LIVE AND DEAD WEIGHT OF PIGS. 



191 



We have no doubt that a highly refined pig of any of 

 the small breeds, well fed during its whole growth, and 

 thoroughly fattened, will shrink less than 10 per cent on 

 its fasted live weight. 



Messrs. Lawes and Gilbert accurately ascertained the 

 live and dead weight of the fifty-nine pigs on which their 

 experiments, previously alluded to, were made. The ac- 

 tual, average live weight, after fasting, of the whole fifty- 

 nine pigs, was 212 3 1 4 Ibs., and the average dressed weight, 

 176 Ibs., 5.3 oz., or a little over 82 1 1 2 per cent. 



The following table shows the actual average weight of 

 the different parts of these fifty-nine pigs, and in the 

 right-hand column we give the per centage weights :

For the sake of comparison, we may say that the 

 average, of 249 sheep, killed at Rothamstead, by Messrs. 

 Lawes and Gilbert, was, fasted live weight, 153 Ibs., 10.2
