ii)g, and corn meal alone after weaning ; lot 2, corn meal and milk before 

 and after weaning; lot o,corn meal and shorts before and after weaning; 

 lot 4, corn meal and ground oats before, and corn meal an<l barley after 

 weaning. 



The pigs were all weaned when 70 days old ; after this thefeedingwas 

 continued in 1S89 for from a mouth to a month and a half, and in 1890 

 for 7 weeks. The details of the trials, including the amounts of Iced 

 consumed, the weight of the animals, the feed required per 100 pounds 

 of gain and cost of the same, for each lot before and after weaning, are 

 tabulated. 



In 1S89 the average cost of food consumed per 100 pounds of gain in 

 live weightwas,for sowand pigs before weaning. $3.14, and for the pigs 

 after weaning, $2.85, allowing 25 cents per 100 pounds for the skim-milk 

 and $14 per ton for the graiu mixture. Three of the sows gained 

 respectively 29, 33, aud 4 pounds, and one lost G pounds while suck- 

 ling the pigs. 



The teaching of these trials is that it pays to feed sows when suckling pigs so 

 heavily that even the dams will gain in weight, for the cost of the gain made by 

 the pigs and their dam is then cheaper than the gain of the same pigs when grown. 



[In 1889] the combination of corn meal aud skim-milk gave excellent results, and 

 corn meal with shorts did equally well. Where the sow was fed ground oats poor 

 returns followed, tliis feed not being very satisfactory when cost [!$18 per ton] is con- 

 sidered. There was little difference in the amount of food required for .i pound of 

 growth with the pigs of lots 2 and 3 before aud after weaning, and we may conclude 

 that there is no cheaper way of feeding pigs thau through the dam. * * * 



This year [1890] we produced gain somewhat cheaper while the pigs were with the 

 sow thau after they were weaned, while last year [18S9] the reverse was the case. 

 Averaging the trials for the 2 years [at the prices of feeding stufts given above] we 

 have $2.87 as the cost of producing 100 pounds of gain with pigs before they are 

 weaned, and $2.75 per 100 j^ounds gain as the cost of food for pigs immediately after 

 ■weaning, a difference of $0.12 per 100 pounds gain. 



Ground barley for fattening hogs (pp. 53-59). — (1) Ground barley vs. 

 corn meal. — To compare the value of barley and corn, ten pigs, 391 to 

 407 days old at the beginning of the experiment, were divided into two 

 lots of five each, one lot being fed barley meal and the other corn meal 

 during 8 weeks. 



(2) Barley meal and sMm-milk vs. corn meal and sicim-milk. — During 



9 weeks six pigs, 130 to 140 days old, were fed barley meal and skim- 

 milk, and six others, of the same age, were fed corn meal and skim milk. 

 The amounts of food consumed, and the weight of the individual pigs 

 are tabulated for each trial. 



In these experiments barley meal was found a very satisfactory feed for hogs, 

 tliough they did not make quite as good a gain in either case as did those fed on corn 

 meal. In both trials it required about 8 per cent more barley meal, by weight, thau 

 corn meal to make 100 pounds of gain. » » « The barley-fed hogs drank a great 

 deal more water than those getting corn. 



Cooked potato(.s for fattening hogs (pp. 59-01). — Six lots of pigs, ;ibnnt 



10 mouths old, were fed during 42 days as follows: lots 1 and 5, corn
