424 Thirtieth Annual Report 



about 60 pounds of silage per head daily. Silage alone is not a 

 satisfactory ration to fatten thin range cows. 



The cows fed on a combination of silage and two pounds of 

 cottonseed meal made good gains and finished for marketing in 

 about 100 days. It is believed that this ration is a cheap and effi- 

 cient one for finishing cows for market. 



TWO METHODS OF RAISING GILTS. 



The five Duroc-Jersey gilts from the same littler have been 

 under inspection another year. These pigs were divided into two 

 groups consisting of two gilts maintained on one farm and three 

 on another. When they were 779 days old, or approximately 25^ 

 months, the two gilts raised on an ordinary farm weighed 175 and 

 222 pounds, respectively, while the three gilts maintained under 

 good conditions weighed 575 pounds, 610 pounds, and 630 pounds, 

 respectively. The number of pigs raised by the gilts from the two 

 different farms did not vary much. It may be that the pigs from 

 Farm B were too fat and those from Farm A were too thin for the 

 best results. It is planned to exchange two of these gilts from 

 one farm to the other and to study the development of the large 

 ones under inferior conditions and the small ones under good con- 

 ditions. 



FATTENING HOGS ON GARBAGE VS. ROLLED BARLEY. 



Eight hogs averaging 122.2 pounds live weight were divided 

 into two lots. Lot I was fed on garbage secured from the Univer- 

 sity Dining Hall and Lot II rolled barley from a self-feeder. The 

 pigs were fed over a period of four weeks. The garbage cost $25.00, 

 while the pigs fed on rolled barley were given $10.66 worth of feed. 

 These pigs ate an average of 19.04 pounds of rolled barley per day 

 and they weighed an average of 551.4 pounds during the feedmg 

 period, so that they consumed an average of 34.52 pounds of rolled 

 barley per thousand pounds live weight. 



The pigs in Lot I gained a total of 227 pounds during the four 

 weeks, while those fed on rolled barley gained only 97 pounds. The 

 average daily gain of the pigs fed on garbage was 2.03 pounds per 

 head, while those fed on rolled barley gained only .87 pounds daily. 

 Although the pigs fed on garbage were fed at considerably more 

 expense, yet they made much more rapid gains and cost only $10.73 

 per one hundred pounds increase in live weight, while those in Lot 

 II, fed rolled barley, cost $10.99. Hogs were selling on the local 

 market during the period while the test was being conducted at 16 

 cents per pound live weight. The profit secured from feeding the
