194 FEEDS AND FEEDING 



recommended by Doctor Hadley of the "Wisconsin Station 20 is : Common 

 salt, 280 Ibs. ; dried iron sulf ate, 16 Ibs. ; powdered wood charcoal, 12 Ibs. ; 

 and flowers of sulfur, 8 Ibs. These materials should be well mixed or 

 ground together to make a powder. This mixture, which, it will be 

 noted, consists chiefly of common salt, should be kept in suitable boxes 

 so that the animals may have free access to it. 



Artificial Carlsbad salt has recently come into vogue among veteri- 

 narians, as a conditioner, especially for horses. The formula for this 

 is as follows: 21 Dried sodium sulf ate, 40 parts by weight; sodium 

 bicarbonate, 35 parts ; common salt, 15 parts ; potassium sulf ate, 2 parts. 

 The ingredients should be mixed and powdered. For mature horses 1 to 2 

 heaping tablespoonfuls, and for mature cattle 1.5 to 3 heaping table- 

 spoonfuls should be given 2 or 3 times daily on the feed. The dose for 

 swine or sheep is one-fifth as much as for horses. Half-grown animals 

 should be given half as much as mature animals ; younger ones one-eighth 

 to one-fourth the full dose ; and sucklings one-sixteenth the full dose. 



292. Mineral mixtures; vitamine preparations. At the present time 

 many proprietary mineral mixtures and mineral tonics are being widely 

 advertised. While some of these are honest efforts to supply the minerals 

 which may be lacking in certain rations (95-101, 119, 149), others are 

 of poor quality and are bolstered up by high sounding names and un- 

 warranted advertising claims. In spite of frequent assertions to the 

 contrary by the manufacturers of such preparations, there is no scientific 

 evidence that any such mineral mixture will prevent or cure contagious 

 abortion. This must be clearly distinguished from non-contagious 

 abortion, which may be produced by a deficiency of lime in the feed of 

 pregnant animals. (98) Furthermore, there is no evidence that healthy 

 animals are benefited by such substances as Epsom salts, Glauber 's salts, 

 sulfur, potash salt, or copperas, which are contained in many proprietary 

 mineral mixtures. Sick animals need a veterinarian or a specific remedy, 

 not a "cure all." Any mineral supplements needed by stock can be 

 supplied cheaply and easily without paying high prices for proprietary 

 mixtures. (574, 18) 



On account of the great popular interest in vitamines, certain mixed 

 feeds are being extravagantly advertised as being high in vitamines, and 

 likewise certain proprietary mixtures which are said to be rich in vita- 

 mines and are claimed to produce marvelous results. From the facts 

 which have been reviewed earlier, it is evident that live stock fed ordinary 

 good rations have no lack of the water-soluble vitamine. Hence there is 

 no need of supplying them with any yeast preparation, so far as is now 

 known. In fact, if stock are fed as recommended in this volume, there 

 should be no lack of a.ny vitamine whatsoever. Before paying his good 

 money for any mineral mixture or vitamine preparation, the wise stock- 

 man will secure unprejudiced advice from his experiment station.
