1918] ANIMAL PRODUCTIOlsr. 771 



each were fed for 28 days and after 7 days reversed and fed for 28 days more. 

 One lot was fed a mixture of corn meal and cottonseed meaj, 7 : 8, witli corn 

 silage, and the other lot velvet beans in pod, ground, and corn silage. 



More milk and milk fat were produced on the corn meal-cottonseed meal ra- 

 tion, but the cost was lower on the velvet bean ration. 



In a second experiment two lots of four cows each were fed for the same 

 periods as in the preceding. One lot was fed corn meal and cottonseed meal, 

 4 : 3, with corn silage, and the other corn meal and velvet lieans and pod meal, 

 4 : 6, with corn silage. As in the previous experiment, more milk and milk fat 

 were produced on the cottonseed meal ration, but on the velvet bean meal ration 

 the cost was lower. With cottonseed meal at $40 per ton the velvet beans were 

 worth $15.80 per ton for milk and $15.92 for milk-fat production. One lb. of 

 cottonseed meal was equal in feeding value and economy to 2.5 lbs. of velvet 

 beans in the pod. 



The velvet beans were not palatable to all the cows. The consumption varied 

 between 11 and nearly 4 lbs. daily per animal. The milk flow and the mainte- 

 nance of body weight of individual cows on the velvet bean rations varied with 

 the amount eacli consumed. 



III. Velvet bean pasture compared loith corn and dried blood; velvet bean 

 meal compared with corn for -fattening hogs, by G. S. Templeton (pp. 118-122). — 

 The farmers of Alabama are using the velvet bean in two ways with hogs. 

 The more common method is to gather the corn after frost has killed the velvet 

 bean vines growing over it and then turn the pigs in the field. The other 

 method is to gather the ripe beans and feed as a concentrate. 



An experiment was made with three lots of pigs of five each with corn and 

 dried blood, 10 : 1, as concentrates. Lot 1 was fed a full ration alone, lot 2 a 

 half ration (2 lbs. to each 100 lbs. live weight) with the pigs on velvet bean 

 pasture, and lot 3 a one-fourth ration (1 lb. to 100 lbs. live weight) on velvet 

 bean pasture. 



Valuing tlie corn at $1 per bushel, the dried blood at $60 per ton, and the 

 velvet bean pasture at $2.83 per acre, it cost $6.59 to produce 100 lbs. increase 

 in lot 1, $4.91 in lot 2, and $4.02 in lot 3. 



In another experiment lot 1 was fed corn meal and lot 2 corn meal and velvet 

 bean meal without the pods, 1:1. It took 483.57 lbs. of the corn meal to pro- 

 duce 100 lbs. gain and 537.64 lbs. of the mixture. Valuing the corn at $1 per 

 bushel and the velvet beans at $34 per ton. it cost 8.64 cts. per pound of gain 

 with the com meal and 9.37 cts. with the mixture. 



The melting point of the lard from the corn-fed lot was 46.04° C. and from 

 the corn meal-velvet bean meal lot 44.35°. The carcasses of the latter were 

 slightly darker. All carcasses were firm.

 1915-16, D. A. GiLCHEiST (County Northitmb. Ed. Com. Bui. 25 [1917], pp. 

 8). — During the years 1912 and 1913 Germany imported an average of 248,000 

 tons palm kernels, 109,000 tons copra, 445,000 tons linseed and linseed meal, 

 217,000 tons cotton seed, 125,000 tons soy beans, and 84,000 tons peanuts. Large 

 quantities of these are now diverted to England and the experiments here re- 

 ported were made to determine the best utilization of the resulting by-products. 



Four lots of three bullocks and four of three heifers each were used in the 



trials with fattening cattle. Lot 1 was fed daily a standard ration per 1,000 



lbs. live weight made up of 78 lbs. swedes, 14 lbs. seeds hay, 2.25 lbs. soy cake, 



and 4 lbs. Egyptian cotton cake. In lot 2 the cotton cake was replaced with
