380 EXPERIMENT STATION RECORD. 



The average weight at the beginning was 30.58 kg. One lamb was 

 dropped from the test before the close. All the lambs received a basal 

 ration per 1,000 kg. live weight of 8 kg. alfalfa hay, 8 kg. straw and 

 chaff, 6 kg. dried beet chips, and 5^ lbs. rape-seed cake. In addition, 

 lot 1 was fed U kg. molasses and 4£ kg. bran: lot 2, 9 kg. molasses 

 bran; lot 3, 4.1 kg. wheat bran and <».(»!) kg. molasses peat (containing 

 4. 1 , kg. molasses); and lot 4, 4.} kg. wheat bran and 11.15 kg. molasses 

 peat (containing 11 kg. molasses). In the case of lot 1 the molasses 

 was cither given in the drinking water or mixed with some other food. 

 In the other cases a mixed molasses feed was used. All the rations 

 furnished 3.49 kg. digestible protein; the first 3 furnished 16.05 kg. 

 nitrogen-free material, and the last 18.21 kg. The cost of the rations 

 for the different lots was as follows: Eot 1, $52; lot 2, $54; lot 3, 

 $53.15; and lot 4, $55.86. The average gains for the corresponding 

 lots were 2(18.5, 288.5, 278.5, and 286.5 kg. 



The principal conclusions reached were the following: Molasses can 

 be regarded as a rational feeding stuff for fattening lambs. The feeding 

 value of molasses not mixed with other material is slightly less than 

 that of the mixed molasses feeds. Molasses peat and molasses bran 

 have the same food value, but (at current prices) the molasses-peat ration 

 was somewhat cheaper. In the rations tested increasing the nitrogen- 

 free material by the addition of a large amount of molasses was not 

 profitable. The author discusses the financial returns with and without 

 the value of the manure. 



Influence of different protein compounds on the gain of flesh in 

 swine, O. Hagemann (Milch. Zig., 26(1897), No. 48, pp. 762-764).— -The 

 author calls attention to the fact that myosin (the chief nitrogenous 

 constituent of flesh) contains 10 per cent of nitrogen, while the nitrogen 

 content of the proteids in feeding stutts varies, being, for instance, 18.2 

 per cent in case of peanut cake. In the author's opinion myosin can 

 not be formed from the excess of nitrogen in proteids over 16 per cent. 

 A method is proposed for calculating the amount of available protein 

 in different feeding stuffs. Few details are, however, given. 



Experiments were made with 8 pigs. From the time they were 8 

 weeks old until the beginning of the test proper the pigs were fed 

 barley meal, consuming on an average during the 12 days 644 gin. and 

 gaining 6L gin. in weight daily. The pigs were then divided into 4 lots 

 of 2 each. Lot 1 was fed meat meal and potatoes; lot 2, corn meal and 

 later ground oats; lot 3, barley meal; and lot 4, peanut cake and pota- 

 toes. In addition, all the lots were given salt, calcium phosphate, 

 magnesium phosphate, and potassium chlorid, the amounts being in 

 such proportion that the ash content of the different feeding stuffs was 

 equalized. The amounts of food consumed, the nutritive ingredients, 

 the total nutritive material, the nutritive ratio, and the gains in weight 

 are recorded for the whole experiment, which lasted from August 14 to 

 January 31. The total nutritive material was found by adding together
