986 EXPERIMENT STATION RECORD. 



weight for the 4 lots was as follows: At Ferney, lot 1, G9.2 lbs.; lot 2, 

 67.3 lbs. ; lot 3, 59.G lbs., and lot 4, G1.5 lbs. At Whitelaw, lot 1, 07.7 lbs. ; 

 lot 2, 67.4 lbs. ; lot 3, 61.5 lbs., and lot 4, 61.8 lbs. The experiments are 

 discussed in considerable detail. 



" The results of the experiment are satisfactory, in that they show that there is very 

 little difference in the feeding effect of linseed cake on the one hand and a mixture 

 of cotton cake and dried grains on the other, when given to sheep in as great quan- 

 tity as they can consume along with a full supply of turnips. As regards a mixture 

 of oats and barley and a mixture of oats and maize, these also are fairly equal in 

 feeding effect when given in equal quantities, although on the whole the advantage 

 lies with the latter mixture. But oats, barley, and maize are evidently much inferior 

 to the more concentrated by-fodders cotton cake and dried grains and linseed cake, 

 and, as prices usually go, there is no economy whatever in feeding sheep with oats 

 and barley. It would be better to sell these and buy concentrated fodder with the 

 proceeds. The amounts of loose tallow and wool deserve notice. At both farms 

 lots 1 and 2 produced the most wool, showing that the more highly nitrogenous 

 dietary is favorable to wool production ; and it is noteworthy that the oats-and-maize 

 lot produced most tallow and least wool at both farms, not only on this occasion but 

 also in the case of the former experiment." 



The by-products of the dairy, F. B. Linfield ( Utah Sta. Bui. 5f, 

 pp. 197-249 ', figs. 9). — In the author's opinion the usual methods of feed- 

 ing pigs at creameries on milk or whey alone and finishing on grain 

 for a short period is not satisfactory. Experiments were therefore 

 undertaken to determine the value of skim milk and grain fed in various 

 ways for pigs and calves. 



Experiments in pig feeding (pp. 197-236). — Seven tests are reported 

 extending over a number of years. The object was to compare the econ- 

 omy of feeding milk alone and in combination with grain as compared 

 with grain alone. No comparison was attempted of the different grains 

 fed. The composition of the foods used is reported, some of the analyses 

 being made at the station. The first test which began June 27, 1894, 

 covered 161 days, and was made with 2 lots of 4 and 1 lot of 2 pigs. 

 Lot 1 was fed a ration of 1 lb. of grain to 4 of milk for the first 118 days 

 and 1 lb. of grain to 2 lbs. of milk until the close of the test. Lot 2 

 was fed 1 lb. of grain to 2 lbs. of milk for 118 days and 1 lb. of grain to 

 1 lb. of milk for the remainder of the test. Lot 3 was fed grain mixed 

 with water. For about three-fourths of the test the grain consisted of 

 barley and bran 1:1; during the remainder, corn and wheat 1:1. The 

 second test began January 5, 1895, and covered 135 days. It was made 

 with 2 lots of 4 pigs each. Lot 1 was fed 4 lbs. of skim milk to 1 of 

 grain until the pigs averaged 100 lbs. The proportion of skim milk 

 was decreased as the pigs increased in weight until the pigs averaged 

 200 lbs., when they were fed skim milk and grain in equal amounts. 

 Sufficient water was added to the grain to make up for the skim milk 

 omitted. Lot 2 was fed grain mixed with water. The grain fed both 

 lots consisted of wheat and bran 1:1. The third test, which began 

 August 5, 1895, and covered 175 days, was made with 2 lots of 2 pigs 

 each. Lot 1 was fed 6 lbs. of skim milk to 1 lb. of grain until the pigs
