HOGS 



During the year a careful record was maintained of the hogs 

 at the University Farm and valuable information secured regarding 

 the effect of feeding certain foods to growing and fattening hogs. 



fattening iior.s on garbage alone 



Eight pigs in ordinary field condition, weighing a total of 605 

 pounds, were fed over a period of 25 days on garbage alone. At 

 the outset the pigs seemed to relish the feed, and ate it greedily. 

 All animals did well, making rapid and uniform gains. At the end 

 of 25 days the pigs weighed 981 pounds, making a total gain of 376 

 pounds. This gain at 16 cents a pound, which was the local price 

 at that time, would amount to $60.16 for the gain in live weight. 

 The following statement gives the results of this test : 



Average weight at beginning, 75.6 pounds. 



Average weight at end of 25 days. 122.6 pounds. 



Average gain per pig, 47.0 pounds. 



Average gain per pig per day, 1.88 pounds. 



TWO METHODS OF RAISING REGISTERED DUROC-JERSEY GILTS 



Five gilts, born January 10. 1918. have been under observation 

 lor a period of 284 days. They were weaned when about eight 

 weeks old, and weighed approximately 35 pounds each. All five 

 animals were from the same litter and uniform in size, vigor, and 

 quality. Two of them were sold April 6. 1918. and raised in the 

 ordinarv manner used in the district. The other three received 

 good care and attention, being fed on rolled barley and corn bran 

 until July 15 w^hen they were given rolled barley; after this date 

 they were fed on garbage. The weights of these animals on Octo- 

 ber 21, 1918. when the pigs were 284 days old. are given in Table X. 



TABLE X. — WEIGHTS OF PIGS RAISED ACCORDING TO TWO METHODS 



It is interesting to note that the two gilts on Farm A weighed 

 a total of 250 pounds, which is 40 pounds less than the lightest gilt 

 raised on Farm B. The average weight of a giU raised on Farm 

 A was 125 pounds, while the average weight of gilts raised on
