rations. The digestibility was determined, as well as gains in weight. The 

 results reported emphasize the authors' general conclusion regarding the high 

 efficiency of bone phosphate in calf feeding. That lime is no less necessary 

 than phosphoric acid is also pointed out. For earlier work see previous notes 

 (E. S. R., 10, p. 294; 19, p. 468). 



Skim milk for raising and fattening calves, L. Maxpeaux {Soc. Aliment, 

 lintloim. Bctail, Comijtc Rendu 11. Cong., 1907, pp. 1-10, 126, 127, dgms. 2).— A 

 l)aper with discussion. According to the author, 2 calves fed for 84 days on pan- 

 skimmed milk gained on an average 0.945 kg. per head per day as compared 

 with 0.S92 kg. in the case of similar calves fed the separator-skimmed milk. 



In a comparison of pasteurized with raw sweet milk, it was found that the 

 average daily gain of 2 calves in 112 days on the former was 0.888 kg. per 

 head and on the latter 0.844 kg. In a similar comparison of skim milk and sour 

 milk the average gains were respectively 0.843 kg. and 0.776 kg. 



When denatured sugar was used to supplement skim milk in calf feeding the 

 average daily gain in 85 to 112 days was 0.964 kg. per head as compared with 

 0.867 kg. hi a similar test in which starch was used. 



Denatured sugar and a decoction of flaxseed were also compared as supple- 

 ments for skim milk. In 153 days the average daily gain of the 2 calves on the 

 former was 0.250 kg. and on the latter it was 0.225 kg. 



As the author points out, the 20 per cent of feeding cake used for denaturing 

 the sugar added to its nutritive value. Forty to 45 gm. of sugar per liter of 

 skim milk is advisable. Large quantities cause scouring.

The improvement of Egyptian rattle, T. P. Goodchild {Yearbook Khediv.

 selection and that crossing with other sorts of cattle would not give satisfactory 

 results. Management of cattle under local conditions, the utilization of 

 Egyptian feeding stuffs, and other matters are considered.
