Pigs weighing an average <»f 72 lbs., self-fed on corn and tankage separately, 

 consumed an average of eight parti of corn to one of tankage during the first 

 seven weeks of an experiment, al the close of which they averaged 128.3 lbs. 

 in weight, and during the remaining 7 weeks of teal they consumed it.j lbs. of 

 corn to l n». of tanks 



in another ezperlmenl three lots of pigs given, resj tlvely, l, 8, and S lbs. 



of skim milk to l lb. of corn and a fourth lot given twice dally all the skim 

 milk and corn they would consume, were compared with a lol fed corn alone 

 and another lot fed corn and tankage, '.» : l. At the prices given above and 

 placing the value of skim milk al 60 cts. per 100 lbs., the pigs fed .". lbs. of milk 

 to 1 lb. of corn made the most economical gains The cost of feed Cor the lot 

 fed corn alone was $8.38 above the value of the trains. For the other lots the 

 value of gains over cost of feed was as follows: Corn and tankage 9: 1, $14.91; 

 corn and skim milk 1 : 1, $20.62; corn and skim milk 1 : ?,, $35.59; corn and skim 

 milk 1 : f>, $14.4.".; and corn and skim milk ad libitum, $18.62. 



Peanut meal and velvet bean meal for fattening swine, II. E. Dvobachek 

 and 11. A. SANDH0TJ6E {Arkansas Sta. Circ. ^5 (1918), pp. //). — The high price 

 of tankage and limited quantities available suggested the two experiments here 

 reported, In which peanut meal and velvet-bean meal wore compared with 

 tankage as supplements to corn in fattening young pigs. 



In the first experiment IS shotes, averaging 115 lbs. in weight, were divided 

 Into three lots, each receiving corn and one of the three supplements fed sepa- 

 rately by the free-choice self-feeder system. In the other experiment 15 shotes, 

 weighing about 100 lbs. each, were fed the same way, except that the lots were 

 hand fed and the supplement was mixed with eight times its weight of ground 

 corn chop. The first experiment lasted 11 weeks and the second 10. Results 

 are given in the following table: 



Comparison of supplements to earn in fattening shotes. 



Costs were figured on the following market prices per hundredweight: Corn. 

 $3.20; velvet bean meal, $2.50; peanut meal, $2.85; and tankage, $5.20. The 

 velvet bean meal proved unpalatable, so that the hogs when self-fed ate but 

 little of it and made their gains on corn. When it was mixed with corn and 

 fed by hand they ate little more than a maintenance ration. Peanut meal was 

 much relished and was consumed freely. The lots receiving it made the largest 

 gains in both experiments, and these gains were also the cheapest It is, there- 

 fore, considered to be an excellent substitute for tankage in the South. 



Garbage feeding and the care of garbage fed swine, R. R. Birch (Cornell 

 Vet., 8 (1918), Xo. 1, pp. 26-37).— This article advocates the more extensive use 

 of garbage in pig feeding. In view of the successful development of hog-cholera 

 serum. Replies are given to a questionnaire sent to the mayors of 50 New York 

 cities concerning the local methods of garbage disposal and the possibility of 

 utilizing hogs for this purpose.
