328 Bullock Feeding Experiments. 



linseed cake has caused the bullocks to convert a greater pro- 

 portion of their food into beef, so that practically the same 

 amount of food has given considerably more beef when 

 linseed cake formed part of the diet than when any other 

 concentrated food was used. From the point of view, there- 

 fore, of the absolute increase produced by the feeding, 

 linseed cake alone, as an addition to the usual Norfolk diet 

 of chaff and roots, has shown in each of three years a decided 

 advantage over each of the mixtures which have been tried. 



Comparison of the Various Concentrated Foods from the Point 

 of view of Economy. 



The Table on the next page shows the financial result 

 of the feeding of each lot of bullocks in each year, the 

 prices of the cake, etc., used in the calculation being those 

 given in the preceding" table as current at the time of each 

 experiment. The bullocks were killed when ready, and sold 

 by carcase weight. The manurial values are calculated from 

 Sir J. B. Lawes' and Sir J. H. Gilbert's tables of compen- 

 sation values [R.A.S.E. Journal, 1897. IV.) The charges 

 for attendance are those actually paid, and are considerably 

 higher than they would be in practice, on account of the 

 extra labour involved in weighing out accurately all the 

 foods, and attending to other details. 



Adding up the figures for the three years in the cases of 

 Lots I., II., III., where the foods were comparable throughout, 

 it appears that the result of the feeding of the total fourteen 

 bullocks which have been experimented on in each lot during 

 the three years is : — 



14 Bullocks fed as in Lot I. - - - profit £4 10s. iod.

Thus, while, as shown before, linseed cake has caused the 

 greatest rate of increase in every case, the mixture ot 

 decorticated cotton cake and maize meal, or dried grains, 

 used in Lot III., has from a money point of view paid best ? 

 and this result is confirmed by the six years' experiments in 

 sheep feeding which the Chamber had carried out before com- 

 mencing their work in bullock feeding. In the sheep feeding
