FOODS ANIMAL PRODUCTION. 



79 



Tables are given which show the food consumed and the gains made 

 by each pig- during each period, the difference between tlie live weight 

 and dressed weight, food consumed per pound of gain, and the profit 

 obtained. These data are summarized for the whole period in the fol- 

 lowing table : 



Summary of results of pbi-feedhuj experiment. 



IsTos. 1, 2, 7, and 8 were compared with Nos. 4 and 5 to determine the 

 relative value of concentrated and watery foods. ''The cost of food 

 for a pound of increase in live weight and the profits were slightly in 

 favor of the les.s watery ration. The shrinkages were identical by both 

 methods of feeding," 



Kos, 1, 2, 7, and 8 were compared with Nos. 9 and 10 to show the 

 relative value of skim milk and buttermilk. "The buttermilk had 

 about four-fifths the feeding value of skim milk." 



Nos. 1 and 4 (Poland-China) were compared with Nos. 2, 5, 8, and 10 

 (Berkshire) and Xos. 7 and I) (Yorkshire). "The Poland-Chinas and 

 Berksliires gave the same results. In another test Berkshires out- 

 stripped the Yorkshires," In each comparison the average live weight, 

 dressed weight, percentage of shrinkage, dry matter eaten per pound of 

 gain, live and dressed weight, cost of food per pound of gain in dressed 

 weight, and the total gain per pig are shown in tabular form. 



The author di.scusses the proper time to market pork, and calls 

 attention to the fact that after a time it costs more to keej) pigs than 

 the gain is worth. lie computes that the fertilizing value of the food 

 eaten was $38.93, or 02 i)er cent of the market value of the food, pro- 

 vided the manure was properly handled. 



Report on feeding experiments with pigs in 1895 at the Dairy 

 Institute in Proskau {Molk. Ztg., 10 {1890), Kos. l,pp. 2-5; 2, pp. IS,

Synopsis. — The followinji^ questions were discussed: (1) The value of corn as a fat- 

 tening food for yonng ]iigs, (2) inrtnenco of dillerent methods of i»reparinj;- the 

 coru, (3) the value of wliey instead of potatoes for a ration, and (4) the value 

 of brewers' grains instead of corn. 



It was found in i)revious experiments, reported in 1894 (E. S. R., 6, p. 

 77), tliat feeding a great amount of corn did not give good result.s with 

 pigs under G months old, since the animals fattened too rapidly and did
