68 EXPEEIMEKT STATION RECORD. t Vol. 36 



Two lots of 240 lambs each were fed for 80 days, one lot receiving alfalfa and 

 the other lot alfalfa and oat sheaves 2 : 1. The average daily gains per head 

 were 0.021 and 0.024 lb. respectively, at a cost of 8.07 and 6.74 cts, per pound 

 of gain. 



Swine, E. S. Abchibald et al. (Canada Expt. Farm-9 Rpts. 1915, pp. 524-573, 

 pis. 4)- — Three lots of shotes were fed 70 days, as follows: Lot 1, shorts, oats, 

 and corn, 1:1:1, and skim milk, fed as slop ; lot 2, shorts, oats, corn, and skim 

 milk fed as slop, plus green rape; and lot 3, shorts, oats, and skim milk, plus 

 ground corn. The pigs made average daily gains per head of 1.5, 0.995, and 

 1.13 lbs., at a cost per pound of gain of 5.5, 6.2, and 5.9 cts., for the respective 

 lots. 



Five lots of pigs were fed 84 days, all lots receiving skim milk ; lot 1, corn, 

 shorts, and oil meal, 3:3:1; lot 2, corn, shorts, and tankage, 3:3:1; lot 3, 

 corn and tankage, 6:1; and lot 4, corn and tankage, 6:1; and lot 5, corn. 

 These pigs made average daily gains per head of 0.9, 0.9. 0.95. 0.43, and 0.^6 

 lb., at a cost per pound of gain of 3.06. 4.3. 3.5. 4.23. and 3.1 cts., for the 

 respective lots. 



Six lots of pigs were fed 42 days as follows : Lot 1, corn, shorts, and oil meal 

 1:1:1, and milk ; lot 2, the same grain ration, blackseed, and milk ; lot 3, black- 

 seed and milk ; lot 4, buckwheat screenings and milk ; lot 5, complete screenings, 

 flour, and milk ; and lot 6, blackseed and water. These pigs made average 

 daily gains per head of 1.05, 0.76, 0.14, 0.9. 0.48 and 0.01 lbs., at a cost per 

 pound of gain of 4.7, 3.8, 7.6, 2.7, 4 and 36 cts., for the re .spective lots. *' To 

 summarize the value of blackseed in this experiment it is safe to say that the 

 food value of this by-product is low even when fed in small quantities in a 

 well-balanced ration containing good variety ; that it has little food value when 

 fed alone or in conjunction with only one or two other feeding stuffs ; that ani- 

 mals of 160 lbs. weight can be made to eat 2 lbs. each per day and thus maintain 

 weight for a short period of about a month and a half; that this product is 

 rather unpalatable and, if constituting any considerable proportion of the grain 

 ration, is unpleasant to the animals. 



These lots were finished, all receiving for 42 days the same grain mixture, 

 with the following results : An average daily gain per head of 0.57, 0.88, 0.88, 

 0.83, 0.64, and 1.26 lbs., at a cost per pound of gain of 7.3, 5.7, 4.7, 5.6, 4.7, and 

 4.69 cts., for the respective lots. 



Three lots of sows were fed as follows : Lot 1, a regular grain mixture com- 

 posed of bran, shorts, and cracked corn, 1:1:1, fed as a thick slop ; lot 2, the 

 same meal mixture except that one-fifth by weight of this mixture was replaced 

 by tankage ; and lot 3, whole corn in a hopper grinder, together with shorts 

 and bran. In addition to the above grain ration all the sows received roots, 

 clover or alfalfa hay, and skim milk. The amount and cost of feed per sow 

 per day did not vary to any extent within the three lots except where tankage 

 entered into the ration, in which case the cost was higher, the increase being 

 proportionate to the amount of tankage used. The gain in weight of the sows 

 before farrowing and loss during the eight weeks immediately after farrowing 

 were fairly constant, with the smallest loss after farrowing in favor of the 

 tankage ration. The condition of the young pigs at birth was in favor of the 

 tankage ration. The average weight of pigs at birth was practically equal in 

 all lots, while the weights at four weeks and eight weeks of age showed a 

 slight increase in gain in each case in favor of the tankage ration. A compari- 

 son of lot 1, the check lot, with lot 3, where the grinder was used, showed only 

 a slight advantage in weight in the litters at all stages of growth. 



Four lots of 5 pigs each were fed 107 days as follows: Tx)t 1. barley chop; 

 lot 2, barley chop and feed flour, 3:1; lot 3, barley chop and shorts, 3:1; and
