166 EXPERIMENT STATION RECORD. 



slaughter test was made with 13 crossbred Berkshire pigs with consid- 

 erable Meisen blood, all from one litter, and 2 crossbred Berkshire 

 pigs without Meisen blood. Part of the pigs "were castrated much later 

 than the other. Several of the sows were spayed. The pigs were fed 

 under the same conditions from birth. They were fattened and slaugh- 

 tered when about 10 months old. 



The results of the experiment confirm the opinion that crossbred 

 swine with a large percentage of English blood are not unfitted for the 

 production of a desirable quality of meat. Spaying had no effect on 

 the growth or quality of the meat. 



Experiment to compare the feeding value of dried grains and 

 other home-made fodders with that of linseed cake, Milne ( Trans. 

 Highland and Agl. Sot: Scotland, 5. ser., 7 (1895) pp. 459-469).— -Three 

 tests were made at Mains of Laithers to compare dried brewers' grains 

 and similar products with linseed cake. 



The first test was made with 3 lots of 8 Irish heifers about 2 years 

 old. Each lot was fed about 60 lbs. of rutabagas per head, daily. 

 In addition lot 1 was fed 6 lbs. of linseed cake, lot 2 3 lbs. each of dried 

 brewers' grains and decorticated cotton-seed cake, and lot 3 clover and 

 rye grass hay ad libitum. The test lasted 14 w r eeks. Lot 1 gained 1.4 

 lbs., lot 2 1.54 lbs., and lot 3 0.93 lb. per head daily. 



The second test was made with 3 lots of 4 Irish steers, and lasted 10 

 weeks. All the steers were fed 60 lbs. of rutabagas, and in addition 

 lot 1 was given 6 lbs. of linseed cake, lot 2 6 lbs. of dried brewers' 

 grains, and lot 3 3 lbs. each of decorticated cotton-seed cake and bar- 

 ley bran per head per day. Lot 1 made a daily average gain of 1.95 

 lbs., lot 2 of 2.68 lbs., and lot 3, of 2.06 lbs. per head. 



The third test was made with 44 Irish steers divided into 5 lots of 8 

 each and 1 lot of 4. Lots 1 to 5 were fed 30 lbs. of yellow turnips per 

 head per day and oat straw ad libitum. In addition lot 1 was fed lin- 

 seed cake; lot 2 wet brewers' grains, decorticated cotton seed cake, 

 and linseed cake; lot 3 dried brewers' grains and decorticated cotton- 

 seed cake; lot 4 dried brewers' grains (special); and lot 5 meat meal, 

 barley, and linseed cake. The various grain rations were so arranged as 

 to contain approximately equal quantities of nitrogenous material and 

 fat, and 8 lbs. per head daily were fed. Lot was fed barley bran and 

 oat straw. The test lasted 4 months. The composition and cost of the 

 feeding stuffs are given. Lot 1 gained on an average 31.5 lbs. per head 

 per month, lot 2 33 lbs., lot 3 23.5 lbs., lot 4 35 lbs., lot 5 34 lbs., and 

 lot 6 36.5 lbs. 



Feeding with linseed cake was found to be the most expensive, the 

 average cost being $1.38 per head per week. The lot fed with the 

 special dried brewers' grains was fed the cheapest, the cost being 93 

 cts. per head per week. 



The conclusion is reached that there is no special value in linseed 

 cake as compared with other concentrated feeding stuffs, and that
