lbs. of wheat per pound of gain, re.spectively. The ready-ground wheat showed 

 an advantage of 16 per cent in economy of gain and 37 per cent in rate of gain. 

 Following the test both lots were fed on ground wheat and made practically 

 the same gains. 



Two lots of pigs on second-growth vetch pasture, lot 1 receiving shorts, 

 barley, and skim milk and lot 2 shorts and barley, made average daily gains of 

 1.47 and 1.12 lbs., respectively. Lot 1 required 3.41 lbs. of grain and 6.57 lbs. 

 of milk per pound of grain, and lot 2 5.14 lbs. of grain. This experiment indi- 

 cated that second-growth vetch pasture during midsummer is not satisfactory 

 as a supplement for grain in pig feeding. 



Four lots of 7 or 8 pigs each fed for 62 days, lot 1 receiving i?horts and 

 ground wheat ; lot 2, wli^'at and milk ; lot 3, shorts and wheat : and lot 4, wheat 

 and milk, made average daily gains per head of 1.21. 1.64. 0.60, and 1.52 lbs. 

 for the respective lots, lot 1 requiring per pound of gain 1.45 lbs. of shorts and 

 2.90 lbs. of wheat; lot 2, 2.46 lbs. of wheat and 4.4 lbs. of milk; lot 3. 1.83 lbs. 

 of shorts and 3.41 lbs. of wheat; and lot 4, 2.5 lbs. of wheat and 3.94 lbs. of 

 milk. In this experiment lots 1 and 2 were crossbred and were very thrifty, 

 while lots 3 and 4 were scrubs and greatly lacking in uniformity. 



In a test to determine the cost of production two litters of crossbred Berk- 

 shire-Yorkshire pigs were used. It was estimated that the birth cost of each 

 pig was 29 lbs. of grain, 65 lbs. of skim milk, and ,V acre of pasture. •This 

 feed had a value of about 70 cts. After farrowing, the.'JO pigs were raised 

 almost altogether on milk and grain. From birth to Novombor 8, at which time 

 they weighed 104 lbs. each, it required per pound of gain 2.28 lbs. of skim 

 milk and 2..57 lbs. of grain, mostly shorts, this gain including the maintenance 

 of the sow while suckling. It is estimated that it cost 4.24 cts. per pound of 

 gain during this period, which, added to the birth cost, makes the total cost 

 for each pig at 100 lbs. .$4.94. These pigs were then divided into two lots, lot 1 

 receiving shorts and wheat and lot 2 skim milk and wheat. The cost per 

 pound of gain was 6.09 cts. for lot 1 and 4.54 cts. for lot 2. The total feed 

 cost of each 200-lb. finished pig fattened on shorts and wheat was .?11.03 and 

 for each pig fattened on skim milk and wheat $9.48.
