"Fortunately no serious adulterations of concentrated feeding stuffs are practiced 

 in this State, so far as we have been able to ascertain, beyond the admixture of low- 

 grade oat refuse feeds in mixed corn and oat feeds, which ... is quite common: 

 the admixture of screenings to mill feeds, especially bran, is still i)racticed by a few 

 mills, but the (juality of tlu' mill feecl sold in our State is, on the whole, of a high 

 grade." 



The care of farm stock (Ihil. Mnhif I), pi. Acjr., 2 {1903), No. 4, PP- 10.5-143).— 

 Short articles by a lunuber of different authors are included on topics dealing -with 

 the feeding and care of farm animals. 



Empirical knowledge and experience in the feeding- of farm animals, 

 L. (Jkandk.m: {Jour. Agr. Trat., n. .<<er., 7 {1904), -V"- -i, PP- ^, 10). — The fact is pointed 

 out that the feeding of farm animals may be said to rest on a scientific basis. The 

 jirogress made in recent years is biiefly discussed. 



Calf-rearing experiments {Jour. Ikpit. Agr. and Tech. TiiMr. Ireland, 3 {1903), No. 

 4, pp. <iJ7-G47, dgiii.s. 4). — Whole milk, separator skim milk and whole milk 5:1, 

 sejiaratoi- skim milk sujiplemented by cod liver oil, and separator skim milk supple- 

 mented by corn meal were compared with 4 lots of from 7 to 9 calves at Knockbeg, 

 Collooney, Ireland. The test began June 12, 11)01. In 20 weeks — that is, when 

 weaned — the gains per head ranged from 176.2 lbs. on skim milk and cod liver oil to 

 238.6 lbs. on whole milk, the cost of a pound of gain ranging from 3.42 cts. on skim 

 milk and corn meal to 7.98 cts. on whole milk. The feeding was contmued until 

 February 16, 1903, when the calves were sold for fattening. Considering the test as 

 a whole, the total gain ranged from 698.5 lbs. with the lot originally fed cod liver 

 oil to 760.6 lbs. with the lot originally fed whole milk. 



Beginning June 12, 1901, a second test Avas made with some of the older calves 

 secure<l at the same time as those included in the above test. The calves were weaned 

 earlier, the weaning period beginning early in August, and they were sold for fatten- 

 ing February 16, 1903. The rations fed throughout the test were practically the same 

 as in the first test. Considering the entire period, the gains ranged from 678.5 lbs. 

 with the lot originally fed skim milk and corn meal to 759.7 lbs. with the lot origi- 

 nally fed skim milk and cod liver oil. The gains were also most cheaply made by 

 this lot. 



It is stated that the experiment furnishes a demonstration of the fact that calves 

 may be successfully reared on skim milk provided a cream substitute is fed with it; 

 that they may be more economically reared on skim milk and a cream substitute 

 than on whole milk; and that the belief generally held locally that creamery milk 

 is the cause of the high death rate among calves is entirely imfounded. 



Fattening steers of the various market grades, H. W. Mumford {lUlnohSia. 

 ]M. 00, pp. 155-317, ph. 13). — The principal object of this experiment was to deter- 

 mine the relation between the grade of the steers fed and their feeding qualities— 

 that is, whether the (juality of an animal determines its capacity for making gains, 

 the ability to use feed economically, and the nature of the gains made. The grades 

 chosen were fancy selected, choice, good, medium, common, and inferior steers, 16 

 animals constituting a lot in every case. 



After a ])reliminary jieriod all the lots were fed alike for 129 days, beginning 

 November 29, 1902. The grain ration for the early i)art of the test consisted ot 

 (chopped corn and cob and later of corn-and-cob meal, with about 8 lbs. of cotton- 

 seed meal or linseed meal per bushel of corn in addition. The coarse fodder con- 

 sisted of clover hay, timothy hay, and later, of alfalfa hay, which through the greater 

 part of the te.st was choppe<l and mixed with the grain. A little corn stover was
