Feeding Stuffs for January. 



[Jan., 



diseased and frosted potatoes steaming or cooking should be 

 adopted if it is desired to feed them. 



Maize Gluten Feed. — This fairly cheap nitrogenous feeding 

 stuff is at present on the market, and several correspondents 

 have asked for information as to its feeding value. Maize gluten 

 feed consists of a mixture of the by-products obtained in the 

 manufacture of maize starch and can be regarded as the maize 

 grain with most of the starch removed. It is rich in oil and 

 protein and is well suited for dairy and fattening stock. This 

 feeding stuff has been included in the table in order that 

 Journal readers may obtain some idea of its relative value for 

 feeding. 



The Mineral Requirements of Pigs. — Owing to tlie nature of 

 their diet, pigs are very often fed on foods deficient in the ash 

 constituents that are necessary if they are to remain in good 

 health and grow satisfactorily. Such substances are roots and 

 maize products. This deficiency will also occur where pigs are 

 kept on the open-air system on light land farms. On American 

 Agricultural Experimental Stations, much attention has been 

 paid to the question of the mineral requirements of pigs, and 

 experiments have been undertaken, particularly at the Iowa 

 Experiment Station, under the direction of Professor Evvard. 

 As the result of many experiments tlie following mixture has 

 been suggested tentatively as a suitable complete mineral mix- 

 ture for pigs : — 



lb. 



Salt, common, flake form ... ... ... ... ... BO'O 



Spent bone black, or bone meal, finely grounri or bone flour 25"0 

 Commercial kainit, or potassium chloride, or wood ashes ... 12-0 

 Sulphur, flowers of ... ... ... ... ... ... 100 



Air-slaked lime, or limestone, finely ground ... ... ... lO'O 



Glauber's salts or sodium sulphate ... ... ... ... 5-7 



Epsom salts or magnesium sulphate ... ... ... ... 5'0 



Copperas, or iron sulphate 2*0 



Potassium iodide ... ... ... ... ... ... 3 



100-0 



This miixture does not represent the final word on the sub- 

 ject, and the station is still engaged in putting experimental 

 knowledge to practical test. Pig feeders, however, will probably 

 find that the use of this mixture will help to condition their 

 pigs and keep them in good growing condition. About 1 lb. 

 per month per adult pig is the suggested allowance when hand- 

 fed. For those who wish to have a fairly simple mineral
