132 CONTINUOUS CROPPING 



The other kinds of winter forage pasture mentioned 

 all contain either clover or vetch, and these crops supply 

 the essential albuminoids which, in the absence of 

 separated milk, the dietary would otherwise lack. 



Depending on the weight of the crop grown, it will 

 require four acres to summer feed thirty pigs in 

 this manner, but food from the same plots, as already 

 indicated, would be available in spring, autumn, and a 

 good part of the winter for other stock. 



A NETT PROFIT OF £l^ PER ACRE 



The value of the food produced from the winter 

 pasture, consumed by stock other than pigs, would 

 more than cover the entire cost of growing the winter 

 pasture, so that from the pigs alone a clear profit of £15 

 per statute acre is obtained, the value of the pig 

 manure produced being put against the attendance. 



The thirty pigs would not be given the run of the 

 whole four acres, but be folded on about an acre at a 

 time, and the fold changed every fortnight. By the 

 time the fourth acre was eaten down, the first acre 

 folded would be ready again. 



In practice I find it a very good plan to alternate the 

 folding of pigs with sheep and young stock. Weanling 

 calves do remarkably well on a forage pasture, 

 especially rape, or rape and vetches mixed, whilst 

 the value of this feeding for sheep is already well 

 known. 



In the folding of pigs, ordinary strong wire-netting 

 is used, but one strand of barbed wire should be run 

 inside the netting, and about 6 inches from the floor, to 

 keep the pigs from trying to get under the netting. 

 Further, the pigs should be rung to prevent rooting. 

 Tliey should also be provided with a rough shelter from 

 the sun, and accustomed to a little green feeding before 

 being turned out on the crop.
