THE MANAGEMENT AND FEEDING OF THE 

 BREEDING HERD IN THE WINTER 



It is during the winter, in most of the pork-producing 

 sections, that the problems of housing and management, 

 sanitation, exercise, and feeding, become of more than 

 usual importance. With cold weather, frozen ground, 

 and dry feeds, the breeding herd is under conditions 

 which make it more difficult to maintain good health. 

 The problems involved in the successful management of 

 the herd during the winter directly affect the results in 

 economy of maintenance and in the number and quality 

 of the pigs produced. 



GENERAL MANAGEMENT 



An item of first importance in the winter management 

 of the breeding herd is its proper grading. Only those indi- 

 viduals whose requirements for feed and general care are 

 the same should be together. The effects, for example, 

 of allowing the pregnant sows to run with the fattening 

 shotes is to jeopardize greatly the chances of a good pig 

 crop in the spring. Hogs that are being fattened for 

 market do well in restricted quarters, and with full fatten- 

 ing rations. It is impossible for the pregnant sows under 

 these conditions to produce healthy, vigorous pigs or to 

 nurse them properly after birth. The sows demand a
