ANIMAL PRODUCTION. 601 



2 reciuired 7. 1 11 )S. of sugar-beet pulp and 3.46 lbs. wheat and barley mixture, while 

 lots recjuired ;x76 lbs. of sugar beets and 4 lbs. of the same grain. In lot 1 the 

 dressed weight was 77 per cent of the live weight. In the case of lots 2 and 3, it wa'^ 

 80 i^er cent and in case of lots 4 and 5 it was 84 per cent. Rating pork at 6 cts. per 

 pound there was a loss of $1.04 and 71 cts. in lots 1 and 3, and a profit of |;1.50, 

 $1.75, and 96 cts., respectiveh', in lots 2, 4, and 5. Rating pork at 7 cts. per pound, 

 there was a i)rolit of 13 cts., $3.35, 95 cts., $3.90, and $2.93, in the 4 lots respectively. 



The second test was made with 9 Berkshire pigs divided into 3 lots of 3 each, aver- 

 aging about 150 lbs. in weight at the l)eginning of the trial. Lot 1 was fed alfalfa 

 hay, corn, and l)arley, consuming 0.49, 3.72, and 1.72 lbs. j)er pound of gain, respect- 

 ively. Lot 2 was fed corn and barley, the amounts required per pound of gain being 

 3.63 and 1.65 lbs. Lot 3 was fed corn, barley, and sugar beets, requiring 3.64, 1.91, 

 and 1.03 lbs. per i)ound of gain. In the 95 days of the test the average daily gain 

 per pig in the 3 lots was 1.13, 1.08, and 0.99 lbs., and the cost of a pound of gain 4.9, 

 4.6, and 5.2 cts. The calculated profit, rating jiork at 5 cts. per ])Ound, was $1.73, 

 $1.94, and $1.26. The dressed weight of the j.igs in lot 1 averaged 86.1 per cent of 

 the live weight. The values for the other 2 lots were very similar, being 87.4 per cent 

 for lot 2 and 87.1 i)er cent for lot 3. 



The third test reported was made with 4 lots of Berkshire pigs, lot 2 containing 2 

 animals and the other lots 3, the average weight at the beginning of tke trial for the 

 4 lots being 164.5, 104, 112.5, and 98 lbs., respectively. In the 69 days covered by 

 the test the pigs in lot 1 made an average daily gain of 0.98 lb. on a ration of corn 

 only, consuming 6.43 lbs. per pound of gain. In the case of lot 2 the gain was 1.11, 

 the food eaten per pound of gain being 3.08 lbs. corn and 3.01 lbs. shorts. In the 

 case of lot 3, the average daily gain was 1.31 lbs., the food required per pound of 

 gain Ijeing 2.61 lbs. of shorts, 0.88 lb. wheat, 0.85 lb. oats, and 0.87 lb. barley, the 

 grains being so rotated that shorts were fed with wheat and oats on 1 day, with 

 wheat and barley the next, and with oats and barley the next. With lot 4 the aver- 

 age daily gain was 1.27 lbs. and the food eaten per pound of gain, 2.43 lbs. corn, 0.84 

 lb. wheat, 0.80 lb. oats, and 0.80 lb. barley, the corn V)eing rotated with the other 

 grains, as in lot 3. The average cost of a pound of gain in the 4 lots was 5.3, 4.8, 4.7, 

 and 4.7 cts., respectively, and the total profit per lot, rating pork at 5 cts. a pound, 

 $1.41, $1.18, $0.69, and $1.19. The dressed weight in the 4 lots was 78.6, 77.4, 81.6, 

 and 79.2 per cent of the live weight, respectively. 



The princi{)a] deductions drawn from the.se tests as a whole follow: 



"Home-grown grains fed in proper proportion to balance the ration are more valu- 

 able than corn. 



"A well balanced ration gives better returns in every case than a poorly l>alanceil 

 ration, and a mixture of grains is better than a single grain fed alone. 



"Sugar beets for swine feeding were unprofitable with us, either fed alone or in 

 combination with grain. Green pasture would probably serve the purpose of fur- 

 nishing succulent food for growing pigs at less expense. 



"Sugar beets are little more than a maintenance ration when fed alone to hogs. 



"Sugar beets and sugar-beet pulp proved equally valuable in our experiments, 

 and because of its cheapness and effect on growth we believe pulp may be profit- 

 able to feed to growing pigs in connection with a grain ration, or during the first 

 part of a fattening period. 



"These experiments indicate that sugar beets may have a value of about $1.50 

 per ton when fed to hogs in combination with grain. Beet pulp gave a return of 

 $1.50 per ton when fed in combination with grain. 



"Sugar-beet pulp served the same purpose in our hog rations as did sugar beets 

 and at less expense. It was necessary to mix beet pulp with grain in order to 

 educate the pigs to eat it. We would not recommend feeding more than 2 lbs. of 

 pulp to 1 lb. of grain in a ration for pigs which are from 100 to 200 lbs. in weight.
