The culling rate for both New England and New Hampshire varied 

 considerably from 1945 through 1954 (Table 3). The rate reflects both 

 the technological status of dairy cow management and the relationships 

 between the prices for resources used in dairying and the prices for dairy 

 products. The variation in the culling rate indicates that, although many 

 animals must be culled for disease or other reasons, there is some leeway 

 when it comes to culling cows because of low production. The question of 

 whether to cull a cow based solely on her production depends on the quality 

 of animals available for replacement and the price relationships between 

 milk, cull cows, and replacement stock.
