MARKET CLASSES AND GRADES OF LIVESTOCK 35 
The weight selection in pigs is probably as important as in hogs. 
A certain class of trade requires lightweight cuts of fresh pork, which 
must be supplied by pigs of certain weight. In the feeder and 
stocker group buyers also discriminate sharply between different 
weights, such discrimination depending largely on the preference of 
individual feeders and on the kind and quantity of the feed avail- 
able. 
Grades of pigs are fairly comparable with those of hogs although 
it will be noted that prime grade is lacking and that cull or inferior 
grades appear in each weight group. This is what might be ex- 
pected in view of the light weight and immaturity of pigs. No 
grades appear in roaster pigs since they are not usually sold on a 
oraded basis. Weight is the price-determining factor in most. 
imstances. 
SHEEP 
Sheep are animals of the ovine species sufficiently mature to have 
acquired at least the first pair of permanent teeth. This usually 
occurs when the animal is between 10 and 15 months of age. 
As a market commodity sheep are now relatively unimportant. 
At most markets sheep do not constitute more than 15 per cent 
of total receipts of ovine stock, and at times they amount to less 
than 10 per cent.
