On the contents of lime and phosphoric acid in feed rations, S. Hals 

 (Norsk Landmandsblad, 24 (1905), No. 45, pp. 567, 568).— The author shows 

 that concentrated feeds as a general rule are low in lime and high in phosphoric 

 acid, while the opposite holds true with coarse feeds. Where large quantities 

 of concentrated feeds are fed, there is therefore a danger of supplying too little 

 lime for the needs of the animals. 



In the case of milch cows producing 10 kg. of milk per day, the lowest quan- 

 tities required would he ahout 70 gm. of lime and 45 gm. of phosphoric acid. 

 This deficiency can he made good by adding mineral matter to the ration. For 

 supplementing rations relatively low in lime, precipitated dibasic calcium phos- 

 phate is recommended as superior to bone meal, bone ash, or similar very indi- 

 gestible materials. — f. w. woll. 



Experiments in calf feeding {Queensland Ayr. Jour., 16 (1905), No. 3, pp. 

 252-255). — The feeding value of 3 sorts of commercial calf feeds was studied 

 in comparison with pollard, the different feeding stuffs being fed with skim 

 milk. In 2 of the tests the calves were finished on a mixture of whole and 

 skim milk. Generally speaking, the gain on pollard and skim milk was greater 

 than on commercial feeds and was more cheaply made. 



The utilization of skim milk for calf feeding, A. Pirocchi (Rev. Gen. La it, 

 5 (1905), No. 3, pp. 49-58). — Using calves 8 to 41 days old, the value of rice 

 flour, corn meal, and starch as supplements for skim milk were studied. The 

 greatest gain per head per day was 0.97 kg. by one of the calves on maize 

 meal and the smallest gain, 0.76 kg., by one of the calves on rice meal. The 

 flesh of the calves fed maize and flour was superior to that of the calves fed 

 rice flour from a market standpoint. 



Cattle feeding (Verslag. en Meded. Afdecl. Landb. Dept. Landb., Nijv. en 

 Handel, 1905, No. 6, pp. 63, map 1). — This summary of information on cattle 

 feeding contains the following articles : Government Methods Adopted in 1904 

 for Encouraging the Cattle Industry, by F. B. LOhnis ; The Improvement of 

 Cattle, by H. M. Kroon ; and The Cattle Industry of Belgium, by S. Koenen 

 and H. Mayer Gmelin. 



Experiments in steer feeding, J. A. Craig and F. R. Marshall (Texas 8ta. 

 Bid. 76, pp. 23, figs. 4). — Tests were made with 8 lots of 5 cattle each in 1903 

 and 8 lots of 5 and 2 of 19 each in 1904, the 2 larger lots being fed on pasture. 

 Materials of interest to southern feeders, namely, rice by-products, hay of 

 different sorts, and molasses were studied, the special rations being compared 

 with a standard ration of cotton-seed meal and cotton-seed hulls. The lots on 

 pasture were fed for 196 days ; the others 60 to 100 days. 



In the first test with rice bran, this material replaced cotton-seed meal in 

 the proportion of 3:2, and cotton-seed hulls constituted the coarse fodder. 

 The average daily gain per head was 2.17 lbs. and the cost of a pound of 

 gain 4.6 cts. On cotton-seed meal and hulls similar values were 2.21 lbs. and 

 4.61 cts. The average daily gain on rice bran substituted for cotton-seed meal 

 in about the proportion of 2 : 1 was 2.98 lbs. and the cost of a pound of gain 

 3.14 cts. as compared with 2.88 lbs. and 3.23 cts. on cotton-seed meal and hulls. 



When rice bran was added to a ration of cotton-seed meal and hulls, the 

 quantity of the bran being nearly half that of the meal, the average daily gain 

 was 3 lbs. as compared with 2.6 lbs. on cotton-seed meal and hulls only, the cost 

 of a pound of gain in the 2 cases being 3.9 and 4.1 cts. 



Substituting rice polish for a part of the cotton-seed meal in a standard 

 ration resulted in an average daily gain of 2.29 lbs., the cost of the gain being 

 4.5 cts. per pound; that is, the gain was somewhat greater and the cost less
