EooTs V. Silage for Dairy Cows. 



[Oct., 



received silage in the last four weeks. In this way it was hoped 

 as far as possible to eliminate differences due to the individuality 

 of the cows. After they had been under experiment for four 

 weeks, when the first part of the experiment was over, an 

 intervening week was allowed fending 27th February) to 

 enable the cows getting silage to become accustomed to the 

 root diet and vice versa. The records of this intervening week 

 were not taken into account. In the preliminary week ending 

 23rd January, the cows getting root had 14 lb. of chaffed straw 

 and the cows getting silage 7 lb. , but it was found that the root 

 lot were not eating up their chaff, so it was decided to feed 

 both lots with 10 lb. of chaff during the whole experimental 

 period. It was found that both lots of cows ate up their food 

 well. The total quantity of concentrated food fed to the six 

 silage cows was 4 lb. x 6 = 24 lb. This food, however, was not 

 equally distributed, the cows giving more milk receiving rather 

 more of both concentrated and coarse food, whilst those giving 

 less milk received less food. The average daily ration of silage 

 and root cows, however, was that given previously, the foods 

 being measured and weighed daily in bulk for each lot. It was 

 considered that this method was the best, in view of the vary- 

 ing milking capacity of the cows. 



The composition (crude) of silage taken is that of the actual 

 sample analysed by Mr. Mansfield.
