51| lbs. The amount received for the steers was $585.16, which gave 

 a profit of $82.44. Allowing for shrinkage, there was $20.05 less profit 

 than there would have been if the steers had been sold at the end of 

 the experiment proper. 



In the author's opinion the tests show the imj^ortance of selling fat 

 animals with promptness. Neither of the breeds tested was markedly- 

 superior. The author concludes that it is profitable to fatten cattle 

 under the existing conditions. 



Experiments with skim milk feed, J. Lindstrom {NorsJc Land- 

 mansblad, 15 {1896), pp. 155, 156). — Experiments were made with skim 

 milk as a food for farm animals, and especially for milch cows. The 

 milk was heated to 80 to 85° C. for one-half hour, then cooled to 35 to 

 40°, and rennet added. While the milk "was thickening an equal 

 quantity of chaff or fine cut straw was added ; the mixture was stirred 

 and left for 2 to 3 hours; the unabsorbed whey was run off, and the 

 mixture left to ferment for 45 to 48 hours, when it was ready to be fed. 

 As much of the feed is given to milch cows as would equal 4 kg. of 

 milk per head per day. In the author's opinion this amount will 

 amply replace 2 kg. of common mixtures of concentrated feeds (bran, 

 oil cakes, etc). 



Several practical feeding tests with this skim-milk feed are given^ 

 elsewhere. — f. w.woll. 



Economy of feeding "with home-grov^n -wheat and barley, J. A. 

 VoELCKER [Jour. Roy. Agl. Soc. England, ser. 3, 7 {1896), No. 25, pp- 

 39-53. 



Synopsis. — Experiments were made with steers and sheep to see whether home- 

 grown wheat and barley could be economically substitued for part of the cake 

 fed in a ration. The conclusion was reached that setting aside the fertilizing 

 value, such a substitution might be advantageously made under the prices then 

 prevailing for wheat and barley. 



These experiments were made at the Woburn Experimental Farm in 

 1894-'95 with steers and sheep. The object was to see if home-grown 

 wheat and barley, which are cheaper, could not partially replace oil 

 cakes. In experiments previously reported ^ home-grown barley and 

 wheat were substituted for all the oil cake in a ration. 



Experiments ivith steers. — Twelve Hereford steers, costing $72.75 per 

 head, were fed in a preliminary period lasting from October 16 until 

 December 10, 1894, a very moderate diet, and just held their own. The 

 experiment proper began December 10. Steers Nos. 1 to 8 were fed in 

 feeding boxes and ]S'^os. 9 to 12 in a covered shed. They were divided 

 into 2 lots. Lot 1, including Nos. 1, 2, 3, 4, 9, and 10, was fed oil cake and 

 no grain, and lot 2, including Nos. 5, 6, 7, 11, and 12, was fed a limited 

 amount of oil cake with grain enough to make a full ration. In addition 

 each lot received Swedes and barley straw ad libitum. The steers were
