Calf feeding experiments, IIittciier (Landw. Jahrb., 38 (1909), No. 5-6, pp. 

 871-950; ahs. in MUclnr. Zcnthl., 6 (1910), A'o. 2, pp. 68-75). — In an experinjent 

 planned to study the efficacy of disastasolin 37 calves between 7 and 8 days of 

 age were used, but only 14 completed the full feeding period of 15 weeks. The 

 calves were gradually changed from whole milk to skim milk pasteurized at 90°, 

 then cooled to 65° C, to which had been added 50 gm. of starch, 2 gm. of pow- 

 dered chalk, 1 gm. of salt, and 10 cc. of a 1 per cent solution of foi'malin for each 

 liter of milk. This ration was fed in the proportion of 2.2 kg. dry matter to 100 

 kg. live weight. In the group of calves fed the ration without the addition of 

 diastasolin tlie average daily gain per head was 0.G921 kg., at a cost of G0.41 

 pfennigs (about 15.1 cts.) per kilogram. The other group made an average daily 

 gain of 0.7109 kg., at a cost of 64.97 pfennigs (about 16.24 cts.) per kilogram. 



In a comparison of cooked and raw whole milk, the best gains were made 

 with the raw milk during the first 5 weeks and with cooked milk the second 5 

 weeks, but throughout the whole period of 10 weeks there was but very little 

 difference. Powdered chalk was added to the milk of both groups. 



The average daily gains per head made by calves in 10 weeks, fed on cooked 

 and raw milk with various mineral supplements, were as follows: On cooked 

 milk and tricalcium phosphate, 774 gm. ; cooked milk and bicalcium phosphate, 

 687 gm. ; cooked milk and monocalcium phosphate, 675 gm. ; cooked milk and 

 calcium citrate, 697 gm. ; cooked milk and calcium chlorid, 644 gm. ; cooked milk 

 and salt, 803 gm. ; raw milk and salt, 866 gm. ; cooked milk and chalk, 876 gm. ; 

 raw milk and chalk, 863 gm. ; cooked milk without mineral supplement, 790 gm. ; 

 raw milk without mineral supplement, 798.5 gm. ; and raw milk with formalin, 

 702 gm.

The sterility of cattle, E. Hess (Schtoeiz. Arch. TierhciJk., J,8 (1906), No. 6, 

 pp. 351-4.il; Separate, 1908, pp. 93). — A summary of information on the causes 

 and treatment of abnormal conditions in cows which are directly or indirectly

 subject. 



Feeding experiments with sheep, A. Lalim (Norsk Landmandsblad, 29 

 (1910), Xos. 2, pp. 17-20; 3, pp. 36--'il). — Experiments were conducted at 5 

 different Norwegian farms for the purpose of determining how much hay 

 mature sheep require for the maintenance of body weight during the winter 

 months when they receive hay and water only. 



It was found that sheep weighing between 50 and 70 kg. at the beginning of 

 the trials were able to maintain their weight on a daily ration of from 1.01 

 to 1.46 kg. of hay per head. Analyses of the hay fed showed that these 

 amounts contained from 0.90 to 1.31 kg. dry matter, 0.07 to 0.15 kg. protein, 

 0.02 to 0.03 kg. fat, 0.47 to 0.67 kg. nitrogen-free extract, and 0.24 to 0.47 kg. 

 fiber.
