Weight of 4 pigs January 6 130 lbs. 



Weiglit of 4 pigs March 28 311 lbs. 



Gain in 81 days . 181 lbs. 



Corn meal consumed in 81 days 524 lbs. 



Pounds meal per pound growth 2.9 lbs. 



Area of 1st gTowtli rape grazed 13,912 sq. ft. 



This is at the rate of 570 pounds of growth in live 

 weight afforded by one acre of first-growth rape as- 

 sisted by 1641 pounds of corn meal. If we assume that 

 5 pounds of com meal made one pound of growth we 

 have left. 242 pounds of live weight, worth |9.68, to be 

 credited to one acre of first-growth rape. 



March 28, the rape having begun to blossom and hav- 

 ing become relatively unpalatable, the hurdles were 

 placed about the rape grazed in January amd part of 

 February, on which the second growth was by this time 

 in good condition for pasturage, though small. 



On this second growth the pigs remained three weeks, 

 meantine consuming the crop on one-sixth acre and 

 eating 168 pounds of com meal. 



The growth made during these three weeks was 82 

 pounds, or one pound of growth for only 2.05 pounds 

 of meal, which figure indicates that the pigs must have 

 derived about half their sustenance from the green crop. 



One acre of second growth rape assisted by 1008 

 pounds of com meal resulted in a gTOwth of 492 pounds. 

 If we again assume a normal requirement of five pounds 

 of grain for ome of growth we have 290 pounds of in- 

 crease in live weight, worth $11.60, as the value of an 

 acre of second crop rape when converted into pork. 



It is fair to add together the gains made on an acre 

 each of first growth and of second growth, since part 

 of the area was grazed twice. This gives a growth of 

 512 pounds of pork then worth |20.48, as attributable
