Report on experiments in pig rearing in 1912, 1913 and 1914. To allow 

 of comparing these results with those already set out in the previous bul- 

 letins of the same Station, there were adopted (in all cases where not other- 

 wise indicated) the same unit prices as in previous years, namely :

Winterins, old brood Sous. — It was desired to make a comparison be- 

 tween a ration of chopped lucerne hay mixed with an equal weight of ground 

 grain, and of feeding the lucerne hay in a rack {ad libitum) and shelled maize 

 in a trough. Each ration was given to 10 sows from the beginning of No- 

 vember to INIarch (average 121 daA-s) in four consecutive years. It is prov- 

 ed by the average of the fottr years that 9.9 bushels of maize and 86 lbs 

 of lucerne hay, or 8. 84 bushels of maize and 495 lbs of chopped lucerne hay 

 were required to maintain a sow weighing 3S7 lbs during 4 winter months 

 and to increase its live weight by about 95 lbs. The feeding of a light 

 grain ration and of lucerne hay ad libitum was found to be more economical 

 than the feed with which it has been compared. 



Wintering young brood Soivs. — During 5 consecutive winters gilts 

 «ere given ad libitum a mixture of i part by weight of chopped lucerne hay 

 with 2 or 3 parts of grain. The pioportion of grain was reduced when the 

 sows looked like becoming over-flesh^^ Each group comprised 20 to 25 

 sows. The experiments began about the loth November and ended about 

 the end of ^Nlarch or beginning of April, a little before littering. There was 

 found on the average :
