Pork Production 



As bearing on the same point, the number of pigs 

 farrowed dead or immature in litters of different sizes 

 is also instructive. The author is indebted to W. J. 

 Carmichael 1 of the Illinois Experiment Station for these 

 data which are presented in Table XX. 



TABLE XX. EFFECT OF SIZE OF LITTER ON NUMBER OF 

 DEAD OR IMMATURE PIGS 



Although a larger number of dead or immature pigs 

 is farrowed in litters containing ten or more pigs than less, 

 it would appear that in litters smaller than ten the number 

 of pigs farrowed dead or immature is not greatly affected. 

 When the proportion of dead or immature pigs is con-

 larger litters, up to ten, than in the smaller ones. When 

 the number of pigs to the litter exceeds ten, however,
