months without any ill-effects resulting. It is also 

 necessary to bear in mind that during the winter period 

 indoor cattle are fed on much less laxative food than 

 the green soiling crops, which it is intended to use in 

 summer. The farmer may, therefore, disabuse his 

 mind of the idea that outdoor exercise such as is 

 provided under the pasturing system is essential. 

 Under the summer soiling system, however, as will be 

 seen in future chapters, outdoor exercise for the 

 animals is not precluded. 



THE WINTER FOOD SUPPLY 



For the winter feeding of the farm stock we shall 

 have available the crops produced in the second year's 

 break, consisting of 4 acres of tare hay, followed by 

 4 acres of winter forage crops (" winter greens "), 

 4 acres of roots (say, 2 acres of mangolds and 2 acres 

 of potatoes), grown in the third year's break, together 

 with 4 acres of tare hay and 4 acres of seeds hay or 

 ensilage grown in the fourth year's break. We may 

 tabulate our supply of winter food as follows : —

CO-OPERATION NECESSARY FOR ECONOMICAL 

 PRODUCTION 



As will be seen later when we come to discuss con- 

 tinuous-cropping rations, the above amount of food 

 would be more than is necessary for the feeding of our
