1114 EXPERIMENT STATION RECORD. 



and fattens them on rather less food, but does not produce quite so good a carcass of 

 pork." With milch cows gluten feed "did not give quite such good results as an 

 equal weight of decorticated cotton-seed meal similarly fed." 



Report of the agriculturist, W. L. Caklyle (Colorado Sta. Rpt. 1904, pp. 101- 

 105). — Brief notes are given regarding feeding testa with steers, lambs, and pigs, and 

 plans for experimental work in horse breeding are spoken of. 



In a test made with 3 lots of 50 steers each, rations of beet pulp and alfalfa hay 

 with and without grain were compared. The greatest gains were made by the lot 

 fed corn in addition to the basal ration and the least gains by the lot fed no grain. 

 The greatest profit, $16.60 per steer, was noted with the lot fed no grain, and the 

 least, $12.55 per steer, with the lot fed barley and oats. When 100 lambs were 

 pastured for 7 weeks on field peas ready for harvesting the average gain was 17 lbs. 

 each. 



To secure data of interest to those engaged in the pig industry an accurate account 

 was kept of the cost of feed eaten and the gains made by 10 sows and their pigs. 

 Deducting the first cost of the sows and the cost of feed while nursing the pigs, they 

 returned a profit of $31.25. The pigs were fed in 3 lots of 24 each, one lot being 

 pastured on alfalfa, one on rape, and one on barley and field peas. Mixed grain was 

 fed to all the lots in addition to pasturage. On an average 3.5 lbs. of grain was 

 required per pound of gain. The profit on the pigs was $248.55. 



The improvement of poor pastures (Jour. Bd. Agr. [London], 11 (1905), No. 10, 

 pp. 608-613). — The results of experiments are summarized which were carried out 

 by the agricultural department of the University of Cambridge at Cransley, North- 

 ampton, on the improvement of pasturage manured in different ways, as shown by 

 the gains made by sheep grazed on sample plats. 



In the 3 years the greatest total gain in live weight, 337.2 lbs., was made by the 

 sheep pastured on the land manured by feeding decorticated cotton-seed cake for 

 2 years. The smallest gain, 158.9 lbs., was made on the pasture which was not 

 manured. 



The chief lesson which may be drawn from the investigation, it is stated, is that 

 on clay soils the improvement of poor pastures must begin with a heavy dressing of 

 basic slag, no other manure being usually necessary. It is essential, however, that 

 the pasture contain clovers, otherwise the basic slag will not be of use. The quantity 

 of manure will vary according to circumstances, 7 to 10 cwt. per acre being the usual 

 amount. The ultimate improvement, it is stated, wiil depend on the extent to which 

 clover grows during the first year or two. 



Improvement of hill pasture as determined by the effects on stock. Experi- 

 ments in Scotland, D. Wilson (Trans. Highland and Agr. Soc Scotland, 5. ser., 17 

 (1905), pp. 271-295). — Tests carried on in different localities of Scotland are briefly 

 reported in which the improvement of pastures treated with different fertilizers was 

 tested by pasturing sheep on sample plats. Definite conclusions were not drawn and 

 the experiments, it is stated, will be continued. 



Equipment for breeding, feeding, care, and management of swine, R. S. 

 Shaw (Michigan Sta. Bid. 223, pp. 98-116, figs. ..', dgms. 1%) . — The college piggery is 

 described and details of plans for the construction of buildings, cots, yards, fences, 

 etc., are given. 



Forage crops for swine, R. S. Shaw (Michigan Sta. Bui. 223, pp. 117-124, figs. 3). — 

 Tests of the feeding value of a number of forage crops, including a mixture of grains 

 and peas, peas and oats, sugar beets, and mangel-wurzels are briefly reported. The 

 test is regarded as preliminary. 



An analysis of a mixed crop of millet, rape, corn, oats, and peas is reported, but 

 no data are given regarding the gains made by the pigs pastured on the crop. The 

 mixture when used as a soiling crop for dairy cows gave excellent results and the 

 small amount of rape present apparently had no effect harmful on the milk. When
