per pound of gain. The liogs fed on chopped barley and alfalfa hay seemed to 

 have keener appetites than did those which were fed sugar beets. It is thought 

 that the sugar-beet ration contained too much carbohydrates and not enough 

 protein. 



A lot of four hogs fed eight weeks rye and alfalfa hay made total gains during 

 the period of 79.5 lbs. per pig, consuming 3.89 lbs. of rye and 0.34 lb. of alfalfa 

 hay per pound of gain, while a similar lot receiving rye and steamed alfalfa hay 

 gained 88.25 lbs. per pig, consimiing 3.73 lbs. of rye and 0.31 lb. of steamed 

 alfalfa hay per pound of gain. The difference in favor of the steamed alfalfa 

 was deemed too slight to justify the .steaming process. 



Two lots of pigs fed eight weeks, lot 1 barley alone and lot 2 barley and alfalfa 

 hay, made total gains during the period of 71.71 and 91.43 lbs. per pig, lot 1 

 consuming 4.27 lbs. of barley and lot 2 3.73 lbs. of barley and 0.26 lb. of alfalfa 

 hay per pound of gain. From this test it is deemed quite evident that gi-ain 

 should be supplemented with other feeds. This experiment was carried on dur- 

 ing the winter months, and it is thought that still greater returns may be had 

 by feeding at the time of the year when the hogs may have access to alfalfa 

 pasture in connection with a full grain ration. 



Two lots of pigs were fed eight Aveeks as follows: Lot 1 barley and tankage 

 9:1, lot 2 barley and peas 7:3 (both rations containing practically the same 

 amount of protein). They made total gains for the period of 92.86 and 94 lbs. 

 per pig, lot 1 consuming 2.43 lbs. of barley and 0.37 lb. of tankage, and lot 2 2.21 

 lbs. of barley and 1.04 lbs. of peas per pound of gain. In a second similar experi- 

 ment, substituting wheat for barley, the lots made total gains for the period 

 of 75.98 and 83.85 lbs. per pig, lot 1 consuming 2.74 lbs. of wheat and 0.41 lb, 

 of tankage and lot 2 2.60 lbs. of wheat and 1.11 lbs. of peas per pound of gain. 



Four lots of eight pigs each fed five weeks, lots 1 and 2 by the self-feeder 

 method and lots 3 and 4 by the ordinary daily ration method, made total gains 

 during the period of 81.12 and 70.87 lbs. per pig, lot 1 consuming 3.94 Ibs^of grain 

 and lot 2, 4.02 lbs. per pound of gain. In a second experiment four lots of pigs 

 were fed eight weeks, lots 1 and 2 being self-fefl, lot 1 receiving bald barley and 

 lot 2 peas; and lots 3 and 4 receiving daily rations, lot 3 receiving barley and 

 lot 4 peas. They made total gains for the period of 05.96. 100.85, 8.3.72. and 84.86 

 lbs. per pig, lot 1 consuming 3.93 lbs. of barley, lot 2. 3.66 lbs. of peas, lot 3, 3.7 

 lbs. of barley, and lot 4, 3.69 lbs. of peas per pound of gain. 



In an experiment to determine the fee<ling value of ripe as compared with 

 green peas when hogged off in the field, two lots of 25 pigs each fed four weeks, 

 lot 1 on ripe peas and lot 2 on green peas, made total gains for the period of 

 30.4 and 38.4 lbs. per pig, lot 1 producing 380 lbs. of pork to the acre valued at 

 $26.60, and lot 2, 480 lbs. of pork, valued at $33.60. In a similar experiment in 

 hogging off field peas two lots of 18 pigs each were fed four weeks as follow,*; : 

 lot 1 Canadian field peas and kale, lot 2 pea5; alone. They made total gains for 

 the period of 50.23 and 45 lbs. per pig, lot 1 producing 452.07 lbs. of pork per aero 

 valued at $.36.17, and lot 2, 405 lbs. of pork per acre valued at $32.40. The results 

 of these two experiments would seem to indicate that green feed in connection 

 with grain rations is an important factor in fattening hogs. 



In an experiment to determine how to feed young growing pigs in order that 

 they may make their growth most economically, a lot of light hogs weighing ap- 

 proximately 78 lbs. each and a lot of comparatively heaAy hogs weighing 111 

 lbs. were fed on alfalfa pasture and a small grain ration. It was found that 

 on a ration of 3 lbs. of choppetl barley for each 100 lbs. of live weight the lighter 

 hogs produced the better returns. 



Eighteen pigs, averaging 66.67 lbs. in weight, on alfalfa pasture and a daily 

 ration of % lb. chopix;d barley i>er pig made a satisfactory growth, yet the gain
