76 EXPERIMENT STATION RECORD. [Vol. 40 



made to determine the value of skim milk as a supplement to corn and other 

 cereal grains when fed to pigs. It is pointed out that 415 pigs fed cereal grains 

 only made an average gain of 100 lhs. from 4S6.5 lhs. of grain and that 325 

 pigs fed cereal grains supplemented by skim milk made an average gain of 100 

 lbs. from 26G.9 lbs. of grain and 785.1 lbs. of skim milk. This indicates that 

 100 lbs. of skim milk replaced 28 lbs. of grain. Calculated on the basis of 

 $50 to SS0 per ton for the different grains used, which included corn, wheat, 

 rye, and barley, the value of the skim milk ranged from 0.7 to 1.2 cents per 

 pound. Attention is also called to the fact that this summary showed much 

 greater returns from the skim milk when 2 to 3 lbs. of milk was fed per pound 

 of grain than when the milk was fed in larger quantities. 



Velvet bean feed for pigs, H. W. NaBTON, jr. (Michigan Sta.. Quart. Bui., 1 

 (1918). No. J. pp. 7, 8).— Seven lots of thrifty pigs weighing from 90 t<> 125 

 lbs. at the beginning of the test were fed velvet beans in the pods and velvet 

 bean feed consist ing of the ground beans and puds. Those foods were used 

 singly and in combinations with middlings, corn, and tankage. The first lot 

 was fed the velvet beans in the pods dry through a self-feeder, while the 

 other lots received the feed as slop. On the basis of $37.50 per ton for on- 

 ground velvet beans and pods, $40 per ton for velvet bean feed, $40 per ton 

 for wheat middlings, $60 per ton for corn, and $100 per ton for tankage, the 

 feed cost per pound of gain in the first lot amounted to 41.7:: its., and in the 

 lot receiving velvet bean feed alone to 30.88 cts. The cheapto«d gain by far, 

 the feed cost per pound of gain being 10.SG cts., was made by the cheek lot 

 fed 10 parts of corn and 1 part tankage. 



Second annual report for the year 1917 by the Oklahoma State Livestock 

 Registry Board (Oklahoma Sta. Circ. ',', (1918), pp. Ill, this. 71.— This report 

 contains the text of the State live stock registration law and rides and regula- 

 tions adopted by the board for its enforcement, and gives lists by breeds and 

 counties of the stallions and jacks licensed in the State in 1017. Lists of the 

 horse and jack registry associations recognized and not recognized in Oklahoma 

 and a list of the States having stallion laws are also given. A number of popu- 

 lar articles on raising and handling horses are included. 



The value of skim milk and meat scraps for White Plymouth Rocks, A. C 

 Philips (Indiana sta. Bui. 218 (1918). pp. 20. figs. 4).— The results are re- 

 ported of feeding experiments with pullets and with hens. The experiments 

 with pullets, conducted for three consecutive years beginning in December, 1914, 

 Included ao annual series of three pens, each receiving a mixed grain ration 

 made up of corn and wheat, 10 lbs. each, and oats 5 lbs. with a mash consist- 

 ing of 5 lbs. each of bran and shorts. In addition to this allowance one pen 

 received 50 lbs. of skim milk and another pen 3.5 lbs. of meat scrap, th< 

 quantities furnishing approximately the same amount of protein, During the 

 winter the corn was increased to 15 lbs., the wheat reduced to 5 lbs., and in 

 the fall 1 lb. of oil meal was added. Grit, oyster shell, and dry bone wore 

 always available as was also water, except in the skim milk pen. When not on 

 range the birds were fed mangels. The bran and shorts wore fed together as a 

 dry mash. The skim milk was fed in an open pan and the meat scrap was 

 mixed with the mash. 



The average annual consumption of feed per fowl was 97.68 lhs. for the 

 moat scrap pen, 83.24 lbs. for the check pen, and 201.82 lbs.. Including 115.74 

 His. of milk, for the skim milk pen. the cost being $1.69, $1-37, and $1.79, 

 respectively. The cost of feeding a pullet on a good ration averaged about 

 81.7o in 1010 and nearly 82.50 in 1017. No difference in feeding capacity 

 between good and poor layers was observed. The use of skim milk and meat 

 scrap increased the efficiency of the grain. The average cost of producing 1
