meal liad no bad effect upon the health of the cow, while the yield of milk was 8 per 

 cent higher than with the cocoanut-meal feed. The fat content of the milk was 4.24 

 per cent daring the first cocoanut-meal period, 3.58 during the vetch-seed-meal 

 period, and 4.38 during the concluding cocoanut-meal period. 



The test with pigs covered 70 days. Two of the pigs were fed vetch seed alone, 

 vetch and milk, or vetch and barley. For a few days barley alone was given. Two 

 similar pigs were fed l)arley alone at first, and later barley and milk. The.grains 

 were coarsely ground. On the first ration the total gain was 18.265 kg. and on the 

 second 21.726 kg. One pig in each lot was then slaughtered and the feeding con- 

 tinued with the other, hay meal being added to the rations. In 18 days the pig fed 

 the vetch ration gained 10.249 kg. and the pig fed barley 15.579 kg. In this test it 

 was observed that the pigs did not eat the vetch with great relish, and sometimes it 

 was refused. The author believes, however, that vetch seed may be profitably used 

 as a feeding stuff for pigs, although some caution must be observed. On the other 

 hand, vetch was found to be a very satisfactory feeding stuff for milch cows, and at 

 the same time, according to the author, it is very cheap. 



Concentrated feed stuffs; condimental stock and poultry foods, J. ]\. Lind- 

 SEV {Massachusetts Hatch Sfu. Bui. 71, pp. 40).— A. large number of analyses of feeding 

 stuffs are shown in tables, giving the brand, manufacturer, source, and the protein 

 and fat guaranteed and found. The various feeds are divided into 4 classes, with 

 reference to their protein content. For New England conditions, the most econom- 

 ical concentrated feeds in the author's opinion are cotton-seed meal, corn-gluten 

 meal, gluten feed, dry brewers' grains, malt sprouts, and fine flour middlings. 

 Expensive feeds are wheat bran, linseed meal, and so-called mixed feeds. The latter 

 especially are undesirable, on account of being so often adulterated. Therefore it is 

 usually more economical for the feeder to make his own mixtures. For this purpose 

 tables of desirable mixtures are given. Of the 11 samples of cotton-seed meal not 

 guaranteed, 8 were found to be largely adulterated. Farmers are therefore urged to 

 purchase only guaranteed meals. The gluten meals and feeds were free from adulter- 

 ation and usually of excellent (piality. A large number of the so-called oat feeds 

 were of very inferior quality, and, while costing nearly as mucli as corn, are only h to 

 I as valuable. 



A large number of analyses of condimental stock foods and condition powders are 

 reported and the substances found in them discussed. They were found to consist 

 principally of cereals, oil meals, and by-products. In some, condiments as fenugreek 

 and gentian were found, as well as various other products, as salt, sulphate of magne- 

 sium, soda, charcoal, sulphur, and, in poultry foods especially, ground oyster shells, 

 charcoal, and pepper. The condition powders varied very imicli in t-()mj)osition, 

 but in general the author believes were (jf very little value, and in mi way merited 

 the strong claims made for them by the manufacturers. Their cost is excessive, 

 and in no case are they necessary to the health of the animal. 



Commercial feeding- stufifs in the Connecticut market ( Connecticut Stale Sta. 

 Bui. 133, pp. i'S). ^Agents of the station collected in the 25 towns and villages of 

 the State 186 samples of commercial feeding stuffs. The results of analysis are 

 shown, giving the chemical composition, the digestible nutrients, and the cost per 

 ton. A list showing the average weight of 1 qt. of each of the feeds named is also given. 

 With the exception of cotton-seed meal, old-process linseed meal, and hominy 

 chops, the percentages of fat in these feeds was not very unlike, ranging between 

 2.4 and 5.5 per cent. As the ])rotein is the nutrient which the feeder is chiefly con- 

 cerned in getting, a comparison is shown of the cost of that ingredient in each of 

 the classes of foods. If 20 lbs. of protein in cotton-seed meal cost %0.M, then 20 

 lbs. of protein in gluten meals cost about $0.85, in gluten feeds $0.88, in wheat feeds 

 $1.20, in oats, corn, provender, corn chop, etc., $1.77, and in oat feeds and other 

 trash $2.10. This is a rough but practically just statement of the comparative cost
