FOODS ANIMAL PRODUCTION. 577 



The author discusses the tests as a whole aud draws the following 

 general conclusions: 



"(1) Both range lambs and home-grown lambs are well adapted for feeding. 



"(2) The value of the increase made from feeding lambs in our State is more tlian 

 the cost of the food used in making it. 



"(3) The coarse cereals which Minnesota produces are well adapted to the 

 fattening of lambs when suitably blended. 



"(4) When lambs are being fattened, considerably superior gains will be obtained 

 when the grain food contains at least 10 per cent of oil cake. 



"(5) Oil cake, barley, and oats, suitably blended, with or without bran, makes an 

 excellent grain food for fattening lambs. 



" (6) While good gains may be secured by feeding oats and oil cake, suitably 

 blended, the dearness of the mixture makes it too costly to furnish the highest 

 profit. 



"(7) Excellent gains can be secured when fattening lambs in our climate in the 

 absence of held roots or silage. 



"(8) Under the conditions which have prevailed during the past three years, an 

 average of about $1 per head could be secured from feeding lambs judiciously for 

 about 100 days." 



Peanuts, cowpeas, and sweet potatoes as food for pigs, J. F. 

 Duggar (Alabama College Sta. Bui. 93, pp. 115-134). — Feeding experi- 

 ments with peanuts (pp. 117-121). — Immediately after weaning Poland 

 China pigs were hurdled on a field of Spanish peanuts aud given some 

 shelled corn in addition. The test began in September and covered 6 

 weeks. The peanuts were eaten readily from the first and as long as the 

 vines remained green a considerable portion of the leaves was also 

 eaten. The yield of peanuts was 62.G bu. per acre. The 6 pigs weighed 

 at the beginning of the test 181.3 lbs., and gained 19G.4 lbs., consuming 

 373 lbs. of shelled corn, besides the peanuts and some foliage from 7,673 

 sq. feet. That is, 1.1 lbs. of peanuts and 1.9 lbs. of corn, together with 

 an unknown quantity of peanut foliage, were consumed per pound 

 of gain. Valuing the corn at 40 cts. per bushel and the pork at 

 3 cts. per pound, the profit from the peanuts was $3.23 or at the rate of 

 $18.31 per acre. The author points out that this was poor sandy 

 upland which would not have produced over 200 lbs. of lint cotton per 

 acre worth $10 to $12. The expense of cultivating the peanuts was 

 less than for a similar area of cotton and in addition the soil was 

 benefited by the manure and the peanut vines. 



To compare peanut pasturage and corn meal a second test was made 

 with 6 Essex pigs of about the same age, divided into 2 lots. Lot 1 was 

 hurdled on peanuts which were planted the last of June following 

 wheat, and given as much corn in addition as the pigs would eat. 

 Lot 2 was hurdled on peanuts but given no grain. After a preliminary 

 period of a week the test began November 1 aud continued 4 weeks. 

 Lot 1 grazed over 2,025 sq. ft. of peanuts and gained 38.6 lbs., consum- 

 ing 2.06 lbs. of corn per pound of gain in addition to the peanut 

 forage. Valuing the corn and pork at the prices given above, the 

 l)eanuts yielded a profit of $10.94 cts. per acre. Lot 2 grazed over
