The failure to raise a large, healthy litter at weaning 

 time is one of the most common causes of unprofitable 

 production. The costs of a litter of 8 or 9 pigs at wean- 

 ing time are but little greater than for a litter of 4 or 5. 

 We are all familiar with the effect which the strength 

 and health of pigs at weaning time has on economical 

 gains that follow. Good management and proper feed- 

 ing are needed to produce a large, strong litter. 



Swine research has definitely shown that gestation and 

 lactation are critical feeding periods. The following 

 items are greatly influenced by the ration of the sow: 



1. The condition of the sow at farrowing and her 

 performance during lactation. 



2. The number of pigs farrowed alive. 



3. The health and strength of pigs farrowed. 



4. The number of pigs weaned. 



5. The health and strength of pigs weaned and 

 subsequent growth. 



6. The condition of the sow at weaning. 



Until recently it was thought farm grains supplemented 

 with proteins and minerals constituted a satisfactory 



ration for the sow. However, using the weight of the 

 Utter at weaning time as a measuring stick, the fact 

 has been definitely established that many vitamins are 

 also needed to make this ration adequate. BLUE SEAL 

 SOW SUPPLEMENT has been formulated to include 

 not only high quality proteins and minerals, but also 

 the vitamin carriers demanded in this critical stage of 

 swine feeding. Good management and BLUE SEAL 

 SOW SUPPLEMENT insure large, strong litters.
