FOODS ANIMAL PRODUCTION. 251 



The following conclusions were readied : " So far as the actual feeding 

 was concerned, and leaving out of account for the time the manurial 

 values of the foods, the best feeding return was given by the mixture 

 of linseed cake and barley in approximately equal quantities, while the 

 least satisfactory return accrued from the use of linseed cake and wheat 

 in ai)proximately equal x)roportions." Under the then existing condi- 

 tions the author believes that" when both feeding and manurial results 

 were taken into consideration, [there was] a slight advantage of about 

 18 cts. per head in favor of feeding with linseed cake and barley in 

 equal quantities as against the same total in the form of linseed cake 

 alone. . . . 



"A further i^oint brought out in this series of experiments is the 

 decidedly more favorable return derived from sheep feeding as compared 

 with bullock feeding." 



On an experiment in calf feeding, A. Gouin {Jour. Agr. Prat., 60 

 {1896), J, Ko. 26^ p. 931). — The author gives a brief account and criti- 

 cism of some experiments on calf feeding made at the ficole Pratique 

 d'Agriculture de Saint-Bon. Nine calves from 3 to G months old were 

 divided into 3 lots of 3 each, the average weight in lot 1 being 226 kg., 

 in lot 2, 187 kg., and in lot 3, 115 kg. All were fed a ration of 1 kg. of 

 hay, 5 kg. of beets, and 500 gm. of rye per 100 kg. live weight. In addi- 

 tion, lots 1 and 3 were fed 250 gm. of rape-seed cake and lot 2 500 gm. 

 of bran. The experiment continued 70 days. Lot 1 gained 26 per cent 

 of their initial weight, and lots 2 and 3 gained 20 per cent. 



The conclusion was reached by the experimenters that while the per- 

 centage gain was practically the same, there was an advantage in using 

 rape-seed cake where its cost was not more than double that of bran. 

 The author criticises the method of calculation followed in the Saint-Bon 

 experiments. He believes that more trustworthy results are obtained 

 by computing the gains per day rather than the total percentage gain. 



Fattening lambs in winter, T. Shaw {Minnesota Sta. Bui. 4i, pp. 

 280-295). 



Synopsis. — A feeding test was made (1) to determiue the relative value of fattening 

 lambs in yards, in sheds -with access to yards, and confined in slieds; (2) to com- 

 pare a limited and an ad libitum grain ration ; (3) to determiue the relative value 

 of wheat screenings and oil cake and wheat and oil cake as a grain ration, and 

 (■1) to see if lambs can be profitably fattened nnder the prevailing conditions. 



The test, which began November 19 and continued 117 days, was 

 made with 30 wether and 10 ewe lambs, averaging 76;^ lbs. The lambs 

 were grade Shropshires and purchased in the neighborhood. They 

 were divided into 5 uniform lots containing 6 wethers and 2 ewes. 

 Lot 1 was kept in a yard on the sunny side of a building. Lots 2, 3, 

 and 1 weie fed indoors, but were allowed to run in a yard. Lot 5 was 

 confined in a barn. The lots were fed all the hay they would eat with- 

 out waste. Lots 1, 2, 3, and 5 were fed in addition wheat screenings 

 and oil cake in tlie proi)ortion of 9 to 1 and lot 1 wheat and oil cake in 

 the same proportion. The lambs were fed twice a day. Lots 1, 3, l,
