DATA IN CATTLE-FEEDING 229 



Relation of Concentrated Pood consumed to 

 Beef produced. 



With an average daily ration for a two-year-old 

 bullock of 8 Ibs. cake, 17 Ibs. straw, and J cwt. roots per 

 day, the average increase in live weight should be about 

 J cwt. per month, or 2 Ibs. per day. In Mr Bruce's 

 report (1906) the average increase per month was 

 56-6 Ibs. per bullock. 



At this rate : 



4^ cwts. cake give i cwt. increase in live weight. 

 100 Ibs. 14 Ibs. beef (60 per cent, carcass). 

 57 Ibs. 8 Ibs. 



Every J cwt. of cake fed to fattening bullocks should 

 therefore give approximately a Smithfield stone of beef 

 (8 Ibs.) 



Cost of producing Increase in fattening Bullocks. 



With liberal feeding for two-year-old bullocks of 

 8 Ibs. cake per head per day along with straw and roots, 

 the cost of producing increase would be approximately 

 as follows : 



Costs ^2, 55. to 2, 153. in cake, straw, and roots, to give i cwt. 

 live weight increase. 



Costs about 2 in cake, straw, and roots, to give i cwt. live weight 

 increase when manurial residue is taken into account. 



Costs about ;i, IDS. in cake, etc., to give i cwt. live weight 

 increase when both manurial residue and enhancement in 

 value of store weight of animal (say, 55. per live cwt.) is 

 taken into account, which must be credited to the food. 



Bullocks should increase in value from i, 55. to 

 i, IDS. per month, if they are to leave a profit.
