Cattle-Feeding Experiment. 



An experiment to compare the feeding values of decorticated 

 cotton cake and cotton seed meal was made in the winter of 

 1 901 -1902 on the farm at Lledwigan attached to the Agricul- 

 tural Department of the University College of North Wales, 

 Bangor. 



For the purpose of the trial six Welsh bullocks were selected 

 in November, from a herd of 24, which had been grazing 

 together during the summer. They were put into boxes and 

 similarly fed till the commencement of the experiment on 

 December 13th. The bullocks were equally divided into two 

 lots of three each, and at the beginning of the experiment the 

 following daily rations were fed to them : — 



Lot I. 



4 lb. cotton seed meal 



4 lb. maize meal 

 70 lb. pulped swedes 



10 lb. hay and straw chaff 



5 lb. long hay 



water 



Lor II. 



4 lb. decorticated cotton cake 



4 lb. maize meal 



70 lb. pulped swedes 



10 lb. hay and straw chaff 



5 lb. long hay 



water 



After January 6th the concentrated food given to each lot was 

 brought up to 10 lb. per bullock per diem by the addition 

 of 1 lb. to the cotton cake and maize meal in Lot I., and to the 

 cotton seed meal and maize meal respectively in Lot II. 



The prices of maize meal, cotton seed meal, and decorticated 

 cotton cake were £6 17s. 6d., £j 5s., and £7 12s. 6d. per ton 

 respectively. 



The bullocks were weighed at the beginning of the experiment 

 and at its conclusion on February 28th. The particulars of the 

 weighings are given in the following table : —
